In the field of chemical investment, soda ash is an important basic chemical raw material, and its price fluctuation has a significant impact on the whole industry. Analyzing the reasons for the decline in the value of soda ash will not only help investors understand the market dynamics, but also provide valuable enlightenment for chemical investment.

First of all, the relationship between supply and demand is one of the core factors affecting the price of soda ash. When the supply of soda ash in the market increases and the demand is relatively stable or decreasing, the price often falls. For example, in recent years, with the improvement of domestic soda production technology and the expansion of production capacity, the supply has increased significantly. At the same time, influenced by the global economic slowdown and environmental protection policies, the demand growth of soda ash slowed down, which led to the imbalance between supply and demand and the price fell.

Secondly, the change of raw material cost is also an important factor affecting the price of soda ash. The main raw materials of soda ash include limestone, salt and ammonia. If the prices of these raw materials fall, the production cost of soda ash will be reduced, which may lead to a decline in the price of soda ash. For example, in recent years, with the development of limestone and salt resources in China, the prices of these raw materials have declined, which has further affected the market price of soda ash.

In addition, changes in the macroeconomic environment will also have an impact on the price of soda ash. The fluctuation of economic cycle, the change of monetary policy and the change of international trade situation may affect the demand and price of soda ash. For example, in the global economic downturn, industrial production activities have decreased, the demand for soda ash has declined, and the price has also fallen.

In order to show the influence of these factors on soda ash price more intuitively, the following table lists the changes of soda ash price and main influencing factors in recent years:

As can be seen from the table, with the increase of supply, the decline of raw material prices and the deterioration of macroeconomic environment, the price of soda ash shows a downward trend year by year.

For chemical investors, it is of great significance to analyze the reasons for the decline in the value of soda ash. First of all, investors should pay close attention to the changes in the relationship between supply and demand and adjust their investment strategies in time. Secondly, the fluctuation of raw material cost should also be the focus of investors’ attention. By analyzing the dynamics of raw material market, the price trend of soda ash can be predicted more accurately. Finally, the changes in the macroeconomic environment cannot be ignored. Investors should have a global perspective and pay attention to the international economic situation in order to better grasp market opportunities.

In short, through the in-depth analysis of the reasons for the decline in the value of soda ash, chemical investors can better understand the market dynamics and formulate more scientific investment strategies, so as to obtain greater benefits in the complex and ever-changing market environment.

In the domestic market, Geely Binyue mainly competes with changan CS35 PLUS, Chery and other small brands, among which the sales volume of the 2024 model was 7,911 vehicles in January. As for whether the new car can achieve a further breakthrough in sales, let us wait and see.

Previously, the extended-range four-wheel drive version of Star Era ET was mentioned many times, but the real car has never been seen. The real car also officially appeared in the catalogue two months ago. However, the word four-wheel drive was not explicitly mentioned in the catalogue, but the judgment was made based on the substantial increase in the weight of the whole car. Later, the media real car experience video appeared, which basically confirmed that the author’s initial judgment was right, and there was an extended-range four-wheel drive version. At present, the only pity is that the real car has not been photographed. Recently, this shortcoming has finally been made up, although it is not.(Pictures and texts shall not be used or reproduced without permission)

There is no doubt about the appearance. The test car is basically the same as that in the catalog declaration drawing, and the letter mark on the front of the car is also EXEED letter string. However, if you look at the license plate box in self-study, this slender strip is obviously not a domestic license plate. That is to say, this time you encounter an export version of the test car. The adaptation test should be aimed at some overseas environments, and the official export will be replaced with EXLANTIX letter string. In addition, pay attention to the active grille appearing at the lower end, which is not needed on the pure electric version.

There is naturally no change in the side, but if you look at the hub carefully, the shape of the hub has appeared in the catalogue declaration of the previous two months, which is the shape in the catalogue of the extended-range four-wheel drive version, that is, the hub has only seen a few more eyes, otherwise it is impossible to tell whether it is an extended-range or a pure electric version by its appearance.

The tail is more direct, and all information signs are simply erased. It is hoped that the model will be judged by the tail logo information. Of course, the tail has not changed, and erasing all logo information is obviously aimed at other uses, such as overseas markets. After all, the export version has been renamed as "Atlantis".

After a look at the interior, it remains the same. It seems that there is a tacit understanding between the domestic version and the export version, except for the differences in configuration. At present, there is a HUD head-up display on the test car. By the way, depending on the regional differences in the global market, there may be HUD in some places, while others may not. Of course, this has nothing to do with the domestic market, so just know.

Looking forward to looking for the relevant information of the four-wheel drive version, the word four-wheel drive appeared on the hood. After a closer look, it seems that it is a mistake. I feel that four cars start from XX, and the last two words are really casual. I didn’t understand it at all. It seems difficult to expect to make a judgment through the hood.

Turning our eyes to the chassis, we can first make sure that the extended-range version is not running, and the rear muffler and exhaust pipe lines are clearly distinguishable. In addition, we should pay more attention to the details because the rear suspension control arm is also equipped with anti-collision sleeves. However, it is still impossible to judge whether it is a two-wheel drive version or a four-wheel drive version. The rear drive motor represents the rear drive version, which is not necessarily related to the four-wheel drive. In addition, this model does not have the transmission shaft of the traditional mechanical four-wheel drive system, so it is difficult to judge the details.

