Chapter 90

Although China's University Education in the 1980s was purely elite education, it was limited to financial resources and accumulation. In terms of experiment and practice, it did not necessarily guarantee that ordinary college students had more knowledge than later generations.

On the other hand, the key majors of graduate students and famous universities were pure elite education. For example, in schools like Tsinghua University, Peking University and University of science and technology, it is very common for academicians of the Chinese Academy of engineering to choose two students as assistants. This kind of training is very rare after more than ten years, and the so-called postdoctoral students can not get considerable treatment.

80 At the beginning of the s, the frequent appearance of coworkers among college students had a great relationship with the education system at that time. Experience is a very important asset, whether it's academic work, management work or official work. Thirty years later, college students may not have touched those top-level instruments until their senior year, but in the 1980s, there were many freshmen and sophomores who could get this opportunity.

Today, there are few teachers and few students. They are not professors from NiuDao to Tianjie, and they dare not say that they can have several tutors and teaching assistants to help. In 1982, we haven't started to recruit doctoral students. Postgraduates are recruited by direct promotion without undergraduate training. Therefore, many students who seem to be very spiritual may enter a Cowman's laboratory and participate in some crucial experiments once they are out of luck.

For similar opportunities, future students may have to wait 20 years.

If Jiang de graduated from Hedong university with a master's degree, Yang Rui would not repeat the experiment on the spot. Extracting coenzyme Q10 by saponification is not a great invention, but it also represents a large amount of foreign exchange. Yang Rui is in urgent need of this bucket of gold and is not willing to take this risk. In contrast, a report can't be compared at all. Even if president Zhao is not happy, it's useless.

However, since Jiang De is a chemistry undergraduate of Hedong University, it is impossible for him to know all the experimental processes of biology.

At this time, the affluence of the university is estimated to be unable to support students to do experiments in different departments. At least, ordinary students can't get this kind of treatment.

"The experiment may take a long time." Yang Rui was not ready to perform the experiment, so he was ready to sacrifice first. However, Yang Rui wrote a paper with it that day, which showed that the steps were not simple. The petroleum ether used between the steps had a more kerosene smell, which was very unpleasant.

Jiang de looked at the test tube in embarrassment and said: "I think the test tube is well sealed, otherwise, use the above logo to make preliminary data?"

Yang Rui smiles: "everyone is watching. We'd better be strict."

He also uses the mark on the test tube directly. Although the organ biochemical workshop of Xibao meat factory is backward, it is a little basic, and there will not be an order of magnitude error. For Yang Rui's experiment, he doesn't need to be accurate to less than one percentage point. Of course, he occasionally checks the content of suspended solids in the freezer, and most of the work is actually given to Wei zhenxue.

The latter is still a member of the Institute of coal science and technology, and it is not easy to appear today.

Jiang de felt a little bad. He took the test tube and thought about it for a long time. He said, "otherwise, you'd better come. I haven't used the instruments in this laboratory. I'll continue to be your experimental assistant."

"Well, let's go step by step. You should also remember that we will have to measure the content of other products later." What Yang Rui wrote is a paper on improving the output. How can we do without measuring the content.

Jiang de could not retort and nodded silently.

He thought he was several years older than Yang Rui, so he should be easily manipulated. However, he didn't expect that after Yang Rui entered the laboratory, he burst into a strong atmosphere.

In Jiang De's eyes, there are a lot of instruments. After all, except for ultraviolet spectrophotometer and mechanical analytical balance, the instruments are rough. However, Yang Rui's attitude of preparing for the experiment and assigning work reminds Jiang De of his college days.

When you come across an experimental director with higher academic level and experimental familiarity than yourself, in addition to obedience, what can you do?

Yang Rui's action was slow and standard. It took him about half an hour to complete half of the steps.

At this time, everyone's freshness has long passed. Seeing Yang Rui shake the bottle, he felt very bored.

A cadre can't help but ask: "classmate Yang, how long will it take?"

"It's going to take hours." Yang Rui wears a white coat and doesn't look back.

The cadre hesitated and said: "otherwise, let's go to visit other facilities of the school first, and then come back to see the results? Yang, can you finish it in three hours? "

"At least six hours." Yang Rui couldn't wait for them to go. Six hours later, these cadres who have had dinner and drink enough will be able to open their eyes and see people. What else can they do.Without waiting for other people to express their opinions, Ding Yaqin said with a smile: "it doesn't matter for six hours. Just give me a cup of tea. You can visit first."

Where can I visit a big school for six hours.

Seeing that Ding Yaqin is going to stay, Jiang De is suddenly full of motivation. He seems to feel that the connection between himself and the beauties from Beijing has become closer.

But Yang Rui frowned to himself. For those who are majoring in biology, there are three things to do: arson, anti-virus and anti reporter.

Because biology is so special. Physics majors make atomic bombs, contact aliens, and even more terrifying particle accelerators. I'm not afraid of the destruction of the earth. The media occasionally teases me that ordinary people don't care. At most, they oppose the nuclear power plant in front of their home.

