The Paper News: On August 12th, the Central Meteorological Observatory issued the first high-temperature red warning this year. On the 13th, the high-temperature red warning continued.

The Central Meteorological Observatory announced at 8: 00 on the 13th that in the past day, the hot weather in the south attracted much attention, with the local temperature of 41 ~ 43℃ in eastern Sichuan, southwestern and northern Chongqing, southeastern Shaanxi, western Hubei, southeastern Anhui, southern Jiangsu and central and northern Zhejiang, and the local temperature of Zhushan in Hubei was 44.3℃.

On August 10, 2022, the "stove" Chongqing continued to have hot weather, and many citizens were playing with water in the water park of Fuling wine town to cool off the heat. IC diagram

The Central Meteorological Observatory predicts that the intensity and range of high temperature weather from the Sichuan Basin to the middle and lower reaches of the Yangtze River will still be at its peak on the 13th to 16th, with obvious extremes. Today (August 13th), parts of southeastern Shaanxi, eastern Sichuan, Chongqing, western and southeastern Hubei, northern Hunan, northwestern Jiangxi, central and southeastern Anhui, southern Jiangsu, Shanghai and central and northern Zhejiang can reach 40 ~ 42℃.

According to the list of today’s high temperature released by official website, China Meteorological Bureau, as of 14: 00 on the 13th, the highest temperatures in the top ten of the high temperature list have all exceeded 41℃, with the highest ones in Hubei Three Gorges and Chongqing Fengjie reaching 42.1℃.

Chen Tao, chief forecaster of the Central Meteorological Observatory, explained that the main cause of the high temperature weather has something to do with the abnormal atmospheric circulation. Judging from the current monitoring, the western Pacific subtropical high has a large range and strong intensity. Under its control, the southern part of China is controlled by downward flow as a whole, with clear skies and partly cloudy, and the near-surface heating is relatively strong under the influence of sunshine radiation during the day, so a wide range of high temperature weather has appeared.

In the top ten of the high temperature list, there are four places in Hubei Province, namely Yunxian (41.9℃), Baokang (41.9℃), Zhushan (41.8℃) and Shiyan (41.4℃), and there is another place in Chongqing, Tongnan (41.5℃). In addition, Anhui Maanshan (41.7℃), Zhejiang Pujiang (41.5℃) and Zhejiang Wuyi (41.4℃) are also among them.

Recently, Hubei and Chongqing have been subjected to high temperature tests for several days.

According to the message of "Hubei Publishing" on WeChat WeChat official account, since May this year, it has been sunny, hot, hot and rainy in Hubei Province, and many places have published high-temperature red warning signal for several days. On August 12th, the highest temperature of 73 stations in the province exceeded 37℃, and 19 stations exceeded 40℃. At 16: 26 on the 12th, the temperature at Zhushan Station reached 44.3℃, setting a new record for the highest temperature in Hubei since the meteorological record (the original record was 43.4℃ in Zhushan on July 20th, 1966).

According to WeChat WeChat official account’s "Chongqing Release", from July 29 to August 12, a large range of continuous high temperature weather occurred in Chongqing. The highest daily temperature in Hechuan District, Bishan District, jiangjin district, Changshou District, Fuling District, Fengdu County, Wanzhou District, Kaizhou District, Yunyang County, fengjie county, Wuxi County and Pengshui County and some areas in the central city exceeded 40°C for 5-11 consecutive days.

At 21: 00 on August 12th, Chongqing Municipal Health and Wellness Committee and Chongqing Meteorological Bureau upgraded the "Secondary Warning of High Temperature Heatstroke" issued at 15: 30 on August 10th to "Primary Warning of High Temperature Heatstroke". According to the meteorological department of Chongqing, the first-level warning of high-temperature heatstroke is the first release since the publication of the Emergency Plan for High-temperature Heatstroke in Chongqing, and it is also the first release this year.

Original title: Today, the top ten in the national high temperature list broke 41 C, and the highest temperature in Hubei and Chongqing was 42.1 C.

　　

This year, Project ONE, the 50th anniversary model of AMG, received high attention. There are two main reasons: first, it is expensive, and only 275 sets are limited to production, and the price is 2.27 million euros.

Secondly, the data is too strong. This car is equipped with F1 racing car that should only appear on the track. It will be more than 1014 horsepower, and the acceleration of 100 kilometers will take 2 seconds, while the acceleration of 0 to 200 kilometers will only take 6 seconds. What’s even more incredible is that this car is only 1.6 liters, with four motors.

　　

So the question is, how does this sports car make the power so strong?

First of all, the power system of AMG Project ONE is a hybrid system consisting of a 1.6T V6 and four motors. This one originated from the F1 Championship for the 2015 season. Lewis hamilton also won the championship this year with this excellent performance.

According to the published data, 1.6T booster plus 4 motors, the total reached 746kW. One of the four motors provides pumping power for the turbine, which is 90kW. This motor does not participate in direct work to drive the whole vehicle, but provides power source for the electronic turbine. The other three motors are 120kW, which can directly provide power for the whole vehicle. This hybrid mode is a parallel mode.

　　

The advantage of parallel mode is that the energy loss is small, and each motor can drive the whole vehicle independently. In addition to transmission loss and system error, the sum can be calculated by superposition. This power system is about 746kW, minus the superposition of three motors of 360kW, so this 1.6 liter will reach 386kW.

