Rebirth of the God-level Xueba

Chapter 62 Absorption coefficient

Yang Rui also had the experience of borrowing experimental equipment, but instead of lending the equipment out of the laboratory, he used it in someone’s laboratory.

Generally speaking, the equipment purchased by the teacher from the same school can be borrowed occasionally. If it is purchased uniformly in the school and placed in a teacher’s laboratory, it will be more comfortable to borrow. .

But in any case, the use of experimental equipment is a bit of an open mouth begging, and the people in the ivory tower are actually the least willing to ask for help.

When Yang Rui was a graduate student, he would be closed door from time to time. Sometimes it was people preparing to use instruments, sometimes it was troublesome for students who took keys, and sometimes it was impossible for the teacher who took the keys to make beasts at home. Sometimes the instructor with the key can’t make a beast in the office, and sometimes the instructor with the key makes a beast in the laboratory without opening the door…

No matter what kind of closed-door soup, when you eat it, you will always feel hot lips, hot intestines, and sometimes, you will feel hot chrysanthemums.

Yang Rui didn’t know if anyone was accustomed to eating closed doors, but he had tasted a wide range of closed doors in a few years, but he was still not used to it.

Sometimes, an experiment is at a critical juncture, and I am excited and nervous to take the materials to other laboratories, and I am excited and nervous waiting for people to borrow the instrument after finishing the home. If they eat the closed door again, it will be uncomfortable. , I feel a bit shameful.

But you can’t help it. The school is not good enough, the college is not good enough, the tutor is not good enough, and you are not good enough. That’s how it is.

Sometimes Yang Rui also thinks: “When I become a big cow in the future, I will also buy a floor-to-ceiling instrument, whichever I want to use, and when I want to use it…”

Unfortunately, the experimental equipment is more expensive than the house, and there are too many graduate students who want to be great. Yang Rui did not realize that illusion after all.

Instead, in the 1980s, Yang Rui saw the hope of building his own laboratory.

On the one hand, he has the need to build his own laboratory; on the other hand, ordinary instruments are relatively cheap now. Of course, in terms of domestic economic conditions, the instrument is not cheap, but it is still affordable.

The most important thing is that now that publishing articles, the requirements for becoming a big cow have become lower. You must have a name and a surname in China, and you can write high-end papers without purchasing the most advanced international instruments. This opportunity was in the early 1980s. For several years.

In fact, there are very few researchers who continue to do research during the ten-year catastrophe, and even fewer can keep up with the progress of foreign research. Everyone is catching up and learning the latest foreign research. Simply put, all Chinese researchers are here. Copy foreign research.

Those who can speak English are more advanced, and those who don’t know English can copy the second copy.

If you don’t copy it, you can’t do it. The domestic scientific research level in the 1960s was already weak, and then let the foreign countries take the lead for more than ten years. If you don’t copy the latest foreign research, the research is repeated research, and it is meaningless.

Of course, some people don’t care and are willing to do repeated research, so-called “self-reliance and fill the gaps in the country.” This kind of achievement is also a special person in a special period.

In contrast, doing theoretical research is naturally happier than doing experimental research.

For example, if a mathematician wants to understand the latest progress in foreign countries, he only needs to buy a journal and read it. If he can read it, even if he keeps up with the research progress, he must repeat the experiment if he can do experimental physics or biology. It is okay to do a few experiments. , But if you don’t just read journals in an experiment, you won’t be the essence after all.

For Yang Rui, who already has financial resources, it is not expensive to conduct experiments that meet the level of China, but for ordinary researchers, it is not necessarily.

The middle-aged uncle looked at Yang Rui blankly, and saw that he hadn’t spoken for a long time, and said pitifully: “Do you think this will work, I will move out on Saturday afternoon, Monday night, just before morning, I promise to send you back. ”

Hearing what he said was pitiful, Yang Rui was also a little softhearted, saying: “You can introduce yourself first.”

He didn’t agree first. After all, it is not convenient to borrow experimental equipment. What’s more, things like analytical balances are extremely easy to damage when they are moved around. That is, a person with low EQ does not care about the demands of acquaintances.

Only then did the middle-aged uncle woke up and sneered: “Look at me, I’m from the 807 Institute, engaged in organic chemistry, and my surname is Wei Mingzhenxue.”

“Then what experiment are you going to do?”

Wei Zhenxue hesitated and said, “Solvent extraction of coal.”

It seems that Yang Rui can’t understand, Wei Zhenxue explained: “It is to study the extraction performance of coal with solvents, to investigate what additives and auxiliary methods can be used to change the extraction of coal, usually ultrasonic, electromagnetic radiation and chemical treatment…”

“The solubility of coal.” Yang Rui summed it up in one sentence.

“Yes… this is it.”

“I thought 807 was engaged in chemistry. It seems to be the Institute of Coal Science?” Ordinary chemical researchers would not touch coal.

“Nanhu Coal Research Institute.” Wei Zhenxue lacked the goodwill of the unit, took off his glasses and rubbed his eyes, and said: “You know my name, and you know my work unit. Now you can lend me the analytical balance. Right?”

“You…” Yang Rui clicked on him with a smile, and then refused with a smile: “No!”

“why not?”

“I know the name and work unit of many people, why should I lend it to you?” Yang Rui asked back. He actually looks down on coal chemistry. The domestic desire to engage in coal energy is understandable, but from the experience of 30 years later, coal really lacks the value of vigorous development, especially after the fog in Beijing, coal has once again entered a long period of time. It’s hard to say when to restart.

Researching coal chemistry in the 1980s was not a waste of time, but it was not worth investing heavily.

Wei Zhenxue, who was not good at talking, was dumbfounded, and said, “You asked me several questions, didn’t you just make sure you can lend me? I told you all, why are you not satisfied?”

