Doing scientific research is actually about finding the right path.
This is the so-called "pathfinding".
All scientific research finds the right path after experiencing several failures.
Luck cannot always be good enough to succeed just once.
Always succeed the first time, which is called copying and plagiarism, copying and pasting.
What most scientific researchers have to face throughout their lives is countless failures.
Only by experiencing failure and understanding failure can you understand why you succeed.
Only by going through this process many times can the pathfinding time be shortened.
If you fail a lot, you will naturally gain experience.
In fact, whether a person is suitable for scientific research and academics can be seen in three months.
Because the vast majority of people do scientific research and academics for no more than three months, their mentality will collapse.
You can't survive the ninth-level thunder tribulation period when the experiment always goes wrong, or the darkest moment when the thesis molecules are degenerated.
Many people just think about it once when doing experiments, and want to finish a SCI article in a month. Does this situation exist?
Yes, and there definitely is.
However, except for the academic dark forest, only a very small number of truly talented people can do it.
For the remaining people who have no talent or insufficient talent, if they want to produce something in scientific research, are there any opportunities?
In fact, there are some.
But you have to endure loneliness.
To be conservative, if you haven’t tried and missed the experimental direction 10 times, don’t feel that you can’t get the experimental results. If you haven’t revised the first paper 50 times, don’t feel that you have no academic output.
Because you should have no results and no output.
You deserve it!
Because you don’t deserve it!
To prove that you are an excellent graduate student or scientific researcher, you need time to fight against loneliness, and you need to practice non-stop, to find the way, to try and make mistakes, to correct, and to polish. of.
In this process of countless pathfinding, trial and error, correction and polishing, you will truly recognize whether you are a person suitable for scientific research and whether you can have real scientific research output. of.
But most people give up at this stage, and many people’s mentality breaks down after two or three months. This is the core reason why 99% of people say that they are not suitable for scientific research.
Because of the nature of the mind.
Those without great perseverance are not worthy of talking about scientific research.
Even a person with extraordinary talent needs this kind of character.
This is the basic condition.
Only when this basic condition is met can we talk about talent.
So, whether it is Chen Weiping or Yan Dazhou, whether it is Que Duanlin or Chen Yiquan, they understand it too well.
Basics of doing scientific researchWhat is it?
The basis is, do you dare to take the step of finding a way?
Faced with Zhang Huiguo, the first person in the industry to explain on the spot, this young entrepreneur dared to question.
This is the nature of mind.
What is the focus of scientific research?
The key point is, can you find the direction clearly and calmly on a road full of fog?
This is talent.
Chen Yiquan looked at the disciple in front of him, the leader of Xishu Province, who had personally come to seek help from his disciples, with a bright light shining in his muddy old eyes.
Unexpectedly, I found a disciple who had basic skills, character, and talent at the same time.
When he accepted Qing Yun as his disciple, he passed Qing Yun's basic skills in the school.
Originally, he wanted Qing Yun to retreat in spite of the difficulties.
After all, Qing Yun is not a student of Shu University, and this young man is also the chairman of a large group. How much time and effort does he have to study? !
The purpose is just to get involved in the chemical industry, to worship himself as his teacher, and then use the golden name of his sect to put money on his face.
You might even drag people from his sect to work for him.
Chen Yiquan has seen many people like this.
Therefore, he, who can be called a powerful figure in the academic arena, is not prepared to give up the reputation of being a leader.
You are old and can have a bad temper.
Although Chen Yiquan also knew that Qing Yun's college entrance examination results were very good, with perfect scores in mathematics, physics and chemistry.
But...
College, not high school.
Especially the broad subject of chemistry.
College chemistry is a complete subversion of high school chemistry.
The chemistry knowledge learned in high school and the conclusions you think are absolutely correct are completely wrong in the college chemistry system.
But what Chen Yiquan never expected was that after a difficult test, he found that Qing Yun's basic skills were very solid.
According to this kid, he had already learned the four major chemistry courses of the Dahua system in high school.
Inorganic chemistry, organic chemistry, analytical chemistry and physical chemistry, Chen Yiquan, who did not believe in evil, examined them one by one.
And Qingyun completely answered fluently.
In the end, Chen Yiquan even felt that this boy was synonymous with gentleness, courtesy and humility.
So humble!
Too much modesty!
How can I learn the Dahua system in advance? !
The knowledge points examined by Chen Yiquan did not deviate from the scope of undergraduate studies.
But with the depth of Qing Yun’s understanding of these knowledge points, Chen Yiquan felt that he had even completely crushed his most proud disciple, Shen Jun.
Even...
He even felt that Qing Yun was qualified to sit down and discuss things with him.
And,Many of his academic views coincide with his.
This left Chen Yiquan helpless. He could only bear witness to the provincial leaders, the richest man and his wife in China, and the leaders of Shu University. The walnut lines on his face were all smiles and he accepted this man with obvious evil intentions. A disciple who comes to gain fame.