Is it ridiculous? This is something that you can’t even think about. Generally, it takes more than 4L to achieve 386kW, but it can be achieved on a 1.6L platform, just like a 3-year-old child lifting a weight of 80kg.

The maximum NA of conventional 1.6L is only about 90kW, and the rotating speed is 6000rpm. If the rotating speed is doubled to 12000rpm, the times of doing work per unit time will be doubled. Plus, if it is increased by 40%, it will reach 252kW.

　　

So how did this model achieve 386Kw? This AMG with a F1 heart not only uses exhaust gas to drive the turbine to increase the intake density, but also uses a 90kW motor to drive the electric turbine to increase the intake density, so it is entirely possible to reach 386kW.

This is the secret weapon of Super Engine with super power, but there are many problems to be solved to make it work normally. The first is inertia force. With the increase of rotational speed, the average speed is 7-12M/S, and the acceleration can reach about 200 g, while the rotational speed of Super Engine is twice or more than that of the conventional 1.6L. If designed according to the routine, the acceleration can reach 400 g, which is a great design challenge.

How does Super Engine do to overcome such a large inertial force? First of all, this is the advantage of a V6, V-type. For the whole vehicle, it can lower the center of gravity, and the effect is better. For me, first of all, the V-shape can decompose the inertial force into two opposite directions in the horizontal plane, and the inertial force can cancel each other out. So we only need to overcome the vertical component.

　　

Secondly, 1.6L is divided into six cylinders, and the volume of each cylinder is reduced from 0.4L to 0.266L. The mass and volume of the connecting rod can be made smaller, so the rotation speed can be improved and the inertia force can be reduced.

In addition, the moment arm of is 1/2, so the Super Engine must be as short as possible, and F1 will generally set/to 2.5, so that the inertia force will be reduced at high speed.

In addition, the system, the opening and closing of the conventional camshaft drive, can no longer meet the reliability requirements at such a high speed, plus the force attenuation, the conventional steel is completely incompetent for this work. Therefore, a high-pressure nitrogen pressure tank must be equipped separately, and the pressure release gas pushing mechanism of the pressure tank can be controlled by calculating the opening and closing time of the electromagnetic valve, so that the reciprocating motion can be carried out quickly.

Super Engine rotates at 12,000 revolutions per minute, ignites 200 times per second, and opens and closes 200 times per second. The strength and reliability requirements of these core components, as well as the accuracy of ignition design, are very high, among which titanium alloy is the best choice for material selection.

　　

It needs to be emphasized here that the increase of intake density is directly proportional to the temperature in the intercooling system of this car. The intake air volume of 4.5L is inhaled in a unit time of 1.6L According to the conventional conversion, the intake pressure will reach about 3 bar, and the temperature after vortex will be much higher than that of traditional supercharging, so it is necessary to make a special design for the intercooling system to cool the intake temperature.

Generally, the service life of F1 racing car is 1000 kilometers, over after the runway is completed, which is caused by different design concepts. F1 is to pursue the ultimate speed and win the race. If the speed is designed to be above 15,000 rpm and other performance is sacrificed to improve the speed, such as reducing the weight of all parts, its reliability will not be considered, because winning the game is more important than everything else.

The service life of AMG Project ONE is 50,000 kilometers, which is much longer than that of F1′ s1,000 kilometers. I think there are two main reasons: first, the speed is reduced to about 11,000 rpm, so the use environment of parts is much milder than that of F1; Second, the use environment of the car, F1 is basically the biggest running on the track, and the maximum potential of F1 is fully exerted. However, AMG Project ONE cannot run at full speed within its life cycle, but should have its own durable working conditions.

　　

Finally, the technology of F1 events will be decentralized to the civilian field, bringing us such a high-performance product. In my opinion, this is just a high-end souvenir for the 50th anniversary of AMG, to let the world know the technology and look forward to it. However, it didn’t achieve real civilian use, 50,000 kilometers, and the conventional car was only maintained for 3 ~ 5 times, but AMG Project ONE had to change the powertrain to continue to use. In addition, the pure electric mode only lasted for 20 kilometers, which was a bit embarrassing.

Therefore, AMG Project ONE can improve the reliability and battery technology to be truly commercialized.

　　CCTV News:From July 18th to 21st, it was the time for more than 21,000 junior high school graduates in Yan ‘an City, Shaanxi Province to announce their senior high school entrance examination results and fill in their volunteers. After the results were announced, many candidates found that there was a big discrepancy between their English scores and their estimated scores, so volunteering for the senior high school entrance examination was interrupted. The local education department said that due to the lack of review, English scores were wrong.

　　The parents of the students said that the answer came out the next day after the exam. The child estimated the score, which was more than 70, and the final score was 51. I feel that the gap is a bit big.

　　Another student’s parents said that after her English score came down, she got a score of 60, and she estimated her own score of 80, and she usually got a score of 80.

　　After discovering this problem, I went to the school to report it. The class teacher said that I could write an application and go to the city to check it again.

　　When parents went to the local examination center to reflect their problems, they found that many students had doubts about their English scores. The published results differ from the child’s estimated results by 20 to 40 points.

　　Li Jinke, deputy director of Yan ‘an Education Bureau, said that after the senior high school entrance examination this year, some of our candidates asked to check the papers. After manual review, we found that the candidates were right. This is the problem of our marking work.

