Shield machine is called "the king of construction machinery" and is an important symbol to measure the manufacturing level of a country. Today, seven out of every ten shield machines in the world come from China. What kind of industrial chain support is behind this? Look at the reporter’s first-line research.

In the assembly workshop of China Railway Equipment, the largest shield machine enterprise in China, the reporter saw that a number of shield machines exported overseas were being delivered centrally. If this shield machine is disassembled, there are more than 10 thousand parts. As can be seen from this industrial chain map, cutters and main bearings are mainly concentrated in Henan, motors are mainly located in Shanxi, and gears are mainly distributed in the Yangtze River Delta and Chongqing. And if we go back to 10 years ago, these key components still have to rely on imports.

Cutters, like teeth, determine the tunneling speed of a shield machine. The materials used as cutters should be high in hardness, corrosion resistance, good in flexibility and fatigue resistance. In order to overcome this special material, China Railway Equipment and Tsinghua University jointly tackle key problems, and conducted thousands of tests on more than a dozen additive elements, finally solving the problem of high strength and toughness of superhard materials.

As the "chain length" in the industrial chain, China Railway Equipment has driven the development of more than 1,200 enterprises through this collaborative innovation mechanism for many years. In this warehouse, the reporter saw that there were fifty or sixty rows of shelves with accessories such as motors and hydraulic pumps, just like a "parts supermarket for shield machines". Now more than 160 local enterprises provide supporting products and services for shield machines.

At the same time, engineers are constantly promoting the renewal and upgrading of shield machines. The types of shield machines have increased from two 10 years ago to 15 now. Originally, they can only move horizontally, but now they can go up and down slopes, turn corners and operate vertically. Now, the shield machine in China is still developing towards intellectualization and "unmanned tunneling".

Thanks to China’s complete industrial chain and continuous iterative technological innovation, today, China’s shield machine has occupied 70% of the global market, with thousands of upstream and downstream enterprises. Only China Railway Equipment and shield machines have received more than 1,600 orders, which have been exported to more than 30 countries and regions around the world, ranking first in the world in terms of production and sales for six consecutive years.

For military fans, it is definitely their dream car, and the arrival of it makes them dreams may come.

Although it is different from the military warrior’s purely functional orientation.,Warrior 917 focuses on luxury electric off-road, but the door handle with the shape of "desert eagle", the handle with the shape of airplane lever and the door closing also simulate the sound of pistol loading.Waiting is enough to make military fans ecstatic.. The key warrior 917 also inherited the cross-country gene of military vehicles.Hardware blessing such as 31 approach angle, 31 departure angle, 100% maximum climbing degree and 335mm maximum ground clearance.There is no need to say more about strength.

For this reason, I mainly drove it in Guangzhou this time. Look at this car’s width of nearly 2.1m, and it is inconvenient for a big guy with a curb weight of over 3.1 tons to pass through the city. As it turns out, the return rate of Warrior 917 on the road is really high, and the driving perspective of pickup truck with the same paragraph gives me a strong sense of security and satisfaction. besidesBenefit from10.6 rear wheel steeringThe turning radius of Warrior 917 is only 5.1mEven the old city can easily turn around, and there is no pressure on urban use.

However, if you want to enter the underground garage, you must remember to adjust the air suspension back to the standard height, just like the underground garage with a measured height limit of 2.2m m. When the air suspension is at the off-road height, it will scratch the height limit pole, and when passing through the underground garage, it will also scratch the sign. What happened specifically, you can open the video to see ~

When the vehicle is stationary, if abnormal behavior or illegal intrusion is detected around it, the vehicle will automatically take photos and videos and send an alarm to remind the owner. At the same time, the vehicle will automatically lock and start the anti-collision system to prevent further danger.

　　China news agency, Washington, February 22 (Reporter Chen Mengtong) The number of deaths in COVID-19 in the United States exceeded 500,000 on February 22. On the same day, US President Biden held a ceremony at the White House to mourn the death of COVID-19, and ordered the national flag to be lowered at half-mast until 26th.

　　According to the data of Johns Hopkins University in the United States, as of 16: 24 EDT on 22nd (5: 24 Beijing time on 23rd), the cumulative number of COVID-19 deaths in the United States exceeded 500,000, reaching 500,071, and the number of infected people exceeded 28.17 million.

　　At about 17 o’clock, the White House lowered its flag at half mast. The National Cathedral in Washington rang 500 bells to mourn the death of COVID-19.

　　"500,071 people died." At sunset, Biden made a speech on the COVID-19 epidemic at the White House. There was a pause when he read the number.

