"She comes from a wealthy background, I am a small family, and I am not worthy of her. Pen, fun, pavilion www. biquge。 info" Su Changan said with a wry smile, "Yuanyuan, in fact, I envy you very much, I met Zhang Daoming in the best years." Although many people say that he will not wake up, I know that he will wake up, and he will wake up for you. ”

When I was a teenager, I was really lucky to meet someone I liked.

At that time, people and hearts were so simple, like crystal clear droplets in the sun, rolling just to get closer to each other until they became one.

When I was a teenager, I didn't have the utilitarianism and cowardice that I would get when I grew up, only an indomitable love.

"That girl, she may not care about this......" Ye Congyuan whispered something that he was not sure of. She doesn't care about that, but that doesn't mean everyone thinks the same way as her.

"When you grow up, love is no longer a matter of two people, but a matter of two families." Su Changan replied, "Yuanyuan, you don't have to worry about me, and you don't need to persuade me, I know how to do it." ”

Ye Congyuan failed to persuade Su Changan in the end, and she couldn't even ask who the girl he liked was.

After hanging up the phone, she held the phone and looked up at the blinding white light.

If the world were white, people wouldn't have too many troubles, and the world wouldn't have too many wars.

Ye Congyuan himself also has a lot of troubles, missing Zhang Daoming, the sisterhood between him and Ye Zhengyu, and the worry of being thoroughly investigated by the intelligence officers.

If it is said that there were 100 intelligence officers in Beijing at the beginning of the protective cover, there are at least 3,000 now.

The protective shield could not be broken, and those intelligence officers could only enter the city of Beijing, find out the chief designer of the protective shield, and then try to bring it back.

Ye Congyuan didn't know how long it would take to find her. She hopes to at least let her finish her undergraduate studies and complete her four years of undergraduate studies in peace.

"Yuanyuan, come on, help me see this formula." Elder Qin greeted Ye Congyuan cordially.

Ye Congyuan came back to his senses, put the phone in his pocket, put a smile on his face again, and walked towards Qin Lao.

Time flies, and in a blink of an eye, the summer vacation is over and school is at school.

Ye Congyuan has gained a lot in the big laboratory, and she, together with a few professors and a few old experts, has promoted the rapid development of the maglev train.

However, after such a long time of understanding the maglev train, and also after the initial passion, Ye Congyuan had hidden worries in his heart.

Although the maglev train is developing rapidly, the prospect is not optimistic.

First, the maglev system must be supplemented by electromagnetic force to complete the levitation, guidance and drive, so the safety of the train in the case of power failure has become a big problem; Second, when running at high speeds, the stability and reliability of the train also need to be tested in practice for a long time. Third, because the train needs to be suspended at a specific height when running, the requirements for the flatness of the line and the subsidence of the roadbed are very high; Fourth, it is necessary to avoid the impact of strong magnetic fields on the human body and the environment.

Ye Congyuan has studied ultrasonic drilling and protective covers, and it can be said that nothing can stump her in terms of energy supply, so the possibility of the maglev train losing power is not a problem for her. As for the safety of high-speed trains, with a high-level protective cover, it is not a problem. The last influence of the magnetic field, the infrared alarm device she studied has a law to follow, and it has also been solved.

The difficulty lies in the third point, the maglev train has high requirements for the flatness of the line and the sinking of the foundation. Ye Congyuan can't find a solution to these problems in the short term - even if she finds a solution, it is impossible for the country to abandon the high-speed rail and reinstall the maglev train, right?

In this way, it should be considered by the world, with high-speed rail, magnetic levitation is not so important, and it can even be regarded as chicken ribs. Although the speed of high-speed rail is not as good as that of maglev trains, it is not much slower, and the cost is much lower, which is really better than maglev trains.

To put it bluntly, the current research on maglev trains, in Ye Congyuan's view, is no longer necessary. Just some of the core research in magnetic levitation, which is very useful for aerospace and aviation.

But with such a big laboratory and so many people, everyone has devoted their whole lives to the maglev train, if they are suddenly told that they should give up, will they be able to accept it?

is Professor Jiang and Qin Lao, both of them are open-minded, but their research on maglev trains is more persistent than ordinary people. And what about the others?

Ye Congyuan sighed thinking about it, there were only two words for "give up", but it was as heavy as a thousand pounds to say it.

Who wants their life's research to be in vain? Who wants to work hard all their lives and end up with a bamboo basket to draw water?

She laughed again as she thought about it, and secretly sighed that she was worried about the sky. Even if the development of maglev trains continues, it is close to the end of practicality, but I am afraid that no one will believe it.

Besides, as she thought, this research is still helpful for aerospace after all, and it can be applied in many fields, and she shouldn't be beaten to death with a stick.

Ye Congyuan thought about it and felt a little bored and helpless, so she put her mind on the car she had been thinking about since she entered Professor Jiang's laboratory, and she felt that the time was suitable for her own research.

Since reading all the materials on levitation technology, she tends to prefer light levitation, sound levitation and even air levitation, which is not magnetic levitation anyway.

"Yuanyuan, what are you doing in a daze?" A voice pulled the contemplative Ye Congyuan back to reality.

Ye Congyuan came back to his senses and said in a daze, "I want to study light levitation." ”

"Oh?" Professor Jiang walked over, "Are you interested in light levitation?" ”

Ye Congyuan nodded, "I think it's better than the prospect of light levitation." ”

"If you're interested, go research it." Professor Jiang thought for a while and said, "The maglev train is still in the testing stage, and there is no very important research left, so you can develop your own hobbies." …… If you encounter any problems, you will come to discuss with us. ”

If it was in the past, he would definitely not want Ye Congyuan to be so half-hearted. But after getting along for so long, he found that Ye Congyuan was really talented in levitation technology. He even faintly had a sense of expectation, if there were no shackles, where could Ye Congyuan go?

Ye Congyuan has eclectic innovative ideas, but what she lacks is a deep technical background. Although she has read all the materials, the technology is bypassable, and some books are not maglevit, but they can be used. Ye Congyuan memorized a lot of books, but it was impossible to say that he had memorized all the relevant books and could use them freely.

But what Ye Congyuan lacked was what they had. They can stand behind Ye Congyuan, give her these technical guidance, and support her to make things that are impressive.
