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

Inside is an invitation letter.

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

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

The Professor Terence Tao who posted him again and again on his blog.

There was a sentence in the letter that made Chen Zhou couldn't help but laugh.

Tao Zhexuan wrote in the invitation letter: "I have posted so many blogs, and no one has ever asked me to delete them on my own initiative, but you did it. I will never again say something in mathematics that is unlikely to be

The current technology proves nonsense, this is nonsense.”

Chen Zhou can understand Tao Zhexuan's feeling when he wrote this paragraph, which was probably very sad.

However, Chen Zhou never understood how Terence Tao was related to the invitation letter from MIT?

It stands to reason that it is impossible for a big figure like Teresa Tao to personally write invitation letters to academic conferences anyway?

Shaking his head slightly and thinking no more, Chen Zhou folded the invitation letter and put it back in the envelope.

Then, walk towards the library.

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

The reason is none other than the white envelope in his hand.

The MIT logo on the envelope is really eye-catching.

Especially for some students on the Yanda campus who are applying for offers.

What's going on?

An offer from MIT?

It doesn’t look like it, doesn’t it mean that Mr. Chen Zhou has been confirmed to be jointly trained by Yanda and MIT?

Could it be said that MIT will write separate letters to jointly trained students?

Amid such attention and speculation, Chen Zhou walked back to the library.

When we came to the self-study area of ​​the library, it was much better.

Although there was a siege on the self-study area some time ago, the students are now back to self-study.

After all, preparing for exams is crucial.

When Chen Zhou walked to his seat and sat down, he saw Yang Yiyi's eyes looking over at him.

Chen Zhou thought she was asking what happened to the envelope in his hand, so he explained: "What Dean Zhou gave me was an invitation letter from MIT, inviting me to give a thirty-minute report.

.”

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

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

"Uh... I thought you were going to ask me what I was doing..." 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.

Just when Yang Yiyi was about to open the envelope and read the invitation letter inside, her hand paused.

She tilted her head slightly and looked at Chen Zhou. Before she could speak, Chen Zhou, who noticed her movements, had already said, "The invitation letter is inside. Open it and take a look."

Yang Yiyi showed a smile, opened the envelope, took out the invitation letter and read it.

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

Chen Zhou was not disappointed. Yang Yiyi put down the envelope and looked at Chen Zhou with admiration in her eyes: "Happy, you are great! A thirty-minute report for an undergraduate student is really amazing!"

Chen Zhou's psychological expectations were met.

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 a boss!

After a while, Yang Yiyi helped Chen Zhou put away the invitation letter. Yang Yiyi pushed the computer in front of Chen Zhou and finished what he had just interrupted: "Take a look at this simulation situation. Just like last time, based on the results you processed.

Experimental data, simulation calculations for self-pinch reflective particle beam diodes.”

Chen Zhou raised his head and looked at the simulated calculation data on the computer.

Yang Yiyi reprocessed it based on the experimental data he processed.

Reasonable optimization was carried out based on the typical experimental results of self-pinch reflective particle beam diodes in the literature, combined with the comparison of data parameters between the two diodes.

After briefly reviewing it in his mind, Chen Zhou said: "If there is nothing wrong with our calculations, the first experiment can achieve this effect. Then the experiment on the self-pinch reflective particle beam diode can achieve our results in about two times."

Desired results.”

Yang Yiyi nodded: "I think so too. But I referred to the experiments of the Northwest Nuclear Institute. The deviation between their experimental data and the simulated calculation data is relatively large."

Chen Zhou frowned slightly: "Logically speaking, it shouldn't be like this."

Yang Yiyi took over a piece of draft paper with some of her own analysis on it.

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

Yang Yiyi pointed to a line of words on the draft paper and explained: "Because 'Flash No. 2' is a low-impedance high-current pulsed electron beam accelerator with the highest electron beam intensity in China, the ideal effect of its experiment is far from ours."

This old guy in the laboratory can compare."

When Chen Zhou heard Yang Yiyi say "old guy", he couldn't help but smile. This word was probably taught to her by Peng Jia.

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

Because the particle accelerator in the laboratory is quite old and is still a product of the last century.

It is said that in a 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 asked doubtfully: "Why are you laughing? Is my understanding wrong?"

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

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

Yang Yiyi kept moving her hands and said seriously: "Classmate Chen Zhou, discuss the problem carefully."

Chen Zhou nodded repeatedly and begged for mercy. If Yang Yiyi hadn't been in the library, he would have screamed very loudly.

"Humph!" Yang Yiyi snorted coldly and loosened her hand.

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

Chen Zhou rubbed his painful thigh, looked at the scrap paper, and said softly: "Can you find the parameters of 'Flash No. 2' from the literature? Just a rough estimate will do."

Yang Yiyi immediately understood what Chen Zhou meant. Since it was based on the experimental data of "Flash No. 2", the deviation was relatively large.

Then use the processed experimental data to simulate the self-pinch reflective particle beam diode based on the "Flash 2" accelerator.

If we compare it with the experimental data of the Northwest Nuclear Institute, we can see where the problem lies.

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

Chen Zhou smiled slightly, Yiyi was indeed as smart as himself, and could figure it out.

"You look for it from the 'Flash No. 2' side, and I'll look it up from the Northwest Nuclear Institute." After Chen Zhou finished speaking, he also started typing on the keyboard on the computer to search for relevant literature.

Generally speaking, it is difficult to find detailed parameters for equipment in confidential scientific research institutes like this.

However, the general equipment parameters can still be found.
