　　People’s Daily Online, San Francisco, April 20 (Han Shasha) Every Wednesday morning, the citizens of Fremont, San Francisco Bay Area, California, USA always push out three roller trash cans with different colors that are usually placed in the yard, and open them in front of the street in a row.

　　As the garbage trucks rumble past, these garbage cans placed on the street are classified, dumped and transported away.

　　Trash cans of different colors have their own uses. In this city, gray trash cans are used to hold renewable garbage, such as wine bottles, beverage bottles, cans, clean waste paper, etc. Blue trash can is used to hold non-recyclable garbage, such as leftovers, vegetable roots and peels and other kitchen waste; Green trash can is used to hold garden garbage such as weeds and pruned branches in the yard.

　　This is a microcosm of the classification of domestic waste in California. Although each city gives different "connotations" to trash cans with different colors, and the time for recycling garbage once a week is not the same, garbage sorting has been deeply rooted in people’s hearts and become a daily routine.

　　Specialized companies provide garbage collection services in a unified way.

　　The garbage classification system in the United States is a mature and perfect system, which includes not only the front-end classification carried out by residents in daily life, but also the back-end recycling, landfill treatment and degradation, so as to realize the reduction, harmlessness and resource utilization of domestic garbage.

　　Residents’ classification of domestic waste is the basis of the whole system engineering. Every city has a clear explanation, education and promotion activities for garbage classification. On the official website of the city, residents can consult various information such as specific garbage recycling plans and garbage classification. In addition to common household garbage, including toxic household cleaners, paint thinners, pesticides, fluorescent bulbs and tubes containing mercury, thermometers and thermostats, electronic waste and vehicle batteries, household harmful waste is not allowed to be put into the roadside roller trash can. Because domestic harmful waste contains toxic substances, if it is not handled properly, it will harm human beings and the environment. These harmful waste must be placed in the designated recycling place and cannot be discarded at will.

　　The sorted garbage is collected by a special garbage recycling company on a fixed date, and residents pay a certain amount of "garbage clearing fee" every month. Individuals are strictly forbidden to rummage through the available items in the trash can without permission, otherwise it will be treated as theft. There are more than 20,000 garbage recycling companies in the United States providing services to different cities. Take San Francisco as an example. Recology is a service company in this city. Residents receive three 32-gallon garbage bins free of charge, and pay the service fee of $35.18 per month to the company, which provides regular garbage removal service.

　　Usually, garbage recycling companies will reclassify domestic garbage in different ways and recycle it reasonably. Renewable plastics, metals, waste paper and glass will be sorted, recycled and reused; Burning combustible materials to generate electricity; Decomposable organic matter is fermented to make organic fertilizer; Inorganic waste is used to pave the road. In recent years, garbage recycling companies have reprocessed domestic garbage in a more optimized way, and often use organic garbage gasification to generate electricity; Pyrolysis and incineration of pollutants, incineration and heating, gasification and power generation, purification of water and gas residue, etc. According to the website of Luyuan Recycling Company, food waste in San Francisco was transported to a nearby factory and turned into valuable fertilizer. Some finished fertilizers are sold to vineyards in Napa wine country.

　　Residents who litter may go to jail.

　　The strict implementation of garbage sorting in the United States is inseparable from the government’s education and promotion and detailed laws and regulations.

　　The Resource Conservation and Recovery Act is the basic law for the management of solid and hazardous wastes in the United States. On October 21, 1976, the US Congress passed the law reform to deal with the growing problem of urban and industrial waste. This law is divided into three parts, which respectively put forward requirements for the management of solid waste, hazardous waste and underground storage of hazardous waste. The focus of this law is the control and management of hazardous waste. In order to cooperate with this law, the US Environmental Protection Agency has formulated hundreds of regulations, plans and guidelines on the discharge, collection, storage, transportation, treatment, disposal and recycling of solid waste and hazardous waste, forming a relatively complete system of solid waste management laws and regulations.

　　In addition to federal laws, each state also has its own laws and regulations. Littering is a crime in America. Every state has laws prohibiting littering, and littering is a third-degree misdemeanor, punishable by a fine ranging from 300 to 1,000 dollars, imprisonment or community service (up to one year), or a combination of two or three of the above.

　　San Francisco, California, USA has made remarkable achievements in garbage sorting, recycling and reuse, with a garbage recovery rate of 80%, which is called "green city in green state". Siemens conducted a study in 2011, and the results were published in the "Green City Index". By comparing the sustainable development performance of 27 major American and Canadian cities, San Francisco was rated as the greenest city in North America and ranked first in garbage management.

　　This result is closely related to the California government’s advanced environmental awareness and the promulgation of a series of bills. As early as 1921, the government of San Francisco required that garbage recycling must be managed by companies, and individual garbage recycling behavior should be banned, thus resulting in "Sunset Cleaning Company" and "Cleaners Association", which is now the Luyuan Recycling Company in San Francisco. In 1989, the city of San Francisco passed the "Comprehensive Waste Management Act (AB939)", requiring all administrative districts to achieve 50% waste disposal by reduction and recycling before 2000. Regional managers who failed to meet the requirements were fined $10,000 per day. At the same time, the household is taken as an independent individual to carry out classified garbage collection, and institutions regularly come to collect recyclable items, and the sales proceeds are used to cover the garbage disposal expenses.

　　According to this law, California has set up a "Unified Management Committee for Municipal Waste" to specifically guide and supervise the implementation of various tasks, with the aim of making people fully aware of the fact that municipal waste is increasing and landfill sites are becoming increasingly scarce.

　　With the passage of time, the San Francisco government’s laws on garbage recycling and classification have become more and more detailed, including the implementation of the "Waste Electrical Appliances Recycling Law" passed by California in 2003, which made specific provisions on the recycling of waste computers, televisions and other audio-visual equipment.

　　In 2009, San Francisco passed the "Compulsory Classification of Garbage", which stipulates that residents must strictly abide by the classification of discarded items, and it is strictly forbidden to rummage through the usable items in the garbage bins without permission, otherwise it will be punished as theft, and at the same time, different levels of fines will be imposed on each household that violates the rules. This was called the most stringent recyclable law in the United States by the media.

　　Why does San Francisco have the confidence to set the goal of "zero waste"?

　　In 2002, the San Francisco City Supervision Committee and the mayor passed a resolution, and it is planned that by 2010, the conversion rate of garbage recycling and composting will reach 75%, and by 2020, "zero waste" will be completely realized.

　　San Francisco is the first city in the United States to set the goal of "zero waste" of garbage, and it is also the first city to force the use of three-color trash cans for recycling and sorting garbage. In 2013, San Francisco has successfully converted 80% of domestic garbage into recyclable garbage or fertilizer.

　　In comparison, the garbage conversion rate in Los Angeles is 65% and that in Seattle is 50%. According to the data of the US Environmental Protection Agency, in 2014, about 258 million tons of domestic waste was generated in the United States, and more than 89 million tons of garbage was recyclable and compostable, which was equivalent to a recovery rate of 34.6%, and 136 million tons of garbage was landfilled. Internationally, at the end of 2013, the EU’s garbage recycling and composting conversion rate was 42%.

