Trump forced Japan to buy agricultural products in large quantities? Dissatisfaction with Japanese agricultural circles: excessive

  [Guo Weimin, special correspondent of Global Times in Japan, Sun Xiuping] Exports to China have decreased, and the United States has asked Japan to pay for it? Japan’s Kyodo News reported on the 14th that US President Trump asked Japan to buy "a huge amount" of American agricultural products, which aroused the vigilance of the Japanese government and the dissatisfaction of the agricultural sector.

  Kyodo News quoted Japanese and American government sources as saying that Trump had directly asked Japanese Prime Minister Shinzo Abe to buy American agricultural products, and also specifically pointed out the varieties that Japan needed to buy, including soybeans and wheat. The report emphasizes that this is an additional purchase requirement, which is different from the Japan-US trade negotiation framework being promoted by the US government with the goal of reducing the trade deficit with Japan.

  Japan’s Tokyo TV reported on the 14th that Japan-US trade consultations were held in Washington on Tuesday and Wednesday, mainly focusing on agricultural products and automobile tariffs of the two countries. When Trump met with Abe in the first half of this year, he asked the Japanese government to cut taxes on American agricultural products. According to data released by Japan’s Ministry of Agriculture, Forestry and Fisheries, from January to June this year, Japan’s agricultural exports decreased significantly compared with last year. In this context, the Japanese government must vigorously promote the export of agricultural products, so it is necessary to avoid making too many concessions to the United States in Japan-US trade negotiations in any case.

  Kyodo News said that the Japanese government is wary of the negative impact of this incident on trade negotiations and is fully discussing countermeasures. One of the measures may include buying American agricultural products under the framework of food aid to Africa. Kyodo News issued a document on the morning of the 14th, saying that the Japanese agricultural sector was puzzled and wary of the request of the US government. "This is an excessive demand when Japan-US trade negotiations are being promoted." An agricultural related person expressed indignation. The article said that if Abe’s government does not refuse the request of the United States, it may lead to a further strong rebound in the agricultural sector. However, Kyodo News deleted relevant articles in the afternoon.

  "Trump received an unusually high-standard reception when he visited Japan last time, in exchange for buying huge amounts of American agricultural products?" Japan’s "litera" news network commented that Abe’s government is "careful" to Trump, but for Trump, Abe is just a "servant" who listens to everything. Trump also imitated Abe’s accent a few days ago, recalling some of their past conversations on trade tariffs, and even ridiculed Abe’s father for being a death squad pilot. The article said that in order to force Japan to make concessions on issues including lowering tariffs, Trump would not hesitate to shake the foundation of the Japan-US alliance and put pressure on Tokyo. Munei Dengying, an economist at Nomura Research Institute, believes that the United States may require Japan to reduce tariffs and expand imports. The Japan-US trade agreement, which was supposed to be basically agreed at the end of September, suddenly became more unpredictable.

They are all tough characters! Count the brands of Volkswagen Group

  As we all know, it is a giant enterprise in the automobile industry in the world today, with 12 well-known automobile brands, and its sales volume ranked among the top three in the world in 2010. Behind all these shining titles, audi ag has experienced numerous interests struggles and countless money baptisms. If these Volkswagen-owned car brands are like brave soldiers, then the Volkswagen Group is undoubtedly the "commander in chief" who is strategizing and winning thousands of miles away. Today, this article will let the editor take you into the Volkswagen family, travel to that era, feel the interests you come and go together, spend money like water, and count the anecdotes of Volkswagen Group and its brands for you.

● Background introduction of audi ag.

Home of the car

  Audi ag was founded in 1937, and the company is headquartered in Wolfsburg, Germany, mainly engaged in automobile manufacturing and sales. At present, Volkswagen Group is the largest enterprise in Germany, and in 2010, it became the world’s largest car company with the largest sales volume, ranking 12th among the world’s top 500 companies. Volkswagen has factories in many countries around the world, and currently employs more than 500,000 people.

● The top 12 brands of German audi ag:

  I believe that many netizens are familiar with the background of Volkswagen. However, before starting this article, please allow me to say one more word. Let’s first get to know the 12 brands owned by audi ag, namely: Volkswagen,,,,,, Scania, Volkswagen Commercial Vehicle,, MAN and the newly acquired motorcycle brand Ducati. The editor of this article will start with the brand battle between Volkswagen and Porsche, and give you a brief introduction of five brands acquired by Volkswagen and their stories with Volkswagen.