Marking screen

　　The education department of Yan ‘an replied that the problem occurred when scanning the candidates’ English answer sheets, and a test paper scanner failed, which led to incomplete recognition of some candidates’ answer sheets and missed judgments, and some students lost points.

Marking screen

　　According to the relevant regulations of the local examination, after all the scanning work is finished, the relevant personnel should proofread and correct the input data to ensure the integrity and accuracy of the data. In this regard, Yan’ an Admissions Examination Management Center said that they handed over the proofreading and re-examination work to a third-party unit that provided marking technical services.

　　Because of the regulatory obligation, Yan ‘an Admissions Examination Management Center conducted a random inspection of some examination papers.

　　The reporter tried to contact the person in charge of Xi ‘an Guanyu Technology Co., Ltd., a third-party unit providing marking technical services, but the phone of the person in charge of the company was always turned off.

　　From July 19th to 22nd, the Yan ‘an Municipal Commission for Discipline Inspection, the Municipal Examination Management Center and other units organized staff to re-grade and re-examine the objective questions of all candidates and all examination papers, and found that there were 3,252 differences in English scores, and there were no mistakes in other subjects.

　　At present, the local authorities have announced the results after the review and organized students to fill in their volunteers.

　　The chief of the senior high school entrance examination department of Yan ‘an Examination Management Center was dismissed because of the mistakes in the results of the senior high school entrance examination. On the 27th, the local discipline inspection and supervision organs started the accountability procedure. In addition, for Xi’ an Guanyu Technology Co., Ltd., a third-party unit that provides marking technical services, after deducting all the service fees for this marking, the education department will investigate the responsibility of the enterprises involved according to law.

　　Xinhuanet Beijing April 22nd (Wang Ying) Today is the 49th Earth Day. Protecting the earth’s environment and protecting the common home have attracted much attention. There is only one earth for human beings. How can we cherish our blue home? These little efforts in life make it easy for us to add green to the earth.

　　Turn off the lights without wasting power resources.

　　Due to negligence or trouble, many people often forget to turn off the lights or power in their lives. At present, 60% of the electricity used in our life depends on burning coal, and 400 grams of coal is burned for every kilowatt hour. Burning coal not only consumes the earth’s resources, but also produces a lot of carbon monoxide, sulfur dioxide, nitrogen dioxide and dust, which seriously pollutes the environment. Develop the habit of turning off the lights at will, and unplug the power supply for unused electronic equipment in time, which can not only save electricity, but also protect natural resources.

　　Green and low-carbon travel is environmentally friendly and healthy.

　　In recent years, the concept of green and low-carbon travel has been deeply rooted in people’s hearts. In daily life, if you are a car owner, if conditions permit, you can try to walk, ride a bike or take public transport to reduce the use of motor vehicles. When the weather is fine, you can also go outdoors for cycling and walking, which not only exercises your body, relaxes your body and mind, but also reduces energy consumption.

　　Save paper to make the forest more lush.

　　In daily work and life, the consumption of paper is amazing. As we all know, paper is made of trees. The more paper is consumed, the more the number of trees decreases. Save paper from scratch, such as printing documents can be double-sided; Used paper can be used in reverse; Use paper reasonably and refuse to use it excessively (such as pumping paper and toilet paper); Put a handkerchief in your pocket to reduce the use of paper towels.

　　Use less plastic bags to protect soil and atmosphere.

　　The pollution of plastic bags to soil is self-evident. To protect the global environment, we should reduce the use of plastic bags and keep cloth bags or reusable shopping bags when going out. At the same time, use disposable things (such as disposable bowls, chopsticks and cups) as little as possible.

　　Garbage sorting makes the living environment fresher

　　We produce a lot of garbage every day, and disorderly mixing not only leads to the spread of odor, but also pollutes soil and groundwater. In recent years, garbage classification has been widely advocated, and we should also respond positively in daily life, separate waste, make use of existing manufacturing capacity, recycle recycled products, and turn waste into treasure.

　　Save water, the blue planet can’t lose a drop.

　　A dripping faucet wastes 1 to 6 liters of water a day, and a leaky toilet wastes 3 to 25 liters of water a day. Water resources are not inexhaustible. To save water, we should start from the dribs and drabs of life (washing, bathing, cooking, washing cars, washing clothes, etc.). For a simple example, the flushing toilet is the key equipment for household water use. In the past, many families directly discharged the wastewater, but now many people began to keep the wastewater for flushing the toilet.

　　Participate in planting trees to add more green to the earth.

　　A 50-year-old tree produces oxygen worth about $31,200. Absorbing toxic gases and preventing air pollution is worth about $62,500; Increase the soil fertility value by about $31,200; Water conservation is worth $37,500; Providing breeding grounds for birds and other animals is worth about $31,250; Resulting in protein worth $2,500. Excluding the value of flowers, fruits and wood, the total value is about $196,000. In life, take part in more tree planting activities to add more green to the earth.

　　Buying energy-saving appliances saves more than electricity bills.

　　According to relevant data, under the same wattage, an energy-saving lamp saves 80% more energy than an incandescent lamp, prolongs its average life by 8 times, and radiates only 20%. This is just a light bulb. If we replace all the high energy-consuming appliances in our home with energy-saving appliances, or buy energy-saving appliances directly, we can not only save electricity expenses, but also reduce electricity consumption.