Finally, in an inconspicuous position, I found the clues of the four-wheel drive version, and I can see the word E0Y REEV four-wheel drive. Although it is not very clear, I can still see it. From this point of view, the judgment through the wheel hub is correct. This is an extended-range four-wheel drive version of the real car. Since it is aimed at overseas markets, it has naturally not run in China. After all, it has appeared in the catalogue, and it is not clear when it will be launched. Starway’s marketing team has never been coherent. Basically, it’s just a matter of having a date and not having a date, and then it’s quiet, and sometimes it suddenly reminds me that it’s casual.

Originally, I wanted to hammer the four-wheel drive version through the front drive motor, but it was shattered by the front guard. I couldn’t see any details at all, only one corner of the aluminum alloy hanging from the front lower control arm was exposed, and I was not forced. After all, it was impossible to disassemble the car on the spot, but it was a four-wheel drive version.

Naturally, the next step is to wait patiently. Anyway, the domestic listing didn’t happen, but I don’t know exactly when. Anyway, I just know that this car exists. Once it is realized, many extended-range models are actually waiting. I’m afraid that’s the value of Starway/Star Age now. The new guy is holding on to it first, and the sales volume is just so-so, but the advantage is that after the technical trial, other models can follow up quickly, not to mention a few models developed on E0X platform in the future. Especially for key models such as E05/06, there are plans for extended range versions, and the four-wheel drive version will also appear in the configuration list in the future, so the significance is still very significant, but it is only for the four-wheel drive itself, and the car is another topic.

In the electric vehicle market, endurance has always been one of the most concerned topics for consumers. Recently, the endurance test has caused a heated discussion, and many people are full of curiosity about the performance of this car. So, how far can Extreme Leap 07 run? Today, I will take you to know more about it.

First of all, let’s take a look at the basic information of Extreme Yue 07. This car is not only fashionable in appearance and luxurious in interior, but more importantly, it is equipped with a high-efficiency power system. Is the endurance that car owners and potential buyers care most about reliable? This endurance test will give us the answer.

In the actual test, we chose urban, high-speed and mixed road conditions to simulate the daily driving situation as much as possible. In order to ensure the fairness of the test, we conducted several tests under different weather conditions and collected various data.

At the beginning of the test, the power of the polar battery 07 showed 100%. When driving on urban roads, the energy consumption of vehicles is excellent. Even if the traffic signal changes frequently, the power consumption of the car is still well controlled. According to the test results, the cruising range of Extreme Yue 07 is still within the expected range after the congested road section in the peak period.

Then, we drove the vehicle to the high speed and started the long-distance endurance test. In high-speed driving, the battery consumption increases correspondingly because of the faster speed. But to our surprise, at the speed of 120 km/h, the endurance performance of Extreme Yue 07 is still relatively stable. Without stopping, after running for nearly 300 kilometers, the power is still reserved. This is a surprise for many car owners who need to travel long distances.

Next, we returned to the city with Extreme Yue 07 for the final test. In the actual driving in the urban rush hour, the flexibility and endurance of the vehicle make us feel the superiority of the 07. Through the rational use of regenerative braking technology, the vehicle can effectively recover some energy and further extend the cruising range.

It is worth mentioning that the intelligent driving assistance system equipped with the Extreme Yue 07 also helps us to control the vehicle more easily in the complex traffic environment. This not only improves the driving experience, but also reduces the waste of electricity to some extent.

After a whole day of testing, the final result is exciting. The actual endurance performance of Extreme Yue 07 in different scenes far exceeded our expectations, with a total cruising range of nearly 600 kilometers! This performance is enough to meet the daily needs of most families, whether it is commuting in the city or go on road trip on weekends.

Of course, only relying on endurance, Extreme Yue 07 does not stop there. It has also performed quite well in driving comfort, interior design and technology configuration. Through this endurance test, we not only verified the battery performance of the Extreme Yue 07, but also saw the overall driving experience it provided to consumers.

To sum up, the endurance of Extreme Yue 07 is really impressive, and it can bring you confidence whether you are roaming in the city or traveling long distances. If you are considering buying a new energy vehicle, you may wish to include the Extreme Yue 07 in your shopping list.

I hope this tweet can help you, and I hope everyone can actively participate in the discussion and share your opinions. What do you think about the endurance of Extreme Yue 07? Welcome to leave a message in the comment area and chat together!

　　Recently, the United States and Europe have been arguing about whether and how to provide MIG -29 fighters to Ukraine. First, at the request of the United States, Poland expressed its willingness to send its MiG -29 to the Ramstein Air Force Base in Germany, which was dominated by the United States. The United States quickly stopped it, saying that Poland’s idea was too risky because the United States and NATO tried to avoid a direct conflict with Russia.

　　▲ The first MIG -29 prototype "Blue -01" parked in the Central Air Force Museum of Monino Airport.

