Chapter 630

The specifications of the commendation meeting have been upgraded very quickly. It took only two days for the program to become an important work of the Department at the end of the term and then an important work of the school.

At the same time, the number of people participating in rehearsal is also increasing.

Originally, eight people were selected by the biology department, but now it has become a school wide commendation meeting, and the number of people has increased to more than 90 at one go. This is to avoid the number of people exceeding 100.

Of course, rehearsal time has increased.

Although the eight people who will be honored in biology department are happy, they still feel that rehearsal is hard.

Xu anqing had a lot of opinions. At the end of the day, he couldn't help asking, "why didn't Yang Rui come?"

He pointed to the banner overhead to show that he was reminded.

Today's person in charge is no longer a cadre of the student union, but a counselor of the Department of biology, Bai Shanwen.

He gave a "um" sound, shaking the mole on his mouth without any expression, and said: "Yang Rui is busy. When we have finished rehearsing, he will come back to rehearse."

"We're busy, too." Xu anqing was so upset that he let it out.

Bo Shanwen said with a smile: "I know that everyone is very busy, so we should seize the time to rehearse, right. Yang Rui is not at school now. It's no use calling him. In a word, I will let him not hold us back. "

Speaking from a different angle, it sounds like Bo Shanwen is very considerate of everyone.

Xu anqing naturally won't be fooled by him, but in the current situation, he can't do anything.

Helpless depression will turn into anger.

Xu anqing kept comparing himself with Yang Rui. For many times, he asked himself, "what's the difference between me?"

There is no answer to this question, and as we continue to rehearse, Xu anqing has to follow suit.

However, Yang Rui followed Professor Cai and demonstrated the PCR instrument to him in the laboratory.

As a practical technology in the academic field, it is just like the practical technology in the business field. It is needless to say that it has no clear function.

It's like a refrigerator. If it's simple, it's just for refrigeration. As for what to do with refrigeration, this is a household or commercial skill. You can use it to put leftovers, make ice cubes, drink wine, and put bacteria in the culture medium.

What can also be taken out thousands of times is X-ray, orthopedic film, oil painting and DNA.

When such a technology just appeared, it was impossible to say who could foresee it.

It can only be said that people can see that it has a strong scalability.

No one can predict whether to expand to the extent of oven, refrigerator, X-ray or computer. In many cases, further development also needs creativity, just like the inventor of water bath pot, who does not know that the water bath pot can be transformed into a PCR machine.

Of course, there is no patent conflict between PCR instrument and water bath, and the latter can't even be included in it, because the core of the patent is not hot water heating or constant temperature water control.

Even after 30 years, the potential of PCR instrument has not been fully exploited. In other words, Yang Rui doesn't know how much PCR instrument can do in the end, which is exactly the strength of PCR.

In fact, PCR won the Nobel Prize in 1993, only four or five years after the advent of PCR instrument and seven or eight years after the invention of PCR technology. Before PCR won the Nobel Prize, people in the industry constantly predicted this

In a word, the development of PCR, just like its function, starts from a very small point, And the expansion is much faster.

Before that, academician Cai thought that PCR was a good technology, but he didn't think it could be any better. In addition, the PCR instrument has not yet been made, so academician Cai, whose research field is not in gene, didn't think much about it.

Now, Yang Rui's achievements in the "International Conference on Genetics" make academician Cai have to study PCR well.

For a scholar of his level, a good study is not only about reading the literature, but also about doing two experiments.

Professor Cai made an appointment with Yang Rui to come to Huarui Laboratory for a whole day.

Yang Rui is also waiting respectfully. Up to now, he is not worried about divulging some experimental contents, so he is very generous to set out all kinds of instruments.

Duan Bo and others are also water instruments, ready to do multiple experiments at the same time.Yang Rui started with the simplest plasmid amplification, demonstrated to Professor Cai, and said: "after we do some further research, we should be able to copy human DNA, such as extracting DNA from hair and then amplifying it. At present, we can't do it yet..."

"Even so, your research has been approved by Professor Evans." Professor Cai said with a smile: "Professor Evans's research in genetics is impressive, and his judgment is also famous in the industry."

"Is it?" Yang Rui knows that Evans is a cow, but he doesn't know the direction of his cow.

Professor Cai nodded and said, "can I do it myself?"

"Oh, please." Yang Rui quickly let out the place, and then called Huang Mao to do guidance. After all, he is a student and is not suitable to direct Professor Cai.

Professor Cai carried on the experiment step by step. During the break, he observed the Huarui laboratory.

Yang Rui was looking at the mood, whispered: "do you see any problems in the laboratory?"

"No, it's very good. It costs a lot." Professor Cai said, "it's just complementary to your ion channel laboratory."

At present, Yang Rui's ion channel laboratory is still a high-quality product. He bought expensive instruments to do some experiments that he didn't often do. In contrast, Huarui's laboratory is a little bit built up. Naturally, it has a lot of things to do, and it is able to undertake many groups of experiments, so it has a tendency to be a big laboratory.