　　Cctv news: Pay attention to the situation of valsartan in Zhejiang Huahai Pharmaceutical Company. Yesterday (July 29th), the spokesperson of National Medical Products Administration introduced the situation of trace N- nitrosodimethylamine (NDMA) impurities detected in valsartan raw materials of Zhejiang Huahai Pharmaceutical Co., Ltd.　

　　On July 6th, Zhejiang Huahai Pharmaceutical reported to National Medical Products Administration that a small amount of N- nitrosodimethylamine (NDMA) impurities were detected in the raw materials of valsartan for export, and voluntarily disclosed relevant information to the public according to relevant regulations and requirements.

　　Zhejiang Huahai Pharmaceutical Co., Ltd. immediately suspended the release and delivery of all valsartan raw materials in the domestic and international markets after detecting the impurity, and initiated the measures of voluntary recall. As of July 23, Zhejiang Huahai Pharmaceutical has completed the recall of all raw materials in China.

　　In 2012 and 2013, the current process of raw materials of this enterprise was approved by the European Drug Administration (EMA) and the US Food and Drug Administration (FDA) respectively.

　　Since July 6th, National Medical Products Administration has maintained close communication and contact with the European Drug Administration and the US Food and Drug Administration, paid close attention to the announcements and trends of risk assessment issued by international regulatory agencies, and organized experts to carry out risk assessment.

　　According to the toxicological data, the maximum daily intake limit of N- nitrosodimethylamine is 0.1μ G, which is equivalent to the provisional reference limit value of 0.3ppm by the European Drug Administration (calculated by taking 320mg valsartan daily).

　　According to the above-mentioned limit value, National Medical Products Administration conducted risk investigation on all the seven domestic manufacturers of valsartan raw materials (including Zhejiang Huahai Pharmaceutical). Except for the impurity of N- nitrosodimethylamine in valsartan raw materials of Zhejiang Huahai Pharmaceutical, the impurity detection value of N- nitrosodimethylamine in other domestic manufacturers of valsartan raw materials was lower than the limit value or was not detected.

　　There are 6 pharmaceutical manufacturers involved in the use of valsartan in Zhejiang Huahai Pharmaceutical:

　　The valsartan capsule (National Medicine Zhunzi H20103521) produced by Hunan Qianjin Xiangjiang Pharmaceutical Co., Ltd. has not yet left the factory.

　　The impurities of N- nitrosodimethylamine in the listed products of the other five manufacturers exceeded the limit, namely

　　Valsartan Hydrochlorothiazide Capsule of Chongqing Kangkeer Pharmaceutical Co., Ltd. (National Medicine Zhunzi H20080097)

　　Valsartan dispersible tablets of Hainan Huanglong Pharmaceutical Co., Ltd. (National Medicine Zhunzi H20050508)

　　Valsartan dispersible tablets of Harbin Sanlian Pharmaceutical Co., Ltd. (National Medicine Zhunzi H20061058)

　　Valsartan Hydrochlorothiazide Dispersible Tablets of Jiangsu Wangao Pharmaceutical Co., Ltd. (National Medicine Zhunzi H20090262)

　　Valsartan dispersible tablets of Shandong Yijian Pharmaceutical Co., Ltd. (National Medicine Zhunzi H20090319)

　　The above five preparation manufacturers have stopped using the raw materials of Valsartan of Huahai Pharmaceutical and recalled relevant drugs according to regulations.

　　National Medical Products Administration has asked all provincial food and drug supervision and management departments to urge relevant preparation manufacturers to take recall measures, and disclose relevant recall information on the websites of five manufacturers, including the contact numbers of the enterprises responsible for the recall.

　　In order to facilitate the public to know in time whether the Valsartan drugs being used are within the scope of recall, five manufacturers have cooperated with information technology companies and launched the code scanning inquiry function at 22: 00 on July 26, 2018. The product traceability code can be scanned through the mobile APP to realize instant inquiry.

　　National Medical Products Administration spokesman stressed that besides the above five preparation manufacturers, other valsartan preparation products are not included in the recall.

　　At present, European Union and other multinational drug regulatory agencies believe that N- nitrosodimethylamine belongs to Class 2A carcinogen (that is, there is sufficient evidence in animal experiments, but the evidence is limited), and it may be exposed to this substance in daily life (such as preserved food). Analysis of the drugs involved this time will not cause serious health risks to patients, but for safety reasons, risk control measures such as stopping sales and recalling should be taken.

　　On July 27th, FDA issued a notice that patients taking recalled valsartan should continue to take the current drugs until doctors or pharmacists provide alternative drugs or different treatment schemes.

　　A spokesman for National Medical Products Administration reminded that patients who are taking valsartan drugs must not stop taking them without authorization, because the risk of stopping taking them without authorization is more direct and serious for patients with hypertension. Whether to stop taking medicine or change medicine must be carried out under the guidance of a doctor. You can contact a doctor to replace other drugs containing valsartan that are not involved in the recall or choose other drugs for alternative treatment.

　　National Medical Products Administration requires the relevant provincial food and drug supervision and management departments to continue to follow the relevant provisions of the Measures for the Administration of Drug Recall, urge enterprises to do a good job in product recall and protect people’s drug safety.