“There are some.” Yang Rui motioned to He Cheng to take the analytical balance away, and at the same time stopped Wei Zhenxue, who was chasing the analytical balance, slowly saying: “The Institute of Coal Research is a rich unit, even if your analytical balance is broken, I will not I believe there is only one analytical balance in your house, why should you borrow me?”

Wei Zhenxue’s voice became smaller: “The other analytical balances are all occupied.”

“So that’s it.” Actually, Yang Rui could guess something without him. This Wei Zhenxue’s EQ is so low that it is not much different from those who only read Mao’s selection all his life. It is natural to mess up the staff in the research institute.

In many people’s impressions, the university seems to be a white ivory tower, the research institute is like a green haven, and the peaceful footsteps of a beautiful girl…Perhaps for students and masters, the university can indeed be called an ivory tower, at least it is a mouthful White teeth, but for ordinary faculty and staff who are still chasing fame and fortune, the university is even more like the corpse of an elephant.

Wei Zhenxue’s analytical balance is broken, and no one is obliged to lend it to him. The research work is very heavy. Inspiration comes at any time. It is the most wonderful experience to use the laboratory at any time. It is not impossible to lend it to others, but like Wei Zhenxue’s weird personality People, it’s really not a good “roommate”.

Yang Rui is also not a person who likes Wei Zhenxue’s character very much. The so-called Joe, who is holding Einstein, who writes articles in core journals, is a type of person who is difficult to deal with.

If you want to share the analytical balance with this middle-aged uncle for a long time for no reason, it will definitely not be a good memory.

Yang Rui’s heart became hardened just now, and said, “Analytical balances are not suitable for frequent transportation. It is not a good idea to lend you. It is the same for you to find the principal.”

“How do you know what your principal thinks?” Wei Zhenxue was also a strain, and simply followed them.

Cao Baoming stroked his arm and asked, “What should I do?”

“Let him follow, and we will leave in a while.” Yang Rui and the others got on the tricycle first, then took the shuttle bus back to Xi County, and then back to Xibao Town from Xi County.

It was such a long journey, but Wei Zhenxue never left.

When he arrived at school, Yang Rui couldn’t rush people, so he let him into the laboratory.

The slightly dim large tiled house was originally used as a warehouse. When Wei Zhenxue saw it outside, he expressed his contempt and said unabashedly: “It’s a shame to give you such a good analytical balance. ”

“What do you mean by giving it to us? We bought it.” He Cheng is a short head, but his voice is high, as if the retort voice can lift the tiles off.

Wei Zhenxue shrank his neck, followed Yang Rui, walked into it quickly, and said, “The same thing I bought… ah…”

“The feeling inside and outside the room is different, right.” Yang Rui stood in front of the experiment platform and said with a smile.

Wei Zhenxue nodded blankly.

There are four incandescent lamps in the room, illuminating the inside.

The test bench is gray and white, and the surface is terrazzo, which looks smooth and shiny. There are also sinks of the same material and rare water pipes, which can’t help showing a unique temperament.

The entire laboratory was arranged in accordance with Yang Rui’s requirements. As the analytical balance was placed on a special instrument table, the Xibao Middle School laboratory became more upscale.

Wei Zhenxue was a little surprised, and said sincerely: “It’s pretty good.”

“People depend on clothes, horses and saddles. The rooms are well decorated. If you want to find the principal, go to the dormitory area. We are about to start preparing for the experiment.” Yang Rui wanted to send him out.

Wei Zhenxue suddenly enlightened and said, “I’ll help you prepare.”

With that, he took the initiative to come to the instrument station to help debug and analyze the balance.

Yang Rui is happy to have someone help. It is very troublesome to clean up a laboratory, especially in the initial stage, when the students don’t use anything, he has to do it himself.

Wei Zhenxue not only helped with the work, but also taught other students how to do it, which immediately relieved Yang Rui’s pressure.

Moreover, he persisted for two days surprisingly.

“Isn’t it a madman to survive?” Yang Rui expressed admiration for Wei Zhenxue’s perseverance, but he was still true to color and started his own experiment on his own.

He wants to revise the determination method of coenzyme q10, more accurately, revise the absorption coefficient of coenzyme q10.

Until 30 years later, the content of coenzyme q10 was often measured by ultraviolet spectrophotometry, and the basis of this method was the absorption coefficient of coenzyme q10.

In simple terms, it is how much light coenzyme q10 absorbs.

As we all know, in terms of color theory, black absorbs the strongest light and white absorbs the weakest. However, the degree of light absorption of a substance often needs to be measured through a series of experiments.

Generally speaking, the absorbance is measured by an authoritative organization or person, and others can use it according to it. It is exhausting to measure it every time.

In the domestic drug standards used in various provinces and cities in the 1980s, UU reading www.uukanshu.com on the absorption coefficient of coenzyme q10 is copied from foreign books in the 1950s. Yang Rui clearly knows that this part of the content is out of date.

When he was looking for information in later generations, he encountered literature in the 1980s. When he saw the description of the content of coenzyme q10, he would consciously put a question mark. If he wanted to use the data, he had to do the experiment again to determine it himself.

Therefore, Yang Rui clearly knows that the absorption coefficient of q10 currently used in China is low.

The reason for choosing this experiment as a breakthrough is that the absorption coefficient is a certain value, a direct feedback from nature, and it will not change due to authority or bureaucracy.

Yang Rui tested it and it was correct. No one could refute this when writing a paper based on it. For a high school student, this kind of article that is not too difficult, but also has a little importance, is too suitable.

He Cheng and others obediently helped, only Wei Zhenxue, who was teaching the students to use the instrument while watching Yang Rui’s proficient operation, looked rather reluctant to think about it. You are reading, if any!