　　The success of the "San Francisco Experience" is related to the radical and harsh government policies of the city. In addition to the above-mentioned series of laws and regulations, this city is the first city in the United States to ban the use of polystyrene foam in food service (2006), requiring mandatory recycling of construction waste (2007), prohibiting free provision of plastic bags in pharmacies and supermarkets (2009), and implementing mandatory garbage recycling and composting classification for residents and enterprises (2009).

　　In addition, there is a public-private partnership garbage collection system. Luyuan Recycling Company, which serves the city of San Francisco, is a private enterprise. In the process of providing services to San Francisco, there was no bidding and no payment to the government. The monthly service fees charged to residents and the profits generated by garbage sorting belong to the company. In 2012, the city of San Francisco once held a vote, and planned to break down garbage collection into five businesses to bid separately. But at that time, this proposal was opposed by 77% of voters.

　　San Francisco’s garbage classification can be deeply rooted in the hearts of the people, and it is inseparable from the government’s efforts to promote it widely. In order to better implement waste sorting and achieve the goal of "zero waste" in 2020, the environmental protection department of San Francisco specially promotes the publicity and education activities of waste reduction and sorting among young people; Introduced the family design concept of environmental protection garden, founded the San Francisco environmental protection foundation and the San Francisco organic food community; And promote environmental protection organizations in San Francisco community college and universities in San Francisco; Through posters, newspapers, the Internet, public transportation and other media, the publicity and promotion activities of urban garbage control have been carried out for a long time.

　　Whether San Francisco can achieve "zero waste" in 2020 is still unknown, but at least some experiences of the city can be used for reference.

　　Recently, Qiu Jiduan, an alumnus of Beijing Normal University, donated his 6,000 pieces of ancient ceramics to his alma mater, Beijing Normal University, and the school announced the establishment of Qiu Jiduan’s China Ancient ceramics museum. However, this seemingly ordinary donation has aroused doubts from the cultural and historical circles, and some people in the industry have questioned that these 6,000 collections are "fakes". Some experts and scholars pointed out that it is very serious for universities to build museums, and it is suggested that the above donations should be strictly checked before collection and exhibition. "Before the donation, there should be a third-party and credible appraisal unit to participate. If the university establishes a museum, it should go to the cultural protection unit for filing."

　　A related person from the Beijing Municipal Bureau of Cultural Relics told the Beijing Youth Daily reporter that no application for filing has been received from Beijing Normal University. As for whether the collection widely questioned by the outside world has been professionally appraised by a third party, as of press time, the Education Foundation of Beijing Normal University has not given a response.

　　Alumni donated 6,000 pieces of ancient ceramics and were accused of being "counterfeit"

　　On July 13th, Qiu Jiduan, a Hong Kong industrialist and alumnus of Beijing Normal University, donated 6,000 pieces of ancient China ceramics to his alma mater, Beijing Normal University. According to media reports, these collections include representative ceramics from the Han, Wei and Jin Dynasties to the Song, Yuan, Ming and Qing Dynasties, and many of them are rare and unique in China. Beijing Normal University announced the establishment of China Ancient ceramics museum and China Ancient Ceramics and China Ancient Civilization Research Institute, and appointed Qiu Jiduan as the first curator and dean of the research institute. This is not the first time that Qiu Jiduan donated to Beijing Normal University. In 2006, he donated 20 million yuan to build the Qiu Jiduan Gymnasium.

　　At the meeting, Qiu Jiduan made a speech and said "I am confident that the collection will reach more than 10,000 pieces". School leaders revealed that the construction of museums and research institutes has been put on the agenda, and will be built in Xueyuan Road Campus, covering an area of more than 10,000 square meters. "It will not only become a learning and research center for teachers and students in the school, but also serve as a talent training center". Subsequently, the official website of Beijing Normal University, WeChat WeChat official account, Weibo and major media reported the donation ceremony.

　　However, after the news came out, the domestic art collection community was in an uproar. Many online museum lovers and people in the field of folk collections are not optimistic about this donation, and question the authenticity of the collection and the procedures for building the museum. WeChat official account, named "Beijing Muming Century Cultural Relics Appraisal Co., Ltd.", wrote "Beijing Normal University, your underwear has dropped", saying that ceramics are presumed to be fakes according to the photos of Qiu Jiduan’s warehouse and the photos of Xiamen’s public exhibition in Fujian.

　　Another article titled "The estimated market price of the donated treasures of Beijing Normal University is 1.2 trillion yuan! — — If it’s all true, the article is also circulated in the circle of WeChat friends. This article compares and evaluates the ceramic pictures of Qiu Jiduan’s collection on some occasions with the ancient ceramics appearing in museums such as auction houses and the Forbidden City, and questions the authenticity of the collection donated by Mr. Qiu from the opposite side.

　　dispute

　　Qiu Jiduan responded twice a week: he had been identified by experts before donation.

　　What was originally a happy alumni donation triggered an unexpected public opinion storm. Qiu Jiduan, a donor, responded twice in a week in response to the voice of doubts raised by the Internet.

　　On July 18th, Qiu Jiduan said through the media that the current collection is only the tip of the iceberg of China’s porcelain stock, which can’t fully represent the overall level of China’s porcelain, and the cognitive level of some experts in the field of ancient ceramics identification is also limited by this. Qiu said that individuals only rely on photos as evidence to question the authenticity of their collections without seeing the real objects of their donations, which seriously disturbs the audio-visual perception. He said that it was normal to produce hundreds of thousands of pieces of porcelain every year in ancient times, but there were only a handful in museums, but porcelain could not be oxidized and disappeared; The official kiln itself was a valuable currency in that year, and the folk circulation was very large.

　　On July 20th, the Education Foundation of Beijing Normal University published the article "Qiu Jiduan signed an agreement with Dacheng Law Firm" through official WeChat, which stated that Qiu Jiduan authorized Qian Weiqing, a lawyer of Beijing Dacheng Law Firm, to defend the rights related to the donation of 6,000 pieces of ancient ceramics to Beijing Normal University.

　　The reporter of Beiqing Daily learned from the statement issued by Dacheng Law Firm that Qiu Jiduan’s donation of porcelain to Beijing Normal University will be visually appraised by a qualified institution recognized by the recipient, or by a team of more than four qualified experts in porcelain appraisal: after being appraised by trace and spectrum, it will be included in the donation after judicial appraisal and the recipient has no objection. The statement also stressed that "anyone who slanders without evidence will be investigated for legal responsibility according to law."

　　The industry questioned that porcelain was "ridiculously fake"

　　Require the disclosure of the list of "appraisal experts"

　　The reporter of Beiqing Daily contacted Chu Mu, the author of the questioning article "Beijing Normal University, your underwear fell" mentioned at the beginning, and the general manager of Beijing Muming Century Cultural Relics Appraisal Co., Ltd., and asked how he initially doubted the authenticity of the porcelain donated by Shang Qiu Jiduan. Chu Mu replied: "In the collection and auction circle, a person’s collection taste can be judged by his warehouse and public exhibits. As soon as the news of Beijing Normal University came out, many experts in our circle questioned it, and the collection of Mr. Qiu’s warehouse circulated on the Internet was definitely a fake, because it was so fake that it was called &lsquo in the jargon; Opening leave ’ 。” He held up an example of porcelain bottle photos in Qiu Jiduan’s warehouse collection circulated on the Internet, and the bottle was printed with "Emperor Zhu Di of Ming Yongle gave King XX a gift". "According to the ancient practice, the emperor’s name should be taboo. At this point, I know it is fake. "

　　Regarding Qiu Jiduan’s statement that "folk ancient porcelain has a large circulation, and the collection is only the tip of the iceberg of China’s porcelain stock, and ceramic experts are limited", Chu Mu replied that Qiu Jiduan’s statement is somewhat confusing, which can’t prove that his folk acquisition is genuine. "One more thing, he said that experts have not seen these, so they dare not recognize it and say it is false. However, in ancient times, more attention was paid to laws and statutes than now. In a society with underdeveloped information, there was a great commonality in what it did, and there were certain rules of the device. You can’t do anything by yourself and say it’s the real thing you haven’t seen. " Chu Mu said.

