Rebirth of the God-level Xueba

Chapter 91 British company representative

“We are now doing reproducibility experiments, so the speed will be faster. If Section Chief Jiang feels unaccustomed, he can bring it up.” Yang Rui’s posture is quite low, but behind his back is full of maliciousness.

Jiang De, a student who just graduated from the ivory tower, did not know that Yang Rui would have a trick, and he stood on the main seat with high spirits and said: “You come to direct me to do it, no problem. I used to do experiments often. Fairly skilled.”

“Thinking about it, the Department of Chemistry at Hedong University seems to be particularly good. Chief Jiang often does exercises?”

“Not bad. Several professors gave very good lectures. Every time someone stood listening. You have to take the college entrance examination this year. If you have the opportunity, you must try it. The atmosphere of Hedong University is very different from other schools. “Jiang De couldn’t help smiling when he talked about this kind of triumph in life.

In Hedong Province, his academic qualifications are considered top-notch, otherwise he would not easily enter the Provincial Education Bureau and take on important tasks.

“If you can break the key line, you must consider it.” Yang Rui smiled, but thought in his heart: As far as the teaching conditions in the 1980s were, you said you would do experiments. I believe you said you were proficient, so don’t underestimate the dark training in the laboratory.

After a few gossips, Yang Rui handed a round-bottomed flask to Jiang De, saying: “Now, first pipette 150 ml of the suspension, and then add 0.76 g of pyrogallic acid, and then 2.58 g of potassium hydroxide. , Has been matched by the side… is it finished?”

“It’s coming soon.” Regardless of Yang Rui only saying a few words, Jiang De was still in a hurry. These experiments are all precise experiments that are short of milligrams and milligrams, because the final extract weighs only a few grams. If you sprinkle some carelessly, you don’t need to do this experiment.

Moreover, without any help, one would use a pipette and a mechanical analysis balance. For Jiang De, who hadn’t been doing experiments for two or three years, it was really a big test.

He didn’t participate in the experiment when he first started, and now he participates again, and he feels that he remembers it again.

But the reality is that novices can’t fight well anyway.

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

Before there was a compliment, Yang Rui said: “Let’s continue. Now we need to add 7 ml methanol, mix with 55 ml distilled water and shake well, and let the 90 degree water bath reflux for 30 minutes. Turn on the water bath first. In addition, remember to prepare tap water and water bath. Cool down quickly when it’s over and pour it into the separatory funnel. Can you remember?”

Jiang De was not stupid, so he reluctantly nodded and said, “Remember.”

Yang Rui did not pause, and continued: “I will say next, at this step, we will also use petroleum ether, 40 ml, vigorously shake for 5 minutes. We don’t have the corresponding instrument, so we can shake it with our hands. In one step, you can continuously extract and combine the extracts.”

Yang Rui didn’t say how to deal with the extract after he got it, because Jiang De was already dizzy. When he mixed distilled water, he accidentally got an extra drop.

Yang Rui immediately yelled: “It’s too much.”

Section Chief Jiang was so excited that he couldn’t help repeating: “That’s too much!”

In any experiment with a dropper, adding more solution is the most annoying thing. If you add less, you can add more. What if you add more? If it is a mixture of two substances, perhaps you can add another substance in a lazy way, but most of the experiments, like what they are doing now, are more than two substances, and there is a chemical reaction.

Yang Rui glanced at the jar, shook his head, and grabbed the round-bottomed flask. He was completely clean and said, “Come on again.”

“This… okay.” Jiang De had no choice but to listen to Yang Rui. There is only one answer for this kind of thing, regardless of whether he is the section chief or the dean, and he can’t let the extra drop of water run out completely, and the drop will not listen to him.

In order not to give the final answer a scapegoat, Jiang De had to do it again obediently.

This time, his speed has accelerated, indicating that the foundation is indeed very good, and the feel has returned a bit.

Yang Rui wouldn’t let him do it easily, he kept urging, and kept adjusting the temperature of the water bath.

When Jiang De went to the water bath, the temperature was set incorrectly, and he had to start again.

As a result, let alone Jiang De, Ding Yaqin’s face changed.

Come here two more times, it’s dark, can you still do the interview happily?

Yang Rui guessed their mood and coughed: “Let’s come together, two people remind each other, it is not easy to make mistakes.”

Jiang De nodded dullly and said okay.

So Yang Rui quickly stepped into battle, stood opposite Jiang De, and began to operate various instruments. Not to mention his training during graduate school, even in the recent period, he has done more experiments than Jiang De, not to mention ** have done the same experiment of extracting coenzyme several times.

In terms of speed, Yang Rui was more than twice as fast as Jiang De. The so-called reminder of each other quickly became Jiang De’s desperate pursuit.

He is also embarrassed to say that Yang Rui is embarrassing himself, although Yang Rui is embarrassing him indeed.

Yang Rui’s expression remained unchanged, and he had already laughed.

There are too many ways he knows about bullying newcomers in the laboratory, the simplest one, you urge him.

The more reminders, the more mistakes, the more mistakes, the more rework, the more rework, the slower the speed, and the slower the speed, the more reason to urge.

