Sichuan Linshui launched a new round of global nucleic acid detection.

  On May 16th, the reporter learned from the press conference of COVID-19 epidemic prevention and control in Guang ‘an City, Sichuan Province that, in order to ensure social zero clearing in the shortest time and block the virus transmission chain, nucleic acid testing will be carried out in Linshui County for three consecutive days from May 16th.

  It is reported that since May 9th, Guang ‘an has reported a total of 34 local confirmed cases and 467 local asymptomatic infections (463 cases in Linshui County). May 15th 0— At 24: 00, Guang ‘an reported 14 new confirmed cases and 69 new asymptomatic infections (67 cases in Linshui County).

  It is understood that on 15th, Guang ‘an City dispatched medical personnel, party member cadres, militiamen and volunteers from the whole city to help neighboring waters, and strived to achieve social clearing in the shortest time.

  Luo Ronghong, the second researcher of Guang ‘an Health and Wellness Committee, introduced that the new round of global full-scale nucleic acid testing in Linshui County was divided into 26 districts, 681 sampling points and 2,159 sampling stations. By 15: 00 on the 16th, 495,143 nucleic acid samples had been collected on the first day except for the sealed control area and the control area.

  At present, in accordance with the principle of "stopping classes and teaching", more than 380,000 primary and secondary school students in Guang ‘an have switched to online teaching except the third grade. (Reporter Chen Di, Dong Xiaohong)

  One Hundred Years of Solitude Penguin Edition

  Not long ago, the topic of whether "Four Great Classical Novels" is suitable for teenagers’ reading triggered a social discussion. In fact, the discussion about famous books has a long history. A question that cannot be avoided in many discussions is: What kind of works can be called masterpieces? On this issue, this newspaper interviewed many experts.

  The readership is relatively large.

  I felt it when I was drinking: "till, raising my cup, I asked the bright moon, to bring me my shadow and make us three"; Being in a foreign land can’t help feeling: "lifting myself to look, I found that it was moonlight, sinking back again, I thought suddenly of home"; Even if you are not a literature lover, you may blurt out the classic dialogue in Shakespeare’s Hamlet, "To be or not to be, that is the question".

  These works have become recognized masterpieces by virtue of their huge readership. Mortimer J. Ejdero, an American educator, pointed out in How to Read a Book that masterpieces have the largest number of readers, and masterpieces have accumulated a large number of readers by time.

  Take "Four Great Classical Novels" as an example, they have a high degree of popularity and a large readership. According to a set of data recently released by China Edition Library, according to CIP statistics from 2013 to August 2016, the top 10 repeated publications are masterpieces. Among them, 525 were published in The Journey to the West, 492 in A Dream of Red Mansions, 485 in Water Margin and 484 in Romance of the Three Kingdoms.

  Take Lu Yao’s novel "Ordinary World" as an example. According to the data of the publishing house, by September 2015, "Ordinary World" had sold at least 3 million sets.

  Enlightening influence

  "Whether a literary work can be called a masterpiece depends on whether it truly reflects social reality and social problems, and whether people can observe society and history from literary works and then think about it." Dang Shengyuan, secretary of the Party Committee of the Institute of Foreign Literature of China Academy of Social Sciences, told this newspaper that if a book is to become a masterpiece, it should be original and reach a certain ideological depth, thus inspiring readers to think.

  Mortimer J. Ejdero also believes that masterpieces are the most influential, because they are the most enlightening and instructive, and contain unique insights, which are what predecessors have not said and what predecessors have not said.

  One Hundred Years of Solitude by Colombian writer Garcí a Má rquez gives many inspirations in literary creation. Mo Yan, a China writer, admits that his literary creation was inspired by Marquez’s magical realism in Latin America. And Marquez himself admitted that his creation was also inspired by Kafka’s Metamorphosis.

  Cheng Guangwei, a professor at the College of Literature of Renmin University of China, told this newspaper that literary masterpieces can be divided into literary classics and literary history classics; The former has a long artistic vitality, while the latter may be slightly less artistic, but it has great influence in the history of literature, especially in the historical turning point. For example, Liu Xinwu’s novel The Head Teacher, published in 1977, is the first of its kind and has great influence.

  Of course, masterpieces don’t refer exclusively to literary works. Dang Shengyuan said that if other theoretical and research works want to become masterpieces, they should be able to promote the development of their disciplines with ideological and originality.

  There is continuity in time

  "Although different readers and readers in different periods have different criteria for judging masterpieces, masterpieces should have something in common. Mo Yan’s works and Jia Pingwa’s works are still being studied. After twenty or thirty years, these works are still not out of date. " Cheng Guangwei said.

  Famous works often have continuity in time, and many works have been circulated for decades, hundreds or even thousands of years.

  The Art of War was written about 2,500 years ago. Zhong Shaoyi, a researcher at the Academy of Military Sciences, believes that some basic orientations of Sun Tzu’s strategic thinking, such as "emphasizing fundamentals", "being prepared for everything" and "striving for total victory", are of reference value for properly coping with the long-term complex situation of national security. Bernabe, president of Italian Eni Company, commented on Sun Tzu’s Art of War, saying that it is a comprehensive textbook on strategy and can still be applied to various human activities today.

    Dang Shengyuan said that the development process of a discipline and a research field is composed of one masterpiece and one masterpiece. China’s literary history of thousands of years is so rich and splendid because there are high-level masterpieces in every stage and era. "Although the achievements of masterpieces in art and thought belong to its birth period, masterpieces may also transcend history and time and space, and can still give people new inspiration and be continuously interpreted after thousands of years of birth. The bestseller is different, and it is likely to disappear after a while. "

  When it comes to bestsellers, Dang Shengyuan thinks that there are differences between bestsellers and masterpieces in terms of whether the readers are broad or not. Dang Shengyuan said that bestsellers can accumulate a lot of readers in a period of time, while masterpieces are likely not to sell well in a certain period of time.