　　In the face of Qiu Jiduan’s legal statement, Ji Tao, a researcher at the Auction Research Center of the Central University of Finance and Economics, responded in an interview with the reporter of Beiqing Daily: "I have read that statement. As far as the current situation is concerned, we have not seen 6,000 collections in kind. Therefore, he is required to publicly announce the list of more than 4 porcelain appraisers mentioned in the statement and come up with an appraisal report. If the report is recognized by the industry, it will be convincing."

　　During the interview, both of them thought that building a museum was a very serious matter and should be treated with caution. Ji Tao, a researcher at the Auction Research Center of the Central University of Finance and Economics, wrote that the quality of ancient ceramics museum is related to the brand image of Beijing Normal University. It is suggested that experts from all sides should consult and strictly control the collection and exhibition of the donated ceramics. "To run art galleries and museums in universities well, we need the support, participation and joint supervision of the whole society under the protection of the legal system to avoid the emergence of ‘ Confuse the truth with the false ’ 、‘ Distort history ’ 、‘ Misleading teaching ’ With ‘ Mistaken children ’ 。” There should be an impartial third-party appraisal agency and appraisal agency to appraise the collection.

　　trace

　　Beijing Normal University did not disclose whether there was an expert appraisal team this time.

　　The reporter of Beiqing Daily noticed that this is not the first time that Beijing Normal University has built a museum. In fact, as early as 2000, Beijing Normal University established the Museum of Cultural Relics. Different from this time, the museum was established on the basis of the cultural relics room of the history department of the school, which has a history of more than 50 years. According to public information, when the museum was built, the school specially set up a committee with the famous historian Bai Shouyi as the chairman and 14 famous scholars such as Qi Gong and Zhong Jingwen as members, and invited experts from professional institutions such as the Forbidden City, the Chinese History Museum and the Capital Museum to give guidance on exhibition design and content planning of the cultural relics museum.

　　Yesterday, the reporter of Beiqing Daily asked the Beijing Normal University Education Foundation for the details of "donating ancient porcelain". The staff admitted that the WeChat article on the 20th was forwarded by the Foundation, and said that the list of donated collections and all the objects have not yet been delivered. When asked whether the ancient porcelain was professionally appraised by a third party before receiving it, the other party responded "I don’t know much about the situation". When the reporter of Beiqing Daily asked if he could contact the relevant principal, the person said that the school was on holiday now and would contact the reporter later, but as of press time, the Education Foundation of Beijing Normal University did not give a response.

　　The reporter of Beiqing Daily tried to contact the relevant professional teachers of the School of History of the school to inquire about this matter, but the other party did not respond. Many history alumni said that it was inconvenient to talk about this matter.

　　expert

　　China has not yet established a mature university donation system.

　　The reporter of Beiqing Daily interviewed Mr. Xiong Bingqi, Vice President of 21st Century Education Research Institute, about the question that Beijing Normal University was questioned by donations. Xiong Bingqi said that at present, China has not established a mature university donation system, and some universities are easy to "rush" to get donations: "Some schools are eager for quick success and instant benefit." Xiong Bingqi pointed out that some alumni (society) donations are still led by the administration. "The leaders have made a decision outside, and even if they find problems when they are implemented, they have to go ahead." He also suggested that more standardized requirements should be given in the way and process of donation, and it should not be done at will. For example, the board of directors (or Council) will listen to the opinions of teachers and students in advance on the source of donation funds, the place and time of donation title, and the use of donation funds, and then accept them after obtaining the consent.

　　Xiong Bingqi said that in foreign first-class universities, social and alumni donations are very important sources of funding for running schools. Many famous schools such as Yale and Harvard have always attached great importance to alumni donations, and the alumni donation rate is even an indicator for evaluating first-class universities in the United States, because behind alumni donations, the quality of running a school, the relationship with alumni and the level of sustainable development are displayed. "To do a good job in the basic work of the school and improve the level of running a school, the most important thing is to let university donations embark on the road of specialization."

Before Ivey’s film, he pushed a popular science article on screen technology, which attracted everyone’s attention. Today, let’s pay attention to the "behind-the-scenes" that is related to the screening effect-the projector.

　

Film projectors have become a memory for most people, and today’s cinemas have already become the world of digital projectors. Let’s briefly talk about the development history of digital projectors.

Advances in chip technology and resolution

Digital film projectors can be divided into 4K, 2k and 1.3k (obsolete) according to the resolution from high to low, and the core part is the DLP chip.

　

The digital film projector that appeared at the end of last century and the beginning of this century is1.3K(1280×1024, about 1.3 million pixels) resolution.. Its architecture is a DLP projection system with a digital projector head in front of the light box of the traditional film projector, and its imaging device is the DLP CinemaTM DMD digital micromirror device of Texas Instruments (TI).

　

DP50 1.3K digital projector

DLP technology (digital light processing) is a technology developed by Texas Instruments based on DMD. DMD (digital micromirror) is also an imaging chip developed by TI, and it is also the core component of DLP. DMD consists of many small aluminum mirrors, and each micro mirror is called a pixel. Its working principle is that after receiving the image control signal, it drives the micro mirror to deflect within 15 degrees, reflects light, and finally forms an image. Digital film projectors and high-end projectors generally adopt RGB three-chip DLP technology.

　

With the development of chip technology,The first 2K (2048× 1080.21 million pixels)The projector came out at the end of 2003, which adopted the DC2K DLP CinemaTM DMD chip of TI company, which improved the image resolution and contrast. This eliminated the projector that originally used 1.3K chip.

　

DP100 and DP90 2K digital projectors

In 2005-2006, DCI (Digital Cinema Advocacy Organization) released the technical specification 1.0 of digital cinema system, and various digital cinema equipment manufacturers followed suit, and developed and produced projector products conforming to DCI technical specification. According to DCI standard, the pixels of digital cinema projectors should reach 2K or 4K. Projector manufacturer including DLP technology, Barco, CTV and NEC, as well as Sony adopt liquid crystal on silicon SXRD technology, have launched a series of products.

　

In 2009, TI released its second generation DLP digital film platform.DLP Cinema?　Series II (SII or Series 2 for short). S II not only supports all the functions of the previous generation SI platform, but also enhances the signal processing ability of the system, and conforms to the DCI Digital Cinema System Technical Specification 1.2 in application.

　

In 2011, based on DLP Cinema? 1.38 "(inches).DMD 4K chipThe resolution reached 4K (4096× 2160,825 million pixels). In addition, in order to meet the needs of more small screens, the advent of 0.69 "DMD2K chips based on DLP Cinema has led manufacturers to launch DLP large projectors and small projectors based on these chips. With the advent of DLP4K projector, digital projection is comparable to 35mm film projection in definition, and the overall projection visual effect is better.