● This is the same root, why is it too urgent to fry! -Volkswagen Porsche’s 80-year-old feud.

Home of the car

  For example, if I want to describe the relationship between Volkswagen and Porsche, I really can only think of the words "What’s the hurry?". After more than 80 years of feud and entanglement, the two giant brands have experienced countless undercurrent struggles for interests, and finally the "war" has come to an end temporarily after Volkswagen’s counterattack. For the story between them, let’s start from the beginning and tell you in detail the grievances between Volkswagen and Porsche.

Home of the car

  Speaking of the relationship between Volkswagen and Porsche, we have to mention an old man, that is, ferdinand porsche, the founder of Porsche and Volkswagen. The founding of Volkswagen was also closely related to Adolf Hitler, the leader of Nazi organization in Germany at that time. It was Hitler’s idea of producing a Volkswagen that only sold 990 marks in 1936 that made the world’s leading car established today. At that time, ferdinand porsche was a famous German automobile designer. He was ordered to lead a group of laborers to start the production of this kind of cheap car, and in 1937, he established "Gesellschaft zur Vorbereitung des Deutsches Volkswagen MBH" (Volkswagen Company).

Home of the car

  At this point, you may feel strange. Isn’t this ferdinand porsche the founder of Porsche? How did you get involved with the public again? Indeed, ferdinand porsche established the Porsche brand as early as 1931. At that time, Volkswagen was just a cheap car brand that he was "ordered to build" according to the requirements of Hitler’s Nazi government. It can be said that since the day Volkswagen was established, it was destined to be inextricably linked with Porsche.

Home of the car

  Let’s take a look at some genealogies of the Porsche family, and we will know how close Porsche is to the Volkswagen family. First of all, ferdinand porsche’s son Ferry Porsche and grandson Wolfgang Porsche have been running Porsche Automobile Company. Wolfgang Porsche is still the owner of Porsche Automobile, while his daughter Louis Piech and grandson ferdinand piech are in charge of Volkswagen. ferdinand porsche gave 62% of the shares of these two companies to his son Ferry Porsche before his death, and the remaining 38% was owned by his daughter Louis Piech. This is self-evident.

Home of the car

  It stands to reason that no matter how the equity is distributed, Porsche and Piech, who are both the heads of automobile companies and the same family, should have lived in peace. Moreover, the market positioning of Porsche and Volkswagen is quite different, and the direct competition relationship is very small. However, the aggressive personality of ferdinand porsche’s descendants determines that there will be a "blood shed" between Volkswagen and Porsche.

Home of the car

  In the early days of Volkswagen’s establishment, the two companies used to be "brother enterprises" of mutual benefit and exchange of needed goods. Porsche Model 64 produced in 1938 used many spare parts from Volkswagen. In 1969, Volkswagen and Porsche jointly launched VW-Porsche914 and 914-6 models, which were named 914 because this model was equipped with a four-cylinder from Volkswagen, while 914-6 was equipped with a six-cylinder engine from Porsche, showing the close relationship between Volkswagen and Porsche.

Home of the car

  However, the good times didn’t last long. With the death of ferdinand porsche and the continuous development of Volkswagen, Porsche has been completely surpassed by Volkswagen in terms of its share of the global automobile market and actual book revenue, and this momentum has quickly become a reality. Some "jealous" Wolfgang Porsche set his eyes on his "brothers" in the late 1990s.

  In 2004, the Porsche family, whose eyes were locked on Volkswagen, finally ushered in the best acquisition opportunity in theory. In this year, Volkswagen sold a large number of shares because of poor management and high production costs, and went to the brink of bankruptcy. According to statistics, the average wage of Volkswagen’s workers was the highest in Germany, but the production efficiency was the lowest. More than 40% of the factories closed down, and the economy was even more unable to make ends meet.

  Previously, the German government issued a law to prevent audi ag from being acquired by overseas investors, which expressly stipulated that when it comes to major issues such as company acquisition, it needs more than 80% of the support votes to pass, which means that Saxony will always have the veto power over public acquisition, and it is impossible for other companies to intervene in the public. This law is called "The Law of the People", and there are still many controversies today because of its strong local protectionism.