  Ejdero also mentioned this point in How to Read a Book. He believed that readers of famous books gathered through time, not for a while, and that famous books were not bestsellers within a year or two, but enduring.

  Dang Shengyuan believes that, unlike bestsellers, masterpieces may not be paid attention to during their birth, and it will take some time for them to be rediscovered and interpreted. Tao Yuanming’s landscape poems in the Eastern Jin Dynasty were rediscovered only after the rise of landscape poems by Wang Wei and Meng Haoran in the Tang Dynasty. (Li Zeyan Pan Xutao)

National CDC: When centralized or isolated at home, it is not allowed to lock the door outside.

  On the afternoon of September 29th, the State Council Joint Prevention and Control Mechanism held a press conference to introduce the situation of epidemic prevention and control during the National Day and answer questions from the media.

  Lei Zheng Long, director of the Department of Communication and Prevention of the National Bureau for Disease Control and Prevention, said that since the outbreak of COVID-19, we have always adhered to the principle of "people first, life first", guiding all localities to conscientiously implement the requirements of relevant prevention and control policies and measures, do a good job in accurate prevention and control, strengthen the prevention of safety risks, and earnestly safeguard the life safety and health of the broad masses of the people.

  One is in nucleic acid detection. All localities are required to reasonably organize and arrange nucleic acid inspection for the masses to avoid gathering and chatting. When people take part in nucleic acid testing, they should pay attention to personal protection, keep a straight line, wear masks and do good hand hygiene. All localities should also make reasonable arrangements for sample transfer vehicles, which should not be used for other purposes during the transfer task.

  The second is in the process of flow adjustment and transshipment. It is required that all localities should strengthen on-site face-to-face flow adjustment, and the flow adjustment personnel should also do personal protection, and scientifically and accurately determine the risk personnel such as close contacts, close contacts, and exposed personnel in epidemic-related places. Make overall arrangements for the deployment of transshipment, formulate a transshipment plan in combination with local actual conditions, reasonably arrange transshipment tasks and transshipment time, strengthen the daily inspection and safety maintenance of transshipment vehicles, improve the safety awareness of drivers and passengers, put an end to drivers’ fatigue driving and ensure transshipment safety.

  The third is in the centralized isolation link. The infrastructure of centralized isolation places should meet the current national standards for building safety, fire safety, earthquake prevention and disaster prevention, strictly regulate the management of isolation points, and prevent cross-infection. For special people who are not suitable for centralized isolation after evaluation, measures of home isolation can be taken. For those who are not suitable for single room isolation, appropriate personnel should be appointed to accompany them.When centralized or home isolation measures are taken, it is not allowed to lock the door outside.

  The fourth is the supply of living materials, medical care and other links. After the outbreak, all localities should scientifically and accurately define the risk areas and make dynamic adjustments, strictly implement management requirements according to regulations, and make clear that special personnel teams are responsible for the supply of basic living materials for residents, especially to prevent food safety incidents. It is necessary to designate specialized medical institutions to provide medical services for residents in high-and medium-risk areas and provide medical convenience for special people.

Memory chips arrive late in spring, but? AI ignites demand HBM "saves the field" Hynix, Samsung and other giants’ financial reports.

According to Cailian News, with the continuous injection of artificial intelligence by various capitals, the supply of high-bandwidth memory (HBM) is in short supply, and global technology giants including NVIDIA, AMD, Microsoft and Amazon are all bidding for the fifth-generation high-bandwidth memory HBM3E of SK Hynix. Recently, HBM’s "rescue" memory chip giant reported that the loss of DS department where Samsung’s electronic storage business is located narrowed in the second quarter, and SK Hynix’s sales in the second quarter exceeded analysts’ expectations. The company said that the expansion of the generative AI market has rapidly pushed up the demand for AI server memory, so the sales of high-end products such as HBM3 and DDR5 increased. Judging from the performance of the secondary market, A-share listed companies with the concept of HBM have also taken advantage of the wind. The stock prices of HBM epoxy plastic packaging supplier Huahai Chengke, HBM agent Shannon Xinchuang and HBM substrate supplier Zhongfu Circuit have increased by 157%, 158% and 136% respectively since May.

Micron Technology has previously stated that the capacity requirements for DRAM and NAND of AI servers are 8 times and 3 times that of conventional servers, respectively. Memory chips can be divided into volatile memory chips and nonvolatile memory chips according to whether data is lost after power failure. DRAM is the most common volatile memory chip, and NAND flash memory chip and NOR flash memory chip are the most common nonvolatile memory chips. According to WSTS statistics, in the memory chip market in 2021, DRAM accounts for 61%, NAND Flash accounts for 36%, and other memory chips account for only 3%.

Oriental fortune securities’s February research report pointed out that DRAM’s market head enterprises are Samsung, SK Hynix, Micron, etc., and Chinese mainland’s representative enterprises include Changxin Storage and Fujian Jinhua. The market head enterprises of NAND Flash are Samsung, Chivalrous, Western Digital, etc., and the representative enterprises of Chinese mainland are mainly Changjiang Storage; NOR Flash’s market head enterprises are Winbond, Wanghong, Zhaoyi Innovation, etc., and Chinese mainland’s representative enterprises are mainly Zhaoyi Innovation.

▌ SK Hynix, Samsung and Micron, the three leading global memory chips, pointed out that the price, supply and demand and space end blew the horn of industry recovery.

