Seeing this situation, everyone felt a little helpless, and it was this gap that affected the results of the experiment.

If there was no gap, the experiment would have been successful, but now it seems that a certain amount of material disappeared in the process of repair, so a small gap was left.

This experiment can be said to be a success or a failure, the success is due to the completion of the repair task, and the failure is due to the small gap left behind, which is the flaw of the experiment.

But now at least there is hope, unlike before, Shang Yiyun believes that as long as experimental research continues, it will not take long to create a relatively perfect repairable metal material.

Today's first experiment can achieve this effect, Shang Yiyun is also quite satisfied, as long as in the next time, find out the problem, let the experiment go further, it is a victory.

In the following time, everyone did not rush to do the experiment, but thought about why there were gaps in the metal materials that could be repaired, as long as the problem was understood, the success of the experiment was a matter of time.

The members of the team got together in twos and threes to discuss this issue, while Shang Yiyun discussed it with two professors, Xu and Wang.

In this way, it lasted for half an hour, and the cause of the cracks in the metal material could be repaired, and a preliminary idea was made, and the next step was to verify the idea.

The experiment restarted, this experiment, Shang Yiyun was going to do it himself, the experimental steps were carried out step by step, and after a period of time, he looked at the repairable metal materials on the test bench, and a smile appeared on his face.

Although there are still gaps in the material, it is significantly smaller than just now, which is a big improvement compared to before.

"Shang Yiyun, seeing you smiling so happily, could it be that this experiment was successful. ”

It was at this time that he suddenly heard Professor Xu's voice.

"It's still a little bit close to success, but it's a big improvement compared to the previous time, and I believe that success is just around the corner. ”

When he said this, Shang Yiyun's tone was full of confidence, and he was very sure about the next experiment.

When Professor Xu heard that Shang Yiyun was so confident, his whole person became relaxed unconsciously, and even Professor Xu himself did not know about this change.

After repeated experiments, the repairable material on the bench is close to perfect, but there is still a flaw, that is, the material has left a small hole the size of a needle tip, which will not be found if you are not careful.

But this is really a flaw, and I have experimented several times in succession, and each time it has been this result.

But in real life, those metal pipes that transport things can't have a single flaw at all, and if this small hole the size of a pin's eye can't be eliminated, it means that the experiment has not been successful.

Faced with this situation, Shang Yiyun fell into deep thought, thinking about the reasons for this result.

Suddenly, he seemed to think of something.

When these metal materials were destroyed before, they reacted with some special elements, and some things volatilized into the air, which led to this result.

The more he thought about this speculation, the more he thought it was possible, so he used an instrument to carefully probe the substance on the surface of this metal.

After a while, he finally found something, around the small hole the size of a needle's eye, there was a special element, and he didn't know what it was for a while.

Once you've found the problem, the next step is to solve it, so the most important thing is to figure out what element it is, and then you can figure out how to solve it.

This kind of thing, Shang Yiyun handed over to the two professors, Xu and Wang, believing that with the ability of the two, as long as there are no accidents, they can definitely let him know the information of this unknown element.

After hearing Shang Yiyun's words, the two professors used instruments to detect what elements the unknown substance was composed of, and it took a few minutes to analyze the elements.

Now the experiment can no longer be done, and we can only wait until the two professors are engaged in what the elements of architecture are, otherwise the final result will be no different from the previous experiments.

Since it was impossible to conduct experiments now, and he looked at the time just now, it was already lunch time, and it was useless for everyone to stay here at this time.

So he asked everyone to leave the lab to solve the lunch problem, learn about this element in the afternoon, and then discuss the follow-up experiment plan together.

When leaving, Shang Yiyun invited the two professors, Xu and Wang, to have lunch together and chatted by the way.

Hearing Shang Yiyun's proposal, the two professors thought for a while and agreed, but before leaving, they called their families and explained the situation.

After everything was ready, the three of them came to a restaurant outside the school, ordered four dishes and one soup, and Shang Yiyun bought a bottle of liquor from outside and prepared to have a drink.

Before coming, he had consulted the two professors, as a northerner, he usually drank some wine on this occasion, but the three of them would not drink too much, wine is a bridge to add to the relationship at the dinner table, but it is not suitable to drink too much.

After the meal was ready, the three of them chatted while drinking, from professional knowledge to daily life, Shang Yiyun could feel that the relationship with the two professors had made great progress, before, professors were professors, and students were students.

But now that the topic is open, the three seem to have a relationship similar to that of a year-old friend.

The professor is still a professor, and the student is still a student, but it is conceivable that in the future, when he faces the two professors, he will definitely be more casual.

This lunch, which took half an hour, was spent chatting most of the time, and the amount of food for the two professors was very small, and most of the food on the table went into Shang Yiyun's stomach.

After lunch, Shang Yiyun parted ways with the two professors, both professors went home, and he went to the library.

When he has a problem, he likes to think in the library, as if the library can give him inspiration.

Looking at the element analysis sheet in his hand, Shang Yiyun fell into deep thought, most of these elements were some common elements, but there were also some relatively rare elements.

Repairable metal materials, in order to repair the process, without some chemical reactions, can be done under some specific conditions, but if you want to make this repairable metal material apply in a large area, you must find a way to prevent chemical reactions at room temperature.

It was not an easy task to find this method, and he had no clue right now, and his mind was in chaos.

For a while, he couldn't think of any way, he was going to look for a book in the library to read and relax.