　　Xinhua News Agency, Beijing, July 17th Title: Answers written between green mountains and green waters — — Summary on the Effect of Ecological Environment Protection since the 18th CPC National Congress

　　Xinhua news agency reporter

　　Ecological prosperity leads to civilized prosperity. Entering a new era, the development of ecological civilization has become a compulsory question.

　　This is an answer sheet written between green mountains and green hills, and it is also an answer sheet written in the hearts of the people — —

　　Since the 18th National Congress of the Communist Party of China, under the guidance of the CPC Central Committee with the Supreme Leader as the core and under the scientific guidance of the Supreme Leader’s ecological civilization thought, the whole party and the people of the whole country have adhered to Lucid waters and lush mountains are invaluable assets’s idea, strengthened the ecological environment protection in all directions, regions and the whole process, and created an ecological miracle and a green development miracle that attracted worldwide attention.

　　The sky is bluer, the mountains are greener and the water is clearer: the people’s sense of acquisition, happiness and security has been significantly enhanced.

　　In midsummer, Yani National Wetland Park. Under the bright sunshine, the winding Niyang River is sparkling, and the sandbars in the river are full of green trees.

　　"The air is fresh and the environment is beautiful. It is very happy to live here." Yang Jiram, a villager living in Liding Village, Bayi District, Linzhi City, Tibet, who lives next to the wetland, lamented that it has changed a lot, and it is no longer a barren grass beach that dug sand and quarried stones many years ago.

　　A corner of Yani National Wetland Park (photo taken on April 7). Xinhua News Agency reporter Nie Yishe

　　At that time, there was little vegetation and serious desertification. Whenever there was a sandstorm, I couldn’t keep my eyes open. Until 2009, Linzhi City began to implement wetland protection and restoration projects, and surrounding villagers participated in sand prevention and afforestation, and the scenery here gradually changed.

　　The change of Yani Wetland is a vivid microcosm from the grassland beach to the park where birds prey on Fangzhou, which shows the solid pace of China’s continuous promotion of ecological environment protection in the new era.

　　Once upon a time, smog was frequent, dust was rampant, and rivers were black and smelly … … In 2012, China’s total economic output accounted for about 11.5% of the world, but its energy consumption per unit GDP was 2.5 times the world average. Development has reached a fork in the road that must be transformed.

　　Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has taken the construction of ecological civilization as an important content to promote the overall layout of the "five in one" and the coordinated promotion of the "four comprehensive" strategic layout, and has made unprecedented efforts to grasp the construction of ecological civilization. The 19th National Congress of the Communist Party of China listed "the tough battle against pollution" as one of the three tough battles to build a well-off society in an all-round way.

　　Implementing the decision-making and deployment of the CPC Central Committee, various localities and departments have adopted a series of practical measures to help fight the tough battle against pollution.

　　Comprehensively rectify scattered polluting enterprises and clusters and accelerate the elimination of backward production capacity; The construction of urban sewage pipe network has been rapidly promoted, and the sewage treatment capacity has been continuously improved; Clean heating transformation reduces loose coal pollution, and renewable energy develops rapidly … … The quality of China’s ecological environment has improved significantly.

　　The sky that was once shrouded in smog was gradually polished. In 2022, the proportion of days with excellent air quality in cities at prefecture level and above will reach 86.5%, and the proportion of days with heavy pollution will be reduced to less than 1% for the first time.

　　The quality of water environment has undergone a turning point. In 2022, the proportion of excellent sections of surface water quality in China rose to 87.9%.

　　More and more green is spreading in the mountains and rivers. China’s forest area and volume have achieved double growth. Exquisite street corner parks allow citizens to enjoy a better life in the "ecological blank".

　　A profound change in development mode: promoting the coordination and unity of economic and social development and ecological environment protection

　　Entering Yucun Village, Anji County, Zhejiang Province, the rolling mountains, flowing water and green bamboo have attracted countless tourists.

　　More than 20 years ago, due to the development of "stone economy", the mountains in Yucun became "bald light" and the water became "soy sauce soup". Yucun people, who have learned from their mistakes, have shut down mines and cement plants one after another to develop a "beautiful economy."

　　In August, 2005, the supreme leader, then secretary of Zhejiang Provincial Party Committee, visited Yucun, and after learning about Yucun’s practice, he evaluated "brilliant move" and put forward "Lucid waters and lush mountains are invaluable assets" clearly for the first time.

　　Since the 18th National Congress of the Communist Party of China, this concept has led to profound changes in the vast land of China.

　　Yibin, "the first city in the Yangtze River". Minjiang River and Jinsha River meet here.

　　Standing in Sanjiangkou and looking north, it used to be Yibin Riverside Industrial Zone within 5 kilometers. Yibin Tianyuan Chemical Plant, which was founded in 1943, was less than 100 meters away from the Yangtze River coastline.

　　Today, on the banks of the Yangtze River, the former factory building has turned into the Yangtze River Park. In the distance, the newly established Sanjiang New District is changing with each passing day. Tianyuan Chemical has extended its industry to new chemical materials and new energy battery materials and embarked on a new industrial track.

　　Through continuous exploration and practice, all localities have changed their development ideas, gradually embarked on a road of coordinating environmental protection with economic development, and made solid progress in green, circular and low-carbon development.

　　In order to better protect the environment, we will speed up the improvement of diversified ecological compensation mechanisms in many places, so that good mountains and rivers and good ecology will become "valuable treasures" for common protection.