HBM is a DRAM product with the fastest data processing speed. It is a DRAM memory chip based on 3D stacking technology. After stacking multiple DDR chips, it is packaged with GPU, which can achieve higher bandwidth, higher bit width, lower power consumption and smaller size. The latest financial report shows that the performance of SK Hynix, Samsung and Micron, the three leading memory chip DRAM, began to rebound. Samsung Electronics 23Q2′ s revenue declined due to the decline in smartphone shipments, but its storage business improved compared with the previous quarter. The official said that it was mainly due to the company’s focus on HBM and DDR5 products; SK Hynix’s sales in the quarter ended June 30 were 7.31 trillion won (about 5.7 billion US dollars), down 47% year-on-year, but exceeding analysts’ expectations of 6.05 trillion won. Although HBM’s revenue in SK Hynix currently accounts for less than 1%, this proportion is expected to rise to 10% this year; Meguiar’s 23Q2 performance rebounded after three consecutive quarters of decline. In addition, the monthly performance of the original factory in Taiwan, China also improved continuously month on month.

The research report released by Pan Chang, TF Securities on July 17th pointed out that recently, the favorable turning point of memory chips has been frequently reported, and the horn of recovery seems to be in our ears. From the perspective of historical cycle, the cycle of the storage industry is about 3-4 years. This cycle starts from 2020Q1, and the price peaks in stages in 2022Q1. At present, the price has been reduced for six consecutive quarters, and it is in the bottoming stage of the cycle.

In terms of price, since Q2 this year, a number of suppliers have issued bottoming signals. First, Samsung and Micron issued a notice to dealers, no longer taking orders from DRAM and NANDFlash at low prices, and refused to accept quotations lower than those in April. In May, it was reported that Samsung Electronics and SK Hynix were considering raising their quotations after the original flash memory of Changjiang Storage officially started to increase its price by 3-5%. In late June, only Samsung was willing to conduct cSSD (Consumer Solid-State Disk) transactions in advance, and the dealers hoped that the suppliers would make concessions, but they were all rejected.

Pan Wei pointed out that on the demand side of supply, Micron announced in June that it expected to reduce production to 2024. Earlier, in 2022Q4, the original factories drastically cut their capital expenditures. If the normal production cycle is 3-4 months, the effect of supply contraction and production reduction will be accelerated in Q2 and Q3. South Asia Branch said that the company had urgent orders in some application fields. Recently, Winbond’s demand for three major applications, such as consumer electronics, television and Internet of Things, has warmed up, and industrial control-related orders have continued to be hot, and customers have rushed in, and there are also a lot of them.

In addition, on the space side, in the short term, the scale of memory chips will increase quarter by quarter, and in the long term, the storage demand under the catalysis of AI is expected to increase several times. On the geopolitical side, overseas manufacturers gradually withdrew from the niche market, and Meguiar’s incident accelerated local substitution.

▌ The memory chip will be reversed or "late" at the bottom. In the two quarters, the organization expects DRAM or NAND Flash to recover the cross-border layout of many A-share listed companies faster.

It is worth noting that at present, the memory chip industry seems to be confirming that it is about to bottom out, but the share price of 76 billion A-share leader Zhaoyi Innovation is "still calm". In fact, the impending reversal has even been "late". Recently, Yole Intelligence, a market research organization, updated a monitoring data report of the memory chip market. In Yole’s original forecast, the global memory chip market will start to recover in the second quarter of 2023, but its latest report points out that there is no need to hold too much hope for the memory chip market in the third quarter of 2023, and it is optimistic that the market will start to pick up in the fourth quarter of this year.

However, Yole is not the only one who predicts that the storage market will recover in the coming fourth quarter. According to Taiwan Province Economic Daily and Science and Technology News, citing the latest report issued by the American market research organization, Micron, Western Digital and other memory chip suppliers think that the product prices have fallen to the bottom, and began to cancel the mode of bulk trading at discounted prices in advance, and even began to raise prices. The survey agency predicts that the decline rate of memory chip prices will narrow from Q3, and the contract prices of some products are likely to rise from Q4. The situation of different product lines is different, and it is expected to fully recover next year.

Judging from the market news, the recovery of DRAM may be faster than that of NAND Flash. TrendForce Jibang Consulting recently estimated that the average price of NAND Flash in the third quarter continued to drop by about 3%-8%, and it is expected to stop falling and rebound in the fourth quarter, and the average price decline of DRAM in the third quarter will converge to 0-5%. The article "The Cold Wind of Memory Chips, Will Stop" published by the semiconductor industry on July 25th pointed out that DRAM bottomed out in the third quarter and NAND waited for another season. Earlier, some people in the industrial chain said that Samsung, SK Hynix and Micron all hoped to raise the contract price of DRAM orders in the third quarter, with a target increase of 7%-8%. However, because the terminal market has not seen obvious signs of recovery, there are obvious signs of seesaw in the upstream and downstream. In terms of NAND, recently, the market also heard that the original upstream NAND factory plans to raise the price from July.

In addition, according to the information of the Internet Office in May, Micron, which occupies a lot of land in China storage market, failed to pass the network security review. Ping An Securities Research Report pointed out that in 2022, Micron’s operating income in Chinese mainland was $3.311 billion. Analysts pointed out that if Micron’s business in China is limited, the niche storage market will naturally benefit first. In the niche storage field with relatively low technical barriers, Zhaoyi Innovation is the fastest growing and strongest company. In addition, Beijing Junzheng, the leader in vehicle storage, and Dongxin, the leader in domestic SLC NAND field, are expected to benefit. In the downstream storage module industry, Jumbo Long and Baiwei Storage also have strong competitiveness in the global market, among which Jumbo Long’s eMMC and UFS products have a global market share of 6.5%, ranking sixth in the world and first in China; The global market share of eMMC and UFS stored by Baiwei is 2.4%, ranking eighth in the world and second in China. The main suppliers of these two companies include Micron.

