Chapter 91

"We are now doing reproducibility experiments, so the speed will be faster. If chief Jiang is not used to it, he can put it forward." Yang Rui's posture is very low, but behind it is full of malice.

Jiang De, who just graduated from the ivory tower, didn't know that Yang Rui would have a cunning move. He stood on the throne and said, "you can direct me to do it. It's no problem. I used to do experiments, and I'm quite proficient. "

"I think so. It seems that the Chemistry Department of Hedong university is very good. Section chief Jiang often does exercises?"

"It's not bad. There are several professors who give very good lectures. Every time someone stands and listens. You are going to take the college entrance examination this year. If you have a chance, you must have a try. The atmosphere of Hedong university is quite different from other schools. " Jiang de could not help laughing when he talked about such a happy life.

In Hedong Province, his educational background is top, otherwise, he would not easily enter the Provincial Education Bureau and shoulder heavy responsibilities.

"If we can break the key line, we must consider it." Yang Rui smiles, but thinks in his heart: in terms of the teaching conditions in the 1980s, you say you can do experiments. I believe that if you say you are proficient, don't underestimate the dark training in the research room.

After a few words, Yang Rui handed a round bottomed flask to Jiang de and said, "now, first transfer 150 ml of suspension, and then add 0. 76 grams of pyrogallic acid, followed by potassium hydroxide 2. 58 grams. It's ready by the side. Is it finished? "

"Soon." Although Yang Rui only said a few words, Jiang de was still in a hurry. These experiments are short of accurate experiments to milliliter milligram, because the weight of the final extract is only a few grams. If you scatter some carelessly, you don't need to do this experiment.

Moreover, without any help, it would be a big test for Jiang De, who had not done experiments for two or three years, to use a pipette and a mechanical analytical balance.

He didn't take part in the experiment at the beginning, but now he takes part in it again. He also feels that he remembers it.

But the reality is that the novice can't be proficient in any case.

It took more than ten minutes for Jiang De to complete this part of the work.

Before waiting for a compliment, Yang Rui said: "let's go on. Now we need to add 7 ml of methanol, mix it with 55 ml of distilled water, shake it well, reflow it in a 90 degree water bath for 30 minutes, turn on the water bath first, and remember to prepare tap water. When the water bath is over, we need to cool it quickly and pour it into the separating funnel. Can you remember? "

Jiang de was not stupid. He nodded reluctantly and said, "remember."

Without pause, Yang Rui continued: "I'll go on to say that at this stage, we need to use petroleum ether, 40 ml, and shake violently for 5 minutes. We don't have the corresponding instruments. Let's shake it with our hands. After this step, we can extract continuously and combine the extracted liquid. "

Yang Rui didn't say how to deal with the extract after he got it, because Jiang de had already begun to faint. When he mixed it with distilled water, he accidentally added a drop.

Yang Rui immediately yelled: "more."

Section chief Jiang was so excited that he could not help repeating: "too much!"

In any experiment with dropper, adding more solution is the most annoying thing. If you add less, just add more. What if you add more? If it's a mixture of two substances, maybe you can add another substance in a lazy way. But in most experiments, as they do now, there are more than two substances added in it, as well as chemical reactions.

Yang Rui glanced at the jar, shook his head, grabbed the round bottom flask, poured it clean, and said, "come again."

"That's... OK." Jiang de had no choice but to listen to Yang Rui. This kind of thing is such an answer, no matter whether he is the section chief or the president, we can't let the extra drop of water run out completely, and the drop of water doesn't listen to him.

In order not to give the final answer back to the black pot, Jiang Dewei obediently do it again.

This time, his speed has been accelerated, which shows that the foundation is really good, and the feel is a bit back.

Yang Rui won't let him do it easily. He urges him to adjust the temperature of the water bath.

When Jiang de went to take a bath with water, he made a mistake in setting the temperature and had to do it again.

In this way, not to mention Jiang De, Ding Yaqin's face changed.

Two more times, it's dark, can you do the interview happily?

Yang Rui guessed their mood and coughed: "let's come together, two people remind each other, it's not easy to make mistakes."

Jiang de nodded and said yes.

So Yang Rui quickly went to battle, stood opposite Jiang De, and began to operate various instruments. Not to mention his training in graduate school, even recently, he has done more experiments than Jiang De, not to mention doing the same coenzyme extraction experiments several times independently.In terms of speed, Yang Rui was more than twice as fast as Jiang de. the so-called mutual reminding quickly became Jiang De's desperate pursuit.

Now he is too embarrassed to say that Yang Rui is embarrassing himself, although Yang Rui is really embarrassing him.

Yang Rui's expression remained unchanged, and he had already laughed in his heart.

There are too many ways he knows to bully new people in the laboratory. The simplest one is to urge him.

The more urgent, the more wrong, the more rework, the more rework, the slower the speed, the more reason to urge.

Experiments belong to a small number of academic work. Generally speaking, smart people are suitable for studying pure theory, only using their own brains, regardless of others. In the 21st century, mathematics and theoretical physics have a sense of metaphysics. In middle school, if students have not yet found the feeling of being outstanding, they should almost understand that they are not good at mathematics and theoretical physics. The difficulty of experimental physics is much lower. If you are a little creative and have a good foundation, you can try it.

