Master and disciple can eat a meal that is calm and dull.

Teacher Ye seems to have always been worried. Senior Brother Cai didn't say much, Bai Gangpeng and Yu Kehui were very dull; Long Jianhua didn't know what they were thinking, and he was embarrassed to liven up the atmosphere.

It is very tiring to eat with research-oriented intellectuals, especially when Teacher Ye doesn't allow him to drink.

When the dinner was about to end, Teacher Ye suddenly said, "Long Jianhua, can you prepare an optical fiber core?"

Cai Kailan looked up at Teacher Ye in surprise, then looked at Long Jianhua again.

"Teacher, isn't someone preparing it? Will this waste manpower and material resources?"

"The current research methods are just copying those documents. Long Jianhua is a newly recruited graduate student. He has his own ideas. It is good to experiment in another way. It is not a waste or not..."

Long Jianhua was eating mutton and almost choked and coughed several times.

The teacher is too conversational.

"What, scared?"

Teacher Ye smiled.

Long Jianhua shook his head quickly, "I'm willing to give it a try."

As a reborn person, he is here to intercept the slap; if there is such a good thing, how can you not intercept the slap?

Teacher Ye asked with great interest, "Oh, how are you going to do it? How many people need to cooperate?"

"Teacher, this is still a bit far away. I need to prepare the test plan, find raw materials and make equipment."

As an undergraduate graduate of organic synthetic materials, he is very good at doing experiments, the key is the plan, etc.

Teacher Ye nodded with a smile, "Yes, I didn't ask for someone from me first. Bai Gangpeng and Yu Kehui both have their own research projects, and they can't cooperate with you; if you need it, you can only find some undergraduates with strong hands-on skills for you."

Bai Gangpeng and Yu Kehui were shocked.

Isn’t there a professor who is leading a team to study there? How could the teacher give him such a difficult task?

Is this special junior brother so powerful?

He didn't seem to be nervous at all. Don't you know the difficulty?

Cai Kailan asked with interest, "Junior Brother Long, have you ever been exposed to knowledge about fiber optics? What are the factors that affect fiber optics performance?"

Long Jianhua blurted out, "Material composition, structure, refractive index and manufacturing process."

Cai Kailan further asked, "Where is the craft?"

"OVD, VAD, MCVD, PCVD are all based on chemical vapor deposition methods..."

Cai Kailan, "How many journal materials have you read?"

Long Jianhua scratched his head, "The teacher gave us such a question, which actually requires optical fiber, so I paid attention to the information in this regard."

Teacher Ye looked at him with admiration.

Bai Gangpeng and Yu Kehui were still confused between A and C.

Yu Kehui looked at him blankly.

This junior brother Long seems to know a lot about fiber optics, why don’t I know these things?

I hope you only know the name but not the content, otherwise it will embarrass me...

Cai Kailan sighed slightly, "You do have an understanding of this aspect. I hope you can make one quickly. Some people in China are preparing it and have entered the stage of success. I hope you can make it in one shot, or prepare it first, or perform better than theirs."

Teacher Ye clapped his face, "Long Jianhua, hurry up and make the plan. There is still one in my laboratory that can be used, so you can hand it over to you; as for the funds, I don't have much to provide, so I will provide one thousand yuan as the start-up capital first."

Yu Kehui is infinitely envious.

What a big project this is?

How much should be the start-up capital of one thousand?

When the teacher asked me to study the spectrometer, the start-up capital was only 300 yuan.

Long Jianhua smiled bitterly.

One thousand dollars.

There are so many medicines, so many equipment, and there are fewer soups.

This is the current scientific research environment, this is the greatness of this generation of scientific researchers...

Third, he handed over the plan to Teacher Ye for review, and Teacher Ye passed it without changing a word.

As a participant in scientific research in this era, Long Jianhua tried his best to do everything possible.

Chlorine gas, borrow two cans from the Chemical Research Institute.

He had a leading advantage, and had conducted joint research with his uncle in a machining factory, and some special materials could be used in his name to do some experiments there.

For simple equipment, please ask aunt Zhao Hongying to arrange processing.

Teacher Ye is a professor and is carrying out major projects, chemical reagents, and you can get them from the school, or borrow or buy them from the Chemical Research Institute.

Borrow it? It's just a quotation, and I'll return it when I think about it.

Kong Yiji has been through: Can studying be considered stealing?

So, can you borrow national affairs?

Pour this bowl into another bowl.

These relationships are not used... they are useless.

However, you still have to invite someone to dinner. The smoke that should be dispersed must be dispersed. You cannot treat those who are willing to help.

All I paid... were my own money.

Bottles of reagents were moved into the laboratory, and equipment was moved into the laboratory...

On June 23, the last self-made equipment was carried into the laboratory by Long Jianhua.

At 3:00 p.m. on June 24, half a bottle of silicon tetrachloride was made.

Bai Gangpeng and Yu Kehui, who were doing experiments in the laboratory next to them, put down their work and followed them in.

Bai Gangpeng took a hand in hand to remove the equipment, "Junior Brother Long, how much money have you spent on so many equipment?"

Long Jianhua smiled, "Not half of the 1,000 yuan is used yet."...

No high-purity raw materials? Made yourself!

Heat the silicon powder to 238 degrees, pass it into hydrogen chloride gas, and distillate it...

The first bottle of product was light yellow in color, and Long Jianhua frowned.

Not purity...

I haven't done an experiment in person for a long time. I feel that some of the skills have been loose and I still don't have enough control over the key points inside. Fortunately, my brain reacts very quickly.

Senior Brother Bai, "This is much lighter than the silicon tetrachloride I saw last time, and it is much purer. Is Junior Brother Long still not satisfied? Isn't there a purification process later? Some impurities can be removed at that step."

Seeing Long Jianhua staring at him, I felt embarrassed, "I happened to hear the teacher discussing with others, and I listened a few words."

Long Jianhua shook his head.

This is manual operation, and the environment does not meet the requirements. There will be obvious pollution at every step; if you can do it, why not do it?

Yu Kehui laughed and said, "Junior Brother Long, although you haven't spent half of the money yet, the experiment has just begun. There are still many places to spend money in the future, and we have to save money. For us graduate students, one thousand yuan is already a lot."

Long Jianhua smiled, "The medicine is very cheap. It's only more than ten yuan to buy ten bottles, but this will have a great impact on my future product quality...the decay of light summer, so we must make every step more perfect."

Chemical experiments are not large-scale production. Equipment has many interference factors, which can easily cause unstable yield and quality; therefore, even if the laboratory has successfully verified the technology and products, the company will have to go through a long time to explore after buying them.

Yu Kehui shook his head, "The funding is very tight. You can't ask for too high a requirement, it's a waste."

Teacher Ye walked in and saw the silicon tetrachloride in Long Jianhua's hand. He asked in surprise, "Is this what you did?"

Seeing Long Jianhua nodding, he smiled and said, "No, you can do it more pure."

It can also be made pure...