　　Obviously, the United States wants to be a "non-stick pot."When MiG -29 takes off from its own base and goes to Ukraine, there is bound to be the risk of retaliation by Russia, so it simply doesn’t take this "dirty job". It is not difficult to see that in the Ukrainian crisis, the United States has been pushing European countries ahead, letting them block bullets and be cannon fodder.

　　Although the United States led European countries to launch verbal attacks and unprecedented sanctions against Russia, it did not consider the safety and interests of European countries.In this "sanction carnival" which was kidnapped by western politics correctly, the interests of Europe were completely betrayed, but many European friends were still ignorant and impassioned.As people who eat melons, I am anxious for them.

　　In this crisis, Europe’s contribution has just begun.

　　First, the European security architecture has collapsed.The geopolitical map of Europe is being rewritten, and the security framework that Europe has been striving for for for 30 years after the Cold War no longer exists. Instead of bringing more security to Europe, NATO has constantly provoked and squeezed Russia into a situation of Jedi counterattack.

　　Since the end of the Cold War, NATO has violated the promise of "never moving an inch eastward" and pushed to the Russian border through five rounds of eastward expansion. Putin said that if ballistic missiles are deployed in Ukraine, they can reach Moscow in seven or eight minutes, and hypersonic missiles only need four or five minutes. This is equivalent to putting the muzzle on someone else’s doorstep. Can Russia bear it? Can you live if you endure it? The answer is no.However, the opening is easy to end. After the United States angered Russia, it put up a "war-free card" and left the rest of the mess to Europe.

　　Second, the economic losses in Europe will gradually emerge.The United States has imposed crazy sanctions on Russia from Europe, from space to aviation, from chips to oil and gas, from financial chain to industrial chain, trying to completely cut off the economic ties between Europe and Russia. In reality, the EU is the largest foreign investor in Russia. In 2019, European direct investment in the Russian market has exceeded 311 billion US dollars. In 2020, the trade volume between Europe and Russia exceeded US$ 174.3 billion. These close and active economic, trade and financial ties have been cut off. How many European enterprises will suffer losses and how many European workers will be forced to lose their jobs?

　　Russia and Europe closed their airspace to each other because of sanctions, and flights from European countries to East Asia had to go around Russia, and the cost increased sharply. The United States has a superior geographical position, but its airlines are little affected. In addition, there are 2 million Ukrainian refugees flooding into Europe, which will also bring a heavy economic burden to European countries and even cause a lot of social problems.We can see that the European people welcome the refugees very touching, but the enthusiasm is temporary after all, and a series of problems caused by refugees have been learned from the past.

　　▲ In October 2015, a large number of refugees from Middle Eastern countries gathered at the border between Slovenia and Austria.

　　Third, Europe’s energy supply is precarious.Affected by the situation in Ukraine, the data of London Intercontinental Exchange (ICE) showed that the European natural gas futures price rose to nearly $3,900/thousand cubic meters on March 7, which was more than ten times the price last spring, while 55% of Germany’s natural gas and 40% of its oil and coal were imported from Russia. Therefore, German Chancellor Angela Scholz still insists on exempting European sanctions on Russian energy under the pressure of the United States and Britain.

　　However, on March 8, US President Biden announced a ban on the import of Russian oil and natural gas. As soon as the voice fell, US Deputy Secretary of State Newland said at a congressional hearing that the "Nord Stream 2" project was dead. This Russian-European joint investment of nearly 10 billion euros in natural gas pipeline was thus lightly sentenced to death by the United States.

　　▲ On March 8, 2022, Biden announced that he would impose an energy embargo on Russia. On the same day, the EU also announced that it would seek to significantly reduce oil and gas imports from Russia. This sanction will push Europe’s energy supply into trouble. (Comic | Liu Rui)

　　European media believe that the Ukrainian crisis will seriously impact European energy supply, and many people will face the choice of starving or freezing this winter and next spring.People of insight in German political circles have publicly stated that "some people say that we are ready to pay a high economic price to get rid of our energy dependence on Russia, but it is the people who pay the price".

　　Sanctions against Russia, the whip also hit Europe.

　　Europe is a mess, and everything goes well in America.The conflict between Russia and Ukraine has made the United States harvest a lot, and many things that we wanted to do before but failed to do have been accomplished: Russia will be difficult to turn over morally or in terms of national strength in the short term, Europe will be more "United", NATO will be more "centripetal", Nord Stream 2 will be terminated, the defense budgets of Germany and many European countries will exceed 2% of GDP, and American oil, natural gas and arms can be sold in the European market.

　　Looking back at the routine of the United States in this crisis, it is roughly fanning the flames before the war breaks out, fearing that the world will not be chaotic, and sending information and weapons after the war breaks out, but insisting that it will never send troops.The wishful thinking of the United States is to let Ukraine bleed, let Europe pay the bill, and let Russia collapse. This is a typical routine of hegemonic logic and the latest application of offshore balance.