Yang Rui shrugged his shoulders and said with a smile, "there's nothing I can do about it. If you give me another million yuan, I can buy a set of good instruments."

"Good." Professor Cai replied with a smile.

"Well, well?" Yang Rui stares at Professor Cai: "is the school so rich?"

It's not easy for a department of Peking University to raise millions after 2000. I'm afraid it will be 10 years before it can easily allocate millions to a laboratory. Now, in 1984, academicians can see millions. Like Professor Tang Ji, he can apply for a national laboratory with millions of funds in a year.

Professor Cai did the experiment without looking up and said, "I don't need to give you money. If you can pass the national achievement recognition, I can help you find money."

"How many can we find?" As soon as Yang Rui listens to the three words "national level", he doesn't know that it's difficult to do it. First, he asks about the benefits.

Professor Cai is used to saying: "at least one or two hundred thousand, at most three or five million, depending on how to evaluate."

"How much do you think I can assess?"

"It depends on the early work." Professor Cai didn't say much, but he concentrated on the experiment again.

In the afternoon, Professor Cai picked up the experimental record he had just written, looked through it and said, "Yang Rui, let's go out for a walk?"

"Oh, well, it's a little stuffy inside." Yang Rui followed Professor Cai out of the door.

Outside the Huarui laboratory, it is still a wilderness. They walked up the path to a hill, and then they heard Professor Cai say, "do you have a high income in Huarui laboratory?"

"Ah... It seems OK." Yang Rui doesn't know why.

"Is there a burden at home?"

"Well, I don't think so."

Professor Cai nodded and said, "I've read your files. Your father is the Secretary of the township party committee. If he doesn't have the burden, you don't have to worry about anything, do you?"

"Basically."

Professor Cai nodded and said, "the economic foundation determines the superstructure. I'm here to tell you that in private, it's difficult for poor children to do scientific research, especially those from poor families in China. It's too hard for them to do scientific research."

Yang Rui was silent.

Professor Cai continued: "to do scientific research, you have to study. During your study, you not only have no income, but also have expenses. When you graduate from University, you are 21 or 22 years old, and you are 24 or 25 years old. At this age, if you go to the government or the factory, you will have a bright future. But in the scientific research field, undergraduate education is not enough... Our domestic conditions are relatively poor, Few people can go to graduate school or Ph.D. school. Going abroad is the only way out. However, even if you come back from abroad, it's not easy to get a lot of income. During this period, you can't take care of your family. As an old Chinese saying goes, "if parents are not traveling far away, it's because they want to support their children and their parents are not there."

What Professor Cai said, In fact, Yang Rui has a lot of feelings. The reason why he did not continue to study after finishing his master's degree is that on the one hand, the road of scientific research is difficult, and on the other hand, he has never been free from economic pressure.

China's doctoral students do not delay for a year, and they all graduate at the age of 27 or 28. But in this ideal state, none of the ten doctors has a doctor's degree. Most Ph.D. students, who are about 30 years old, are still struggling in the laboratory with the title of doctor.Postgraduate and doctoral education are different from undergraduate education in that they don't have much time and energy to work part-time. Therefore, almost all doctoral students in China live with subsidies ranging from 600 yuan to 1200 yuan.

30 A 20-year-old man lives with 1200 yuan. If he talks about a girlfriend, it's hard to imagine. If the family still has the burden, the whole doctor's career will be miserable.

On the contrary, if there are some subsidies at home, it will be easier and easier to read a blog.

Professor Cai is not ready to ask Yang Rui to answer either. He looks at the young Yang Rui and after digesting his own words, he says, "the reason why I say this to you is that it costs a lot of money to evaluate a good achievement. So here are two questions. First, do you have any money? Second, are you willing to spend it

Yang Rui finally understood and asked in a low voice, "must we spend money?"

"It can't be said that it's a must. It's possible to be successful without spending money, but..." Professor Cai said with a smile: "if you want to spend millions of money, I suggest you don't waste your time at will."

"The national level achievement recognition, if recognized, is to recognize my invention right, discovery right, patent right, and so on, right?"

Professor Cai didn't care about what he said. He said with a smile: "more importantly, if you want to evaluate your achievements in the future, you need achievement recognition. Many awards will have requirements, such as provincial and ministerial achievement recognition, county and district achievement recognition and so on. The national achievement recognition is the most strict and useful. Your laboratory rating and so on can be used."

"But PCR, I did it in Huarui lab."

"The identification of the unit is on the one hand, and the identification of the individual can be carried away. Otherwise, if I change to another school, should I start from the beginning?" Professor Cai began to laugh.

Yang Rui breathed a sigh and asked, "how much do you want to prepare?"

The landlord also has no surplus food. He is also short of money before he takes back the PCR bill or dividends.

Professor Cai shook his head and said, "it's not only about money, but also a lot of spirit. You have to be prepared."