　

2019 4K global blockbuster "Maleficent: Mistress of Evil"

In 2013, TI (Texas Instruments) DLP Products Division launched a new breakthrough pixel architecture for its leading DLP Pico? technology.TIlt Roll Pixel（TRP）. The main advantages of products based on the new TRP pixel architecture include:

Improve brightness by up to 30% and higher efficiency; Energy saving by reducing power consumption by up to 50%; Twice the resolution of chips of the same size, and so on. For example, the s4 series of Barco’s fourth-generation projector is the latest series of digital projector products that take the lead in adopting 3×0.98” DC4K TRP chip, which can save more energy and further improve the degree of integration.

Progress in architecture and automation

The innovation of digital projection technology makes the control of equipment more and more automatic and intelligent.

　

Due to high integration and strong sealing performance,Heat dissipation and dust preventionIt is the most difficult problem of projectors in the past. In the past, when solving these two problems, the projectionist was particularly required to maintain the projection equipment in peacetime, but with the upgrade of the projector, the handling of these two aspects has now become simpler and more convenient.

　

The heat dissipation of the projector mainly surrounds the light source, chip and circuit. These places are easy to accelerate aging or damage if the heat dissipation is not in place, and attention should be paid not to have any dust when cooling. For example, high-precision core components such as chips cannot be polluted by any dust.

　

Now there are several ways to cool the projector:Air cooling, liquid cooling, and semiconductor cooling.. Air cooling mainly depends on the cooling channel designed in the projector; Liquid cooling is mainly aimed at the internal heat dissipation of the engine, and there is a set of liquid cooling heat dissipation system composed of liquid tank, pressure pump and heat exchanger in the projector. Semiconductor cooling, like using "Peltier" thermoelectric semiconductor refrigeration device.

　

Barco s4 projector series inherits the consistently efficient integrated cooling system of liquid cooling+air cooling+Peltier, and with the fully enclosed engine and light path design, the new double-layer HEPA washable filter screen can achieve the ultimate dustproof and efficient cooling effect. At the same time, the modular design of S4 series and brand-new network control and analysis software make the daily maintenance and repair of projectors easy, which greatly reduces the labor cost of daily operation and maintenance.

　

In addition to the continuous improvement of automation level, the projector architecture is also constantly optimized. From the original independent external server to the integrated media module IMB, to today’s integrated media server with higher integration.IMSsSome even integrate audio decoding module, which has higher integration and improved performance.

　

For example, in March, 2014, Barco first launched a product equipped with Lingrui.ICMP(Integrated Cinema Media Processor integrated media module) integrated projector of server. The ICMP module of Barco Lingrui skillfully integrates the digital movie image signal processor (ICP) with the media server responsible for the decoding function of DCI movie programs, which improves the simplicity and reliability of the projector. Intelligent projectors equipped with Lingrui ICMP can even detect potential operational errors and warn users when potential failures occur.

　

ICMP server

The historical origin of digital projector from the initial independent external server to the integrated media module IMB to the integrated media server IMSs with higher integration now comes from the actual demand of the film industry for higher image quality, higher frame rate and higher resolution. In the technical field of projectors and media servers, this can be summarized as follows,Need to pass a higherbandwidthTo process and transmit image data. This has become the driving factor of digital projectors from independent servers to IMBs(Integrated Media Blocks) and then to IMSs (Integrated Media Server) from 2005 to 2012.

　

In addition, in recent years, digital projectors are constantly strengthening their targeting.Automatic maintenance and optimization technology of laser light source and automatic image optimization technologyWith the passage of time, the white balance of the three-color laser light source of the projector is guaranteed and the color reproduction is better; The final imaging quality of the optical engine has been kept at a good level for a long time.

Progress in technical indicators

The technical progress of projector naturally promotes the improvement of its related technical indicators, so as to adapt to the landing of new projection technology.

　

For example, adapting to high frame rate projection, adapting to HDR (high dynamic range) image optimization, etc., requires a higher projectorBrightness, contrast, clarity and high color depth processing circuit, at the same time haveHigh frame rate projectionFunction.

　

The 1.3k machine adopts the 1.1 "/0.9" (inch) DLP CinemaTM DMD chip of TI company, with the contrast ratio of 1350: 1 and the deflection angle of DMD micromirror of 10. The final light output is about 6,000-13,000 lumens, and its light efficiency is relatively low, with the average light path light efficiency of 1-2 lumens/watt. At first, the 1.3k machine can handle Bit depth.

　

The second generation projector chip (DC2K DMD chip) comes in 1.2 "(inch) and 0.98" (inch), which were released by TI in 2003 and 2007 respectively. Compared with the 1.3 K chip, DC2K DMD chip increases the deflection angle of DMD micromirror by 12, making its contrast ratio more than 2000∶1. The light output of 2K projector can reach 30,000 lumens, and the color depth can reach 15 bits ×3. Moreover, the support for secure encryption/decryption, from supporting Cine I to supporting Cine II, meets the strict requirements of digital cinema for content security protection.

The 4K digital projector based on DLP Cinema? 1.38 "(inch) DMD chip has a brightness of 32,000 lumens and a contrast ratio of more than 2,100: 1.

　

S4 series projectors

Now the projector has a higher level of indicators. On BIRTV in 2020, Barco introduced the high-brightness RGB laser projector SP4K-40B with 40,000 lumens in the fourth-generation projector family, and introduced the RGB laser projector SP4K-55B with 52,000 lumens in CinemaS in 2021. In this fourth-generation projector family, the contrast ratio can reach 5,000: 1 like SP4K-27BHC.

　

In addition, with the improvement of light source, RGB laser projector has also improved the color range of the picture from DCI-P3 to.Rec2020, the color range is expanded by about.thirty percentFinally, due to the replacement of TI DLP technology, the fourth generation projector of Barco, which currently adopts the latest technology of TI, also has the ability to play.4K high frame rateThe ability of (high frame rate means > ＞24fps) greatly exceeds the original traditional signal format. Although there are not many such movies, the projector hardware is still ahead.

　

It can be said that the projection visual effect provided by the current digital projector has far exceeded the film projector era, providing a better viewing experience to a greater extent, and at the same time bringing higher intelligent automation to the operation, use and maintenance optimization of the cinema, making the cinema have a wider choice for different screens, different technical requirements and automatic projection, and greatly enhancing the security of film copyright!

　　The Central Economic Work Conference put forward that "efforts should be made to expand domestic demand" and "priority should be given to restoring and expanding consumption". Domestic demand is the basic driving force of China’s economic development, and expanding domestic demand is the strategic basis for building a new development pattern. Domestic demand includes consumption demand and investment demand. At present, the development pattern of domestic demand dominated by consumption in China has basically taken shape, and the key to expanding domestic demand is to expand consumer demand.

　　China’s economy has strong resilience, great potential and sufficient vitality, and there are many favorable factors for continuously expanding consumption. Compared with developed countries in Europe and America, the proportion of final consumption in GDP (consumption rate) in China still has a lot of room for improvement. China’s residents’ consumption is upgrading to "from good to good", and the consumption of upgraded goods and services is growing rapidly. Large cities and metropolitan areas play an increasingly leading role in consumption. As the level and quality of urbanization continue to improve, the functions of consumption gathering, leading and innovation in large cities and metropolitan areas will become more prominent. Technological innovation and application are becoming more and more active, which promotes the vigorous development of new formats, new models and new scenarios, and provides new means and strong impetus for expanding consumption. Changes in consumer groups create new space for consumption, and factors such as family miniaturization, single population growth and aging population promote the formation of new consumption concepts and new economic forms.