　　Does the United States really care about the interests and feelings of Europe? Friends in Europe can recall two things from last year.Last March, at the instigation of the United States, the European Union imposed unilateral sanctions on China on the trumped-up "genocide" in Xinjiang, which was resolutely countered by China, and China-EU Comprehensive Agreement on Investment, which was reached through long and arduous negotiations, was shelved by the European Parliament. Is this in the interest of Europe? No. This is only in the interest of the United States.

　　In September last year, the United States suddenly announced that it would form a trilateral security partnership (AUKUS) with Britain and Australia and would provide nuclear submarines to Australia, openly tearing up the submarine procurement agreement reached between Australia and France and "stabbing" NATO brothers behind their backs. Is this in France’s interest? No. This is only in the interest of the United States.

　　▲ In September 2021, Australia abandoned the submarine project with France since 2016, announced the establishment of a new partnership with the United States, and gave France a hard "backstab".

　　In recent years, French President Macron and other European leaders have loudly called for strengthening the EU’s "strategic autonomy". This is far-sighted, but the key is to realize ideological autonomy independent of the United States.Falling into the American discourse system has made it difficult for many Europeans to see the reality clearly, let alone form an independent strategy. At present, European public opinion is furious, and rational thinking has long been kidnapped by emotion and morality.

　　▲ On February 26th, 2022, the outer wall of the Russian Consulate General in Strasbourg was painted with Nazi symbols.

　　Over the years, the American propaganda machine has continued to "demonize" Russia.In the eyes of the West, Russia is a loser who lost the Cold War and a "second-class citizen" who once wanted to integrate into the West and was rejected. When Biden delivered his State of the Union address, he declared that it was a big tone and a deep prejudice to make Putin an "untouchable" on the world stage.

　　As a result, Russia has been portrayed as a demon hiding in the dark to spy on the West and wait for revenge.All its actions to defend legitimate security interests are regarded as the counterattack of darkness against light and the attack of authoritarian regime on the free world, which naturally deserves worldwide crusade and sanctions.On the other hand, the United States and NATO themselves can hold high the banner of democracy, human rights and freedom and bombard Iraq and turn Syria into rubble.

　　▲ In March 2019, the United States launched an air strike on the town of Bagzi in Syria, killing more than 60 women and children.

　　What about independent thinking and independent judgment of European media? In the information society, if the media have political prejudice and only follow the script obtained from a certain aspect, it will form a wrong public opinion. In the west where votes are paramount, wrong public opinion will form strong public pressure and then kidnap public decision-making. People’s anger is one-sided, rational voices are buried, and government decisions are held hostage. In the long run, there will be no problems.

　　▲ On March 7, 2022, Claire Daley, a member of the European Parliament, questioned at the plenary session of the European Parliament that thousands of Afghans left their homes and sought refuge, but no one mentioned it. Is it just because the invaders are the United States?

　　However, the narrative of American freedom and democracy has come to an end.Under this crisis, the United States and the West have indiscriminately banned Russia in political, economic, cultural, sports, literature and art, education and other fields, and the sanctions against Russia have reached a "new height": permanent neutrality is no longer neutral; The so-called art and sports have no borders, and politics is everywhere; Private property is sacred and inviolable, and can be deprived at will. What about the agreed spirit of contract? The hypocritical rhetoric that the United States has built for so many years has been completely "faced" by itself.

　　In fact, the United States has never given up its own interests because of ideology, because it is only the shell of interests; Europe, on the other hand, is often "not free or give me death", and constantly performs the drama of "losing money and making money" in geopolitics.It should be noted that when people play cards, they will inevitably become cannon fodder.Ukraine is one card, and Europe is another.America is the real super player, smash one, and there is another. As long as the east and west ends of Eurasia never stop, the hegemony will sit firmly. We would like to invite European friends to think together. Is the Russian-Ukrainian conflict a "self-fulfilling prophecy" or an elaborate strategy?

　　Man learns truth at the expense of suffering. What can we learn from the Ukrainian crisis?

　　The serious lack of mutual trust among major powers has led to the return of geopolitical conflicts.There is no mutual respect and basic trust between big countries, and in the end it is a war against each other.China’s philosophy says "extremes meet", and the result of one-sided pursuit of maximizing security interests is the collapse of the security system, which makes everyone unsafe.

　　Since the end of last year, Russia has also tried to solve its core security concerns through negotiations with the United States, and the response is only arrogance and perfunctory, leaving Russia with only "dealing with the jungle law with the jungle law." Two days ago, Putin quoted Catherine II as saying, "As long as I have enough life, I will defend my motherland with words, pens and swords."

　　When the security interests and national dignity of a big country are trampled on wantonly, it is the moment when war comes.Some people exclaim that traditional geopolitics has returned, and great power confrontation has returned. Who is the initiator? Can only blame the cold war mentality, hegemonic countries.

　　Pushing Russia into a desperate situation is a historic failure of the West and a tragedy of Europe.The United States can still watch the fire from the other side of the bank, and even provide MIG -29 fighters to Ukraine with fake hands in Poland. And where can Europe hide? There is only so much room in Europe. After the war, the distance between Berlin and Moscow is still 1600 kilometers. European countries will still live on the same continent as Russia and re-explore the possibility of building a security architecture. And why can’t all this start before the conflict breaks out?

