Tu Xian didn't say how long he stayed in Xibao middle school, and Yang Rui didn't ask, so he found a teacher's dormitory for him to live in. He also said hello to the master of the canteen, so he stayed in the laboratory every day.

The lab is made of foam. Doing experiments is similar to cooking. Small experiments are like cooking at home. When you watch people spinning inside, the food and experiments will be done. Medium experiments are like the back kitchen of a hotel. It's better to have someone to help. The workload of the chef will be reduced and he will be waiting from time to time.

The experiment Yang Rui is doing now is even a medium-sized experiment. It is very difficult to carry on without an assistant, but with or without an assistant, he has a lot of free time, which belongs to the state of being idle when he is idle and busy when he is busy.

When he is free, Yang Rui is used to reading the papers and books in his mind. Compared with the knowledge he can get in the 1980s, reviewing the contents of later generations will have many advantages.

At least, Yang Rui felt that if he had read for 30 years, he would not have to be afraid of anything in 2014.

In any era, people who can master comprehensive knowledge are not to be underestimated.

And anyone who can study all the way for 30 years, even if he can't climb to the top of the pyramid, should also stand on the high ground.

Of course, in other people's eyes, Yang Rui is a little strange, because in their eyes, Yang Rui is just in a daze. The most amazing thing is that after a long time in a daze, he often jumps up, either writing a lot of things or doing several verification experiments.

Tu Xian can understand that Yang Rui probably simulated something in his mind.

However, this understanding is only limited to superficial understanding. After all, how complicated and difficult is it to simulate so many things and experiments in the brain?

Maybe he wanted to know more about Yang Rui's work style, maybe he wanted to know more about plant extraction, so Tu Xian stayed in Xibao middle school.

He doesn't talk about going back to work, and Yang Rui doesn't care about a free labor.

In fact, he wants to use the good labor for a long time.

"Turn on the centrifuge. Let's change two variables today and do another set of experiments." Yang Rui raised his head and ordered Tu Xian to go to work.

He has received several years of professional training, and his experimental level is needless to say. The rare thing is that he can carry out the experiment alone and replace Yang Rui in his work or supervision, which saves Yang Rui a lot of effort.

Today, Yao Yue and LV Zhi, who just came from Hedong university to fight for Yang Rui, curiously looked at TU Xian and couldn't let go.

Tu Xian's appearance is just like that of a teacher. In front of the students, he is still a little intimidating.

Tu Xian also saw that they were students. He didn't care. His hand was not slow at all.

After a while, when the experiment was ready, Tu Xian took the responsibility of assistant and gave up his position and said, "we can start."

"You do it." Yang Rui nodded his chin.

"Oh... Good." Tu Xian hesitated a little and said, "you two cooperate with me. You are responsible for the experimental record at the same time. Now it's the 15th group of experiments on extracting solanesol from waste tobacco leaves. Eight pieces of 200 grams of tobacco leaves have been crushed and added 15 times and 15 times respectively. 5 times, 16 times and 16 times. 5 times the weight of propanone solvent, soak for 20 hours, filter and distill the propanone, and then add the residue into the saponification solution... "

He looked at his watch and said, "now add different saponification solutions to each of the eight residues."

Yao Yue and LV Zhi started to weigh different solutions accurately according to his instructions.

This work is tedious and meticulous, and there is nothing special about it. Tu Xian looked around the experimental table and confirmed that all the conditions are normal. He looked back and stood next to Yang Rui, like chatting, and said, "your laboratory is sponsored by Jielikang. What will you do when you go to University?"

"Wherever I go, the lab goes." In a word, Yang Rui solved the problem that Tu Xian carefully considered.

Tu Xian frowned and said, "it's not easy to transfer experimental instruments. It costs a lot of money."

"I know."

"Is jerichon willing to go out? It's estimated that it will cost thousands of yuan for so many experimental equipment. Maybe it will be damaged. " The disassembled experimental equipment is different from the new equipment. On the other hand, some experimental equipment needs to be readjusted, or fixed, or fixed every time it moves. Manufacturers usually provide the first installation and debugging service, but it is impossible to provide installation and debugging service every time. If it's domestic equipment, it's all right. For foreign equipment, it costs thousands of dollars to send an after-sales engineer, It's not easy.

Yang Rui nodded, the money is his own, but there is no need to explain to Tu Xian. When purchasing laboratory equipment, he considered the problem of transfer. As long as the problems of packaging and transportation are solved, it will not cost too much money as Tu Xian imagined.Tu Xian smacked his tongue and asked, "where are you going?"

Yang Rui glanced at him and said with a smile, "it's not sure yet, but the laboratory may be expanded by then."

"Will it expand?"

"We will buy large-scale instruments such as electron microscopes and increase their scale." Yang Rui looked around for a week, and then said, "at that time, we need to ask teacher Tu to help us more."

"Oh, yes, yes." Tu Xian immediately replied that he hardly thought about it in his head.

Yang Rui smiles. What he wants is the present effect.