　　In the near future, expanding consumption should focus on improving expectations and boosting confidence. The key point is to effectively implement the "two unwavering", further relax the market access of private enterprises, unify regulatory rules and standards, fully support the development of difficult industries and small and micro enterprises, and create a better development environment for the private economy. We will do a good job in stabilizing growth, employment and prices, effectively prevent and resolve major risks, and enhance the confidence of the whole society in the overall recovery of economic operation and the continuous increase in employment and income.

　　In the medium and long term, expanding consumption should optimize the income distribution structure, improve the quality of employment, increase the income of urban and rural residents through multiple channels, and let residents have stable income to consume. It is necessary to improve the social security system, strengthen basic public services, and firmly grasp the basic bottom line of people’s livelihood, so that residents can dare to spend without worries. It is necessary to improve the consumption environment, innovate consumption scenarios, optimize the competition order, and let residents feel strong and willing to spend because of the excellent consumption environment. The key to effectively restore and expand consumption is to establish and improve a series of new mechanisms to expand domestic demand.

　　First, investment and consumption promote each other. Promote the effective combination and mutual stimulation of boosting consumption and expanding investment, and achieve a higher level of dynamic balance between supply and demand. Pay more attention to the domestic market and people’s livelihood, improve the investment structure, improve investment efficiency, and further play the role of investment in promoting consumption.

　　The second is the two-way force of supply and demand. On the supply side, we will promote the formation of a multi-level and diversified supply system, expand the opening of the service industry to the outside world in an orderly manner, and continuously improve the quality and structure of goods and services supply. On the demand side, conform to the trend of consumption upgrading, better meet the ever-changing and iterative consumption demand, and effectively release the consumption potential of goods and services.

　　Third, innovation leads the way. Innovate the concept and method of supervision, improve the efficiency of supervision, promote the sustained and healthy development of platform economy and promote the recovery of consumption. Give full play to the important role of new technologies, new models and new formats in expanding consumption, strengthen the leading function of consumption innovation in central cities and metropolitan areas, and constantly form new growth points of consumption.

　　The fourth is green and low-carbon transformation. Balance the relationship between expanding consumption and the carrying capacity of resources and environment, advocate a simple and moderate, green and low-carbon, civilized and healthy lifestyle, and promote the transformation of consumption to a healthier and moderate, green and low-carbon and more sustainable direction.

　　In terms of expanding consumption policies, we must adhere to the trend and classify policies to further enhance pertinence.

　　First, improve the fiscal and financial policies to promote consumption. Give full play to the role of fiscal and financial policies in improving residents’ consumption enthusiasm and ability, and further improve policies such as special additional deduction of personal income tax, issuance of consumer vouchers, and reasonable increase of consumer credit to promote consumption.

　　Second, speed up the upgrading and expansion of housing and transportation consumption. Effectively prevent and resolve risks in the real estate sector, continuously improve the level of public services and social security, and support rigid and improved housing demand. We will introduce preferential policies for vehicle purchase tax with the focus on encouraging renewal and replacement, and achieve accurate policy relay.

　　Third, promote the rapid recovery of service consumption. Seize the important holidays and other nodes to promote consumption, encourage local festivals with various themes and characteristics, and dig deep into the consumption potential of night economy, single economy, silver-haired economy and experience economy.

　　Fourth, optimize new consumption scenarios and consumption supporting systems. Promote the transformation and upgrading of business districts and pedestrian streets in central cities, and increase the supply of integrated experiential consumption scenarios. Improve rural logistics distribution, transportation and communication, service marketing, charging and refueling and other supporting systems to stimulate the vitality of the rural consumer market.

　　　　　　 CCTV News:Yesterday (July 29th), experts and scholars of paleontology at home and abroad announced in Nan ‘an, Fujian that the dinosaur footprint discovered in Ganzhou, Jiangxi a few months ago was the first discovery of Tyrannosaurus rex footprint in China and even in Asia.

　　　　　　 Tyrannosaurus rex, also known as Tyrannosaurus rex, is a super-large carnivorous dinosaur, belonging to theropod. A typical Tyrannosaurus Rex is 12.8 meters long, 5.5 meters high and weighs about 6.8 tons. It has a strong cervical vertebra, weak forelimbs and well-developed hind limbs and tail. They lived in the last 3 million years of the Late Cretaceous about 68.5 million to 65.5 million years ago. Then, in Cretaceous — — Disappeared in the Paleogene extinction event.

　　　　　　 Xing Lida, an associate professor at China Geo University, said: "It is a kind of animal that lives at the top of the whole dinosaur food chain. By the end of Cretaceous, we found that Tyrannosaurus rex itself and its relatives, even skeleton fossils, were very rare. In the whole of China, the dinosaur footprints of Tyrannosaurus rex were definitely not found, so this time it was a very accidental opportunity. "

　　　　　　 According to experts, a few months ago, a construction team in Ganzhou, Jiangxi Province, found a huge red sandstone with a strange mark on it while repairing roads. After expert appraisal, it was found that this was the footprint of a Tyrannosaurus Rex.

　　　　　　 Xing Lida: "This is its middle toe, and this is its toes on both sides, very strong second toe, third toe and fourth toe. The existence of this bulge means that we can classify it as a carnivorous dinosaur. Other features include that its toenails are very sharp, and its heels are very round and the overall width is very wide, which means that this dinosaur has evolved many features to increase its grip. "

　　　　　　 At present, this Tyrannosaurus Rex footprint fossil is in the Yingliang Stone Natural History Museum in Nan ‘an, Fujian. According to the staff of the museum, next, this fossil will be exhibited with other kinds of footprint fossils.

　　　　　　 Liu Liang, curator of Yingliang Stone Natural History Museum, said: "Stone, as a true recorder from the formation of the earth to the emergence of human beings to modern civilization, plays a very obvious role in this process, which is why we focus on the field of fossils and constantly explore some new major discoveries."

　　Next, please first ask Mr. Dong Haili to introduce the relevant situation of promoting the construction of "Design Henan" in our province.

　　Dong Haili, Party Member and Deputy Director of the Provincial Department of Housing and Urban-Rural Development

　　Dear media friends:

　　Thank you for your long-term concern and support for housing and urban and rural construction in the province! The international competition of urban design and creative architecture held in this airport area is another concrete action to implement the strategic decision of "designing Henan" after the first international forum of "designing Henan as an aviation city and a global hub" was held in Zhengzhou Airport in March. I believe that the holding of this activity will definitely promote the economic and social development of the airport area. Taking this opportunity, I would like to introduce the relevant situation of promoting the construction of "Design Henan" in terms of doing a good job in urban and architectural design in the whole province.