Analysts pointed out that although the inventory pressure downstream of memory chips is still there, the bottom is just around the corner through the dynamics of major manufacturers and industry analysis data. In order to catch up with the next wave of boom cycle after the turning point of the industry, Wanrun Technology, Liyuan Information, Shannon Core and Guoxin Technology and many other manufacturers have cross-border layouts. However, analysts also pointed out that even if the existing domestic storage companies, such as Zhaoyi Innovation, Beijing Junzheng, Eastcore and Puyan, are counted, most of the domestic storage products are at the SSD module and NOR Flash level, and it is difficult to touch the high-end DRAM and other markets vigorously promoted by international manufacturers, which makes it difficult for domestic storage manufacturers to enjoy the dividend in the incremental market and need to follow the trend in the supply and demand of the storage market.

On July 13th, Chongqing Institute of Artificial Intelligence of Shanghai Jiaotong University officially released the "Zhaoyan" large model in the West (Chongqing) Science City, which is also the first large language model independently developed in Chongqing.

With the global fire of ChatGPT, the big model has become the hottest topic at present, and 2023 will also become the year of big model generate. Statistics show that hundreds of large models have been released around the world, and more than 80 large models have been released in China since this year.

"The previously released general model represented by ChatGPT has some pain points in the industry, such as lack of domain knowledge, inaccurate system calls, and high deployment costs." Jin Shi, dean and chief scientist of Chongqing Institute of Artificial Intelligence of Shanghai Jiaotong University, said that for example, the general big model is like a "generalist", but due to the lack of professional knowledge and industry data accumulation, its industry depth is not enough, and the system call is not accurate, so when answering some highly professional questions, it may be "talking nonsense in a serious way".

"Zhaoyan" is committed to building a big model of the industry, just like a "professional". It is developed by Chongqing Institute of Artificial Intelligence of Shanghai Jiaotong University based on the world’s leading AI big model technology. By accumulating massive data, supplemented by unique data processing and AI training technology, it can achieve accurate and professional text output, and can realize the ability to select and call applications in natural language, helping to create personalized intelligent products.

"Does Jiangzhou in this Jiujiang official. My blue sleeve was wet mean Chongqing?" On the same day, the press conference demonstrated "Zhaoyan" and compared it with well-known large models in the industry.

The Chongqing Daily reporter saw that the "Zhaoyan" answer not only introduced the historical relationship between the name Jiangzhou and Chongqing, but also did not confuse Chongqing and Jiujiang, knowing that Jiangzhou is Jiujiang now. But another big model gives the wrong answer.

▲ Jin Shi, Dean and Chief Scientist of Chongqing Institute of Artificial Intelligence of Shanghai Jiaotong University, introduced the "Zhaoyan" big model. Reporter Zhang Yizhu photo

"’mega-words’ means’ mega-words accumulate and speak out in chapters’." Jin Shi said that this not only expresses that the process of creating a large model involves the collection and processing of massive data, that is, "mega-text accumulation", but also expresses that the large model can achieve high-precision and professional-level text output, that is, "speak out" and let people get the information they really need.

In addition, the research and development of "Zhaoyan" also focuses on miniaturization deployment. Through distillation learning, model compression and special reasoning chip, the cost of model training and reasoning is greatly reduced. For specific tasks in the industry, the quality of answers is not reduced, while the cost of model call is only one-fourth of that before miniaturization, so that more small and medium-sized enterprises can also apply large models and make model-based products more competitive in the market.

"To sum up,’ Zhaoyan’ has three characteristics: high precision, high efficiency and low cost, and better empowers manufacturing, medical care, finance, cultural tourism, law, service and other industries." Introduction of Jinshi. For example, in the medical field, "Zhaoyan" can provide medical assistance and improve the quality and efficiency of medical services by deeply learning medical data.

"In the past, medical services were limited by doctors’ professional knowledge and experience, and the consultation response speed was slow and the service quality was limited." For example, he said that "Zhaoyan" can deeply learn medical records and symptom descriptions, provide comprehensive and accurate diagnosis and treatment suggestions, and improve the response speed and quality of medical services.

At the press conference, Chongqing Institute of Artificial Intelligence of Shanghai Jiaotong University also signed contracts with Huayuan Computing Technology (Shanghai) Co., Ltd., Chongqing CCID Engineering Consulting Co., Ltd., Chongqing Yucun Technology Co., Ltd., China Mobile Communications Group Chongqing Co., Ltd., Beijing last romance Media Technology Co., Ltd. and Chongqing Saibao Industrial Technology Research Institute Co., Ltd., which will give full play to their respective advantages and promote the application of large-scale model technology in different industry scenarios such as manufacturing, finance, cultural tourism, education and medical care.

In the future, Chongqing Institute of Artificial Intelligence of Shanghai Jiaotong University will continue to optimize and upgrade in the vertical field of the industry according to the demand of Chongqing’s industrial layout, and apply "Zhaoyan" large model products to various fields to help the construction of the western (Chongqing) science city and the development of Chongqing’s digital economy.