It's not the same for biology. Cloning is a great achievement. As a result, it's criticized by the population every day. Some high school biology students who can't score 50 can also talk about human embryos and nuclei... Without the help of the media, where can these things be.

78 The human test tube baby (IVF), which began in, has also been controversial. Countless people have set the standard of ethics and attacked wantonly with the cooperation of the media. The researchers won the Nobel Prize in medicine only in 2010. Before that, 5 million couples around the world have got a successful family.

Yang Rui doubted that Ding Yaqin had a tendency of turning pink to black.

Do you need to stare at yourself for six hours to reprint a communication from Hedong Education Daily? Now it has been done for three hours, which adds up to nine hours. In the ordinary laboratory, which is small and difficult to ventilate, it is absolutely uncomfortable and unnecessary.

All the photos are taken, and there is no need to modify the reprint communication of hundreds of words.

Is it a long way to come?

Writing a black essay is certainly more targeted and sensational than writing a red essay.

If you want to be a steady journalist in your 40s or 50s, Yang Rui will think about the good. But when you look at Ding Yaqin in her early 20s, she has a strong sense of superiority. She's not sure.

Perhaps, the national newspapers will not easily publish black articles, but who can say this kind of thing clearly.

Such reports as "fake papers" and "shooters writing papers" may destroy their qualifications for the college entrance examination. The power of Chinese journalists to take out of context can not be underestimated. It will be more difficult to get rid of the stigma in the future.

"Chief Jiang, please measure the Q10 content of the intermediate, or use ultraviolet spectrophotometry." Yang Rui gave an order and continued his work, as if he really used Jiang de as an experimental assistant.

No matter what Ding Yaqin thinks, smoke with petroleum ether first.

Kerosene smoked meat, I feel it is very in line with the Chinese recipe.

Ding Yaqin covered his nose with his hand, but he didn't mean to quit.

Continuous extraction test, extraction test, and finally to the real mid-term steps.

Yang Rui thinks about it for a while. He says wait a moment. He goes out of the lab and finds he Cheng, Cao Baoming, and Liu Shan. Then he orders them to come back.

Cao Baoming is tall and suitable for the work of blocking the sight. He Cheng is familiar with the experiment and knows which steps are more critical. As a girl, Liu Shan is not particularly difficult to talk to Ding Yaqin.

In fact, the best choice is to let Jiang de and Ding Yaqin chat. However, due to the prevailing atmosphere, Jiang De's lust was quite inadequate.

In the case that the whole laboratory only knows the key points, Yang Rui secretly takes apart the experimental steps.

When mixing ethane, methyl isobutyl ketone, butanol, ethyl acetate and other compound solvents, Yang Rui first mixed half or even one third, and then finished the final preparation under the shelter of the instrument, hands and classmates.

The main theoretical basis of Yang Rui's saponification method for extracting coenzyme Q10 is that coenzyme Q in water is alkali resistant, and the unsaponifiable phospholipids containing coenzyme Q can be obtained in high yield by solvent extraction.

Therefore, the key to the problem is to find a suitable solvent which is insoluble in water.

This is a simple and tedious experiment.

If you don't know the answer, you can almost use the trial and error method. That is, one experiment after another. How about 50% sodium hydroxide? Is it better to heat 50% sodium hydroxide to 100 degrees or 80 degrees? How about a three hour bath? Or 30 minutes?

When the number of parameters reaches a certain number, the trial and error method is absolutely something that will kill the students. There are hundreds or thousands of experiments - the tutor in charge of the project will not do this kind of work, so it will only be given to the students. To be honest, a lot of domestic research results come from graduate students with a monthly salary of 800 yuan and doctoral students with a monthly salary of 1200 yuan. Cheap scientific and technological labor is also a sufficient reason for the transfer of many international scientific research institutions, just like the transfer of manufacturing industry in those years.Yang Rui's advantage is that he has formed papers, so he doesn't need cheap experimental assistants. He can directly use the answers from others, such as 48% sodium hydroxide, alkali treatment of pH12, acid treatment of pH2 and Ph1 in stages, and so on

There is no need to do wrong experiments in this repeated experiment. What should we do or what should we do, The final answer should be similar to the result of his published paper. Since Jiang de can measure the content of coenzyme Q10, the result can't be made up.

Yang Rui hopes to complete the solution ratio as soon as possible. After avoiding two items, Jiang de and Ding Yaqin also find the secret.

Jiang de quietly, but with a smile squeezed over, said: "Yang students, with the solvent work, or to the experimental assistant to complete it, the other students do not help, the laboratory is small, too messy."

He is also the leader of the Provincial Education Bureau. Although he only graduated for two years, he still coaxed and pushed people out.

At this time, a few boring cadres came back and filled the laboratory again.

Yang Rui took a look at Jiang de and Ding Yaqin, sipped his mouth, thinking: you can't blame me for not giving you face.

"Well, it's just that it's difficult to match. Let's give it to section chief Jiang." Yang Rui took the initiative to give up his position, but he took a big step in his heart.