Home of the car

  Although the "Volkswagen Law" has blocked it, the Porsche family will never miss this excellent opportunity. First, they quietly acquired the shares of Volkswagen in the secondary market. By the first half of 2005, Porsche had held nearly 20% of the shares in audi ag. However, Porsche’s erosion of Volkswagen’s shares did not attract people’s attention during this period. Until October 7, 2005, Porsche suddenly announced that it would buy 8.27% of Volkswagen’s shares from institutional investors. At this time, Porsche has held 27.4% of Volkswagen’s shares, becoming the largest shareholder of Volkswagen in the world. Since then, Porsche has increased its shareholding in Volkswagen to 31% in March 2007. However, due to the existence of the Volkswagen Law, Porsche spokesman Bowman made it clear that this action is only a simple increase, and there is no intention of any acquisition.

Home of the car

  At this time, Porsche has become the heart of Si Mazhao, and everyone knows that the so-called "no acquisition intention" is just an excuse to hide the ear. In November 2007, the European Court of Justice proposed to abolish the Volkswagen Law. Porsche welcomed it and said that there was no plan to increase its shareholding. However, this duplicity only lasted for half a year. By 2009, the Porsche family had quietly increased its shareholding in Volkswagen to more than 50%.

  Subsequently, Porsche applied for anti-monopoly investigation. On July 23, 2008, the European Commission approved Porsche to acquire Volkswagen. By the beginning of 2009, Porsche announced at its headquarters in Stuttgart that it had held 50.76% of the ordinary shares of Volkswagen. At this point, I have to mention Porsche’s wishful thinking: if the acquisition is successful, Porsche can merge Volkswagen’s books, use Volkswagen’s funds or even sell Volkswagen’s assets by holding more than 50% of Volkswagen’s shares, and indirectly increase Porsche’s profits to pay off debts. Unfortunately, Porsche’s elaborate wishful thinking did not succeed. The acquisition was considered as a "hostile acquisition" by the German government and Volkswagen, and the Volkswagen Law still had a protective effect on Volkswagen. Therefore, Porsche’s acquisition of Volkswagen finally failed. However, this failure did not dispel Porsche’s idea of acquiring Volkswagen. The careerist is still eyeing Volkswagen.

  However, it didn’t take long for us to find out that this "beast" was actually a "paper tiger" that was weak in the outside. After April 2009, the impact of the world financial turmoil deepened. At this time, Porsche’s debt "high platform" built by the previous crazy acquisition was crumbling, with a total debt of 10 billion euros. Banks also tightened their money and ignored Porsche’s various "applications". At this time, Porsche not only failed in its wishful thinking, but also internally.

Home of the car

  While Porsche suffered the consequences of its aggressive acquisition, Volkswagen controlled its costs from 2007 to 2009, making a successful profit of more than 4 billion euros, and in 2009, it has quietly climbed to the second largest automobile manufacturer in the world.

Home of the car

  At this time, the Piech family thought it was time to implement their plan. In mid-2009, audi ag, led by the Piech family, decided to buy Porsche Automobile Company. Faced with the blow of "brothers", Porsche Company at this time seemed to be at a loss. On July 22 of that year, Volkswagen officially agreed to buy Porsche Automobile by investing 5 billion euros. However, it was not so easy to eat Porsche in one bite. In 2009, Volkswagen spent 3.9 billion euros to acquire 49.9% of Porsche’s shares in its holding company, and the remaining 50.1% of the shares had to be purchased from Porsche Europe joint-stock company before it could fully acquire Porsche cars.

Home of the car

  After being acquired by Volkswagen, Porsche’s business situation has been greatly reversed and it is booming. Volkswagen only provides financial support and does not interfere in the design, production and sales of its models, which makes Porsche cars like a duck to water, with frequent masterpieces, and quickly improves its market share. Volkswagen’s "Tai Ji Chuan" is really good.

Home of the car

  After nearly three years of close cooperation with Porsche, Volkswagen Group officially announced on July 4 this year that it will continue to invest 4.46 billion euros to acquire the remaining shares held by Porsche Europe AG. If the process goes smoothly, Volkswagen will own 100% shares of Porsche after this capital injection. However, this matter has not been implemented until now, and it seems that it will take time to completely solve the feud between Volkswagen and Porsche.