Experts’ Interpretation of the Technical Guide for Derivation of Marine Biological Water Quality Standards (Trial)

  In order to protect the marine environment and promote the work of marine environmental standards, the Ministry of Ecology and Environment issued the Technical Guide for Derivation of Marine Biological Water Quality Standards (Trial) (HJ1260—2022) on July 18, 2022 (hereinafter referred to as the Guide). This is the first standard to guide and standardize the derivation of marine environmental standards in China, and relevant experts have answered relevant questions.
  Q: What is the significance of the publication of the Guide for China’s marine environmental protection?
  Researcher Yao Ziwei of National Marine Environmental Monitoring Center: Marine environmental benchmark is an important part of modern ecological environment governance system, and it is the basis and scientific basis for formulating China’s marine ecological environment quality standards, which can provide important support for China’s marine ecological environment risk assessment and emergency response.
  The current Standard for Seawater Quality (GB3097—1997) has played an important role in the prevention and control of marine pollution in China, but when the standard was first formulated, it was based on one or more foreign seawater quality standards (marine life, senses, health, etc.). As for marine biological water quality standards, there are great differences between different countries and even the same country in different periods due to the differences in derivation methods and concerned species. When conditions permit, countries should carry out relevant benchmark research according to their own marine ecological environment characteristics.
  The publication of the Guide is of great significance for strengthening the research of marine environmental standards in China, accelerating the transformation and application of research results, and improving the level of marine ecological environmental protection.
  Q: Since the 1980s, some developed countries and international organizations have successively issued water quality standards for marine organisms. In contrast, what are the unique features of the Guide in terms of methods and technical requirements?
  Researcher Wang Ying, National Marine Environmental Monitoring Center: Since 1980s, the environmental management departments of the United States, the European Union, the Netherlands, Australia/New Zealand and Canada and other countries and international organizations have successively issued technical guidelines for deriving water quality standards for protecting aquatic organisms (freshwater organisms and marine organisms) and water quality standards for protecting marine organisms according to their environmental management needs and water pollution status. In the process of compiling the Guide, domestic and foreign scientific research achievements were fully absorbed and used for reference.
  Methodologically, it is stipulated that the species sensitivity distribution method is used to derive the water quality standards of marine organisms, which is the mainstream method to derive the water quality standards of freshwater and marine organisms in the world at present, and it is also the method stipulated in the Technical Guide for Deriving Water Quality Standards of Freshwater Organisms (HJ831—2022).
  In terms of technical requirements, the characteristics and working basis of China’s marine ecosystem are fully considered: first, the toxicity data of marine species in China are required to be used to derive the water quality standards of marine organisms; Secondly, according to the species distribution of marine ecosystems in China, the minimum toxicity data requirements of "5 families and 8 species" based on the characteristics of marine biota in China are put forward; Thirdly, the calculation method of acute value/chronic value of the same effect is proposed, which solves the problem that different types of toxic effects have different weights and achieves the purpose of better protecting marine species in China. At present, only the European Union has put forward this technical requirement internationally.
  Q: How to consider the minimum toxicity data requirements of "8 species in 5 families" based on the characteristics of marine biota in China?
  Yan Zhenguang, researcher of china environmental science Research Institute: According to statistics, there are more than 3,000 species of microalgae and macroalgae in China, accounting for 11% of the total marine species in China; Arthropoda, Chordata, Annelida, Mollusca, Echinoderm and Rotifera are the main animal groups in China’s sea areas, with more than 17,000 species, accounting for 59% of the total marine species in China. The number of marine species in the above key groups of marine life in China accounts for more than 70% of the total marine species in China.
  In order to make the derivation of marine biological water quality benchmark reflect the characteristics of marine ecosystem in China, it is a basic principle to determine the minimum toxicity data requirements for the derivation of the benchmark. The tested species in seawater should cover the key groups of marine organisms in China, which is embodied in the following aspects: 1 family of microalgae or macroalgae, 2 families of crustaceans in Arthropoda and 1 family of bony fishes in Chordata; Other phylum, such as annelids, molluscs, echinoderms, rotifers, etc., or an unused family among crustaceans and teleost fishes.
  The minimum toxicity data requirements of 8 species are mainly considered from the following two aspects: from the point of view of mathematical statistics, the more species, the better the model effect; From the point of view of the robustness of species sensitivity distribution model and the reliability of reference value, if the toxicity data covers key biological groups, then the uncertainty of reference value based on more than 8 species is within the acceptable range. There are eight criteria for evaluating the number of species as "good" in the minimum toxicity data requirements of the Australian/New Zealand Technical Guidelines for Derivation of Water Quality Standards.
  At the same time, from the perspective of protecting marine biodiversity and marine ecology, it is clear that alien invasive species should not be used as a benchmark to deduce the tested species, such as marine microalgae that produce microcystins and Spartina alterniflora that compete with native species for nutrition.
  Q: We have noticed that there are great differences in the exposure time of different kinds of marine life in the Guide. How do you consider it?
  Professor Tan Qiaoguo of Xiamen University: Based on the standard testing methods of marine ecotoxicology at home and abroad, in order to protect marine species in China more pertinently, on the basis of analyzing the life history and reproductive characteristics of different types of marine species, the Guide puts forward the differential exposure time for 7 categories and 43 families of marine organisms such as algae, rotifers, annelids, molluscs, arthropods, echinoderms and chordates. According to the acute toxicity test, the generation cycle of Brachionus plicatilis is only about 2 days, and it is recommended that its exposure time should not be longer than 48 hours. For most arthropods and fish, the generation cycle is long, and the exposure time is recommended to be no more than 96 hours. According to the chronic toxicity test, the generation cycle of cladocera such as Daphnia mongolica is 5-7 days, and the exposure time is recommended to be no less than 5 days. However, the generation cycle of fish such as medaka can reach 3-4 months, and it is recommended that its exposure time should be no less than 21 days.
  Q: As the vice chairman of the National Expert Committee on Environmental Standards, I would like you to talk about what work needs to be promoted in the field of marine environmental standards in China during the 14 th Five-Year Plan period.
  Researcher Wang Juying, National Marine Environmental Monitoring Center: Marine environmental standards mainly include marine biological water quality standards and sediment quality standards for protecting marine ecosystems, nutrient standards for preventing water eutrophication, and people’s health standards for consuming seafood and marine recreational water.
  China’s marine environmental benchmark research began in 1980s, and made some progress. For example, related research provided direct technical support for the formulation of Marine Sediment Quality (GB18668—2002); The national "863" special project "Research on Key Technologies for Determining the Threshold of Marine Environmental Effects of Typical Organic Pollutants from Land-based Sewage Discharges into the Sea" and the marine public welfare scientific research special project "Research and Formulation of Offshore Seawater Quality Standards/Standards" won the first prize and the second prize of the Marine Engineering Science and Technology Award respectively.
  China’s sea area spans temperate zone, subtropical zone and tropical zone, and the marine ecosystem is diverse. From the perspective of protecting China’s marine ecosystem, during the Tenth Five-Year Plan period, based on protecting the integrity of China’s marine ecosystem, we should speed up the research and construction of China’s seawater quality benchmark system, develop the target pollutant marine biological water quality benchmark that has an important impact on China’s marine ecological environment quality, carry out the ecological risk threshold research of new pollutants such as endocrine disruptors, and develop the nutrient water quality benchmark of key sea areas such as Bohai Sea and South China Sea based on classification and zoning.
  Experts in the field of marine environmental benchmark research in China are distributed in different institutions. In order to ensure the smooth progress of the marine environmental benchmark work in the 14th Five-Year Plan, we should give full play to the role of the National Environmental Benchmark Expert Committee as a think tank platform, and the superior research teams in the United Nations should work together to organize joint research. Through cooperation in a wider space and at a higher level, we will contribute wisdom and strength to the marine environmental benchmark work in China, better serve the marine ecological environmental protection in China, and meet the urgent need to speed up the modernization of the ecological civilization governance system and governance capacity.

