Volume 1: Student Life Chapter 233: Starting from Reverse
Putting down the work in his hands, Chen Zhou took out his vibrating cell phone.
Could it be that President Zhou forgot to tell us something?
When Chen Zhou was confused, he saw the incoming call notification on his mobile phone.
It wasn't Dean Zhou calling, it was Wu Xiping calling.
Chen Zhou frowned slightly. What could Professor Wu want to talk to him about now?
Could it be that he was congratulating himself for giving a 30-minute report?
Shaking his head, Chen Zhou felt that Wu Xiping shouldn't be so boring.
Standing up, Chen Zhou prepared to go out to answer the phone.
But before he could take two steps, the phone was hung up.
After thinking about it, Chen Zhou sent a message to Wu Xiping, asking what was going on, and also said that he was in the library and did not mean to ignore the call.
Then Chen Zhou put away his phone and returned to his seat.
Compared to calling Professor Wu back, Chen Zhou would rather go back to searching for literature.
What Chen Zhou hates most is having his work experience suddenly interrupted.
Refocus our attention on the research paper of the Northwest Institute of Nuclear Research on the "Flash 2" accelerator.
Chen Zhou studied it carefully and classified and recorded some experimental details and data.
However, some parameters of the "Flash 2" accelerator are pitifully few, and it can even be said that they are not included in the paper at all.
Chen Zhou wrote some of the content on draft paper.
Some are recorded in word documents.
After all, he really couldn't draw processes like the explosive electron emission from the diode cathode, beam pinching, virtual cathode formation, electron beam reflection, and ion beam acceleration and extraction.
After scanning a document, Chen Zhou picked up the draft paper in his hand, compared it with the content organized in Word, and fell into deep thought.
"Here are the parameters of the diode, and here are the parameters ..."
"The peak beam intensity of the diode is 480kA, and the peak power can reach 206GW..."
"Well, Northwestern Nuclear Research Institute calculated the total beam current intensity of the diode and the beam current intensity of the high-power ion beam produced based on the measured gap voltage. There is also the measured total beam current intensity of the diode and the ion beam current intensity measured using the biased Faraday cage array. This is a comparison chart..."
"We have both experimental measurement data and theoretical calculation results. If that's the case..."
Chen Zhou made up his mind instantly and knew what to do.
Chen Zhou tilted his head slightly, looked at Yang Yiyi, and asked softly: "Yiyi, did you find it?"
Yang Yiyi shook her head, turned the computer slightly, and pointed to the word document on it: "The specific parameters of 'Flash No. 2' are too difficult to find. I doubt that it is possible to find them at all. There are only these relevant experimental data found in the literature, and some theoretical data based on the simulation of 'Flash No. 2'."
Chen Zhou glanced at the content compiled by Yang Yiyi and nodded slightly: "That's enough, this data should be enough."
Yang Yiyi looked at him in confusion: "What do you mean almost done?"
Chen Zhou sent the word document he had compiled to Yang Yiyi, and said, "It's almost enough to reverse-calculate the parameters of 'Flash No. 2'."
"Ah?" Yang Yiyi was a little surprised. "Are you planning to reverse-calculate the parameters of the equipment?"
She was really surprised by Chen Zhou's idea. You know, errors in experimental data will always exist. According to the theoretical formula, it is very difficult to reversely infer the parameters of the equipment through experimental data.
"How do you know it won't work if you don't try it?" Chen Zhou smiled at Yang Yiyi, then pointed at the flashing QQ on Yang Yiyi's computer and said softly, "I've sent you some experimental data. Thank you for your hard work. Please integrate the information we collected by experimental type."
Yang Yiyi looked at the confident smile on Chen Zhou's face. She understood something and said with a smile, "You are probably the only one in the whole laboratory who would do this."
Chen Zhou reached out and rubbed Yang Yiyi's head: "Don't you still have me here?"
Yang Yiyi smiled slightly. She had already downloaded the information sent by Chen Zhou, and at the same time sent a copy of the information she had sorted out to Chen Zhou.
"Happy, do you think it would give them a big scare if we calculated the ideal experimental parameters?"
"Of course! If it succeeds at once, it will save at least half the time compared to before!"
"Then let's shock their eyes!"
After Yang Yiyi finished speaking, she began to carefully organize the experimental data.
Chen Zhou took a look at the girl and thought that it would be great to have a girlfriend who could keep up with him and was willing to believe in him!
If he were to do these things alone, he might choose to study mathematical conjectures because the work is too huge...
Of course, the reason why Chen Zhou did this was because he was confident that he could peek into the secrets of "Flash 2" from the data .
This was probably also a great improvement in his mathematical ability, which gave him special confidence in data processing.
While receiving the documents, Chen Zhou took out his mobile phone and planned to check the message from Wu Xiping.
He was so immersed in searching for literature that he almost forgot about it.
On his mobile phone, Wu Xiping replied to three messages, one within 10 minutes and the other within more than two hours...
[I have something to ask you. Are you busy now? If not, come to my office.]
【Please reply if received! 】
【Remember to reply to me if you see this. 】
After reading these three messages, Chen Zhou looked at the information sent by Yang Yiyi again, thought about it, and prepared to reply to Wu Xiping.
[Professor Wu, I'm a little busy now. I'll call you back later.]
After editing, Chen Zhou took a look at it, changed "a little bit" to "very much", and "a while" to "after I'm done", and then clicked send.
Over there, Wu Xiping's cell phone rang and he immediately looked at it.
After reading Chen Zhou's reply, he put down his phone again and said to Shen Jing in front of him: "Chen Zhou will be here for a while, you can take a look at the information first."
Shen Jing nodded: "Okay, Professor."
However, Shen Jing never expected that the "a little while" Wu Xiping mentioned would actually be 9 am the next day...
Here, Chen Zhou put away his phone again and started to get into the state.
"Yiyi, I will start with the numerical simulation and experimental data of the anode rod pinch diode, and you organize the data of other diodes." Chen Zhou said softly.
"I've already put that aside, knowing you would start with it." Yang Yiyi replied with a smile.
Hearing this, Chen Zhou smiled knowingly. What is a good partner, what is tacit understanding, what is a girlfriend, this is it!
There is no need for me to say anything more, Yang Yiyi understands everything!
Yang Yiyi was organizing the information, while Chen Zhou was struggling between paper and pen.
Why is reverse deduction difficult?
Because the physical problems involved in this type of diode, high-current self-pinch diode, are quite complex, such as the extremely strong space charge effect, the pinch effect generated by the self-magnetic field, the emittance growth effect, the tail field effect, the energy dispersion effect, etc., none of which is easy to deal with.
Tracing the cause from the effect is actually an extremely important research method in mathematical research.
Just like the proof of a mathematical conjecture, it can also be said to be tracing the cause from the effect.
This is one of the reasons why reverse deduction is so difficult.
Of course, since Chen Zhou chose the reverse method, he would not give up halfway.
After all, no matter how difficult it is to reverse the process, it is not as difficult as proving the hail conjecture, right?