　　The provincial party committee and government attached great importance to the work of "designing Henan", and Lou Yangsheng, secretary of the provincial party committee, personally arranged, deployed and listened to the work of "designing Henan". The provincial government has successively issued the Action Plan for Designing Henan Construction (2022-2025), the Medium-and Long-term Planning for Designing Henan Construction (2022-2035) and Several Policies and Measures for Supporting the High-quality Development of Design Industry in Henan Province. It is emphasized that urban modernization should be led by urban and architectural design, highlighting cultural heritage, distinctive features, green livability, wisdom and toughness. In order to implement the construction requirements of "Designing Henan" by the provincial party committee and the provincial government, the "Three-year Action Plan for Improving Urban and Architectural Design (2023-2025)" was issued around the overall requirements of "Improving Urban and Architectural Design", and it was proposed that through the implementation of the three-year action, the business environment of urban and architectural design industries in our province was continuously optimized, the industry scale was steadily increased, the creative level was continuously improved, and the core competitiveness was significantly enhanced.

　　First, implement beautiful urban design. First, we must strictly implement the "Implementation Opinions of the General Office of the People’s Government of Henan Province on Strengthening the Management of Urban and Architectural Styles", strengthen the style shaping of key areas and important buildings, coordinate the shape, color, volume and height of important buildings from the overall plane and three-dimensional space, and strengthen the control and guidance of urban skyline and public space. We must not only put an end to architectural chaos such as "greedy for foreign things and seeking strange things", but also avoid the phenomenon of "one city with one face and ten thousand buildings with one face". Second, we should fully implement the overall urban design, strengthen the design of urban center, main streets and important squares, integrate the most representative and identifiable cultural elements, and create landmark buildings with local cultural characteristics. Take landscape as an important component of urban design, strengthen urban ecological construction and restoration, prevent high-intensity construction, avoid "blind alley" development, leave enough open space, green space and public service facilities construction land, and build a beautiful urban spatial pattern of "patchwork, density, dew, ventilation and ventilation". Third, we should improve the design level of smart cities, strengthen the design and application of urban information models in urban construction and management, implement the intelligent transformation of municipal infrastructure, implement the unified management of urban operation, and implement the safety concept in the whole process of urban planning, construction and management.

　　Second, do a good job in architectural engineering design. First, we must implement the architectural policy of "applicability, economy, green and beauty" in the new period, design in strict accordance with laws and regulations and mandatory standards for engineering construction, and seriously investigate and deal with illegal and illegal survey and design behaviors that violate mandatory provisions. Second, we should inherit the excellent Central Plains culture in design and creation. Architects are required to deeply study the excellent history and culture of the Central Plains, the Yellow River culture and the regional culture, make bold innovations in engineering construction and urban renewal practice, form diversified local architectural styles, and promote the inheritance and innovation of excellent traditional architectural culture. Actively encourage technical forces to participate in rural construction, protect rural culture and village texture, and constantly improve the level of rural housing design and rural construction. Third, we should prosper design creation, carry out architectural criticism and architectural design research, promote the integration and sublimation of architectural design concepts, and constantly improve the original level of scheme design. Fourth, we should focus on providing good houses and communities for the people and improve the housing construction standards and design level. Promote green building design, optimize the spatial layout of residential areas, reasonably determine the upper limit of plot ratio and the lower limit of green space ratio of residential areas, and rationally allocate indoor and outdoor public activity spaces and venues for the elderly and children.

　　Third, strengthen the survey and design industry. First, we must promote the transformation and upgrading of enterprises. Support the integrated development of large enterprises, extend the industrial chain through joint operations, mergers and acquisitions, etc., carry out whole-process engineering consulting, and support qualified large-scale backbone enterprises to go public for financing; At the same time, small and medium-sized enterprises are encouraged to take the development path of "specialization and novelty" and cultivate a group of enterprises with strong industrial design strength in green buildings, ultra-low energy-consumption buildings, prefabricated buildings, urban landscape, municipal infrastructure construction, building intelligence and other special designs. Second, we must strengthen the introduction of talents. Encourage enterprises to introduce a number of high-end talents from inside and outside the province, strive to introduce academicians of the two academies and national survey and design masters, and set up academician workstations and master studios. We will also provide convenient services such as housing security and provident fund loans to those who meet the relevant talent identification standards, so that all kinds of talents can come in and stay. Actively develop the cultivation of young design talents. Third, we should focus on the activity of "one division, one competition, one evaluation and one project". The first division is to identify the "master of construction engineering survey and design in Henan Province", play a benchmarking and guiding role, and let outstanding talents stand out. The first competition is to hold the first "Good House in Henan" design competition. Mobilize the vast number of designers to focus on the overall goal of people’s satisfaction and produce more masterpieces. The first appraisal is to hold the selection of the most beautiful buildings and blocks. One topic is to carry out the research on the characteristics of traditional folk houses in Henan Province.

　　Fourth, optimize the market environment. The first is to strengthen industry supervision. Seriously investigate and deal with collusive bidding, subcontracting, linking, illegal subcontracting, lending qualification certificates, separation of witnesses and certificates, crack down on the phenomenon of setting discriminatory bidding terms according to law, and strive to create an open, fair and just market environment. The second is to improve the credit evaluation system of survey and design industry. Implement the application of credit evaluation results in project approval, bidding, evaluation and awards, and list the survey and design enterprises with excellent credit evaluation grades in the white list, and implement inspection exemption in the dynamic assessment of qualifications. The third is to encourage and guide the survey and design enterprises in our province and outstanding enterprises at home and abroad to jointly participate in major planning, major projects and major engineering design services inside and outside the province, so as to cultivate qualifications, expand strength and shape brands in actual combat. At the same time, we will also formulate incentive policies to reward enterprises that have made outstanding contributions to economic development and made outstanding achievements in industry development.

　　In the next step, in accordance with the work arrangements of the provincial party committee and the provincial government, we will work with relevant departments to solidly promote the design of Henan construction, fully support the urban construction and development of the airport area, and help design the high-quality development of Henan. thank you

　　Ping Ping, Deputy Director of Propaganda Department of Provincial Party Committee and Director of Information Office of Provincial Government

　　thank you Next, please ask Mr. Guo Peng to introduce the urban design and creative architecture international competition of Zhengzhou Airport 2023.

　　Guo Peng, member of the Party Working Committee and deputy director of the Administrative Committee of the Airport Area.

　　Dear media friends:

　　I am very glad to meet you in the press conference hall of the provincial people’s government and exchange views on the upcoming 2023 "Silk Road in the Air" international competition for urban design and creative architecture in Zhengzhou Airport, Henan Province.

　　The organizer of this international competition is Zhengzhou Airport, Henan Province, and it is also the well-known Zhengzhou Airport Economic Comprehensive Experimental Zone. The airport area covers an area of 747 square kilometers and is located in the golden triangle of Zhengzhou, Kaifeng and Xuchang. In 2013, the State Council was approved as the only aviation economic experimental zone in China. Since 2022, the provincial party committee and government have systematically reshaped and reconstructed the airport area. The five new strategic orientations of the airport are: the pilot area of "Aerial Silk Road", the National Airport Economic Experimental Zone, the Central Plains Economic Zone and the core growth pole of Zhengzhou Metropolitan Area, the modern and internationalized world-class logistics hub, and the Central Plains Special Zone; The five centers under construction are: international advanced manufacturing center, international trade center, international transportation and logistics center, international creative fashion center and international innovative talent center. The airport has become the growth pole of Zhengzhou’s development with great strategic value and the bull’s nose of Henan’s opening to the outside world.