Reporter’s investigation: excess capacity projects running red lights

  CCTV News:De-capacity is a major task of economic work this year. At present, the steel and coal industries have basically completed the task of de-capacity this year. The cement industry is also one of the serious overcapacity. The task of de-capacity is also very serious. Not long ago, someone told the column reporter that the excess capacity of the cement industry in Heilongjiang Province has not only failed to go in recent years, but new projects have been launched and the production capacity has increased. What is going on?

  In Harbin at the end of November, the outdoor temperature reached MINUS 20 degrees. In Yuquan Town, Acheng District, a huge construction site is under construction.

one

  Reporter:It’s so cold that we haven’t stopped working yet. Are we in a hurry or something?

  Workers:I’m in a hurry. Can you stop work?

  Reporter:Never stopped working?

  Workers:No, I’m in a hurry

  Reporter:Who urged, engineering department.

  Workers:Engineering department, don’t let me go, it’s MINUS 26 degrees.

one

  Outdoor construction is still going on at MINUS 26 degrees, so it seems that the construction period is tight enough. It is understood that this is a production line with a daily output of 7,200 tons being built by Jidong Cement Heilongjiang Co., Ltd.. It is understood that cement is a serious surplus industry, and it is also one of the industries that focus on capacity reduction at present. In view of the serious overcapacity problem in cement and other industries, the State Council issued a document as early as 2009 to strictly control new cement projects. In October, 2013, Guo Fa [2013] No.41 again requested all localities and relevant departments not to approve and record new capacity projects in industries with serious overcapacity in any name or in any way.

  So is this cement project under construction a new capacity? The reporter came to the company office to learn about the situation.

  Reporter:We want to find our general manager or be in charge of production and operation. Can you lead us to knock at his office?

  Staff of the General Department of the Company:It’s beyond my scope. It’s not my responsibility.

  Reporter:Whose scope is that?

  Staff of the General Department of the Company:I don’t know, because I am responsible for communication and reporting, and I don’t care about anything else.

  Reporter:Waiting for your director, right? Director of the general department, right?

  Staff of the General Department of the Company:I can’t tell you to wait, and I don’t know who you should look for.

  For the reporter’s visit, the company is unwilling to cooperate. In fact, for cement, an industry with serious overcapacity, it does not mean that new projects cannot be carried out. According to the "Implementation Measures for Capacity Replacement of Some Industries with Serious Overcapacity" issued by the Ministry of Industry and Information Technology in July 2015, it is clearly required that the capacity replacement plan must be formulated for the project construction of industries with serious overcapacity, and equal or reduced replacement should be implemented. That is to say, in order to add a new project in a surplus industry like cement, it is necessary to replace the same capacity at the same time, that is to say, to remove the same capacity. Capacity replacement is the most critical link for new projects to be launched. So did they do this work for this huge project?

  After many twists and turns, the reporter interviewed the general manager of Jidong Cement Heilongjiang Company by telephone.

  Reporter:Have all your capacity replacement projects been replaced?

  Zhou Zhaoyin, General Manager of Jidong Cement Heilongjiang Company:Hmm.

  Reporter:When is the replacement?

  Zhou Zhaoyin, General Manager of Jidong Cement Heilongjiang Company:On March 7th this year, it was announced in the official website of the provincial government.

  This is the announcement issued by the Heilongjiang Provincial Industry and Information Technology Commission on the website of the Heilongjiang Provincial Government. The main content is the elimination of the equivalent replacement scheme of this project. The reporter found that all the listed eliminated enterprises were eliminated in 2011. However, according to the "Measures for Capacity Replacement" promulgated by the Ministry of Industry and Information Technology in July 2015, it is clearly required that the excess capacity listed in the announcement in 2013 and beyond can be used for capacity replacement in industries with serious overcapacity. So how can these eliminated capacity in 2011 be included?

  Reporter:I read the plan announced on March 7, but in that announcement, it was mentioned that all the years of obsolete enterprises were in 2011, right?