　　Since the 18th National Congress of the Communist Party of China, China’s economic development and ecological environment protection have been more coordinated, and the space for green development has been further expanded.

　　While the quality of the ecological environment has obviously improved, the total economic output has jumped to 120 trillion yuan, and the per capita GDP has remained above 12,000 US dollars for two consecutive years.

　　Green indicates the future: strive to build the modernization of harmonious coexistence between man and nature

　　Not long ago, the staff of the Reserve Administration of Muling Forestry Bureau Co., Ltd., Longjiang Forest Industry Group, once again found a clear image of the wild Amur tiger "Wandashan No.1" in the forest area through the field infrared camera during routine patrol.

　　Rare wild animals and plants are full of vitality between green waters and green mountains. Behind this is China’s unremitting efforts to strengthen biodiversity protection and continuously promote the harmonious coexistence between man and nature.

　　Since the 18th National Congress of the Communist Party of China, a series of fundamental, pioneering and long-term green development systems have been solidly promoted — —

　　Major ecological projects such as the Three-North Shelterbelt and Natural Forest Protection have been further promoted. In the past 10 years, about 1.02 billion mu of afforestation has been completed in China, and the green map has been continuously expanded.

　　In the ten years to 2019, the area of desertification and desertified land in China decreased by 50,000 square kilometers and 43,300 square kilometers respectively. Xinjiang, as a province with the largest desertification and desertification area in China, has achieved "double reduction" of desertification and desertification land area for the first time.

　　The construction of a nature reserve system with national parks as the main body has been accelerated, and the construction of a national botanical garden system has taken important steps to jointly promote the formation of a relatively complete biodiversity protection system.

　　The first batch of national parks handed over eye-catching "transcripts": Sanjiangyuan National Park realized the overall protection of the sources of the Yangtze River, the Yellow River and the Lancang River; The Giant Panda National Park has opened 13 ecological corridors in giant panda areas, protecting more than 70% of wild giant pandas.

Special feature of 1905 film network When the opera meets the film, since its release, it has been evaluated with the high score of Douban 8.2 by virtue of the audience’s good reputation.

As the first 4K panoramic Cantonese opera film, it was shortlisted for the best opera film in the Golden Rooster Award for Chinese films, and also won the Golden Coconut Award for the best technology in Hainan Island International Film Festival. Through film technology, traditional Chinese opera is given a new look, and behind this, it is also inseparable from the credit of editing technology.

The editor of this film is a national first-class editor. His previous representative works include Youth Fight, Deep Sea Sword and Men’s Gang. Sun Yiqun’s mother is also an editor. She is Yang Xingyuan, the former president of China Film Editing Society, and her representative editing works are various.

Can editing technology be inherited? In this issue of Behind the Scene, Yang Xingyuan and Sun Yiqun, the editors, lead us into china national film museum to reveal the history of film film editing, and experience the technological changes of film editing together from the film age to the digital age.

Behind the scenes: Film editor Yang Xingyuan reveals the tools of "film film editing"

Film clip: "Manual sewing machine"

I have a particularly cordial feeling. I can feel the temperature of all these devices. Entering china national film museum, Yang Xingyuan knows a lot about the film editing machines in the museum.

　

Facing a splicing machine full of historical colors, Yang Xingyuan introduced that Premier Zhou Enlai cared about film splicing and specially entrusted Tianjin No.2 Optical Instrument Factory to develop this splicing machine for them, also known as the four-way sound painting machine.

From the end of the 1960s to the end of the 1990s, this was the only tool for their editors, and the frequency was controlled in the frequency of 24 squares by hand. "My editing of Man to Middle Age, Zhou Enlai and Armageddon was cut out by such a machine."

The process of film editing is particularly complicated. After the film is finished, it should be washed in the studio, and then printed into samples with the negative, and the editor and the director and other producers will jointly review it.

　

When editing, the sound and picture of the sample should be synchronized with the negative, so the first step of editing is not to cut, but to arrange, and each of the specific scenes, shots and sound tapes in all the shooting materials should be completely recorded first, otherwise the material synchronized with the negative can not be found later.

　

"So it’s not easy to start editing. All this work has to be done before you can enter the creative stage." Yang Xingyuan said that it is more difficult at the stage of revision. For example, if there are ten films and one place is revised, these ten films will have to be hand-cranked from beginning to end on the film receiver. "After shaking it down, it is a lot of films, and then it is lifted one by one. At that time, the state positioned the editor as a light manual worker. "

Recalling the editing work of "Zhou Enlai", at that time, the version of mixed editing of picture and sound was completed, but the director had to modify the picture temporarily. "I was so angry that I wouldn’t change it for you, but he personally took a dozen films upstairs and asked me to change it." In order to make the film better, Yang Xingyuan said that even if the editing process was not easy at that time, it still had to be modified.

In the past, when editing technology was underdeveloped, a small machine supported the creation of many excellent classic films. Sun Yiqun recalled, "At that time, my mother stayed up late at night, so I slept next to her with a small quilt. I always wanted to shake this film, and my mother was particularly afraid that I would destroy it. She said that if you broke it, the consequences would be unimaginable."

Nowadays, computer technology is very simple to operate the effects of transition editing, such as fade-in, fade-out, cut-in and cut-out, overlapping, etc., but it is very troublesome in the film age. It is necessary for the editor to make specific marks on the film with a special pen, and then let the special effects producers use optical skills to make them on the film.