In Xibao middle school, he had Wei zhenxue as his main experimental assistant. It would be too time-consuming if he went to a new place to look for it. Moreover, the new semester of the university would be busy. Yang Rui also needed a university teacher to help.

Therefore, when he saw Tu Xian's letter on that day, Yang Rui immediately replied and did not mean to show the most advanced technology in China.

When Tu Xian came to Xibao middle school, he didn't have a few days. He was trapped in the laboratory.

It belongs to a personal laboratory, and all the experimental instruments are waiting for you to use, rather than people waiting for the experimental instruments. This kind of sour and refreshing is not for people engaged in research, which is probably very difficult to understand.

To make a comparison, doing an experiment in an ordinary university laboratory is like watching a movie for ten minutes, being called out immediately, waiting for another 40 minutes, coming back for ten minutes, and being called out again.

In the personal laboratory, the experimenters can arrange the time and instruments to their heart's content. The experimental materials can also be left in the laboratory without moving around. What's more difficult is that Yang Rui's laboratory always has experimental assistants.

Tu Xian is a lecturer in the school. No matter how he writes his thesis, he is not qualified to have an assistant. Even when he is an associate professor, he is not necessarily able to have an assistant. Now that he enjoys a free assistant in advance, he naturally feels relaxed and happy in Yang Rui's laboratory.

The most difficult thing is that Yang Rui allows him to design experiments and write papers by himself. In other words, after finishing the experiments arranged by Yang Rui, Yang Rui does not interfere in what experiments Tu Xian wants to do. This is the same as Wei zhenxue's treatment.

Tu Xian stayed for a few days without going back, mainly because of this temptation.

"If you can go to Beijing, I think it will be more convenient to do research." What Tu Xian thought was that it would be more convenient for him to take Yang Rui to Beijing.

Yang Rui said with a smile, "the management of universities in Beijing will be more strict."

"Some are strict, others won't, no matter what kind, if you study well and have achievements, the management will be loose, otherwise it will be strict, right?" Tu Xian took out some teacher's momentum, and then his tone turned sharply: "of course, if you have any inconveniences, it's very easy to ask me for help. I know a lot of people in Beijing."

"At that time, maybe we should really ask Mr. Tu for help."

"Ah! You're welcome. You should. If you have anything you don't understand, just ask me. Well, if you have any problems in the exam, the University scores in Beijing are not low. " Tu Xian was flattered and then began to worry about Yang Rui's partiality.

80 It's very common for students in the s to be partial to their subjects. It's obvious that it happens frequently. First of all, the quality of teachers is a problem. If a normal student starts to study physics and chemistry in junior high school, he will encounter a physics teacher and chemistry teacher who just graduated from a technical secondary school and enters the school through the back door, How difficult it is.

Even if the restrictions are cancelled, teaching junior high school students with ordinary technical secondary school students will not have any good results. Teaching senior high school students with technical secondary school students will be even worse. It is extremely tragic, but such things happen every day in China at this time.

When Tu Xian looked at Xibao middle school and thought about Yang Rui's identity as a second year student, he deeply doubted Yang Rui's academic performance.

In such a ravine, it's already divine to be able to write English papers and do biological experiments. You can't expect him to do more.

However, the total score will be greatly affected if the subjects are seriously biased. The total score of biology, chemistry and English is only 250.

Yang Rui gave Tu Xian a smile and said, "my grades are OK. If there is no accident, there should be no delay."

"It's better to go to an undergraduate school," he said. There is a big difference between the undergraduate and the junior college. For example, the experimental conditions, the second edition in Beijing, are all right. Although they are scattered in different departments of the University, the speed of building laboratories is also speeding up because of the funding every year. Specialist is not enough, only the key departments have one or two passable laboratories, we are still scrambling to use. In addition, there are obvious differences in accommodation, classroom, library and campus area. "Of course, it is obvious that the grades of different schools are specified by the state in the form of documents. The total funding of all China's junior colleges is not as much as that of Beijing's top universities, but the number of students varies by more than 100 times. Naturally, the average treatment enjoyed by each student is quite different.

Yang Rui nodded his head, reassured Tu Xian and said, "I'm sure I'll be admitted to university."

"We can't take it lightly. We must pay attention to it. The college entrance examination is very difficult. I said, the college entrance examination is coming soon. If you don't have a rest for a while, review well first. " Tu Xian wanted Yang Rui to go to Beijing so much.

Liu Shan, who was doing the experiment, chuckled and said, "Yang Rui is the first in the preliminary exam."

"The preliminary examination is the preliminary examination..." Tu Xian looked at Liu Shan and Lu Zhi's expression is wrong, Yi stopped, asked: "where is the first preliminary examination?"

"Hedong province is the first in the preliminary examination, and the total score may also be the first in the country." Luzhi rushed to say, and said: "the preliminary examination is the provincial ranking, the country is not ranked."

Now there is no Internet, and it is difficult for them to ask about the pre exam scores of other provinces.

Tu Xian was very surprised and regretted, saying, "so we can't be alumni."

"It's better not to be an alumni. I don't think I will have much security in college." Yang Rui's words changed Tu Xian's face again and again.