　　Biden said that in the past year, the lives lost by COVID-19 in the United States "exceeded the total number of people killed in the First and Second World Wars and the Vietnam War". "As a country, we can’t accept such a cruel fate. We have been fighting the epidemic for so long, but we must refuse to become numb to sadness, and we must refuse to regard every life as statistics, a vague thing or news. "

　　On the day before Biden was sworn in, there were more than 400,000 deaths in COVID-19. At that time, he arrived in Washington for his first public event, that is, he went to the reflection pool in front of the Lincoln Memorial to attend the national public sacrifice ceremony for the dead in COVID-19.

　　In his speech on the 22nd, Biden once again called on the American people to unite to fight the epidemic. "Stay alert, keep social distance, put on a mask, and get vaccinated when it’s your turn."

　　He then stressed that the United States must end the "political differences and false information" in the process of fighting the epidemic, which have torn families, communities and countries and caused too many lives. "It was not Democrats and Republicans who died of the virus, but our fellow Americans, our neighbors and friends."

　　After the speech, the Bidens and Vice President Harris came to the south side of the White House to observe a moment of silence for the 500,000 COVID-19 dead in front of the Washington Monument. Black veil is hung at the main entrance on the first floor of the White House. 500 burning white candles are arranged from the first floor along the stairs on both sides to the terrace on the second floor.

　　Despite the recent steady decline in the epidemic curve in the United States, the cumulative number of deaths continues to rise. Data show that the number of deaths in the United States exceeded 100,000 on May 27th, 2020, 200,000 on September 22nd, 300,000 on December 14th and 400,000 on January 19th, 2021. It took more than one month for the death cases to range from 300,000 to 400,000 and from 400,000 to 500,000.

　　The mainstream media in the United States used "shocking milestones" to describe this day. The Associated Press said that 500,000 was once "an unimaginable number" for the United States.

　　Fauci, an American infectious disease expert, said that the COVID-19 epidemic has never been experienced in the United States in 102 years since the influenza pandemic in 1918. "People will keep talking about it in the coming decades.".

　　According to the data of the US Centers for Disease Control and Prevention, as of the 22nd, over 44.13 million people in the United States have received at least one dose of COVID-19 vaccine, accounting for 13.3% of the total population. According to the data model of the University of Washington, by June 1, the number of deaths in the United States may exceed 589,000.

　　Biden also said that unity is the "only way" for the United States to overcome the epidemic. "Only in this way can we avoid more pain and loss. Only in this way can these heavy milestones no longer become national mourning days that need to be commemorated. "

　　What awaits innocent baby seals may be the fate of being killed.

　　

　　The hunter clubbed the seal on the head.

　　Canada’s commercial killing of seals has long been protested by many animal protection organizations around the world, but strong opposition can’t stop this cruel killing. The Canadian government even increased the quota for killing seals in 2008 to 275,000, an increase of 5,000 compared with last year, which triggered widespread criticism and protests around the world.

　　The killing scene is extremely cruel.

　　Every year from March to April, Canada conducts large-scale commercial hunting and killing of seals. These seals are either shot with guns or hit on the head with sticks, and the scene is extremely bloody. At the beginning of hunting, the hunters in the dinghy shot at once after seeing the seal on the ice. After killing the seal, the hunters peeled off the fur from the seal and threw it into the dinghy. Seal fur will be used to make leather clothes, and the bodies will be discarded.

　　After the seals were shot, the hunters began to check their sex. If the female seal is killed, cut open and peel it on the spot, leaving the stripped flesh and blood in place; When they meet male seals, they drag their bodies to fishing boats, and then send them to processing plants for subdivision later. There are also some hunters who are extremely cruel. They snatch the baby seals directly from the mother’s arms, knock these young and helpless lives to death with sticks, and immediately peel off their fur. When the baby seals, who had just been born for two or three weeks and were starving, were lying in the sun on the smooth ice, the hunters’ sinful bullets had been continuously fired at their young bodies. Poor little guys have been skinned and boned before they can eat solid food, swim or even catch a cod to satisfy their hunger.

　　Seals, a beautiful animal, are killed because they are all treasures, and their fur is used to make high-grade garments. In addition, their adipose tissue contains an unsaturated fatty acid called "omega 3", which is more than that of natural fish. People extract this substance and make it into precious nutritional supplements for sale in the market, and the demand is very huge.

　　Animal protection organizations expressed strong protest.

