Volume 1: Student Life Chapter 254 The Value of Trial and Error
After lunch, Chen Zhou and Zhang Yifan took a short rest to digest the food and relax.
They still have a long work day ahead of them in the afternoon.
Chen Zhou took advantage of this time to take out the collection of wrong questions from his backpack.
Just as expected, the collection of wrong questions can be summed up in one word: a lot!
All the literature data that Chen Zhou had read were recorded on it.
Before finding a suitable preparation process, as Chen Zhou read more and more literature, the content recorded in the collection of wrong questions would also increase.
But if Chen Zhou finds a suitable direction, the collection of wrong questions will become a place for trial and error.
Moreover, in this direction, with the improvement of the preparation process, the content originally recorded in the wrong question collection will gradually disappear.
If and only if Chen Zhou perfectly solves the difficult problem of preparation technology, all the contents in the wrong question collection will disappear.
However, Chen Zhou did not have high expectations for this. How easy is it to have a perfect preparation process?
He only hopes to find a relatively complete preparation process to solve the current problem.
After all, Chen Zhou still understands the principle of eating one bite at a time.
After analyzing the data in the collection of wrong questions, Chen Zhou closed the collection and closed his eyes.
Ten minutes later, he opened his eyes and sat in front of the computer.
Research continues.
"Higher microwave power density can enhance the decomposition and ionization of the reaction gas, increase the concentration and activity of individual reaction groups, promote growth, and improve growth efficiency..."
"In addition to the influence of these reaction gas parameters, there is also the influence of the MPCVD device itself. How should the shape of the substrate holder be selected to reduce power loss and improve diamond production efficiency?"
Chen Zhou looked at the sorted information in front of him, and these questions kept flashing through his mind.
He habitually took a pen and tapped it on the draft paper, and when he had an idea, he would write it down.
Wait until you have finished reading all the information before organizing these thoughts.
"According to previous experimental data, the MPCVD method can produce diamond films of tens of nanometers as well as millimeter-scale diamond thick films."
"However, this requires a larger diamond substrate, and in subsequent doping experiments, if heteroepitaxial growth is difficult, it will also make it difficult to prepare large-sized, high-quality diamond single crystals."
"All in all, it is still difficult to choose the appropriate parameters for preparing diamonds."
After Chen Zhou re-sorted out the literature materials compiled by Zhang Yifan and Shen Jing, he began to sort out the content he had written on the draft paper.
This thing can be said to be the essence extracted.
While sorting out the issues, Chen Zhou was thinking about corresponding solutions.
"The volume fraction of CH4, working pressure, microwave power, substrate temperature, etc. can only confirm the approximate range, and it is impossible to accurately determine the experimental parameters..."
Chen Zhou wrote page after page of draft paper, all filled with trial and error.
After a long time, he put down his pen, opened the collection of wrong questions, and looked through it carefully.
This is where the value of trial and error in the wrong question collection lies.
For ordinary people, the cost of trial and error is repeated experiments.
Based on the experimental feedback data, gradually improve the experimental parameters and move closer to reasonable experimental goals step by step.
Among these, the cost of trial and error, whether it is time, energy, money, or equipment, is a huge consumption.
But for Chen Zhou, the collection of wrong questions saves the experimental steps and also saves a lot of substantial trial and error costs.
This is actually what Pan Shiyan has always been confused about.
It was getting dark outside.
Chen Zhou and Zhang Yifan only came to their senses when Peng Fei and Shen Jing appeared at the door and knocked.
Rubbing his temple, Chen Zhou stood up and opened the door.
Seeing the two people at the door, Chen Zhou smiled and asked, "How was your day?"
Peng Fei replied: "The co-doping experiment was completed as planned. I have to go back to the laboratory to sort out the experimental data."
"Working overtime at the institute tonight?" Chen Zhou looked at Peng Fei in surprise. Is he planning to sort out the 10th set of data tonight?
Peng Fei smiled and said, "You've asked for help and stayed up late to do research. We can't fall behind, right?"
Chen Zhou smiled embarrassedly. In fact, he wanted to say that there was no rush for the 10th set of data.
Because, even if he sorted it out, he didn't have time to study it in the next two days.
At least we have to wait until he comes up with a satisfactory diamond film preparation process and have the 43rd Institute verify it through experimental equipment.
Only then will he start the doping experiment.
"By the way, will you continue to work in the hotel tomorrow?" Peng Fei asked again, remembering that the document materials Chen Zhou assigned to him had not been sorted out yet.
Chen Zhou thought for a moment and said, "We should still be in the hotel tomorrow. Well, if you guys have sorted out the 10th set of data, I will go to the 43rd Institute again to integrate all the data."
"Okay, then I understand. I'll rush back to the office now." After saying this, Peng Fei left the hotel.
Chen Zhou looked at Peng Fei's back as he left, wanting to say something but stopping himself. He really didn't know what Peng Fei understood.
Shen Jing, who was standing by, finally said with a tired look on his face, "Chen Zhou, you're not really going to let me go to the No. 43 Institute alone tomorrow, are you?"
Chen Zhou asked back: "Have you processed all the data for today?"
Shen Jing nodded: "After all the hassles, we finally got it done."
Chen Zhou glanced at Shen Jing and said solemnly, "That's it. Senior, there is only one set of data left tomorrow, it will be quick. Once this last set of data is done and a little integration is done, it will also be quick."
"Uh..." Shen Jing said hesitantly, "This is quite a workload."
Chen Zhou: "Senior, I'm optimistic about you."
Shen Jing: “…”
After a while, Shen Jing said softly: "I haven't finished sorting out the documents you sent."
Chen Zhou smiled and did not answer the question. He turned to look at Zhang Yifan and said, "Let's go, Yifan, let's go eat."
Zhang Yifan raised his head and looked at Chen Zhou in confusion after hearing that. The topics these two people were jumping around so much?
Isn’t Shen Jing complaining that he has too much work and is overwhelmed?
How come we are talking about eating?
Chen Zhou seemed to see what Zhang Yifan was thinking, and chuckled and said, "After you're full, let's continue the second half!"
Zhang Yifan: “…”
Shen Jing: “…”
While eating, Chen Zhou received a document sent by Yang Yiyi.
Yang Yiyi had finished half of her work, so she sent over half of the information she had sorted out first.
Chen Zhou opened it and took a look, then made a video call to Yang Yiyi.
Among this group of six, perhaps only Yang Yiyi can keep up with his thoughts and ideas.
It can also provide timely and accurate feedback on useful literature information.
However, Chen Zhou is not in a hurry after this adjustment.
It would be much better if there is an opportunity to conduct joint research on a topic in the future.
