The combined investigation team formed the investigation and
On the 3rd, the Lishui County Education and Sports Bureau issued a preliminary investigation report on the issue. The report stated that the Lishui County teachers recruited written test propositions all entrusted to third parties. According to the relevant regulations of the examination work, the current examination The work is still in a closed period. Except for the reviewers, other personnel are temporarily unable to contact the test papers. After the closure period, the test papers will be identified and the results will be announced in time. In response to the 2019 annual report of the teachers' language test papers in Lishui County and the set of college entrance examination simulated test papers in Jining City, Lishui County has established a joint organization of county disciplinary committees, editors, public security, personnel, education and other departments. The investigation team conducted a comprehensive investigation of the problems reflected on the Internet. At present, it has been found that the teacher's recruitment language written test on June 1st was seriously misunderstood due to the work of the third-party propositional agency outside the city, which led to the similarity between the Chinese pen test paper and the set of college entrance examination mock papers in Jining City. The study decided:
1. Re-organize the written test for the 2019 Lishui County public institutions to recruit teachers' language examinations, and exempt the examination fees. 2. Seriously handle the relevant responsible persons and third-party propositions in accordance with the law, and investigate and deal with other issues reflected on the Internet. 3. Apologize for the inconvenience caused to the candidates. The specific examination time will be announced separately and will be published on the website of the People's Government of Lishui County. As the summer has arrived, the crayfish has once again become a "explosive" food item. Behind the blaze, the price of crayfish has become a hot topic this year, and many consumers feel that the price is very close to the people. Behind this, on the one hand, the price fluctuations of crayfish, and on the other hand, the surge in crayfish farming.
In 2017, the total social and economic output value of crayfish in the country was about 268.5 billion yuan, an increase of 83.15% over 2016. Such a large and high-growth market has driven the rapid expansion of crayfish farming across the country and the competitive positioning of the capitalists on the crayfish industry chain. However, the industry analysis shows that the extensive and small-scale farming of crayfish industry is still the mainstream, and the cultivation of the integrated management of “nurturing, adding and selling” should be increased.
The price of diving is “cheap, this year is much cheaper.” On June 3, the Beijing News reporter came to the wholesale market of agricultural and sideline products in Jinxiu District, Haidian District, Beijing. Many fishery stall merchants described the price of crayfish as “cabbage price” this year. "In the past, like this two or two, I have to sell 60 yuan a pound, now only 35 yuan a pound, these days have fallen again." A merchant said that compared to the previous two years, this year's crayfish prices Very low, the source purchase price has dropped a lot.
The Beijing News reporter found that according to the quality and weight of crayfish, the price is different. The lowest price is 18 yuan / kg, the highest price is 35 yuan / kg, the common price is 25 yuan / kg. According to the data of the China Shrimp Valley Network, which was built by Hubei Shrimp Valley E-commerce, Qianjiang Sijiyou Agricultural Products Market and Qianjiang City Lobster Association, the live lobster price is 10.5 yuan - 32 yuan / kg. The crayfish price network data shows that since May 4th, the national average price of crayfish (7-9 money) crayfish has a little fluctuation, but the overall downward trend has dropped from 31.71 yuan / kg to June. 20.25 yuan / kg on the 3rd.
On the e-commerce platform, the price of crayfish is also relatively close to the people. For example, Box Ma Xiansheng launched a promotional price of 100 yuan and 3 pounds for the traditional spicy and thirteen flavors this year. The daily fresh food is also available for bag-opening. 99 yuan 3 boxes (750g × 3) of the "explosive material Ma Xiao". On the Jingdong platform, on June 3, the Beijing News reporter found that a franchise store with a sales volume of “Red Gongfu” launched “the average price of 2 copies of 59.9 yuan, 3.6 kg 35-50 per box. "The activity, converted to only 16.6 yuan / kg, 1.2-1.7 yuan / only. At the same time, Tmall went to a franchise store with a sales volume of “Red Kitchen”, which also launched “2 average price of 59.9 yuan, 34-50 each”. The data shows that its monthly sales are more than 150,000.
At the restaurant terminal, the price of spicy crayfish is also very attractive compared to previous years. The Beijing News reporter found through the retrieval of the take-out platform, in the Wangjing small waist (Colorful City flagship store), a spicy crayfish for 68 yuan, about 8-10. And the spicy temptation · Ma Xiao (Shangdi shop) "Spicy crayfish 嗨 enjoy the money" hit 50% off 129 yuan, 12 per box. According to the store to buy one get one free, that is, 129 yuan 24. The spicy crayfish of the Xiaoshizao Restaurant, which specializes in the E-food, is only 88 yuan.
Why is the current price of crayfish falling? "There are more farmers, and now the crayfish are on the market, and the supply is sufficient." A crayfish farmer from Qianjiang, Hubei Province, an important production area of crayfish analyzed, "But the price is one price per day, depending on the market." The current situation is also a reflection of seasonal fluctuations in crayfish prices. Yin Hao, secretary-general of the Hubei Shrimp and Rice Association, told the media that the price of crayfish will show a V-shaped trend every year, that is, the price will gradually decline from the beginning of the year, and will fall to a low point in May, and then gradually rise up.