The experiment is one of the few academic work that can make up for the poor with diligence. Generally speaking, smart people are suitable for studying pure theories, using only their own brains and not caring about other things. In the 21st century, both mathematics and theoretical physics have a sense of detachment from metaphysics. By the time it comes to middle school, if students have not found a sense of supremacy, they should almost understand that they are not learning mathematics and theoretical physics. The difficulty of experimental physics is much lower. It is a little bit creative and has a good foundation, so you can try it.

Of course, if you can’t get enough experimental physics and you want to do academic work, then you’ll be good. You can always play a role in this profession for a long time.

Domestic graduate students have almost a year of laboratory experience until the second year of graduate school, and they can do well for two years. At this time, for newcomers, whether it is speed or other, they are pure and pure. On the experimental platform, Bully as you want.

To say that an undergraduate student can counterattack as soon as he enters the laboratory, this kind of situation is really rare. The better the laboratory, the more so. For undergraduates, the instruments are not fully recognized, so what qualifications do they have to counterattack.

Although the domestic laboratory competition is fierce, it is not cruel after all. In the laboratory in Japan and South Korea, there are young newcomers who are bullied and unbearable jump off the building. Unlike middle and elementary schools, most of the attacks they encounter are not violent attacks.

Experiments are not as fast as others, and the data is not as accurate as others. The experimental design is not as good as others’ creativity. There are many rework, a lot of wasted materials, overexpenditure, lagging progress, failure to pass thesis, failure to obtain a diploma, and no friends. The ugliness is not seen by the mentor… the more confident and inferior, the faster the belief will be destroyed.

In just ten minutes, Yang Rui walked through the process, and then said: “The extract is washed with distilled water until it is neutral, and anhydrous sodium sulfate is added proportionally. Here is a formula to calculate. When we arrive, we will discuss…”

Jiang De was sweating profusely, so let’s see how Yang Rui did it wherever he could.

He couldn’t wait to hide his head under the experiment table.

The dignified graduates of Hedong University’s key majors can’t even do an experiment as a high school student. No matter how many objective reasons there are, the proud Jiang De will not forgive himself.

Ding Yaqin and others were also dumbfounded.

Earlier, when Yang Rui did the experiment by himself, although it was fluent, everyone didn’t think it was great, thinking that normal experiment should be like this.

When Jiang De entered the battle, after a comparison, several talents discovered that Yang Rui was quick and accurate.

Ding Yaqin didn’t know how to describe the weird atmosphere at the moment, but to say that the “communication” of West Castle Middle School was fraudulent, it seemed to be incorrect.

While others were struggling, Yang Rui quickly completed the most important saponification step, and then lay down on the table and began to draw the yield curve of coenzyme q10.

This part, without Yang Rui’s explanation, is already extremely professional.

Jiang De had a good time playing the round-bottomed flask, and Yang Rui’s yield curve was over.

He glanced at it twice, and was not ashamed to ask Yang Rui how to calculate it. He already felt embarrassed enough.

“It’s almost like this, Section Chief Jiang will check it.” Yang Rui didn’t say to let Jiang De continue 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 output of coenzyme q10, which made Jiang De extremely uncomfortable.

He studied chemistry. In the first three years, inorganic chemistry was more closely related to biology. It was okay to read simple and easy-to-understand formulas, but Yang Rui was blinded by deliberately making complicated formulas.

In fact, if he repeats all the experimental steps, he can still figure out something, but Yang Rui didn’t give him a chance.

Section Chief Jiang twisted his hair and read Yang Rui’s answer again, but he still had no experience.

Yang Rui asked people to come in again and started cleaning. After a while, he said, “If Chief Jiang is interested, he should not test the actual output of coenzyme q10 and compare it with the content of the suspension. You can also intuitively see the yield. Has it improved.”

“Yes, that’s right.” Jiang De used ultraviolet spectrophotometry to measure the content again, but he was very skilled.

The familiar kerosene smell of petroleum ether floated in the air, and Ding Yaqin reluctantly buttoned his notebook.

“With 600 ml of suspension, 82 grams of coenzyme q10 crystals were extracted, which is almost 13.67%…” Jiang De calculated the number and yelled habitually. He had already been assimilated by Yang Rui’s laboratory discipline.

This is most common in small and tight environments.

“…” is pronounced in English with a taste of Hedong, repeating Jiang De’s numbers.

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

I saw a round white fat man, stretching his neck to look at the experiment platform, and another short Chinese translator, trying to squeeze forward.

“Two of them?” Jiang De shook his coat and took out the dignity of the cadre.

“This is Mr. Frank from the British Telecom Company. He is investigating in Hedong Province. My person is Lu Chengcai from China National Pharmaceutical Foreign Trade Corporation. He is currently serving as the translator and contact person for Mr. Frank. This is my work permit.” The short translator skillfully took out a red leather notebook.

Jiang De pretended to check.

Ding Yaqin’s eyes lit up like a fox and asked softly: “Is Mr. Frank from Terecom in the UK? What is your purpose in coming to Westburg Middle School?”

Lu Chengcai grumbled to the translation.

Frankie whispered again, and then listened to the translation: “Mr. Frankie is investigating medical cooperation. In the address book, there is a paper contact address here. Mr. Yang Rui, does it belong to your organization? ”

“Yang Rui?”

“Yang Rui!”

“This foreigner is here to find Yang Rui!”

Several people couldn’t help but read 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.