But what made him even more unexpected was that he had worshiped his master in the morning, had the apprenticeship banquet at noon, and was dragged to Jiazhou by this traitor in the afternoon.
But the potential shown by Qing Yun at this moment made him just want to curse.
Not doing your job properly! It’s simply not doing your job properly!
What kind of company do you want to do?
Follow me and do scientific research, and I guarantee that your child will be an academician at the age of 40!
But thinking of this, Chen Yiquan could only smile bitterly and shake his head.
What the hell, others don’t need it...
Over there, Emperor Yun, who tried hard to keep his eyes "clear", nodded, and did not dwell on Zhang Huiguo’s seemingly outrageous remarks. answer.
He knows the answer.
At this point in time, looking around the world, everyone is considered a scumbag. In this field, he can say that everyone is a scumbag.
The hydrogen reduction reactions of trichlorosilane and silicon tetrachloride are both endothermic reactions. Therefore, increasing the temperature will shift the balance to the endothermic side, which is beneficial to the deposition of silicon and will also improve the crystallization properties of silicon. better.
However, the reaction temperature cannot be too high in actual production. This is because there is an optimal temperature for the solid-phase deposition of silicon and other semiconductor materials.
Once this temperature is exceeded, the deposition rate decreases as the temperature increases. At the same time, the reduction amount of impurities b and p compounds will also increase as the temperature increases, which will reduce the density of polysilicon. quality.
The optimal solution temperature for output and yield within 20 years is actually 1137°.
And he also knows why the craftsmanship of Zhang Huiguo and Hans Cat is controlled at 1100°.
After all, he is a reborn person, and his heart is actually clear.
The reason why the heat shield material of the reduction furnace is quartz glass is because the ideal working temperature range of the polysilicon reduction furnace tested by foreigners is around 1100°C.
With the improvement of technology and purity requirements, this optimal temperature is slowly moving upward.
Under the process conditions of the first generation of the improved Siemens process, that is, around the 1960s, the reaction between silicon and hydrogen chloride at a high temperature of 1100° produced polysilicon at a high rate.
Among the materials currently available, quartz glass can just meet this parameter requirement and can meet the corrosion resistance.
That’s why it’s quartz glass, so it’s 1100°.
Zhang Huiguo is a complete reproduction of the first generation improved Siemens method. There have been changes during the period, but they are only minor changes, so this temperature is suitable.
This is "why".
However, scientific research is always looking for a path.
After you have a road, do you need to find a faster road?
In real life, everyone understands that there is never only one way to reach a destination.
Not to mention the cutting and straightening of the original route. Is it possible to go by land, but is it possible by water?
Even if there is no waterway, once the technical conditions are met, there should at least be air flight.
The same goes for solving the problem of reduction furnace materials.
When foreigners first made it, there was no such material as 00i10moti maraging stainless steel.
This series of stainless steel, which looks like garbled numbers and letters, has good strength and toughness matching and corrosion resistance, and can be used in aerospace, marine construction, pressure vessel manufacturing and other fields.
At the same time, it is more resistant to high temperatures than ordinary low-carbon stainless steel.
This is the answer to the later stages of the polysilicon reduction furnace under the improved Siemens method.
Obviously, this is not the final version of the answer. The answer of the third generation and ninth edition of Yongxiang Method is a mixture of ultra-low carbon stainless steel, alloy, and ceramics.
But this is the best answer that Emperor Yun can think of under the current technical conditions.
Qing Yun let out a sigh and pretended to be surprised, "When I was reading the progress report on major projects a few days ago, Taiyuan Steel seemed to have reported a special ultra-low carbon stainless steel.
It is not austenitic stainless steel, but martensitic stainless steel. The name is quite strange, so I paid attention to it.
The safety and high temperature resistance coefficient of this stainless steel is 1200. However, ultra-low carbon stainless steel does not fundamentally affect crystal formation.
As for corrosion resistance and radiation resistance...
Mr. Zhang, this material was originally intended for use in aviation. Equipment.
Of course, I can’t say what kind of aviation equipment will be used, but if you follow the material coefficients you tell me now, they will definitely satisfy you.
You can learn about it and see if it is possible to replace it. After all, we have this kind of stainless steel in China. I think the reduction furnace process is not complicated.
I thought that once it can be used, it will be great. It has reduced our construction costs and production costs.
Of course, I am just a suggestion, the decision is in your hands."
Zhang Huiguo's eyes widened when he heard this. Then a look of surprise appeared on his face, "Really? Then this... is so economical!"
Actually, he didn't believe it.
But after all, he is an old athlete who has experienced several sports games. He is still a good person even if he has survived to this day. He knows what expressions to say and what to say in such situations.
To be honest, he likes this young man very much, but he is not very satisfied with this young man as chairman.