The scale of farming has soared in the downturn in crayfish prices. In addition to the seasonal impact, industry analysts analyzed another reason for the surge in aquaculture area and thus increased production. In the main production areas of crayfish such as Hubei and Hunan, the aquaculture area has expanded significantly. In the whole country, crayfish have also been cultivated in Gansu and Xinjiang in the northwest. According to the China Crayfish Industry Development Report (2018) prepared by the Agriculture and Fisheries Administration of the Ministry of Agriculture and Rural Affairs and the National Aquatic Technology Extension Station and the Chinese Fisheries Association, the national crayfish farming area reached 12 million mu in 2017, compared with 2016. An increase of 3 million mu has increased by 30%.
At the same time, in 2017, the total production of crayfish farming in the country was 1,219,700 tons, an increase of 20.41% compared with 8.991 million tons in 2016. The production of crayfish in Hubei, Anhui, Hunan, Jiangsu and Jiangxi provinces accounted for 96.91% of the country's total output, of which Hubei Province had the largest output, accounting for 55.91% of the country. In 2017, the total social and economic output value of crayfish in the country was about 268.5 billion yuan, an increase of 83.15% over 2016. Among them, the output value of the aquaculture industry is about 48.5 billion yuan.
Taking Jiangsu as an example, in 2017, the area of crayfish farming in Jiangsu Province was 1.382 million mu, which was an increase of 759,000 mu compared with the same period in 2016, an increase of 121.83%. The lobster industry white paper released by Minxian County in Jiangsu Province on May 22 shows that the total economic output value of lobster industry in the year of 2018 reached 13.941 billion yuan. At present, the area of crayfish farming in the county is 8000,800 mu, an increase of 311,000 mu from the previous year. The annual production of crayfish reached 80,500 tons, compared with 35,100 tons in the previous year.
In the wholesale market of agricultural and sideline products in Jinxiu, a small direct selling stall merchant from the origin of crayfish said that its products came from farmers in Jiangsu Province and sold straight. “There are more local crayfish, and every household is raising. The main market is also consumed. Although there are certain risks, it can still make money.” At the same time, the crayfish industry attracts capital. The Beijing News reporter found that from 2016 to 2019, at least six crayfish entrepreneurial star projects appeared.
In April 2016, “Prawns Came” won 58 rounds of A-share financing of 58 million yuan, which was previously approved by Fengyun Angel Fund for nearly 10 million yuan in angel financing. In July 2017, Xinliangdao's supply chain brand Xinliangji announced that it had received 120 million yuan A+ round financing from Zhongding Ventures and Ruifeng Capital. In August 2017, the hot life incubated by the Spicy Temptation Group completed a B round of financing of 140 million yuan, and the hot life has the crayfish brand “Ma Xiao”. In June 2018, the “Shrimp Emperor” restaurant in Qianjiang, Hubei Province received 30 million yuan in financing.
In February of this year, the “Shrimp Brand” received a million-dollar angel round of financing, and its innovative launch of crayfish sandwiches. In March of this year, Humboldt completed the B round of financing. By the end of 2018, Humboldt’s “Falling Shrimp” brand nationwide stores had opened more than 1,000 stores nationwide. The crayfish heat continues to make crayfish a “net red” food. In addition to attracting food and beverages in its own taste, it also has the merits of marketing and promotion of various origins that rely on the crayfish economy. Various production areas have held various activities such as crayfish festival, shrimp king competition, food evaluation meeting, etc., which will promote the consumption of crayfish and the development of surrounding industries. According to incomplete statistics, more than 90 million people participated in the 2017 crayfish festival.
This year is no exception. For example, Jixian County first held the Dragon Year Lobster Festival in 2000 to create the signs of “Crawfish Lobster” and “Lobster Festival”. Hunan Nanxian, the “three strong” of the crayfish industry, invited more than 200 net red anchors on May 28 to show the “daily” of crayfish to nearly 10 million fans.
At the same time of introduction, it is more necessary to go out. The important driving force for crayfish to go out is the e-commerce platform. Through the e-commerce business model, crayfish can easily go to the national market and benefit the production areas. In 2017, the transaction volume of e-commerce platform in Hubei Province alone reached 500 million yuan, including the “Internet + Crayfish” operation mode of Qiangang’s “Shrimp Valley 360” vertical e-commerce platform, attracting more than 300 large purchasers and dealers. Home, crayfish logistics and distribution of more than 300 cities across the country, more than 3,000 customer terminals, crayfish annual transaction amounted to 359 million yuan.
Intensive industrialization needs to be raised in the upstream breeding end of crayfish, and the major e-commerce platforms are even more staking, competing for market share. At the beginning of March this year, Suning Fresh and Suning purchased a strategic cooperation agreement with the Jingzhou Municipal Government of Hubei Province for a year of 300 million yuan to plan the establishment of a 4,000-acre crayfish cooperation base. In the summer of 2018, Suning Supermarket contracted 1000 acres of crayfish shrimp fields in Hubei, live shrimp firing, direct supply of origin, directly increased to 4,000 acres this year.