Summary:

  The 80-year feud between Volkswagen and Porsche came to an end with the overall victory of the Piech family. In the last 20 years, we have seen the hysteria of Porsche and the public’s fearlessness in times of crisis. Due to the various interventions of the Volkswagen Law, Porsche not only failed in its wishful thinking, but also ended up being "acquired". In addition, the intrigue and competition for interests among the wealthy families also left us a deep impression. The temptation of rights and the bursting of desires once made Porsche lose its direction, while the public was supercilious and tepid in the whole incident, which not only made them get away with it, but also "helped the brothers" at a critical moment to get Porsche out of trouble and get back on track. It must be said that this is what brothers should have.

If you choose a hundred-dollar refrigerator, your aunt can’t pick out any problems! Sanhuangjia laboratory

Searching for [mini refrigerator], [dormitory refrigerator] and [car refrigerator] on the e-commerce platform is the most common one. Its scientific name is [Semiconductor cooling and heating box] . The principle is very simple. When a special semiconductor is electrified, a temperature difference will occur between its two ends. One end in the refrigerator absorbs heat, and the other end outside the refrigerator emits heat, which will be blown away by a fan, resulting in a refrigeration effect.

The biggest advantage of this small refrigerator is that Cheap and small in size We chose seven 8-L mini-refrigerators on the e-commerce platform, the prices are basically around 100-200, and only delicious and Pepsi ones are more expensive. In addition, we also bought these two small refrigerators with 20L double refrigeration, as a control group, to see how different the small refrigerators are under different specifications.

There are many online complaints about small refrigerators, such as Refrigeration, crotch pulling, loud noise Some people are worried that it is just a sample and lacks practicality. More people are worried that the dormitory power supply or car power supply will not be able to move it. These are the questions to be answered in this program.

Refrigeration test

The first is the most critical refrigeration efficiency. We try our best to find a test environment similar to ordinary university dormitories, with slender apartment, one-sided ventilation, low floors and high floors.

Seven 8L mini-refrigerators to be tested are placed on the ground, and the back end is 20cm away from the corner, leaving enough space for the exhaust port. We use a temperature inspector, put the sensor in the middle of the box and record the temperature every five minutes.

The test starts at 20:00 every day and ends at 16:00 the next day, with a total length of 20 hours. During this period, the power metering socket will record the cumulative power consumption of the small refrigerators.

Test start An hour and a half After that, all refrigerators reached the maximum cooling capacity, and then there was no obvious change. Their refrigeration capacity is divided into four grades:

First gear Delicious and beautiful The temperature in the refrigerator is 17.5℃ lower than the room temperature; The temperature difference between the inside and outside of Oaks is 1℃ less than them, which belongs to the second gear; The third gear is Pepsi, with a refrigeration capacity of about 14℃; Xinfei, SAST, OGE The refrigeration effect is relatively average, which is more than 11℃ and does not exceed 12℃, ranking fourth.

But this is only the case of empty box test. If they are really used to freeze drinks, will there be any difference in refrigeration performance?

So next, we will fill most of the space of these refrigerators with drinks: this small refrigerator with 8L capacity is basically equipped with One bottle plus four cans of drinks is almost full. This load may be smaller than many friends expected.

In this round of test, we have arranged four temperature sensors in each refrigerator, two of which record the air temperature in the box, and the other two probes respectively extend into two cans close to the inner wall of the refrigerator to record the temperature of the liquid. The test still starts at 20:00 every day and ends at 16:00 the next day, with a total length of 20 hours.

The result is really different from the empty box test.

No matter the temperature in the box or the temperature of the liquid, there is no longer an empty box to test it for an hour and a half and then keep it stable. The cooling speed of the refrigerator has slowed down. And you can always see the downward trend of the temperature curve, although after 14 hours, this trend basically becomes very weak.

There have also been some changes in the ranking of refrigeration capacity of refrigerators.

Let’s look at the temperature in the box first. Oaks’ performance has improved, and it has become the same as delicious and Meiling. Xinfei also caught up with Pepsi, ranking second; By the end of the test, the remaining preclinical and OGE were only about 9℃ lower than the room temperature.