　　▲ In the eyes of the United States, Europe is just a "marionette" manipulated to safeguard its hegemony and interests. (Comic | Liu Rui)

　　Maintaining hegemonic status is the core of American foreign policy, and we can do whatever it takes to achieve this goal.Europe is an important pole in the multi-polarization of the world and an important force to promote the democratization of international relations. It should seek and adhere to strategic autonomy in all fields and not act as cannon fodder for the United States to safeguard its hegemonic "cause".

　　Life newspaper May 19 th The wild Siberian tiger was first discovered in China on May 20 last year, and it has been occupied by Raohe County and surrounding forest farms for a whole year. Experts say that in its mind, this area is its territory. It used to be just a transit, and there is no sign of leaving this year. The natural environment in our province is improving, which provides a broad living space for the Northeast Tiger. Moreover, this Northeast Tiger is a "foodie". According to the statistics so far, it has eaten five roe deer, two wild boars and a cow.

　　According to Sun Chengfu, director of the Wildlife Protection Office of Raohe Forestry Bureau, after follow-up research, DNA identification and behavioral research, it has been confirmed that this tiger has settled in our province, but it is not the only one that is hard to say, because there are reports of activities of the Northeast Tiger in other forest areas.

　　　What did you do this year?

　　　1. A large number of claw marks were found on the trunk of contiguous forest land.

　　"This tiger has formed a fixed territorial scope, showing a specific demarcation behavior of wild animals." Sun Chengfu said. The territory of the wild Siberian tiger is about 1000 square kilometers for males. The contiguous forest land here is suitable for the Siberian tiger to settle down, and its forest area is close to 1000 square kilometers.

　　"When the Northeast Tiger takes a fancy to a place, it will leave paw marks on the tree and mark the boundary with urine. If there are these marks, other tigers will not invade without authorization." Sun Chengfu said that they found a lot of claw marks on the thick trunk of the territory boundary, which is called "hanging claws", and urine was collected in winter.

　　　It has been found to have eaten five roe deer, two wild boars and a cow.

　　On December 12 last year, Sun Chengfu and his colleagues took more than 100 photos of the Northeast Tiger eating cattle with a far-infrared camera, which is quite precious. On the same day, they received a report from the villagers that his old cow might have been attacked by the Northeast Tiger. Sun Chengfu rushed to the scene and found that the cow was eaten by a third of the tiger. More than 200 kilograms of adult cattle, the Siberian tiger killed it effortlessly, and dragged the body for hundreds of meters, hiding it in a deep ditch on the edge of the corn field. Sun Chengfu judged that the tiger would come back if the beef was not finished, so he arranged the shooting equipment nearby. Sure enough, the next day, the Siberian tiger returned to the scene and moved the beef to eat again.

　　Sun Chengfu said: "From the photos, this Siberian tiger is strong and well-nourished, indicating that there is enough food. According to statistics so far, it has eaten five roe deer, two wild boars and one cow. "

　　I went back to Russia to "find someone" and came back two months later.

　　This tiger went back to Russia once, and Sun Chengfu speculated that it was going back to "find an object". In the middle of December last year, during the patrol, Sun Chengfu found that the tiger trail extended to the Sino-Russian border. He tracked it for more than 20 kilometers and found that the tiger trail crossed the center line of the main channel of the Wusuli River and disappeared on the Russian side.

　　Two months later, the Northeast Tiger returned to the territory of Raohe County. Sun Chengfu said: "After mating, the Northeast tiger went back to its territory, and this tiger returned to China, which once again proved that it had settled in our province."

　　　4. I once strolled to the human activity area, 10 meters away from the fishing room.

　　"Leave as soon as possible in case of the remains left by tigers. Maybe the Northeast Tiger is not far away." According to reports, this Siberian tiger is not afraid of people, and it has been recorded in the vicinity of human activities. The last time it was 10 meters away from the fishing house by the river. On the 16th, Raohe Forestry Bureau issued an announcement to remind the general public, "Don’t enter the mountain at will for personal safety". According to reports, local residents generally walk together in the mountains, carrying firecrackers with them, driving tigers away with firecrackers, and trying to stay away from the Northeast Tiger activity area.

　　First discovery: May 20th last year.

　　A five-or six-year-old male adult tiger left a trail of footprints in farmland.

　　Raohe County is located in the northeastern border of our province, with a border line of 128 kilometers and a forest coverage rate of 51%. This area is one of the important corridors and activity areas for Siberian tigers to enter China from Russia. In recent years, many Siberian tigers have been active in the forestry application area here.

　　"This Siberian tiger was first discovered on May 20 last year. From this day, it has been here for one year." Sun Chengfu said.

　　Last year, a series of footprints left by the Northeast Tiger in the farmland exposed its whereabouts. "At that time, experts from the Cat Research Center of Northeast Forestry University happened to be investigating in Raohe River. After discovering the paw prints, the experts unanimously concluded that it was the footprints of the Northeast Tiger. Through the size and depth, the experts thought it was a male adult tiger, and the tiger was five or six years old." Sun Chengfu said.

