Chen Zhou dragged the compressed package into a specially created folder, and then started to decompress the compressed package.

"Huh? Password?"

Chen Zhou did not expect that Dean Yang also encrypted the compressed package.

But if you think about it carefully, generally speaking, such topics are projects of the Institute of Physics and have a certain degree of confidentiality, which is normal.

Chen Zhou took out his mobile phone and was about to call Dean Yang to ask for the password.

However, before the call was dialed, Dean Yang sent another txt file.

After Chen Zhou received it, he opened the document and found the decompression code of the compressed package [dzs1].

Enter the decompression code and the compressed package will be decoded smoothly.

Opening the unzipped folder, Chen Zhou couldn't help but be stunned.

Good guy, is Dean Yang afraid that he will be too busy at home during the summer vacation? Or is he worried that he will be obsessed with hail conjecture and unable to extricate himself?

In the folder named "Principles and Applications of Intense Pulsed Particle Beam", there are dozens of folders of various sizes, and there are also folders within the folder...

"No wonder it took so long to download. There are too many subject materials for this project, right?" Chen Zhou muttered in his heart, and opened a document by sliding the mouse on his hand.

[High power particle beam and its applications]

Chen Zhou looked at it carefully.

High-power particle beams are generally called strong-current relativistic particle beams, including electron beams and ion beams.

This is a concept that is not that old.

Chen Zhou remembered that he had seen in a document that in the 1950s, the concept of strong current relativistic electron beams was proposed.

By the end of the 1980s, thanks to the pioneering work of Professor Martin from the UK, the practical application of strong-current relativistic electron beams became possible.

However, the research background of these thirty years was under the changing international situation.

In the early 1960s, Professor Martin and his team at the British Atomic Weapons Research Center first suggested using pulse power technology to generate high-power electron beams.

And successfully applied transmission line technology to the research of pulse power, thus creating a new situation in pulse power technology.

It was also from this time that high-power electron beam accelerators began to develop as a simulation source for nuclear weapons effects.

In the late 1970s, due to the proposal of the particle beam inertial confinement fusion scheme, high-power particle beams began to develop towards higher power levels.

In the past few years, major laboratories of major international powers have built a large number of generating devices.

China's domestic research on high-power electron beams began with the development of pulse x-ray machine technology in the early 1960s. In the late 1960s, research on nanosecond pulse high-voltage technology began.

It was not until the 1970s that we officially turned to the development of high-power pulsed electron beam accelerators.

Now, about high-power electron beam and ion beam technology and their application in many scientific research fields.

Such as nuclear explosion simulators, high-energy flash x-ray photography, internal electromagnetic pulse research, inertial confinement fusion, excitation of free electron lasers and high-power gas lasers, etc.

Emerging disciplines derived from it include radiation-resistant electronics, relativistic electronics, strong beam physics, etc.

In general, high-power particle beam is currently a relatively active cutting-edge science and technology, and it is also an important technical basis for strong laser research.

Withdrawing his thoughts, Chen Zhou continued to look at the documents in front of him.

Until noon, Chen Xiao came to knock on the door and called him to eat.

Chen Zhou came back to his senses from the world of particle beams.

Chen Zhou didn't get up in a hurry, he just turned around and said to Chen Xiao, coming over immediately.

Turning his head, Chen Zhou looked at the literature on the computer in front of him and pondered slightly.

For him, the difficulty of Dean Yang's topic this time was a bit too high.

Although Dean Yang said that he would only be responsible for processing the data of the project and give full play to his strengths in rigorous mathematical calculations.

But Chen Zhou would not foolishly think that he just needed to pull some formulas and calculate the data to solve the problem.

Moreover, this is not his style.

Now that you have joined the research group, you must do your best.

Chen Zhou's current mentality is optimistic and positive. He doesn't know when he started to gradually change his mentality.

After thinking about it, Chen Zhou felt that it was still necessary to make a plan when things piled up like before.

The advantage of this is that firstly, you can know the specific progress of everything, and secondly, you can allocate time reasonably.

"Xiaozhou, come and eat!"

"good!"

After sorting out the notes he had taken while reading the literature, Chen Zhou stood up and walked out of the room.

Zhang Hongying made another sumptuous lunch.

When eating, Chen Zhou felt that he had been eating, but the amount of food in the bowl didn't seem to decrease?

Sure enough, children at home can only eat fatter than eating fatter.

Chen Zhou couldn't help but worry that he would have a double chin when he went back after this summer vacation.

After eating, Zhang Hongying and Chen Jianguo went to work.

The tasks of cleaning up the dishes and washing the dishes were respectively undertaken by Chen Zhou and Chen Xiao.

"Brother, there's a question I'm not very good at. Can you explain it to me later?" Chen Xiao, who was washing the dishes, spoke to Chen Zhou.

Chen Zhou nodded: "Okay, is it the book you opened?"

Chen Xiao: "That's the book, I circled that question."

"I'll take a look first. Come over here after you've finished washing the dishes."

"good."

Chen Zhou walked to the table, picked up the information that Chen Xiao had spread out on the table, and started reading.

On the information, Chen Xiao circled a question in red pen.

It's a proof question, but it's not a long question.

[Suppose n is a positive integer, a1, a2,..., an, b1, b2,..., bn, a, b are all positive real numbers, satisfying ai≤bi, ai≤a, i=1,2,...,

n, and b1b2···bn/a1a2···an≤b/a.】

[Proof: (b11)(b21)···(bn1)/(a11)(a21)···(an1)≤(b1)/(a1).】

After Chen Zhou read the question, he already had an idea.

After reading the question again, Chen Zhou smiled softly. This question was indeed a bit difficult for Chen Xiao, a quasi-high school student who had just graduated from the high school entrance examination.

At this time, Chen Xiao had finished washing the dishes and came over.

He picked up a piece of draft paper on the table and handed it to Chen Zhou: "Brother, I can only calculate this question so far. Take a look at it. Is the previous idea correct?"

Chen Zhou took the draft paper and looked at it.

Well, this guy is not bad, and the previous idea is correct.

It is already very good to be able to answer this step.

"Yes, it's very difficult for you to be able to calculate the difficulty of this question. It's even better than a high school student. It's amazing!" Naturally, Chen Zhou was not stingy with his praise.

Hearing Chen Zhou's compliment, Chen Xiao unconsciously grinned.

He still appreciates his brother's praise.

Chen Zhou naturally noticed Chen Xiao's appearance. He smiled and said, "Don't be proud. Come, let me help you sort out your thoughts."

After saying that, Chen Zhou picked up the pen and started writing on the draft paper, following Chen Xiao's calculations.
Chapter completed!