　　The cruel killing of seals, like whaling, has attracted protests from many animal protection organizations from the beginning. Many animal protectors think that the killing of seals is so cruel that there is no one to talk about. Sherry, a member of the International Animal Welfare Foundation? Sheryl Fink said that she was surprised that the Canadian government continued to increase the quota for hunting seals, and said that this behavior should not continue. She said: "This resolution to increase the quota for killing seals is unfair."

　　As early as 2005, some environmentalists began to urge some American restaurants to boycott Canadian seafood unless the Canadian government stopped the commercial killing of seals. They said that the EU will soon introduce a ban on all seafood imports from Canada. Some animal protectionists say that the current Conservative government in Canada actually allows the killing of seals in order to win the support of the eastern region in the next federal election.

　　However, despite the wave of protests, the Canadian government is indifferent. Phil Jenkins, a spokesman for the Fisheries and Oceans Department of Canada, recently denied that the population of Harp Seals in Greenland has decreased. He said, "At present, the number of Harp Seals in Greenland is good and sufficient, about 5.5 million. We hope to see these animals continue to grow healthily, so we have been keeping the number of seals killed within a reasonable range for many years. In addition, he also said: "We have a conservative method to keep the number of seals. We think that killing 275,000 seals is not enough to pose a threat to the number of seals." It is reported that the Canadian government has planned to set the date of killing seals in late March. (Dong Nan)

　　The data map shows Russian President Vladimir Putin. China News Agency issued Liao Wenjing photo

　　New Express News The British "Guardian" quoted internal sources of Putin’s government as saying that the Russian Kremlin was fighting among billions of dollars of state-owned assets, and it was revealed for the first time that Putin had secretly accumulated more than 40 billion dollars (about 300 billion yuan) of assets during his eight years in power. It is said that he owns large shares in three Russian oil and gas companies, and whether Putin can keep his assets after leaving office has become the core issue.

　　Putin is the richest man in Europe.

　　In an interview with the British newspaper The Guardian on the 21st of last month, Russian political scholar Bierfus said that Putin holds the shares of three Russian energy giants through overseas opaque trust funds, including 37% of Surgutneftegaz, Russia’s third largest oil development company, with a value of 20 billion US dollars (about 150 billion yuan) and 4.5% of Gazprom)4.5% Putin’s personal net worth exceeds $40 billion, making him the richest man in Europe.

　　Cover up with an overseas company

　　According to the report, Putin owns as much as 75% of the Swiss-based Gunvor oil trading company founded by his friend timchenko. Gunvor’s operation is very mysterious. It has neither an official website nor an office in Moscow, but this year it announced an astronomical profit of 8 billion US dollars (about 60 billion yuan) and a turnover of 43 billion US dollars (about 330 billion yuan).

　　Berfsky said: "Putin has at least $40 billion, how much is unknown at most, and maybe there are other businesses I don’t know … Putin’s name will certainly not be made public on the shareholders’ register, and these offshore companies will not make public equity transactions."

　　Putin’s wealth has always been a taboo for Russians. This time, it was revealed that the current internal struggle in the Kremlin is an important incentive. It is reported that Medvedev and other "liberals" nominated by Putin as the next Russian presidential candidate are competing with a group of national security agencies headed by Xie Qin, deputy chief of staff of Kegong, for the control of billions of dollars of state-owned enterprises’ assets.

　　An out-and-out "businessman"

　　Bilfsky, who has written about Putin, believes that western countries have been deceived by Putin’s image as a "new Soviet" politician. He described Putin as a "typical" businessman, believing that money makes the mare go, and his ideas were deeply influenced when he worked in the mayor’s office of St. Petersburg, which was in the early 1990s when Russian crimes were rampant.

　　Bieshi said that money is the only way for Putin to achieve his goal. Panfilov, the leader of Transparency International in Russia, pointed out that the "random" corruption of the Russian government in 1990s had evolved into "systematic and institutionalized corruption" in Putin’s era.

　　The oil company responded

　　Putin is not a "beneficiary"

　　Gunvor Oil Trading Company issued a statement on 21st, denying the rumor that Russian President Vladimir Putin was the "beneficiary" of the company, which was the first response of the company on the relationship with Putin.

　　Tarnqvist, CEO of Gunnvor, sent a letter to The Guardian, in which he said that it was "extremely wrong" to say that the company benefited from its close relationship with the Kremlin. Putin is not the beneficiary of the company’s business activities, and neither he (Putin) nor his friends are shareholders of the company.

　　Tarnqvist also said that Gunnvor’s profits were exaggerated. He acknowledged the revenue figures reported by the media about the company, but refused to disclose its profits in 2007.