　　Goodbye tiger trail: March 1 this year

　　The feces of Amur tiger collected again are the same as before.

　　The local animal protection staff conducted a follow-up study. In addition to taking photos and infrared cameras, they also collected the feces of Siberian tigers many times. On March 1, 2018, the tiger trail was found again in Shiye District of Tonghe Forest Farm. After 7 days of tracking, the wildlife department of Forestry Bureau collected the feces of the Northeast Tiger again and sent it to Northeast Forestry University for DNA identification. Compared with the previous feces, it was judged to be the same tiger.

　　Video tiger: April 23 this year

　　20 pairs of far-infrared devices captured 3 seconds of video.

　　Sun Chengfu said that 20 pairs of far-infrared camera equipment have been put into the territory of the Northeast Tiger, each pair of equipment includes a camera and a video camera, 10 warning signs have been set up in key activity areas, and 14 patrolmen are responsible for the protection and investigation of the Northeast Tiger. At 3 o’clock in the morning of April 23 this year, infrared camera equipment captured a 3-second video of the Northeast Tiger. The video shows that this Siberian tiger walked deep into the jungle through the forest road. This is the only video of this Siberian tiger.

　　Recent trail: May 10th this year.

　　I enjoyed another wild boar more than a week ago.

　　Sun Chengfu said that on May 10 this year, it was the last time they photographed the trail of this wild Siberian tiger. A wild boar killed by it had been hollowed out. "The pork hasn’t had time to eat, which means it may be not far away, so I only took a photo at that time and immediately evacuated."

Today, let’s take a look AT the AT gearbox and the dual clutch gearbox, which one should we choose? Please see next.

AT gearbox:Variable speed is realized by hydraulic torque converter and planetary gear set. Hydraulic torque converter uses liquid to transmit power, which can cushion the power impact of the engine; Planetary gear sets realize different transmission ratios according to different combinations.

dualclutchtransmissionThe odd and even gears are controlled by two clutches, which is equivalent to integrating two sets of manual gearboxes. When shifting gears, prepare the next gear in advance to realize fast shifting.

Shift speed: the shift speed of dual clutch gearbox is extremely fast, usually only about 0.2 seconds, while AT gearbox is relatively slow.

Transmission efficiency: the transmission efficiency of dual-clutch gearbox is high, and the power loss is small, which can generally reach about 85%-90%; The transmission efficiency of AT gearbox is relatively low, about 70%-85%.

Driving experience: the dual-clutch gearbox is more direct and neat when shifting gears, which can bring better driving pleasure, but it may have a sense of frustration when driving at low speed; The shift of AT gearbox is relatively smooth and comfortable, but the dynamic response may not be as direct as that of dual clutch gearbox.

Structural complexity: AT gearbox has a complex structure, including hydraulic torque converter, planetary gear set and other components; The structure of dual clutch gearbox is relatively simple, similar to manual gearbox.

Cost: Generally speaking, the manufacturing cost of AT gearbox is high, especially the high-end AT gearbox; The cost of dual clutch gearbox is relatively low, especially dry dual clutch.

Good ride comfort: the existence of hydraulic torque converter makes the shift process softer, the shift feeling is obvious and the driving comfort is high.

Large torque bearing: able to bear large engine torque output, suitable for all types of vehicles, including high performance and large vehicles.

Mature technology: it has a long history of development, relatively mature and stable technology, high reliability and low failure rate.

Simple operation: the driver only needs to control the throttle and brake, and there is no need to manually shift gears, so the operation is simple and easy.

Disadvantages:

Low transmission efficiency: power will be lost in the transmission process, resulting in relatively poor fuel economy.

Complicated structure: The complicated structure makes AT gearbox bulky, heavy and costly to manufacture.

Slow shift speed: compared with the dual clutch gearbox, the shift speed is not fast enough, which affects the dynamic response and acceleration performance of the vehicle to some extent.

High fuel consumption: Due to the low transmission efficiency and its own structural characteristics, the fuel consumption of AT gearbox vehicles is relatively high.

Fast shift speed: it can complete the shift operation in a very short time, and the power interruption time is short, which can provide better acceleration performance and driving experience.

High transmission efficiency: direct power transmission reduces energy loss and improves fuel economy, especially at high speed.

Simple structure: Compared with AT gearbox, it is relatively simple in structure, small in size and light in weight, and easy to install and arrange on vehicles.

Low cost: the manufacturing cost is relatively low, which helps to reduce the price of the whole vehicle.

Disadvantages:

Low-speed setback: Under low-speed driving, frequent start-stop or congested road conditions, there may be setbacks, which will affect driving comfort.

Reliability problem: There were some reliability problems in the early dual-clutch gearbox, such as clutch overheating and wear, but with the continuous improvement of technology, the reliability has been greatly improved.

High heat dissipation requirements: especially for dry dual-clutch gearbox, because there is no oil immersion to dissipate heat, long-term intense driving or frequent gear shifting will easily lead to overheating, which will affect performance and life. The wet dual-clutch gearbox dissipates heat through oil, which is relatively good, but the cost is high.