  Zhou Zhaoyin, General Manager of Jidong Cement Heilongjiang Company:I don’t know about that.

  Reporter:You made this, and you submitted the plan?

  Zhou Zhaoyin, General Manager of Jidong Cement Heilongjiang Company:We didn’t make this plan.

  Reporter:Who made the plan?

  Zhou Zhaoyin, General Manager of Jidong Cement Heilongjiang Company:Then I don’t know this matter.

  Speaking of the most critical procedure to start construction — — The general manager was suddenly vague about the capacity replacement plan. The reporter then went to the Industrial Policy Department of the Heilongjiang Provincial Industry and Information Committee, which issued this announcement, to understand the situation.

  Reporter:Why is the production capacity in 2011 obviously inconsistent?

one

  Li Xuedong, Director of Industrial Policy Division of Heilongjiang Industry and Information Technology Commission:It must be used as a new project after 13 years, and it must not be used. Considering that it is a problem left over from history in the province, all projects under construction in violation of regulations can use the indicators of 13 years ago.

  Reporter:But it’s not an illegal project under construction?

  Li Xuedong, Director of Industrial Policy Division of Heilongjiang Industry and Information Technology Commission:To say the least, it has been under construction since 10 years.

  According to the director, because this project was first started in 2010, it has not been able to get legal construction for various reasons. Therefore, the province will make an exception when examining and approving, and treat it as an "illegal project under construction". According to relevant policies, if it is an illegal project under construction, the indicators before 2013 can be used. Can this statement stand?

one

  The reporter found that at the end of this announcement, the construction project was marked as (new). What is the reason behind this obvious contradiction?

  Li Xuedong, Director of Industrial Policy Division of Heilongjiang Industry and Information Technology Commission:Mainly considering that the enterprise has invested in the early stage, when we consider studying its announcement, the enterprise has invested more than 700 million yuan, considering that 2010 is a project to attract investment in our province.

  It is worth noting that compliant capacity replacement is a prerequisite for the enterprise to start construction. Why did this enterprise invest more than 700 million yuan before the announcement of capacity replacement? It turns out that this is the second time that Heilongjiang Provincial Industry and Information Committee has approved the capacity replacement index for Jidong Cement Heilongjiang Project. The first time was in 2014, two years ago, the Heilongjiang Provincial Industry and Information Committee submitted the Letter on Confirming the Use of the Index of Eliminating Backward Production Capacity of Jidong Cement Heilongjiang Co., Ltd. to the Heilongjiang Provincial Development and Reform Commission, and then the Heilongjiang Provincial Development and Reform Commission approved the project accordingly. As a result, the project obtained a "birth certificate" and began to be put into construction. However, this capacity indicator replacement plan was not reported to the Ministry of Industry and Information Technology according to the procedure. In September 2014, after investigation, the Ministry of Industry and Information Technology sent a letter to the Heilongjiang Provincial Industry and Information Committee, proposing that this project should be regarded as a typical illegal approval project for informed criticism in the whole country. .

  Li Xuedong, Director of Industrial Policy Division of Heilongjiang Industry and Information Technology Commission:The Ministry of Industry and Information Technology asked the province to cancel this plan, because as far as we know, what was the reason for the main cancellation plan at that time, that is, we did not declare it to the state as required, and made a public announcement. Second, it is possible that some indicators may be reused according to the requirements of the Ministry of Industry and Information Technology.

one

  Subsequently, the Heilongjiang Provincial Industry and Information Committee sent a letter to the Heilongjiang Provincial Development and Reform Commission, revoking the Letter on Confirming Jidong Cement Heilongjiang Co., Ltd. to use the index of eliminating backward production capacity. Without the confirmation of the index of eliminating backward production capacity, it also means that this project is "new production capacity", which is strictly prohibited according to the relevant documents of the State Council. However, after more than a year of silence, the project was launched again. At the end of 2015, the bidding advertisement for this project appeared on the Internet, and the project basis was still the approval issued by the Development and Reform Commission of Heilongjiang Province. The Development and Reform Commission of Heilongjiang Province received a letter from the Heilongjiang Provincial Industry and Information Committee revoking the use of indicators to eliminate backward production capacity. It is reasonable to say that the approval of this project should be revoked, but they did not do so. What is going on?

  Reporter:He revoked the letter. Why did your No.107 document become invalid accordingly?

  Lin Dayong, Director of Industrial Investment Division of Heilongjiang Provincial Development and Reform Commission:Because later, after the cancellation of the Industry and Information Committee, they have been studying the production capacity index, and the province has been studying this matter and how to solve it after the withdrawal.

  Reporter:What about the results of later research?

  Lin Dayong, Director of Industrial Investment Division of Heilongjiang Provincial Development and Reform Commission:I asked the Ministry of industry and information technology, and then I came out with the corresponding documents.

  The so-called study of the corresponding documents is the announcement made by the Provincial Industry and Information Committee on the Internet in March 2016, which is filled by the outdated elimination indicators in 2011. This behavior is obviously inconsistent with the original intention of the country to go to capacity. In April 2106, the Industry Department of the Ministry of Industry and Information Technology sent a letter to the Heilongjiang Provincial Industry and Information Committee again, pointing out the problems in this scheme and asking them to readjust the capacity replacement scheme of Jidong Cement.

  Li Xuedong, Director of Industrial Policy Division of Heilongjiang Industry and Information Technology Commission:We require enterprises to replace the same amount according to the requirements of the Ministry of Industry and Information Technology. At present, our enterprises are also looking for this indicator. We are also communicating with other provinces and looking for it.

