God-level Xueba system

"Professor Wang, Professor Yang!"

Seeing the two professors rushing towards him, Sun Jinghua hurriedly raised his hand to say hello with a smile.

Yan Xin didn't move at all!
Sun Jinghua couldn't help sneering.

this kid!
Why is there no manners at all?
Yan Xin looked up, what a coincidence!

This Professor Wang is exactly Wang Gang, and the one next to him is also a female professor who was in the conference room just now.

When Sun Jinghua was thinking about how the two professors would blame Yan Xin, that Wang just raised his eyebrows at Yan Xin: "Oh! Isn't this Professor Yan? He was slaughtered by Lao Qiu just now! Haha Ha ha!"

Professor Yang also smiled and nodded to Yan Xin first, but ignored Sun Jinghua at all.

Yan Xin couldn't help but feel ashamed.

Unexpectedly, this Wang just now is so old, and he is as noisy as Qiu Jianxun!
Sun Jinghua was dumbfounded on the spot!

What's up with this kid?
Why did the two professors nod and bow when they saw him?

Isn't he just a teenager!

"Hahaha, don't dare! I don't know why Professor Wang and Professor Yang are in such a hurry?" Yan Xin asked with a smile.

"Oh! That's it, Yan Xin, no, Professor Yan! There are some problems with our ion coating machine, and we are going to ask the engineer at the guard's phone!" Professor Yang replied.

what!
Sun Jinghua seriously suspected that something was wrong with his ears!

Professor Yang was called Professor Yan Xin just now?

I was just mocking him for not being as educated as myself!
In less than a minute, how did Yan Xin become a professor?

and many more!

There is no time to think about these things now!
Professor Yang said that there was a problem with the ion coating machine, so the samples he had polished before were all useless!
If the machine cannot be repaired in time, the samples that I just polished and polished cannot be put into the cavity of the ion coating machine, and they will all be oxidized in the outside world!

The efforts of the past few days have all been in vain!

"Professor Wang, what's wrong with the ion coating machine? My samples are all ready!" Sun Jinghua said anxiously.

"It seems to be a problem with the cavity! I don't know the specific situation! I can only call and ask the engineer to come over!"

Done!

It usually takes an engineer two days at the fastest to arrive at the Dragon Academy of Sciences, and by then his samples will have been scrapped long ago!
How to do!
"Don't panic! Professor Wang, Professor Yang, why don't you take me to have a look? I really understand the structure of the ion coating machine before, maybe I can help you!" Yan Xin said with a smile.

"Alright!"

Professor Yang himself is in charge of the instrument, and if something goes wrong, he may have to pay for it himself.

If Yan Xin can really fix it, that would be great!

At this time, Sun Jinghua didn't have the heart to run on Yan Xin, and took the lead in walking in the front.

The ion coating machine is placed in area b of the laboratory, which Yan Xin saw before when he came in for a visit.

This machine is mainly used to coat various ground and polished substrates. There are two main methods: one is multi-arc ion plating technology, and the other is magnetron sputtering technology.

When the four of Yan Xin arrived, although the ion coating machine was running, the sound was different from when Yan Xin came that day, and there was always a booming sound.

What's going on here?
Sun Jinghua stood aside with a dull expression.

He just knows how to do experiments, but he doesn't know how to repair machines at all!

After all, there is only one set of experimental procedures, so you can change the soup without changing the medicine!

If the machine doesn't work today, then all the samples he's been working on for several days will be wasted!

Yan Xin walked around the machine and found that there was nothing wrong with it. Professor Yang and Professor Wang also adjusted the parameters inside the machine, and there was nothing wrong with it.

"Professor Yang, do you need to turn on other devices when this machine is running normally?" Yan Xin asked.

Professor Yang nodded: "Yes, you still need to turn on the press, cooling water machine, protective gas tank, nitrogen tank, and chronograph!"

Looking at the machines in the house, Yan Xin couldn't help but fell into deep thought.

I have seen this type of ion coating machine in papers before, but I have never encountered the booming sound of the cavity.

Professor Yang and Professor Wang also adjusted the working parameters of the machine and found that there is no problem with the main body, so the problem must be with these auxiliary devices!

Yan Xin felt the temperature of the cavity and found that it was abnormally hot.

"Professor Yang, when the ion coating machine is working, is the temperature of the cavity also so high?"

"This can be adjusted by the parameters! But I usually don't add temperature when coating! This will damage the target!" Professor Yang replied.

"Yes! If nothing else, it's a problem with the cooling water machine! The reason for the booming noise is that there is a blockage or break somewhere inside, which prevents the condensed water from cooling the cavity smoothly! We just need to work hard Just look for the cooling water pipe!"

Yan Xin looked back at Sun Jinghua who was standing dryly: "You, go find the main valve of the cooling water pipe, and close it!"