　　In the next ten years, Zhengzhou Airport will be a new golden decade for its "second venture". On the basis of fully drawing lessons from the latest concept of Professor John Casada, the chief consultant of the airport area and the first person in the global aviation economy-international aviation metropolis version 4.0, we have extensively drawn opinions from all walks of life and planning experts at home and abroad, and divided the 747-square-kilometer airport core area into four major areas: southeast, southwest, central and north. According to the international functional division, we have determined that it includes "the window of the Central Plains, the aviation hub port, the Central Plains Medical Science City and the future"

　　The new golden decade airport can not be separated from planning and architectural design. High-quality planning and design is the premise of high-quality development and the "first button" of urban development. High-quality architecture is the art of urban mobility, and it is also the core competitiveness of a city to avoid a thousand cities and establish its image and brand.

　　In order to further implement the "Design Henan" strategy of the Henan Provincial Party Committee and the provincial government, promote the leap-forward development of the airport new golden decade with a forward-looking view of 30 years and the world, and open up an institutional channel for the world’s top planning, design, architecture and aesthetics talents to serve Henan’s development, we have planned the 2023 "Silk Road in the Air" urban design and creative building international competition of Zhengzhou Airport in Henan. After intense preparations, it was officially released to the world today.

　　This international competition is divided into three parts, one is the optimization and upgrading of the overall urban design of the whole region (focusing on 21 cities) and the urban design of the future city. Among them, the overall urban design optimization and upgrading (focusing on 21 cities) is within the jurisdiction of Zhengzhou Airport, covering an area of about 747 square kilometers. The urban design scope of the future city is: Chaohu Road in the north, Jiude South Street in the east, Yan Dou Avenue in the south and Hedong Road in the west. The second is the urban design of Zhongyuan Medical Science City, which covers Bohai Road in the north, Sunwu Road in the east, Nanhai Avenue in the south and Beijing-Hong Kong-Macao Expressway in the west. Thirdly, the conceptual design and deepening of the international cultural exchange center of Zhengzhou Airport Garden Expo Park. The site is located in the Garden Expo Park International Eco-city, covering an area of about 20 mu and a building area of 15,000 square meters. The purpose of this creative architecture competition is to attract new ideas from all over the world and provide opportunities and platforms for young and middle-aged new architects to participate in the construction and development of the port area. The three parts of the competition are released as a whole and promoted separately, and are coordinated by the airport management Committee.

　　In order to attract global planning and architectural design teams to participate in the development and construction of the port area, there is no qualification requirement for this competition, and global open registration is adopted. Design institutions and consortia at home and abroad can sign up for the competition, and individuals or combinations of individuals are not accepted. The contest adopts two registration methods: "Intention invitation+open solicitation". It is divided into two stages: "prequalification" and "scheme design and review". The first is the pre-qualification stage. Public announcement, domestic and foreign professional design institutions submit corresponding registration documents and concept proposals, and we will organize a pre-qualification meeting to select the finalists and enter the next stage together with the invited units. The second is the scheme design and review stage. After the short-listed design institutions submit the results documents that meet the requirements within the specified time, we organize a scheme review meeting and select the final winning scheme from the short-listed design schemes.

　　The 2023 "Silk Road in the Air" International Competition for Urban Design and Creative Architecture in Zhengzhou Airport, Henan Province will officially launch the pre-release and forecast name today. In July, the official announcement and the first-stage design task book will be released in three competition parts. In August, the prequalification results and the second-stage design task book will be released, and in October, the final evaluation results of the scheme will be announced in three competition parts. In order to cultivate and support the local planning and design forces in Henan and further enhance the influence of "designing Henan", the local planning and design team will be invited to participate in the whole process of this international competition for urban design and creative architecture, and the final achievement integration will be completed by the team that won the first place in the competition and the local planning team in Henan.

　　Dear media friends and comrades, this international competition for urban design and creative architecture of the airport is another international competition in Henan after the international bidding for the master plan of Zhengdong New District in 2001, after a lapse of 22 years. At that time, Zhengdong New District was also well-known at home and abroad because of international competitions. All parties praised Zhengdong New District as a "plan from the perspective of the world", and the international bidding scheme of the city at that time was "the crowning touch of new urban construction". Later, the image of Zhengdong New District as an international city became increasingly prominent, and the international bidding for planning in 2001 contributed greatly. After ten years of accumulation, the airport area also has the conditions to continue the internationalization strategy of Zhengdong New District and take off in an all-round way. Focusing on the goals of "designing Henan", "China’s aviation metropolis" and "a world-class model of the integration of production and city", the airport will hold an international competition on urban design and creative architecture every year, which will continuously transport design talents from all over the world for the high-quality development of Henan. This institutionalized arrangement of the airport will surely enhance the international reputation of Zhengzhou, Henan and even the whole inland area, let "Design Henan" go to the world, and let Zhengzhou Airport, the "Silk Road in the Air and Hub in the World", go to the world.

　　In order to run this international competition well at a high level, the whole region attaches great importance to it, and all units at all levels have carefully organized and deployed it, and have devoted a lot of energy and painstaking efforts. Here, I would like to express my respect and condolences to the comrades who organized the international competition. The high-quality development of Zhengzhou Airport in Henan Province is also inseparable from the concern and support of the news media. The new golden decade needs the full help and promotion of friends from the news media. Here, on behalf of the Party Working Committee and Management Committee of the Airport Area, I would like to express my heartfelt thanks to you! I urge you to actively participate in this international competition and follow up the whole process to witness an important step of internationalization, fashion and aesthetics of Zhengzhou Airport in Henan Province. thank you

　　Recently, Henan will rebuild the Provincial Academy of Medical Sciences, accelerate the creation of an innovative pattern of "one hospital, one city and one industrial cluster", and lay it out in the airport area. Excuse me, what advantages does the port have in medical research and industrial ecology? Next, how will the port serve the construction of the Provincial Academy of Medical Sciences? Thank you.

　　Qin Xindong, Director of the Headquarters Office of Zhongyuan Medical Science City in the Airport Area

　　Thank you for your question. Recently, the provincial party committee and the provincial government proposed to rebuild the Provincial Academy of Medical Sciences, which will be located in the airport area, and at the same time, build the Central Plains Medical Science City and the biomedical health industrial cluster. The construction of "one hospital, one city and one industrial cluster" is an extremely rare development opportunity for the airport area. The planning area of "one hospital, one city and one industrial cluster" is about 40 square kilometers, which is located in Shuanghe Lake area of Zhengzhou Airport in Henan Province. The airport area has the following advantages in medical research and industrial ecology:

　　First, the industrial base is good. Seven service platforms have been built, including new drug screening and testing platform, drug evaluation platform (animal house), macromolecular drug CDMO platform, small molecule API& preparation CDMO platform, gene therapy CDMO platform, cell therapy CDMO platform and clinical CRO service platform. We have also built some pharmaceutical enterprises such as Zhengzhou Linkong Biomedical Industrial Park (Chuangtai Bio) and Zhengzhou Demai Pharmaceutical Industrial Park (Antu Bio).

　　Second, the traffic conditions are convenient, with Beijing-Hong Kong-Macao Expressway and Shangdeng Expressway on the west and north respectively. It is about 45 kilometers away from the provincial government and Zhengzhou International Convention and Exhibition Center, 40 kilometers from Zhengzhou East Station, 12 kilometers from Xinzheng Airport and 10 kilometers from Zhengzhou Airport Station.