  On the one hand, the Ministry of Industry and Information Technology issued a document twice to stop, on the other hand, this project has been under construction. So what is the state of the cement industry in Heilongjiang Province? Is there still market space? The reporter also conducted an investigation in the local area. This is Harbin Xiaoling Cement Company, which is only 10 kilometers away from Jidong Cement Project. The reporter of this company’s factory saw that it was empty and there was no sign of production. The general manager of the company told the reporter that because of poor sales in winter, they stopped working at the end of October. This winter, they will stop working for a total of five months, and employees can only receive half of their wages.

  50% of the salary, if we remove the deducted personal insurance, we will get very little salary.

  Reporter:Can you get a part-time job in these five months, or find something else to do?

  Employees of Harbin Xiaoling Cement Co., Ltd.:Working in Heilongjiang in winter is not easy to find, and most of them are difficult to find employment opportunities.

  It is understood that the production capacity of Jidong Cement’s new project is equivalent to nearly 50% of the current cement sales in Harbin. Unlike other products, cement is a special product with a very close sales radius. It is undoubtedly worse to have such a big MAC project at home.

  In this case, why did Jidong Cement insist on investing in this project?

  Zhou Zhaoyin, General Manager of Jidong Cement Harbin Company:His powder is surplus, and his clinker, because the so-called indicators including the current de-capacity are the indicators of approved clinker. In recent years, Heilongjiang Province refers to clinker, and his total clinker is not surplus.

  Clinker refers to a semi-finished product for manufacturing cement, and we also investigated the local clinker production. Pennsylvania Cement Co., Ltd. has two clinker production lines with a daily output of 5,000 tons. The general manager of the company told reporters that they need to stop work not only in winter but also this summer because of overcapacity.

  Zhang Yongsheng, Deputy General Manager of Heilongjiang Binzhou Cement Co., Ltd.:In May this year, it was considered that the whole cement industry in the three northeastern provinces joined forces to limit production and reduce inventory, and stopped production for 20 days from May 15 to June 5, in order to digest the original backlog of inventory.

one

  According to the statistical data of Heilongjiang Cement Association at the end of 2015, the utilization rate of cement production in Heilongjiang Province in 2014 was 43.4%, and the clinker project under construction in Jidong Cement was also 71.5%. According to industry standards, it is normal for the utilization rate to be above 80%. Obviously, the local production capacity is seriously surplus.

  In the interview, Heilongjiang Building Materials Association is calling the cement enterprises in the whole province to hold a coordination meeting of peak-shifting and shutdown in winter, which means that all cement enterprises in the whole province will stop working from December 1.

  Reporter:Is the purpose of your wrong peak because?

  Han Shitao, President of Heilongjiang Building Materials Association:There are two practical purposes, one of which is to avoid pollution superposition in the heating period in Northeast China, and the second is actually to control production capacity. It is a necessary measure for us to curb production capacity from the perspective of the industry.

  Reporter:There are four months of production capacity (excess) in a year.

  Han Shitao, President of Heilongjiang Building Materials Association:Four months, actually a year is five months.

  Local insiders believe that Jidong Cement’s violation of regulations comes from the investment inertia of state-owned enterprises. If it was a private enterprise, it would have stopped working long ago.

  Reporter:What are the deep-seated reasons?

  Han Shitao, President of Heilongjiang Building Materials Association:Enterprise investment impulse has a kind of inertia. The investment inertia has not been contained. It has not been sober yet. In 2011, preparations began. Up to now, he may have prepared for a long time and made some investments. He has invested, so it is very difficult for him to brake.

  Reporter:Just tell me about your cement company? What’s your opinion?

  Head of Yatai Cement:Overcapacity, after he came down, our whole Heilongjiang market was completely destroyed. Now he is in violation of laws and regulations. Now it is in violation of laws and regulations, which does not conform to the policies of the Ministry of Industry and is still on the market.

  Is there a way for enterprises to realize investment without violating the requirements of de-capacity? In fact, the Building Materials Association has also put forward many suggestions. Enterprises are welcome to invest without increasing production capacity.

  Han Shitao, President of Heilongjiang Building Materials Association:At that time, we put forward a point of view, that is, to eliminate the backward and non-dominant production capacity around Harbin and replace it with him in the same amount, which is beneficial to the regulation of the whole market.

  Reporter:He won’t do it?

  Han Shitao, President of Heilongjiang Building Materials Association:Why? If you want to eliminate these production capacities, you need to take money. Whoever pays this money, there is no better way.

one

  It is understood that the total investment of Jidong Cement Harbin Project is as high as 1.7 billion yuan, but it is unwilling to take money to eliminate production capacity, which leads to the delay in completing the compliant production capacity replacement. Following the failure of the Ministry of Industry and Information Technology to issue a document twice, the General Office of the State Council also issued a document to the Provincial Industry and Information Committee in October this year asking them to rectify as soon as possible.

  Li Xuedong, Director of Industrial Policy Division of Heilongjiang Industry and Information Technology Commission:This time, the explicit request was contacted by the Ministry of Industry and Information Technology of the National Development and Reform Commission, which was sent by the State Council.

  Reporter:I sent you another message in October?

  Li Xuedong, Director of Industrial Policy Division of Heilongjiang Industry and Information Technology Commission:They reported it to the State Council, reported it in September, and gave us the news in October.

  Reporter:Do you have time to ask now?

  Li Xuedong, Director of Industrial Policy Division of Heilongjiang Industry and Information Technology Commission:Not in time, but we have been actively doing it, and we are trying to finalize this project as soon as possible.

  Reporter:But will it all be put into production and ignited?

  Li Xuedong, Director of Industrial Policy Division of Heilongjiang Industry and Information Technology Commission:That can’t be helped.

  When the reporter left, the project was still under construction.
