Although there are no holidays in the near future, it has entered the summer vacation period, and the students who have been released from the summer vacation are like being released from prison, going home, going out to travel, and some parents taking their newly graduated children to the newly admitted universities for inspection, and so on, etc., etc., and so on, and the transportation industry in these two months has been pushed to the second peak period in addition to the Spring Festival.

Fortunately, the place where Wang Yiyuan is now and Baqing City were originally sister cities, and the distance between the two places is only more than 300 kilometers according to the calculation of the expressway, and they are both southwest economic center cities, so the traffic between the two places is very convenient, and there are many train frequencies.

Wang Yiyuan originally planned to take a bus if she really couldn't buy a train ticket for the return trip, the bus fare is about the same as the bullet train, a little cheaper than the high-speed train, but the time spent on the road is almost doubled. However, the advantage is that there are many buses, basically every half an hour, but I don't have to worry about not being able to buy tickets.

I have made the worst psychological plan, and I didn't check the nearest flight on the Internet, so I went directly to the high-speed rail station to take a look, and there were still tickets for the nearest flights, and Wang Yiyuan happily bought tickets and got on the bus.

I feel like I've been lucky lately! Not only have I not encountered anything unlucky, but many things have even gone smoothly.

But......

However, the friends around him have had accidents one after another, is it because their bad luck has been transferred? Is this considered that they have hurt their friends?

As soon as she thought of this, Wang Yiyuan's excitement cooled down.

I don't know how Chen Yang has been doing recently, there has been no news for almost a month. Even if you have something to do, it's not too difficult to take a minute or two a month to make a phone call to report your safety, I don't know if my friends will be worried? Men are really heartless animals!

Wang Yiyuan thought angrily.

High-speed rail fares are expensive, but they are fast and comfortable.

Sitting on the seat and looking at the different scenery flashing outside the window, Wang Yiyuan was very proud of the motherland in her heart.

There are always people who criticize our country's scientific and technological level for not being good, blindly worshipping foreign technology, and what kind of German industry, Japanese electronic products, American and so on, in fact, are just a blind eye. As everyone knows, our country has developed rapidly in industrial science and technology in recent years, and many of them have reached the world-class level, and even reached the world's leading level in some projects.

A few years ago, Saudi Arabia, which is rich in oil resources, conducted a global tender for a phosphate fertilizer project in order to diversify its own resource market. With a value of more than $450 million, it was one of the largest tenders in the world at the time, attracting the attention of major companies around the world.

Chinese companies also participated in the bidding for the project, but in Saudi Arabia, which advocates European and American technology, the competence of Chinese companies is highly questionable. However, after many investigations, coupled with the fact that China has the only core technology in the world - anhydrous hydrogen fluoride extraction technology, this technology can bring about 200 million US dollars of additional income to the Saudi government every year, which makes Saudi Arabia completely unable to resist. In the end, China's company stood out among many competitors and successfully won the bid.

This technology is not only the leading level in the world, but the only one! South Africa once coveted this technology and wanted to buy it from our country, but the high price offered by our side that does not accept bargaining discouraged the other side. However, in the following year, the other party searched all over the world, and found that this technology is indeed only owned by our country, and had to send out the willingness to buy again, and in the case that our company increased the total price of the original sale of the technology by 20% due to the increase in the price of labor and materials, South Africa decided to buy and reached a final cooperation with us.

Recall that many years ago, because of the low degree of economic development and backward industry in our country, many of our technologies at that time relied on imports, and the companies that sold technology abroad were all above the top, never looking at us squarely.

Nowadays, China's scientific and technological development is changing with each passing day, and now many technologies have reached the world's leading level, but foreign companies are shy to seek cooperation with us.

For example, wind tunnels. Wind tunnel is a kind of pipe-like experimental equipment that generates and controls the airflow in an artificial way, is used to simulate the flow of gas around the aircraft or entity, and can measure the effect of the airflow on the entity and observe physical phenomena, it is one of the most commonly used and effective tools for aerodynamic experiments, and is an indispensable part of the development of the aircraft.

Wind tunnels not only play an important role in the research and development of aviation and aerospace engineering, but also are indispensable in transportation, housing construction, wind energy utilization and other fields with the development of industrial aerodynamics.

Previously, the United States' wind tunnel technology has always been the best, but this dominant hegemony has finally been broken by China.

JF-12 wind tunnel is the first super wind tunnel with independent intellectual property rights of Chinese, its research and development was successful and put into use, is currently the world's first in the world of the same type of hypersonic experimental equipment in the world, foreign media believe that in the development of hypersonic weapons, China has actually been ahead of the United States.

With this technology, Jiang Zonglin, a researcher at the Institute of Mechanics of the Chinese Academy of Sciences, won the 2016 American Institute of Aeronautics and Astronautics (AIAA) Ground Test Award from the American Institute of Aeronautics and Astronautics, becoming the first Asian scholar to win the award in more than 40 years.

The technical problems that the United States has been plagued by for more than 20 years have been solved in China and put into practical application, which makes European and American countries all envious, and even some companies have repeatedly proposed to China for purchase or cooperation, but considering military reasons, our side did not hesitate to refuse. For the Chinese people, what a puff of pride!

Another example is the high-speed train that Wang Yiyuan is currently taking.

China's high-speed railway uses ballastless track, which is the most advanced track technology in the world today, which can reduce maintenance, reduce dust and beautify the environment. The ballastless track can play a role in shock absorption and decompression, and improve the comfort of the ride.

Some foreign friends have done a coin test on Japan's high-speed rail and China's high-speed rail for fun. On Japan's high-speed rail, a standing coin can not fall for a long time, but Japan's high-speed rail cannot do it.

Some time ago, a piece of news caused a sensation around the world.

China's two high-speed railways have successfully met trains with a speed of more than 420 kilometers per hour. The two high-speed trains were driving in opposite directions, passing by, and the relative speed of the train reached a terrifying 840 kilometers at the time of the meeting, which shocked the world. This speed and safety have staggered Japan, which was the first to develop and use high-speed rail.

Of course, due to technical, cost and safety considerations, although the design speed of China's high-speed rail exceeds 400 kilometers per hour, the actual operation is generally maintained at more than 300 per hour, which is also the most economical and safest operating speed at present.

Wang Yiyuan loves her country, but she is not an angry youth, she also admits that other countries have many good things, and at present, China is still lagging behind others in many fields. However, she is very objective, the founding of the motherland has only been a few decades now, and it is already very proud of the growth rate of scientific and technological development, industrial development, and economic development.

Why do some Western countries always talk about our country all day long? It is not because the speed of our country's development has made them feel threatened. China is a peace-loving country, and this threat does not come from the military, but from the economy, but also from the development of science and technology and the equipment manufacturing industry.

For the development of a country, it must have its own core technology to master intellectual property rights, which is the real weapon of a great power and will not be controlled by others.

China's scientific and technological workers and senior engineers have been working hard, as Chinese people, we should give our country more confidence and support, right?

Wang Yiyuan sat in her seat, constantly thinking of the proud side of our country's development, and she was moved to tears.
