After coming out of Dean Zhou's office, Chen Zhou opened the white envelope.

Inside is a letter of invitation.

When he saw the payment, Chen Zhou was slightly surprised.

The writer of this letter turned out to be one of his reviewers.

The professor Tao Zhexuan who posted him on his blog again and again.

There was a sentence in the letter, but Chen Zhou couldn't help laughing.

Tao Zhexuan wrote in the invitation letter: "I have posted so many blogs, no one has ever been able to let me take the initiative to delete them, but you have done it. I'm never going to say anything mathematically about anything that is unlikely to be proven by current technology, it's. ”

Chen Zhou can understand Tao Zhexuan's feelings when he wrote this paragraph, which is probably very sour.

It's just that Chen Zhou never figured out how Tao Zhexuan had anything to do with MIT's invitation letter?

It stands to reason that Tao Zhexuan, a Filipino award boss, would not have written an invitation letter to an academic conference in person anyway?

Shaking his head slightly, without thinking about it anymore, Chen Zhou folded the invitation letter and put it back in the envelope.

Then, head towards the library.

Along the way, Chen Zhou felt that there was more attention.

For no other reason, it was all the white envelope in his hand.

The MIT emblem on the envelope is really glaring.

Especially for some students on the campus of Yan University, who are applying for offers.

What's going on?

An offer from MIT?

It doesn't look like it, doesn't it mean that Big Brother Chen Zhou has been determined to be jointly trained by Yan University and MIT?

Could it be that MIT will write letters separately for students who are jointly trained?

In the midst of such attention and speculation, Chen Zhou walked back to the library.

Coming to the study area of the library, it is much better.

Although some time ago, there was a siege of the self-study area, but now the students have resumed their self-study.

After all, exam preparation is crucial.

Walking to his place, as soon as Chen Zhou sat down, he saw Yang Yiyi's eyes next to him.

Chen Zhou thought she was asking what was going on with the envelope in her hand, so she explained: "What Dean Zhou gave me was an invitation letter from the Massachusetts Institute of Technology, inviting me to give a 30-minute presentation. ”

"Oh, this simulated situation, you can look at it......" Before Yang Yiyi finished speaking, she raised her head and looked at Chen Zhou in surprise.

She originally planned to take the computer to Chen Zhou, but at this moment, the hand holding the computer stopped in mid-air.

"Uh...... I thought you were going to ask me why I went......" Chen Zhou explained.

Hearing this, Yang Yiyi put the computer in front of Chen Zhou, took the envelope that Chen Zhou had just placed on the table, and looked at it carefully.

Yang Yiyi just wanted to open the envelope and look at the invitation letter inside, but her hand paused.

She tilted her head slightly, looked at Chen Zhou, and before she could speak, Chen Zhou, who noticed her movements, had already said first: "The invitation letter is inside, you can open it and take a look." ”

A smile appeared on the corner of Yang Yiyi's mouth, opened the envelope, took out the invitation letter and looked at it.

Chen Zhou looked at Yang Yiyi with a smile, waiting for a wave of praise.

did not disappoint Chen Zhou, Yang Yiyi put down the envelope and looked at Chen Zhou, with a look of adoration in her eyes: "Happy, you are so good! Thirty-minute report, an undergraduate, is really amazing!"

Chen Zhou's psychological expectations were satisfied.

Yang Yiyi's voice, although not loud, still attracted the attention of many people.

They all stared closely at the invitation letter in Yang Yiyi's hand.

This is the symbol of the big guy!

After a while, helping Chen Zhou put away the invitation letter, Yang Yiyi pushed the computer in front of Chen Zhou, and finished the words that had just been interrupted: "Take a look at this simulated situation." As last time, a simulation of a self-purging reflective particle beam diode is performed based on the experimental data you processed. ”

Chen Zhou looked up at the simulated data on the computer.

Yang Yiyi reprocessed the experimental data on the basis of the experimental data he processed.

According to the typical experimental results of self-pinch reflected particle beam diodes in the literature, combined with the comparison of data parameters between the two diodes, the reasonable optimization is carried out.

After a brief review in his heart, Chen Zhou said: "If our calculations are correct, the first experiment can achieve such an effect." The experiment with the self-pinch reflected particle beam diode was about two times to get the results we wanted. ”

Yang Yiyi nodded: "I think so too." But I referred to the experiment of the Northwest Nuclear Institute, and their experimental data and the data calculated by the simulation are quite different. ”

Chen Zhou frowned slightly: "It stands to reason that this shouldn't be the case." ”

Yang Yiyi brought over a piece of scratch paper with some of her own analyses on it.

After Chen Zhou finished reading it, he said, "Do you think it's because of the accelerator itself?"

Yang Yiyi pointed to a line of words on the scratch paper and explained: "Because the 'Flash No. 2' is a low-impedance strong current pulsed electron beam accelerator with the largest electron beam intensity in China, the ideal effect of its experiment is far from being comparable to this too old guy in our current laboratory." ”

Chen Zhou couldn't help but smile slightly when she heard Yang Yiyi say "old guy", this word is probably taught to her by Peng Jia.

Moreover, from the mouths of Lin Xiaoen and Ma Zihao, he also heard it.

Because this particle accelerator in the laboratory has been many years old, it is still a product of the last century.

It is said that in another year or two, he will be honorably retired.

That's why Peng Jia and the others call this accelerator an old guy.

Yang Yiyi looked at Chen Zhou and wondered, "What are you laughing at?

Chen Zhou still smiled and said: "No, it's not your understanding, it's that as soon as you say the old guy, it's hard for me to imagine that my family Yiyi can actually say this word." Ay...... I was wrong......"

Before Chen Zhou finished speaking, he felt what it means to be happy and unhappy.

Yang Yiyi's hands kept moving, and she said seriously: "Classmate Chen Zhou, discuss the problem well." ”

Chen Zhou nodded again and again and begged for mercy, if it weren't for the library, Yang Yiyi would have screamed loudly.

"Hmph!" Yang Yiyi snorted coldly and let go of her hand.

If it weren't for the library, she would definitely have to work harder.

Chen Zhou rubbed his pinched aching thighs, looked at the scratch paper, and said softly: "Can you find the parameters of 'Flash No. 2' from the literature? ”

Yang Yiyi immediately understood what Chen Zhou meant, since he referred to the experimental data of "Flash No. 2", the deviation was large.

Then, based on the accelerator "Flash-2", the processed experimental data was used to simulate and calculate the self-pinch reflected particle beam diode.

Comparing the experimental data of the Northwest Nuclear Institute, it will show where the problem is.

"I'll look for it right away. Yang Yiyi said, and began to look up relevant literature.

Chen Zhou smiled slightly, Yiyi was really as smart as himself, and he could understand it at one point.

"You look for it from the 'Flash No. 2', and I'll check from the Northwest Nuclear Institute. After Chen Zhou finished speaking, he also began to tap on the keyboard on the computer, searching for relevant literature.

In general, the detailed parameters of the equipment of such a confidential scientific research institute are difficult to find.

But the approximate equipment parameters can still be found.

Just as Chen Zhou was busy looking up the equipment parameters of the "Flash No. 2" accelerator, his mobile phone vibrated again.