At the end of April this year, Daily Youxian also signed a contract with Hubei Qianjiang Liuwu Aquatic Products and Hubei Honghu Xinhongye Food Strategy to expand the direct mining base to Qianjiang and Honghu. At the same time, the logistics industry has used their own advantages to enter the game. In May, Zhongtong Commercial and Hubei Grain and Oil Ecological Agriculture Company held a cooperation negotiation on the cooperation of crayfish supply chain. Zhongtong Commercial said it will open its own social channels to operate crayfish items. In addition, logistics companies such as SF Express and Post have already started the crayfish single product business.
Although the crayfish industry is hot, the China Crayfish Industry Development Report (2018) analyzes that the current crayfish industry is not organized and intensive. Extensive farming and small-scale farming are still mainstream, lacking uniform production. Norms and standards limit industrial competitiveness, industrialization, and risk resistance. Organizations such as industry associations, large-scale cooperatives, and leading enterprises are not sufficiently cultivated, and the number of organizations is not obvious enough. The cultivation of the integrated management of “nurturing, adding and selling” should also be strengthened, and the integration of the first, second and third industries needs to be improved. Recently, US President Trump announced at the Yokosuka Naval Base's Hornets amphibious assault ship that he will issue an order to change the electromagnetic catapult on the aircraft carrier to a steam catapult. This remark continues Trump's consistent maverick style, which has surprised many observers and military commentators. So, is the electromagnetic ejection system really as uncomfortable as Trump said, will it be re-invaded by steam? This article tries to do the analysis.
The public reasons for Trump's sinister electromagnetic ejection system mainly come down to two points: First, the price of the electromagnetic ejection system is too expensive, the United States has already paid for it 900 million US dollars, and the price is not mature, the steam ejection system is high, which makes the habit of planning Trump, a businessman-born Trump is unbearable; second, the reliability is low. Since the Ford aircraft carrier was in service, the size of the aircraft has been continually faulty. The failure of the electromagnetic ejection system is more prominent, and the aircraft ejection efficiency is not ideal, with an average of 240 shots per shot. A fault will occur on the left and right. This data is really not bright, and it has already affected the Ford service plan. From a deeper perspective, there is another possibility that the United States intends to release "smoke bombs."
The United States is the most technologically intensive country in the world, and the country most sensitive to building technical barriers and maintaining its technological advantages. When the United States finds that other countries have gradually approached their leading technology fields, most of them will try their best to sing the technology to achieve the goal of “biasing” the opponent. In the 1960s, when the Soviet Navy was inconsistent between the development of nuclear submarines and professional aircraft carriers, the United States successfully suppressed the research and development plan of the Soviet professional aircraft carrier by vigorously advocating the uselessness of the aircraft carrier, so that the Soviet Navy only equipped a batch of chicken-like " Carrier cruisers such as Moscow and Kiev were not equipped with large-scale projectiles of true significance until the collapse of the Soviet Union. At present, in the field of electromagnetic ejection, the technical advantage of the United States has been difficult to maintain for too long. It is also very likely that the anesthesia opponent will give up the pace of catching up to achieve its own purpose and further consolidate the advantages of electromagnetic ejection technology.
In fact, compared with the steam ejection system, the electromagnetic ejection system has made great progress and is the best choice for large naval aircraft carriers in the future. Its technical advantages are very obvious, mainly reflected in the following aspects. Small size and light weight. The traditional steam ejection device has a complicated structure and requires many large gas storage tanks, occupying a large amount of hull space. The electromagnetic ejection device is smaller overall and does not require gas storage, saving nearly half of the space for other functions. At the same time, it weighs half as much as the steam catapult. In addition, the simpler structure also reduces the number of maintenance personnel and the intensity of work.
No water, very worry. Steam ejection devices require a lot of water vapor and must use fresh water. Although the seawater desalination ability of the aircraft carrier is very strong and can meet the ejection requirements, it is objectively necessary to ensure the volume and power of the seawater desalination device. The electromagnetic ejection device mainly relies on electromagnetic force ejection, no need for fresh water, which is undoubtedly a boon for naval vessels.
Wide elasticity and high precision. Thanks to the electric energy drive, the ejection power of the electromagnetic ejection device can be precisely adjusted by controlling the current. Up to 30 to 40 tons of heavy-duty carrier aircraft, early warning aircraft, down to several tons of drones can be easily ejected and started quickly. The acceleration is very smooth and uniform, which not only has higher energy utilization efficiency, but also reduces the structural strength requirements of the carrier.
Of course, there is no perfect technology in the world, and there are some short plates in the electromagnetic ejection. For example, its technical intensity is much higher than that of steam ejection, which inevitably leads to a problem of reduced reliability, which is a basic law; and it relies heavily on electricity and requires a powerful power generation and energy storage system. This pair of warships has relatively high requirements for power generation and control, and it is difficult for small and medium-sized conventional power carriers to bear; in addition, it will generate relatively strong electromagnetic radiation, which will interfere with the operation of the ship's electronic equipment. However, compared with the advantages of electromagnetic ejection, these shortcomings do not hide.