However, the result of liquid temperature is not the same as the air temperature in the box. Delicious, Meiling, Aux Still in the first gear, the performance is closer; The biggest difference is in the second gear, cooling drinks, catching up with Pepsi is Xianke, which is about 1℃ worse than Pepsi; The temperature in the box is ranked second. Xinfei Frozen drinks are the worst, worse than OGE.

Apart from Xinfei and Xianke, the temperature in the other five refrigerators and the temperature of drinks basically change synchronously, but the cooling rate of liquid is faster than that of air, and the final temperature is lower than that of air.

In fact, the temperature measured in all refrigerators is higher than that of empty boxes, and the temperature of drinks is lower than that of empty boxes, and the delicious coke is even lower than 0℃.

However, considering that this round of testing took three days to complete, the room temperature varies by about 1℃ every day. Perhaps due to the influence of room temperature, the cokes of Meiling and Oaks failed to freeze below 0℃? So we made another round of additional tests for the top three to see if they can still freeze out at the current room temperature of 25℃!

As a result, because the room temperature has increased, none of them can freeze the coke below 0℃ this time. However, the three refrigerators are also divided into high and low: Coca-Cola still has the cooling ability of 21.5℃, freezing the liquid temperature of Coke to 3℃; The cooling ability of Meiling and Oaks was obviously affected by the higher room temperature, and their coke liquid temperature stayed at about 6℃.

The above is the refrigeration situation of the 8L small refrigerator. What about the 20L one?

Just say these two models we bought, and the results are a bit confusing: Delicious 20L refrigeration is worse than 8L refrigeration. Pepsi’s 20L has gradually surpassed its own 8L. However, just when we were expecting it to be more than 20L delicious, the monitoring temperature suddenly bounced back. After the retest, it was confirmed that Pepsi was broken!

Power consumption test

Can the power supply in student dormitory support the work of small refrigerator? The e-commerce page is clearly written: The cooling power is about 40W. , the dormitory is available. Note that the 40W here is only when the refrigerator is empty. What will happen if the refrigerator is full?

At the same time of refrigeration test, we also used the power metering socket to test the real-time power of the small refrigerator filled with drinks and the accumulated power consumption after 20 hours of operation.

The test results show that when it is full, The refrigeration power of 8L small refrigerator is generally 50~55W. Continuous operation for 20 hours consumes about 1.1 kwh of electricity. There is no problem in using it in the dormitory. .

Among them, the small refrigerator with the best energy consumption control is Xianke, and the refrigeration power is basically less than half of other products; The second place to save electricity is the delicious 8L refrigerator with excellent refrigeration effect. However, the power consumption of the same 20L refrigerator is "outstanding"; Even more outrageous is Pepsi, whose 8L refrigerator is not efficient, but its 20L refrigerator is surprisingly energy-saving, which is lower than most 8L refrigerators, including Pepsi’s own.

Noise test

Compared with the power consumption of small refrigerators, people may be more concerned about noise.

In a room with a stable noise floor of 48~50 decibels, we tested the noise at the rear fan of each refrigerator, read the data for 20 seconds and recorded the average value.

Test results: the noise champions in the selection are 8L delicious and Oaks. Meiling, a little better. The quietest ones are Xinfei and Xianke. 8L Pepsi ranked third.

Purchase suggestion

After some tossing, we summed up three indicators to evaluate the performance and experience of small refrigerators: Refrigeration effect, power consumption and noise . And give purchase suggestions.

However, for a product like a small refrigerator, which one should you buy Depends on your usage scenario.

For the student party who wants to freeze drinks in the dormitory, Meiling is cost-effective, moderately priced, with strong refrigeration performance and good face value, but it is a little noisy. If you or your roommate is sensitive to noise, you have to settle for the second best, and choose Baccalaureate or Pepsi.

The new middle-class car-mounted refrigerator is recommended, with fashionable appearance and eternal refrigeration performance. If there is enough storage space, it can be upgraded to 20L, with limited performance loss, but it can hold many other foods besides drinks, so it is a good companion for camping.

As for OGE, which is the least recommended, it is really an all-round and balanced player. Not only is the refrigeration performance the worst, but the noise is also big. The key point is that the price is not much cheaper.

That’s all the content of this program. With a hard-core attitude, we will make a material evaluation. Here is the evaluation of Huang’s family, and a group of professional, interesting and serious friends are waiting for you.