　

The complicated and exquisite technology of film film editors bears the heavy history of China films.

"For example, there are seven kinds of scenes to record a dialogue and an action now. I think the workload is very heavy. There are more than 200 shots as soon as I open the folder, but it is much more complicated than us to hear these things that the predecessors are editing. My mother sewed by hand at that time, and now it is equivalent to using an electric sewing machine. "

　

Hearing his mother’s introduction to film editing technology, Sun Yiqun felt a lot. "Now we have mastered new technologies and brought us convenience, while the older generation got through it like that and admired it."

Digital editing: White Snake’s secret recipe

The era of film editing has ended, and digital computer technology has been fully popularized. Nowadays, Sun Yiqun’s editing work is no longer just a simple operation technology, but also needs to integrate his own ideas at the creative level.

　

Talking about her latest film White Snake, Sun Yiqun said that in editing skills, she paid special attention to the balance between drama and film.

"There are many stylized things in traditional Chinese opera. Actors often communicate with the audience and the camera, which breaks the spatial illusion that the film has carefully established." Therefore, she will especially avoid editing the lens that highlights the "fourth wall" and choose more pictures of actors communicating with each other.

　

When the traditional Chinese opera performance is put on the movie screen, it is easy to have a magnifying effect. In addition, it is 4K quality, and any tiny expression of the actor can be clearly captured. When editing, Sun Yiqun will also avoid the scenes that will appear exaggerated on the big screen.

"The hand, eye, body and steps of an opera actor, his figure is a very important aspect of expression. If I edit excessively or even choose inappropriate scenery, it will destroy the good rhythm of the opera, so I still have to pick up its rhythm and grasp it well." How to find a moderate point is a difficult part of this editing.

　

Sun Yiqun is also worried that if the aria is too long, it will affect the audience’s desire to watch. Among them, there is a scene of "Broken Bridge and Residual Snow", in which lady white snake complains to Xu Xian after suffering, and the recorded aria is very long. She took the initiative to discuss the reduction with the director. "Otherwise, it would ruin lady white snake’s image and become a dissatisfied housewife." Finally, after coordination and careful cutting, it was cut for more than 30 minutes.

White Snake reinterprets classic stories and boldly tries new editing techniques of combining drama with film. Yang Xingyuan feels that today’s editors have a higher pursuit than the older generation. "They need to have the ability to master the lens and handle the structure, not the things we have learned. Those things have passed. They can put more energy into creation. "

Two generations of editing methods

Yang Xingyuan was originally an actor, but later transferred to Changying and changed to editing. "Having been an actor for more than ten or twenty years, I can still understand the performance and rhythm, and this accumulation will be useful. I just thought I could learn to edit and play my little role."

　

Thanks to her experience as an actor, Yang Xingyuan switched to editing, and she can better handle the rhythm of performances and shots.

　

When cutting "Man to Middle Age", because Lu Wenting and Yang Xingyuan are both of the same generation, Yang Xingyuan said that she edited the character completely according to the character and her own feelings. "Lu Wenting went to see the child, and the editor must understand how she looked at it in order to impress the audience. So I chose her to post it in the nearest place to watch the child sleeping, so that I can understand the psychological feelings of this character. "

With more than 40 years of experience in behind-the-scenes editing, Yang Xingyuan concluded that editors should think about editing from three angles.

　

The first is the director. "I must know what he wants to do, what he wants to show and what he wants to give to the audience." Then there is the character, "to understand the character’s mentality and his various things."

Then there is the audience. "You must know what the audience wants to see and where his interest lies. I can’t say that I am an old lady now. My rhythm is slow, so I don’t appreciate the audience’s appreciation ability. I also deal with the film according to my rhythm and speed, and the audience will definitely stop watching it. "

Daughter Sun Yiqun did a lot of work that had nothing to do with art. Later, her mother thought she should learn a skill, so she taught her to edit and took her into the business. The two later jointly edited the TV series Behind the Vanity.

　

"They always ask why the play they cut is not good-looking. I said that because you cut the process, it is not a play." Sun Yiqun believes that a good editing is to "pick up" the scene and find the eye of the scene, while a bad editing is to exert an average force. "If the scene and the scene are not more energetic, it will not work."

　

In her view, editing and scriptwriting have a lot in common, they all want to tell stories, and they all want to think about how to make this story vivid, interesting and arresting.

From Yang Xingyuan to Sun Yiqun, from film editing to digital editing, the editors of mother and daughter have great enthusiasm for this art, which has been passed down from generation to generation not only for the iterative upgrade of film editing skills, but also for the consistent dedication, concentration, lean and innovative craftsmanship as editors.

　　Yesterday, Jiangsu Education Examinations Institute held an open day for marking the college entrance examination. Yangzi Evening News reporter and 12 candidates and parents’ representatives from Nanjing came to the marking site of the college entrance examination, visited the answer sheet storage group, scanning group and Chinese subject marking group successively, and got in touch with the marking work of the college entrance examination at zero distance, feeling the fair, just, rigorous and orderly working atmosphere of the marking of the college entrance examination.

　　site

　　The electronic image of each candidate’s answer sheet is kept for 4 years.