After Sun Jinghua heard what Yan Xin said, he froze in place and didn't move at all.

Why do you order me?

Do you really think you can fix this machine?

"If you want your sample to be discarded! I can ignore it!" Yan Xin stood up and walked out of the laboratory.

Sun Jinghua glanced at Wang Gang, who just didn't bother to talk to him.

He is naturally on Yan Xin's side.

People kindly come to help you, why the hell are you just standing there and watching?

Sun Jinghua walked to the control box with a face of reluctance, and carefully closed the main cooling water valve.

Can this kid really fix it?

If he can fix it, I will just bow and nod and apologize to him!

Can you really pretend to be aggressive, thinking that after solving the Riemann hypothesis in the field of mathematics, you can get involved in the field of materials?
Yan Xin searched along the cooling water pipes for a long time, and finally found the root of the problem at the water inlet of the multi-arc ion plating!
It's really a problem with the cooling water!
When ion plating is performed in the cavity, the protective gas argon will bombard the target, even if no temperature is added, a high temperature of about [-] degrees will be generated.

And the plastic pipe of the cooling water must be that the engineer accidentally got close to the inner wall of the cavity when connecting, causing the plastic pipe to melt into a jelly, preventing the cooling water from entering the cavity.

"Professor Yang, the root of the problem is here!" Yan Xin unplugged the water outlet pipe from the water inlet of the multi-arc ion plating.

"Oh! It's all melted! I said why the cavity is so hot! It's because the cooling water didn't reach the inside of the cavity in time!"

Professor Yang was stunned!
Thanks to Yan Xin who discovered it in time, otherwise it would be easy to cause a fire after a long time!
"Sun Jinghua, after finishing the experiment, you must check the machine carefully! Otherwise, the 80 million equipment will be ruined! Thanks to Yan Xin today, he is really a genius boy! The problem was found in a few minutes where!"

Professor Yang was full of praise for Yan Xin.

If it wasn't for Yan Xin, the higher-ups would really blame me for being sloppy!

"Then what do you think is the best way to cultivate?" Professor Yang asked.

"This is simple! The material of this pipe is different from other plastic pipes! I think that since it is close to the heat source, it should be replaced with a plastic with a higher melting point! This one was called U-PVC before, which is hard polyvinyl chloride. Its melting point is about It is not very high at 150~200 degrees Celsius! I suggest you use PET material, which is polyethylene terephthalate. Its melting point is relatively high, around 300 degrees Celsius, which is enough! As long as it is installed , away from the cavity, there will be no problem!"

Wang Gang couldn't help giving Yan Xin a thumbs up.

But Sun Jinghua was in a daze.

I have no idea what Yan Xin is talking about.

This is all the chemical knowledge of a graduate student. How could he understand it as a metal material!
"Sun Jinghua, go to the hardware store outside to buy it! Just follow what Yan Xin said and buy polyethylene terephthalate cooling water pipes! Don't buy the wrong one! You can do this kind of small job in a while. Put it on, and it won't affect today's use."

After Professor Yang finished speaking, he held Yan Xin's hand with a smile: "Yan Xin, no, Professor Yan really lives up to his reputation! Admiration! He really helped me a lot!"

"Haha, Professor Yang has won the award! I have read related papers before, and besides, everyone is engaged in scientific research, so it's okay!"

Yan Xin scratched her head.

Yan Xin felt a little uncomfortable being called Professor Yan while being held by someone ten years older than herself.

"Okay, since the problem is solved, Professor Yang and I will go to work first! Sun Jinghua, don't forget to buy and replace it! Yan Xin, go to work!" Wang just finished talking and left with Professor Yang.

"Why, do you have any questions?" Yan Xin looked back at Sun Jinghua.

"I'm sorry! Thank you so much today! If it weren't for you, all my samples would have been scrapped! I apologize for my attitude towards you before!"

Sun Jinghua bowed deeply to Yan Xin, and then didn't look up.

Yan Xin came to the front and said sharply: "It's okay! But I still hope you remember! Whether it's studying abroad or seeking knowledge in the mainland, our ultimate goal is to serve the country! Don't think that you are so awesome when you come back from overseas! Let's Long Xia has a lot of talents! People are humble and self-knowledge, not pretending to look down on others! Also, knowledge is not in books, but in the mind, but it is useless to learn it, you have to learn to apply it! I will work hard on you today Replace this cooling water pipe!"

"Okay! Yan Xin, no, Professor Yan, then you should do your work first!"

Sun Jinghua didn't have the arrogant attitude just now, Yan Xin helped him a lot by repairing the machine!
There is no need to redo the samples of these days!

Sun Jinghua quickly nodded and said yes, Yan Xin patted Sun Jinghua on the shoulder and walked out of the laboratory.