Of course, if you can't do experimental physics and still want to do academic work, you'd better study biology. After a long time in this field, you can always play a role.

Domestic graduate students have about one year's laboratory experience in their second year of graduate school, and those who do well can have two years. At this time, the newcomers, no matter in speed or other aspects, are pure and complete. They can bully as much as they want on the experimental platform.

It is rare to say that any undergraduate can counter attack as soon as he enters the laboratory. The better the laboratory, the more so, for undergraduates, instruments are not recognized, what qualifications to counter attack.

Although the domestic laboratory competition is fierce, it is not cruel after all. In the laboratories in Japan and South Korea, there are many young people who can't stand being bullied and jumping off buildings. Unlike middle schools and primary schools, most of them are not violent attacks.

Doing experiments is not as fast as others, getting data is not as accurate as others, experimental design is not as creative as others, there are many times of rework, waste of materials, overspending, backward progress, thesis can not pass, can not get diploma, ugly without friends, not welcomed by tutors... The more self-confidence and inferiority, the faster faith will be destroyed.

In just ten minutes, Yang Rui went through the process, and then said, "wash the extract with distilled water to neutral, and increase anhydrous sodium sulfate in proportion. Here's a formula to calculate. We'll discuss it later when you arrive..."

Jiang De is sweating all over his head. He can't afford to see how Yang Rui did it.

He wanted to hide his head under the experimental table.

No matter how many objective reasons there are, proud Jiang de will not forgive himself.

Ding Yaqin and others were also stunned.

In front of us, when Yang Rui did his own experiment, although he was fluent, we didn't think it was great. He thought that normal experiments should be like this.

When Jiang de went to battle and had a comparison, several talents found Yang Rui's fast and accurate.

Ding Yaqin doesn't know how to describe the strange atmosphere, but it seems incorrect to say that the "communication" of Xibao middle school is fake.

While others were struggling, Yang Rui quickly completed the most important saponification step, and then began to draw the yield curve of coenzyme Q10 on the table.

In this part, without Yang Rui's explanation, it is very professional.

Jiang Dehao easy to play a clear round bottom flask, Yang Rui's yield curve is calculated.

He peeked at it twice and didn't want to ask Yang Rui how to calculate it. He's ashamed enough.

"That's about it. Chief Jiang, check it out." Yang Rui didn't say to let Jiang de continue to do the experiment, and the latter probably didn't want to do it.

On the other hand, Yang Rui tried his best to choose a rare and complicated formula to calculate the production of coenzyme Q10, which made Jiang de feel very uncomfortable.

He studied chemistry. In his first three years, inorganic chemistry was quite close to biology. It was OK to read the simple and easy to understand formula, but he was blinded by Yang Rui's deliberately complicated formula.

In fact, if he repeated all the experimental steps, he would be able to rub something, but Yang Rui didn't give him a chance.

Section chief Jiang twisted his hair and read Yang Rui's answer, but he still had no experience.

After a while, Yang Rui said, "if Mr. Jiang is interested, we can see if the yield of coenzyme Q10 has increased by measuring the actual yield of coenzyme Q10 and comparing it with the content of suspension."

"Yes, that's right." Jiang de used ultraviolet spectrophotometry to measure the content again, but he was very skilled.Familiar with the smell of petroleum ether kerosene in the air, Ding Yaqin reluctantly buckle notebook.

"In 600 ml suspension, 82 g coenzyme Q10 crystal was extracted, which was almost 13. 67%... "Jiang de worked out the number and cried out habitually. He had been assimilated by Yang Rui's laboratory discipline.

This is the most common in a small and tense environment.

"Thirteenpoint..." a little Hedong English pronunciation, repeated the number of Jiang De.

Everyone, including Yang Rui, turned and looked at the door.

I saw a round white fat man, stretching his neck to see the experimental platform, another short Chinese translator, is trying to push forward.

"Who are you?" Jiang de shook his coat and showed the dignity of a cadre.

"This is Mr. Frankie from jerichon, UK. He is on an inspection tour in Hedong province. I am Lu Chengcai from China Pharmaceutical Foreign Trade Corporation. I am currently Mr. Frankie's interpreter and contact person. Here is my work permit. " The short translator skillfully took out a red book.

Jiang de made a pretentious inspection.

Ding Yaqin's eyes lit up like a fox and asked softly, "Mr. Frankie from Jericho, UK? What's your purpose of going to Xibao middle school? "

Lu Chengcai gave the translation in a murmur.

Frankie murmured again, then listened to the translation and said, "Mr. Frankie is investigating the medical cooperation. In the address book, there is a paper's contact address here. Is Mr. Yang Rui from your company?"

"Yang Rui?"

"Yang Rui!"

"The foreigner is looking for Yang Rui!"

Several people could not help but read out their names.

Although some people have guessed the reason, most of the Chinese expressions in the laboratory are still vivid and bizarre, like a carefully carved wax statue.
