Chen Zhou dragged the archive into a specially created folder, and then began to unzip the package.

"Huh, password?"

Chen Zhou didn't expect that Dean Yang also encrypted this compressed package.

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

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

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

After Chen Zhou received it, he opened the document, and inside was the decompression code [DZS1] of the compressed package.

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 idle at home during the summer vacation, or is he worried that he will be addicted to hail conjectures and will not be able to extricate himself?

In the folder with the file name "Principles and Applications of Intense Pulse Particle Beams", there are dozens of folders of all sizes, and there are folders in folders......

"No wonder I've been downloading for so long, and there are too many subject materials for this project, right?" Chen Zhou muttered in his heart, and with a swipe of the mouse in his hand, he opened a document.

【High Power Particle Beam Extreme Applications】

Chen Zhou took a closer look.

High-power particle beams, commonly referred to as strong current relativistic particle beams, include electron and ion beams.

It's a not-so-old concept.

Chen Zhou remembers seeing in a literature that in the fifties of the last century, the concept of strong current relativity electron beam was proposed.

By the end of the eighties, the groundbreaking work of Professor Martin in the United Kingdom made it possible to use the strong current relativity electron beam.

However, the background of these 30 years of research is under the changing conditions of the international situation.

In the early sixties, Professor Martin and his group at the UK's Centre for Atomic Weapons Research were the first to propose the use of pulsed power technology to generate high-power electron beams.

And the successful application of transmission line technology to the study of pulse power, thus creating a new situation of pulse power technology.

It was also at this time that high-power electron beam accelerators began to develop as a source for simulating the effects of nuclear weapons.

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

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

The research on high-power electron beam in China began with the development of pulsed X-ray machine technology in the early sixties, and the research on nanosecond pulsed high-voltage technology began at the end of the sixties.

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

Now, high-power electron and ion beam technologies and their applications in many fields of scientific research.

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

There are also emerging disciplines such as radiation-hardened electronics, relativistic electronics, strong beam physics, and so on.

In general, high-power particle beams are a relatively active frontier science and technology, and it is also an important technical basis for the research of high-power lasers.

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

It wasn't until noon that Chen Xiao came over and knocked 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 rush to get up, just turned around and said to Chen Xiao and came 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 much.

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

But Chen Zhou will not be stupid to think that as long as he pulls some formulas and calculates the data, it will be solved.

And, that's not his style either.

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

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

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

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

"Xiaozhou, come and eat!"

"Good!"

After sorting out the notes made by reading the literature, Chen Zhou got up and walked out of the room.

Zhang Hongying made another sumptuous lunch.

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

Sure enough, children at home, in addition to eating fat, only eat fatter.

Chen Zhou couldn't help but worry, after this summer vacation, when he went back, would he grow a double chin?

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

The task of cleaning up the dishes and chopsticks and brushing the dishes was undertaken by Chen Zhou and Chen Xiao respectively.

"Brother, I don't know a question very well, can you explain it to me later?" Chen Xiao, who was washing the dishes, said to Chen Zhou out loud.

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

Chen Xiao: "It's that book, and I drew a circle on that question." ”

"I'll take a look first, you can brush the bowl and come here. ”

"Good. ”

Chen Zhou walked to the table, picked up the book that Chen Xiao spread out on the table, and read it.

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

A proof question, the question is not long.

[Let n be 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: (B1+1)(B2+1)··· (bn+1)/(a1+1)(a2+1)··· (an+1)≤(B+1)/(A+1)。 】

After reading the topic, Chen Zhou already had an idea.

After reading the question again, Chen Zhou smiled softly, this question is indeed a little difficult for Chen Xiao, a prospective high school student who has just graduated from the high school entrance examination.

At this time, Chen Xiao had already finished brushing the bowl and walked over.

He picked up a piece of scratch paper on the table and handed it to Chen Zhou: "Brother, I can only count this question here, take a look, is the previous idea correct?"

Chen Zhou took the scratch paper and looked at it.

Well, this kid is not bad, the previous idea is right.

It's good to be able to answer this step.

"Yes, the difficulty of this question, you can calculate this, it's already very rare. It's even better than a high school student, it's amazing!" Chen Zhou naturally didn't skimp on his praise.

Hearing Chen Zhou's praise, Chen Xiao unconsciously grinned at the corners of his mouth.

For his brother's praise, he is still very useful.

Chen Zhou naturally noticed Chen Xiao's appearance, and he smiled and said, "Don't be proud. Come, I'll help you get your thoughts straight. ”

After speaking, Chen Zhou picked up the pen and began to write on the scratch paper, followed Chen Xiao's calculations.

Chen Xiao restrained his expression and looked at it seriously.