　　At the examination paper scanning point of the Provincial Education Examinations Institute, the staff are busy unpacking and scanning the examination paper, storing the information in the warehouse, and scanning it through a high-speed special scanner, cutting the contents of the examination paper into pictures, encrypting the candidates’ names, admission ticket numbers and other information, and sending them directly to each marking point through special optical fiber.

　　Fu Yaozhang, director of the Network Information Center of the Provincial Education Examinations Institute, said, "The scanning number of all answer sheets in all subjects must be consistent with the data of candidates participating in the arrangement, and the electronic image of each candidate’s answer sheet should be kept for 4 years."

　　As in previous years, this year, all subjects of the college entrance examination in our province will continue to carry out computer-aided online marking, and the Provincial Education Examinations Institute will undertake the scanning of answer sheets and the marking of multiple-choice questions. For non-multiple-choice questions, the marking of Chinese, mathematics and foreign languages will be handled by Nanjing Normal University, and the marking of six selected subjects and small languages will be handled by Nanjing University.

　　Wu Renlin, vice president of the Provincial Education Examinations Institute, said that there were more than 2,200 marking teachers this year, all of whom were selected from the database of marking teachers in the province. Among them, the marking teachers who mark the test questions with large scores and strong subjectivity, such as composition questions, discussion questions, calculation and solution questions, experiments, etc., all have more than 3 years of teaching and research experience and some marking experience.

　　"Four-evaluation system" makes marking more fair

　　The marking method is also particular: the "four-evaluation system" is implemented in the non-multiple-choice part of all subjects. "After the test paper is scanned and entered into the computer, it will be cut into several blocks. After cutting, the computer will automatically process all the blocks with secret numbers. All the secret numbers correspond to the candidates one by one, but the marking teacher can’t see any identity information of the candidates, and no one can change the answer sheets after secret number processing, which can ensure the fairness and justice of marking work." Wu Renlin said that each marking group marked the cut blocks separately, and each block was randomly distributed to two different marking teachers for independent marking. If the scores scored by the two people are within the scoring threshold set by the subject marking expert group, the average of the scores scored by the two people is taken; If it exceeds the scoring threshold, it will be submitted to the third marking teacher for three evaluations; If it still exceeds the scoring threshold, it will be submitted to the fourth marking teacher for four evaluations. The difficult problems encountered in the marking process are collectively discussed and solved by the marking expert group.

　　Marking progress

　　Chinese: the score of the test questions is accurate to 1 point.

　　Professor Cao, a member of the Chinese marking group of the college entrance examination, introduced that this year’s marking was more orderly, rigorous, scientific and stable. On the second day after the end of the college entrance examination, marking experts entered the marking site to prepare for marking. At present, the scores of most topics are accurate to 1 point, ensuring that the hard work of each candidate is properly reflected.

　　Professor Cao said that the marking of Chinese in the college entrance examination has maintained a steady and progressive trend. "This year, the Chinese in the college entrance examination is generally stable. From the results of the trial evaluation, it is easier for candidates to get started, and their thoughts and feelings can be expressed, and the degree of discrimination in the test papers is ideal. For the composition evaluation that candidates and parents care about, we will focus on correcting the phenomenon of high scores and low scores in the process of marking and correcting ‘ False and wrong cases ’ Strictly check the excellent composition and carefully identify the fake phenomenon of low scores and high scores. In addition, the team leader and the staff of the expert group will repeatedly check without any dead ends, and organize the verification team to conduct spot checks on the composition marking. "

　　Mathematics: More than 8 solutions have been prepared for each problem such as function.

　　The math marking team for college entrance examination consists of math teachers from NTU and NTU and more than 80 middle school teachers. Professor Yan, a member of the math marking group and professor of Nanjing Normal University, introduced that the math marking group organized a subject expert group and each topic leader to investigate the answers of the province’s math test papers, and learned about the possible answers of candidates through full investigation. "The expert group has been carefully formulating the scoring rules. For example, function problems and many big problems have provided more than eight solutions, so it is necessary to formulate scientific evaluation criteria. Decompose each solution into knowledge points, and ensure that homogeneous knowledge points give the same scores and fair standards. Once a new solution is found, the marking teacher must report to the subject expert group in time, and then the experts will discuss and study the scoring rules of this solution, and they are not allowed to evaluate it privately. "

　　Professor Yan revealed that the mathematics marking of the college entrance examination should be completed before the 20th.

　　English: enrich the grading rules and take care of a variety of reasonable composition viewpoints and angles.

　　Professor Shao, a member of the English marking group, introduced that the expert group carefully analyzed the characteristics and reference answers of "task-based reading" and "written expression" and refined the evaluation criteria; The writing points and sub-points of the composition part are subdivided. At the same time, through a large number of sample papers covering various regions and examination rooms, starting from the actual situation of candidates’ answers, the scoring rules are enriched and a variety of reasonable composition viewpoints and angles are taken care of.

　　English marking implements a three-level quality monitoring system of subject expert group, marking team leader and team members. Each paper has been reviewed by team members for multiple rounds back to back, arbitrated or spot-checked by team leader, and monitored and spot-checked by experts. At the same time, the online marking system and monitoring system have a clear division of labor. According to the characteristics of English subjects, the software is designed scientifically and matched reasonably, and equipped with real-time marking, quality statistics, bad error monitoring and early warning systems to avoid misjudgment as much as possible.