High maintenance cost: The clutch plates and other parts of the dual-clutch gearbox are vulnerable parts, which may need to be replaced after a certain mileage, which increases the maintenance cost.

So, friends, which gearbox do you prefer?

　　[Special correspondent of Global Times in the United States, Germany and Canada Xiao Da Qing Mu Tao short room Chen Kang Liu Yupeng] The United States and NATO formally submitted a written reply on bilateral security guarantees to Russia on the 26th. Although the United States and NATO refused to disclose the specific details of the reply, US Secretary of State Blinken made it clear at the press conference that she had rejected Russia’s most concerned request of "not accepting Ukraine to join NATO".

　　In response, the Russian side responded strongly on the 27th, saying that the responses of the United States and NATO indicated that the United States was prepared to confront Russia directly and engage in global confrontation. In the past two days, the United States and its allies have been sending weapons to Ukraine, while constantly rendering that Russia will still "invade Ukraine." US Deputy Secretary of State Sherman insisted that "Russia is ready to use force against Ukraine in mid-February". British Prime Minister Johnson threatened that if Russia "invaded" Ukraine, Britain would send troops to protect its European allies. Many international analysts worry that this kind of hype will not only help solve the Ukrainian problem, but may even push the crisis into the abyss of war. On the 27th, Wang Yi, State Councilor and Foreign Minister of China, said on the phone with Blinken at the request that we call on all parties to remain calm and not to do anything to stimulate tension and exaggerate the crisis. Wang Yi emphasized that one country’s security cannot be at the expense of other countries’ security, and regional security cannot be guaranteed by strengthening or even expanding military blocs.

　　NATO rejects the "red line" drawn by Russia.

　　Russian Deputy Foreign Minister Grushko met with U.S. Ambassador to Russia Sullivan on the 26th, RIA Novosti quoted a statement from the Russian Foreign Ministry on the 27th. During the talks, Sullivan handed over the written reply of the US government to the draft bilateral security guarantee submitted by Russia. However, the Russian Foreign Ministry did not explain the specific content of the US written reply in the statement. The Russian side said that the United States asked Russia to keep the specific content confidential.

　　"The United States has rejected Russia’s ‘ Ukraine is prohibited from joining NATO ’ The core requirements. " The British Broadcasting Corporation (BBC) said that Blinken said at a press conference on 26th that the Biden administration’s position "has not changed", the United States will not give in to Russia’s core demands, and NATO will maintain its open policy for all countries to join the alliance. "The door of NATO will always be open, which is our commitment." Blinken also said that the United States still believes that Moscow is ready for invasion. "There is no doubt that we are taking actions with the same emphasis and strength to strengthen Ukrainian defense and prepare for a rapid and unified response to Russian aggression." However, he also said that he would meet again with Russian Foreign Minister Lavrov in Geneva on Friday to solve the security concerns of both sides, including improving military transparency.

　　"NATO directly rejected Russia’s ‘ Red line ’ " The "Russia Today" website said that 30 NATO member countries jointly recognized the written reply to Russia, and on the 26th, it was also submitted to Russia by the US Ambassador to Russia Sullivan. NATO Secretary General Stoltenberg also said at the press conference on 26th that NATO "will not compromise" on the issue that "Ukraine, Georgia and other former Soviet republics may join NATO". He also said that NATO is still strengthening its presence, including in the Baltic Sea and the Black Sea.

　　Russia will provide weapons to Udong?

　　"The reply of the United States is to go into direct conflict with Russia." Russian newspaper Viewpoint quoted Dzhabarov, a member of the Russian Federal Council, as saying on 27th that Russia would not accept the response of the United States to Russia’s security guarantee proposal, which was unsatisfactory. He said: "The response of the United States shows that the United States wants to go to direct conflict with Russia and prepare for global confrontation." Regarding Stoltenberg’s statement that he would continue to strengthen NATO’s presence in the Baltic and Black Seas, Dzhabarov said: "Stoltenberg is completely insane. He doesn’t know what he’s talking about. I don’t think it is necessary to value him. " Russian Congressman Nikonov proposed: "For the United States and NATO to reject Russia’s core security proposal, we will soon formulate a response measure … … It seems that we will start from the armed Donetsk and Lugansk republics (two republics in eastern Ukraine that declared their independence by themselves — — Editor’s note) Start. "

　　Peskov, Russian Presidential Press Secretary, said on the 27th that Putin had received a reply from the United States to the security proposal, and he would hold consultations with members of the National Security Council. "Let’s not jump to any conclusions." Peskov said that Washington’s reply gave no reason for optimism. Regarding whether Putin will agree to provide weapons to Donbass (the Republic of Donetsk and Lugansk) to counter the United States and NATO, peskov said: "The President is well aware of this view, and he has not made a decision on these proposals. But the suggestions of parliamentarians highlight how angry Russia is. "

　　Russia’s Independent newspaper said that Russian Foreign Minister Lavrov said in a speech in the State Duma on the 26th that Russia would reserve the right to take tough measures against the response of the United States and NATO. He said: "If the United States does not respond constructively and the West continues its aggressive line, then Moscow, as Russian President Vladimir Putin has repeatedly said, will take necessary retaliatory measures." He also said that while some western countries evacuated their personnel from Ukraine, they sent weapons to Ukraine, which was causing "hysterical military fanaticism".

