It took twenty minutes to complete the repair task, Shang Yiyun was not satisfied, he wanted to compress the time a little more, and strive to complete the repair within five minutes.

There is still a long way to go to get to the results he envisioned, but it is not hopeless, and he believes that if he continues to research, he will definitely be able to meet his expectations.

Moreover, the research topics are mainly the practical application of repairable materials.

The most anticipated practical application is on the screen of a smartphone.

In the past, after the mobile phone screen was broken, it was necessary to replace it with a new one, but if the mobile phone screen can be made with self-healing materials, it can also be repaired by itself after it is broken, which reduces the consumption of materials.

Of course, the application of self-healing materials to mobile phone screens involves some technical difficulties, so now we can only carry out research on other practical applications.

The first experiment had already failed in Shang Yiyun's heart, and after summing up the experience, the next experiment began.

"Wang Fei, pay close attention to the data of the experiment and make a good record. ”

"He Miaomiao, strictly follow the steps to carry out the experiment. ”

......

Let some students participate in the experiment, and Shang Yiyun is responsible for observing and regulating the whole.

After everything was ready, as Shang Yiyun said the word start, the experiment began again, and each student stuck to his post, and the experiment was in full swing.

For this experiment, Shang Yiyun didn't think that it could be done in one step, and directly compressed the repair time to less than five minutes.

However, being able to reduce the repair time by another minute is a huge step forward.

The material used in this experiment is a piece of repairable glass, which has been successfully tested before, but in that experiment, the repair took about half an hour to complete.

Their previous experiment, which took a total of 20 minutes from the beginning of the restoration to the completion of the restoration, was mainly due to the difference in materials.

The repairable glass material used by the team of Shangyiyun can be said to be a newly developed repairable material, so it is higher in terms of performance.

After a period of time, the experiment ended, and it took 19 minutes and 30 seconds from the beginning of the material repair to the completion of the repair, which is half a minute longer than before.

This is already an improvement, and although it is still far from what he wanted, at least it has improved.

Next, Shang Yiyun commanded everyone to do a few more experiments to compress the repair time to fifteen minutes, but after reaching this level, no matter how much the experiment was, they could not continue to reduce the repair time.

Faced with this situation, Shang Yiyun also knew that he couldn't be in a hurry, so today's experiment ended here.

Next, after cleaning up all the instruments and equipment, and experimental materials, let everyone think about it after they go back, and strive to continue to make progress next time.

As for him, he chatted with Professor Xu and Professor Wang for a while, and after summarizing today's experiments, he left the laboratory.

Today's experiments, on the whole, are relatively successful, although they do not meet his requirements, but he also gets along, and the emergence of research results is not achieved overnight, but through the failure of a large number of experiments, it is possible to exchange for a success.

Since today is Sunday, after doing the experiment in the morning, he will be fine in the afternoon, so he is going to go to Huaguo Normal University, because there are more things in the past two days, so he did not accompany Chen Feiyun.

The other party can also understand, so he didn't ask to accompany her in the past two days, and Shang Yiyun was also a little guilty about this situation.

However, he was naturally very happy that the other party could understand him, so now that he had free time, he was ready to accompany the other party.

He didn't tell the other party in advance, but was ready to surprise the other party.

On Sunday afternoons, he knew where the other party usually went, and under the influence of Shang Yiyun, Chen Feiyun liked to go to the library to read books on weekends.

She doesn't have Shang Yiyun's talent, but she has also gained a lot from reading books in the library for a long time.

As long as the other party has nothing else to do, the eight achievements are in the library, so he is going to go directly to the library to find the other party.

When he came to the library of Huaguo Normal University, he found that how to enter the library had become a problem.

To enter the library, he needed a campus card, and he didn't have one.

But this is only a small problem, he stopped a person who was about to enter the library, explained the situation to the other party, and just borrowed the other party's campus card to enter the library.

After entering, he went directly to the reading room where Chen Feiyun often went, preparing to see if there was anyone in this reading room.

When he entered the reading room, he swept around and finally found the place where Chen Feiyun was.

Shang Yiyun was ready to give Chen Feiyun a surprise, so naturally he would not alarm the other party, so he cautiously came to the other party's side, found a stool and sat down, supported his cheek with one hand, and quietly watched the other party read.

At this moment, Chen Feiyun's eyes were on the books in front of her, and she didn't notice Shang Yiyun's arrival.

After a period of time, perhaps because of Shang Yiyun's fiery gaze for a long time, Chen Feiyun seemed to feel something, so she raised her head and made a look at Shang Yiyun.

"Yi Yun, when did you come, don't tell me in advance. ”

Although the content of the painting seems to be blame, the tone is full of excitement.

Shang Yiyun told her before that she had no spare time because of the experiment, and although she could understand, her heart was still full of loss.

Now, the other party came to her side unconsciously, and her heart was full of surprise.

"I did some experiments in the morning, and there were some results, but research is not something that happens overnight, so this afternoon is a free time, so I came here as soon as possible. ”

Hearing Shang Yiyun's words, Chen Feiyun's sense of loss disappeared completely, and her mood became beautiful.

Shang Yiyun came here, and Chen Feiyun didn't have the heart to continue reading, and the two of them were going to go to the small shop near the school.

It doesn't matter if you buy something or not, the main thing is how the two feel together.

After Chen Feiyun returned the books to the library, she pulled Shang Yiyun out of the library.

Seeing the other party's happy face, Shang Yiyun was also very happy in his heart, what he was most worried about was that the relationship between the two would be estranged when they met once a week, but now it seems that he is too worried.

Shang Yiyun and Chen Feiyun walked on the campus road, which aroused the envy of many people, Huaguo Normal University is generally prosperous and yang, Chen Feiyun's campus is mostly art students and normal students, so the ratio of men and women is even more exaggerated.

Therefore, if you want to fall in love, you have to import it from other schools.