　　Third, the facilities are complete. Foreign language senior middle schools, 130 and 131 middle schools, art primary schools, science and technology street primary schools and a number of kindergartens have been built, and provincial talent apartments and other infrastructure have been equipped. Two 220kv and three 110kv substations, sewage treatment plants and other facilities have been built.

　　For the next step, how to implement the major decision of the provincial party Committee and government to rebuild the Provincial Academy of Medical Sciences through the Central Plains Medical Science City, our airport area mainly starts from the following aspects. First, around the goal of "one hospital, one city, one industrial cluster", act quickly, start international competition bidding, and prepare high-level planning and related special programs for the integrated development of Provincial Academy of Medical Sciences and Zhongyuan Medical Science City. Carry out special research, implement the operation mode of "Management Committee+Company", and accelerate the local transformation of the Provincial Academy of Medical Sciences and the preparations for the headquarters of the Provincial Academy of Medical Sciences and the Provincial Ophthalmology Research Institute. Adhere to the principle of "one-time planning and phased construction", speed up the improvement of supporting services of Zhongyuan Medical Science and Technology City, create "urban functional units" conducive to the introduction of innovative resources, meet various needs such as "food, housing, travel, entertainment, education and medical insurance", create a "new urban commercial space" in Zhongyuan Medical Science City, vigorously promote the planning and construction of supporting facilities for commercial services, and actively provide quality service guarantee. Second, in terms of commercial facilities, we started the planning and construction of 12 mu of commercial facilities around the Provincial Academy of Medical Sciences, started the development and construction of 10 mu of commercial service land around Shuanghe Lake, increased the attraction and service of star-rated hotels, high-end restaurants and large-scale commercial complexes, and strived to build a commercial comprehensive block integrating catering, entertainment and leisure. Third, in terms of supporting education, the construction of Shuanghe Lake First Street Primary School will be started, and primary and secondary schools such as Provincial Experiment and Zhengzhou Foreign Language will be launched in the airport area. In terms of supporting public transportation, bus and subway lines will be opened.Guarantee the staff of the Provincial Academy of Medical Sciences to settle in and commute daily. Fourth, in the aspect of talent room security, about 7,000 talent apartments have been built to meet the needs of the Provincial Academy of Medical Sciences and the first batch of apartments, and the second phase of talent room has been built nearby, trying to bring convenient, high-end and fashionable supporting services to the living talents.

　　In the future, Zhongyuan Medical Science City will coexist with the Provincial Academy of Medical Sciences, and will establish a supporting system of high-quality comprehensive services to create a scientific home that is livable, suitable for industry, suitable for research and innovation. thank you

CT showed that Ms. Li’s thumb was injured.

　　On November 23, Ms. Li, who lives in Jilin City, Jilin Province, turned to the cover news cloud for help. On November 20, when she used the "Flower Pig Taxi" (hereinafter referred to as Flower Pig) network car platform to take a taxi, her right thumb fingernail fell off because of the driver’s operation error. Three days have passed, but no one has come out to take responsibility.

　　"I have spent more than 2000 yuan to see a doctor. Looking for a driver for this matter, the driver ignored me; Looking for a platform, the platform said they had no choice; Call the police. The police said it was a civil dispute. I really don’t know what to do. " Ms. Li said.

　　The driver stepped on the accelerator.

　　The passenger suffered a heart-rending pain.

　　Ms. Li introduced that on the evening of November 20th, she and her boyfriend took a taxi from Songhua River New Town in Jilin City to the west gate of Yulong Bay. After arriving at the destination, she got off with her boyfriend. However, when they had not completely closed the door, the driver had already started the car and left. "He should be in a hurry to catch the next order, because when he was about one kilometer away from the destination, the driver ended our order ahead of schedule, saying that he would take the next order in advance."

　　Ms. Li said that she felt heartbreaking pain at the moment when the car left. "At that time, the thumb of my right hand was caught by the door, and his speed was relatively fast, which caused the nail cover of my thumb to be torn off." Ms. Li said that at that time, her fingers were bloody, and she squatted on the ground in pain, and the driver didn’t know whether he didn’t find it or deliberately ignored it, so he drove away.

　　Nobody takes responsibility.

　　Civil disputes cannot be filed by the police.

　　Later, Ms. Li and her boyfriend called their friends who lived nearby and asked them to drive them to the hospital. When I arrived at the hospital, I found that Ms. Li had an open fracture of her thumb and had to undergo surgery. "I thought it was just an ordinary trauma, but I didn’t know it was bad until I heard the operation. In order to save the cost of surgery, I changed three hospitals in a row before I found a slightly cheaper one. "

　　After the operation, Ms. Li found the driver at that time. The other party said that if she had the responsibility, she hoped that Ms. Li would find herself through the police. After Ms. Li called the police, the police told her that the matter was a civil dispute and could not be filed. In desperation, Ms. Li had to pin her hopes on the car platform of Hua Xiaozhu. "At that time, I thought that the car was found from them and they should manage it." However, I didn’t expect that the flower pig platform said that the platform and the driver only belong to the cooperative relationship, and I hope that Ms. Li will take legal procedures to solve the problem.

　　Ms. Li said that she learned about the car platform of Flower Pig Network from a friend a few days ago, and only used it five or six times until the day of the accident. "At that time, I heard that the after-sales customer service here was not very good, but I thought it was cheap, so I didn’t think so much. I didn’t expect it to be so troublesome after the accident." Ms. Li said that at present, she hopes that the car platform of Flower Pig Network can give herself a statement, "I have been playing the piano since I was a child, and now this problem has arisen. I don’t know if I can still play the piano."

　　Flower pig platform response

　　Customer service has been involved in this matter.

　　On the afternoon of November 23, Huaxi Dushi Bao and the cover journalist contacted the Flower Pig Platform. The other party said that there is a special customer service involved in this matter, which is not what Ms. Li said. "We also contacted the driver. The driver also said that if the investigation is clear that it is indeed his responsibility, he is willing to take responsibility. I hope Ms. Li can give us some time to investigate. "

　　The other party also said, "We have made preliminary communication with passengers and drivers, and we will tell passengers about the follow-up treatment and progress at the first time."

Characteristics of related risks and specific preventive measures

Novel coronavirus infection

Novel coronavirus is mainly transmitted by respiratory droplets and close contact, but it can be transmitted by aerosol in a closed environment, and contact with articles contaminated by virus can also cause infection. The elderly and immunocompromised people are at higher risk of serious illness after infection.

Main preventive measures:

(1) Open the window regularly for ventilation to keep indoor air circulation.

(2) Try to avoid close contact with people with symptoms of respiratory infection and wear masks scientifically.

whooping cough

Pertussis is mainly transmitted by respiratory droplets, such as coughing and sneezing of infected people, which spread bacteria into the air. Susceptible people are infected by inhaling droplets with bacteria. It can also spread through close contact. Parents or other residents infected with whooping cough are the main sources of infection for infants.

Main preventive measures:

(1) School-age children should be vaccinated as early as possible and throughout the whole process.

(2) Infants with persistent cough or shortness of breath, hypoxia, vomiting and other symptoms, especially when family members have cough symptoms, should seek medical advice in time.
