It can be said that the meal of the five teachers and disciples was very calm and dull.
Mr. Ye seems to have something on his mind. Elder martial brother Cai doesn''t have much to say. Bai gangpeng and Yu Kehui are very boring; Long Jianhua didn''t know what they were thinking and was embarrassed to liven up the atmosphere.
Eating with research intellectuals is very tiring, especially when Mr. Ye doesn''t allow drinking.
At the end of the meal, teacher Ye suddenly said, "long Jianhua, can you prepare an optical fiber core?"
Cai Kailan looked up at teacher ye in surprise and turned to long Jianhua.
"Teacher, isn''t someone preparing it? Will this waste manpower and material resources? "
"The current research method is only the reproduction of those documents. Long Jianhua is a newly recruited graduate student. He has his own ideas. It''s good to experiment in another way. There''s no waste... "
Long Jianhua was eating mutton. He almost choked and coughed several times.
The teacher is so talkative.
"Why, scared?"
Teacher Ye smiled.
Long Jianhua quickly shook his head, "I''m willing to try."
As a reborn man, he came to cut his beard; With such a good thing, how can we not cut off this beard?
Mr. Ye asked with great interest, "Oh, how are you going to start? How many people are needed? "
"Teacher, this is a little far away. I want to prepare the test plan and look for raw materials and manufacturing equipment. "
As a graduate of organic synthetic materials, doing experiments is very good. The key is the scheme, etc.
Mr. Ye smiled and nodded, "yes, I didn''t ask for someone first. Bai gangpeng and Yu Kehui have their own research projects and can''t cooperate with you; If you need it, you can only find some undergraduates with strong practical ability to give it to you. "
Bai gangpeng and Yu Kehui were stunned.
Optical fiber, isn''t there a professor with a team studying there? How did the teacher give him such a difficult task?
Is this special younger martial brother so powerful?
He doesn''t seem a little nervous. Don''t you know the difficulty?
Cai Kailan asked happily, "younger martial brother long, have you been exposed to the knowledge of optical fiber? What are the factors that affect fiber performance? "
Long Jianhua blurted out, "material composition, structure, refractive index and manufacturing process."
Cai Kailan further asked, "what about the technology?"
"OVD, VaD, MCVD and PCVD are all based on chemical vapor deposition..."
Cai Kailan, "how many journals have you read?"
Long Jianhua scratched his head. "The teacher assigned us such a topic. In fact, we also need optical fiber, so I paid attention to this information."
Mr. Ye looked at him with appreciation in his eyes.
Bai gangpeng and Yu Kehui are still confused between a and C.
Yu Kehui stared at him blankly.
Younger martial brother long seems to know a lot about optical fiber. 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 really know something about this. I hope you can make one quickly. Someone in China is preparing it and has entered the stage of success. I hope you can start at one shot, or prepare it before them, or the performance is better than theirs. "
Mr. Ye slapped, "long Jianhua, hurry up and make the plan. There is another one available in my laboratory. You gave it to you; As for funds, I can not provide much. First provide 1000 yuan as start-up funds. "
Yu Kehui is envious.
How big is this project?
How much is the starting capital of 1000.
When the teacher asked me to study the beam splitter, the starting capital was only 300 yuan.
Long Jianhua smiled bitterly.
A thousand dollars.
So many drugs, so many equipment, less soup.
This is the current scientific research environment, and this is the greatness of this generation of scientific researchers
On the third day, he submitted the plan to Mr. Ye for review, and Mr. Ye passed it without changing a word.
As a participant in scientific research in this era, long Jianhua tried every means.
Chlorine, borrow two cans from the Chemical Research Institute.
He has a congenital advantage. He has made joint research with his uncle in the machining factory. Some special materials can go there to do some small experiments in his name.
Simple equipment, please aunt Zhao Hongying arrange processing.
Mr. Ye is a professor. He is working on major projects and chemical reagents. He goes to school to get them and to the Institute of chemical industry to borrow or buy them.
Borrow? It''s just a note. I''ll return it when I think of it.
Kong Yiji said: what about scholars, can they count as stealing?
So, can I borrow it for the country?
Just pour it from one bowl into another.
These relationships are not used... In vain.
However, those who should be invited to dinner should be invited. The smoke that should be dispersed should be dispersed. We should not treat those who are willing to help badly.
It''s all your own money.
Bottles of reagents were moved into the laboratory, and a small device was moved into the laboratory
On June 23, the last small self-made equipment was carried into the laboratory by long Jianhua.
At 3 p.m. on June 24, half a bottle of silicon tetrachloride was made.
Bai gangpeng and Yu Kehui, who are doing experiments in the nearby laboratory, put down their work and walked in.
Bai gangpeng took a hand and unloaded the equipment. "Younger martial brother long, how much did you spend on so many equipment?"
Long Jianhua smiled, "one thousand yuan is not half used yet."
High purity raw materials? Make it yourself!
Heat the silicon powder to 238 degrees, introduce hydrogen chloride gas and rectify
The color of the first bottle of product is light yellow, and long Jianhua frowns.
Purity is not good
I haven''t done experiments in person for a long time. I feel that some skills have been loose, and I still don''t control the key points; But fortunately, the brain reacts quickly.
Elder martial brother Bai, "this is much lighter than the silicon tetrachloride I saw last time. It means it''s much purer. Isn''t younger martial brother long satisfied? Isn''t there another purification process? Some impurities can also be removed at that step. "
Seeing long Jianhua looking directly at him, he said shyly, "I also happened to hear the teacher discussing with others. I listened a little."
Long Jianhua shook his head.
This is manual operation, the environment can not meet the requirements, and there will be obvious pollution at each step; Can do some pure, why not do some pure?
Yu Kehui said with a smile, "younger martial brother long, although you haven''t spent half your money, the experiment has just begun. There are still many places to spend money in the future. You should save it. For our graduate students, 1000 yuan is a lot. "
Long Jianhua smiled, "medicine is very cheap. It''s only more than ten yuan to buy ten bottles, but it will have a great impact on my future product quality... The attenuation of optical fiber, so we must keep improving at every step. "
Chemical experiments are not mass production. Small equipment and many interference factors are easy to cause instability of yield and quality; Therefore, even if the laboratory has verified successful technologies and products, the enterprise will have to grope for a long time after buying them back.
Yu Kehui shook his head. "The funds are very tight. You can''t ask too much. It''s a waste. "
Mr. ye came in and saw the silicon tetrachloride in long Jianhua''s hand. He was surprised and asked, "did you do this?"
Seeing long Jianhua nodding, he smiled and nodded, "yes, you can do some pure."
You can also make some pure
Yu Kehui''s face immediately turned red and quietly stepped back.