　　Germany and France are different from the United States and Britain.

　　The crisis between Russia and the United States and the West was triggered by the US side’s exaggeration that Russia would "invade Ukraine". Now American officials are still speculating on this topic, but the predicted time point has changed many times. US Deputy Secretary of State Sherman claimed at the video conference of the European Strategic Forum on 26th that the United States insisted that Russia was still preparing to "invade Ukraine". She said: "All the signs we have seen indicate that Russia will use force at some point, possibly between now and mid-February." Sherman also provoked that the Beijing Winter Olympics will be held soon. "If Putin chooses to use force at that time, China leaders will be unhappy. This may affect the timing of Putin’s choice (use of force). " Previously, Bloomberg News of the United States had deliberately spread the false news that "China asked Russia not to invade Ukraine during the Beijing Winter Olympics", which was denounced as a "despicable trick" by a spokesman for the Russian Foreign Ministry, saying that it was "not only a slander and provocation to Sino-Russian relations, but also a deliberate interference and sabotage to the Beijing Winter Olympics".

　　Recently, Britain has also been constantly arching the fire over the Ukrainian crisis. The BBC said that British Prime Minister Johnson said in a speech in Parliament a few days ago that if there is a conflict between Russia and Ukraine, "we will seek to contribute to any new deployment of NATO to protect our allies." However, when asked whether Britain would send troops to Ukraine, Johnson went soft again. He said that no NATO member is ready to send a huge combat force to Ukraine because Ukraine is not a NATO member.

　　Different from the way the United States and Britain play up the crisis and stimulate tensions, European powers such as Germany and France prefer to solve the crisis through diplomacy. "Deutsche Welle" said on the 27th that Biden had publicly warned that if Russia "invaded Ukraine", it would consider directly sanctioning Putin. Earlier, Russia had responded to the provocation of the United States about sanctions against Putin, saying that sanctions against Putin were "equivalent to severing relations between the two countries." According to the report, while Biden publicly threatened to sanction Putin, German Chancellor Angela Scholz and French President Jacques Macron both said that they would use diplomatic means to solve the Russian-Ukrainian crisis.

　　Russia, Ukraine, Germany and France held the "Normandy model" four-party talks in Paris on the 26th. After eight hours of deliberation, Russia and Ukraine agreed to continue to abide by the ceasefire agreement in eastern Ukraine, and a new round of talks was held in Berlin two weeks later. This progress was praised by Germany and France. The French presidential palace said that the difficult talks finally achieved positive results, "we received a good signal." Macron also said that he will hold a telephone conversation with Putin on the 28th. "We will never give up the dialogue with Moscow."

　　Reuters said on 27th that Germany was accused of "betrayal" because it refused to provide weapons to Ukraine like other western countries, and the German government said on 26th that it would provide Ukraine with 5,000 military helmets. This plan was denounced as a "joke" by Kiev Mayor Kritchenko. However, German Defense Minister Lambrecht insisted on 26th that Germany would not send deadly weapons to crisis areas "because we don’t want to aggravate the situation".

　　"Every effort must be made to avoid war"

　　"Will the war begin after the United States and NATO reject Russia’s core security requirements?" RIA Novosti issued such a question on the 27th. In fact, the negative reaction of the United States to Russia’s proposal will not surprise Russia. The report said that the United States promoted the escalation of the situation in Ukraine and even prepared to drag Russia into the war at the expense of Ukraine in order to consume Russia’s strength and weaken the relationship between Europe and Russia. Russia and Europe have long been divided, which is in the interest of Anglo-Saxons. With the help of the Ukrainian issue, the United States can contain Russia and dominate European affairs.

　　"Every effort must be made to avoid war," Russian "Viewpoint" quoted Medvedev, vice chairman of the Russian Federal Security Council, as saying in a joint interview with the media that if there were a direct conflict between Russia and NATO over the Ukrainian issue, "it would be the most tragic and simply catastrophic situation. I hope this will never happen. " He said that the only possibility to avoid war is to reach an agreement. Russia needs security to eliminate the obvious threat that has already formed. If Ukraine joins NATO, new military bases and new offensive weapons will appear near the border with Russia.

　　When answering whether Russia and China will form a military alliance to put pressure on the containment of the anti-American West, Medvedev said that Russia and China do not seek to establish a military alliance, but "the level of relations between the two countries is at an all-time high, which affects the balance of power in the world".

　　On 26th, Wang Yi, State Councilor and Foreign Minister of China, telephoned Blinken at the request, and his position on the Ukrainian issue attracted the attention of the international media. "Foreign Minister China warned Blinken to take Russian security concerns seriously." The German newspaper Sü ddeutsche Zeitung said that Wang Yi called on all parties to remain calm and not to do anything to stimulate tension and exaggerate the crisis. He stressed that all parties should form a balanced, effective and sustainable European security mechanism through negotiations, and Russia’s legitimate security concerns should be taken seriously and resolved.
