Rebirth of the God-level Xueba

It was a very painful thing to build a laboratory in the 1980s. Those state-owned enterprises with no sense of responsibility did not care what the containers they made were, nor did they care how much the people who used them would suffer after getting these containers. .

If it is really a middle school laboratory, then the teacher only needs to explain on the stage, "Students, please note that the precision of all the containers you use is not accurate, and the conditions are limited", and the matter is over.

But when someone wants to do a research experiment, the trouble is big.

First of all, you have to assume that all the equipment and instruments are unreliable, and then measure again by yourself, and pick out the occasional ones with accurate accuracy before they can be used in experiments.

This feeling is like the legendary selection of sniper bullets. The factory made a pile of bullets, and the soldiers squatted there picking them up one by one, comparing them one by one, and then using them on the battlefield. Of course, compared to the more ancient Sino-Japanese War of 1898-1895, grinding shells in front of battle was better, but it was still strong. limited.

Fortunately, when Yang Rui was a graduate student, he also encountered such bad things. His instructor is not well-known, and the funds are naturally not much. When purchasing equipment and instruments, they usually support domestic ones. Although domestic instruments in the 21st century are much better than those in the 1980s, the accuracy requirements of the academic circle are also constantly increasing. In the end, the work of debugging the instrument can only be left to graduate students such as Yang Rui.

Yang Rui checked all the newly bought containers by doing experiments for the students, but they couldn't match each other, and he couldn't help feeling cold. The scales of beakers and the like can only show a rough idea, but What kind of trouble is going to happen if the weights of the balance are not even?

The state-run chemical equipment store also knew what was going on. When Yang Rui carried the container back, the middle-aged woman sitting under the counter knitting a sweater said without batting an eye: "Only change, not return, you have to pick it up." Pick it up in the warehouse, the things on the counter can't be bought..."

Probably because he said it too many times, when this sentence was said, it had a deliberate rhythm.

Yang Rui seemed to be hypnotized, and several students obediently sent the containers to the warehouse behind the store, and then removed the cardboard boxes from the iron shelf one by one, like soldiers picking bullets, squatting on the On the ground, choose silently.

If it is 30 years, you can buy foreign-made products if you encounter domestic products that are really inappropriate. But in 1982, let alone foreign-imported containers, it was very difficult to change a chemical instrument store. There is only such a store in the Nanhu area. It is also a branch of Pingjiang. In other words, the quality of what you see here is that of Pingjiang.

To be honest, Beijing is probably a place where the most elite scientific research institutes in the country are concentrated.

There are always some experiments that cannot be avoided.

But in the one-acre three-point land in Hedong Province, the big-name research institutes probably have their own purchase channels, while the laboratories listed in Xibao Middle School or Xibao Meat Union Factory can only buy things in ordinary stores if they want to buy things. It is obviously impossible to achieve both precision and quality.

Yang Rui could only silently squat in the warehouse to choose.

The yellow headlight hung down from the five-meter-high ceiling, it was quite dim, and the width between the iron shelves was also narrow. After squatting for a while, Yang Rui felt unbearable, and thought: Fortunately, I exercise every day If my body is the same as before, I won't be able to do anything in the next two days.

Yao Chi, who came to help together, was a clever young man. He noticed that Yang Rui changed his feet frequently, so he stretched his head to look around, and said, "Otherwise, let's move things to the door to pick them up. Open the door and move another one." Chairs, people can relax, but they are a bit in the way of others."

"Move to the door first." Yang Rui thought about it, took out a pack of Big Wild Goose Pagoda from his pocket, gave it to Yao Chi and said, "Go and smoke for the masters outside, just say we'll pick a little bit longer and occupy a space. "

"That's it." Yao Chi was less than 1.6 meters tall, but he jumped three feet high, took a cigarette and went to the yard.

Although it is only a small chemical equipment store, there are more than 20 employees in it, and there are seven or eight guards in the warehouse.

Naturally, there are so many people who have no work to do. They come and go every day, pretending to go to work. Yang Rui didn't expect them to help, but he didn't want them to hinder him from choosing.

After all, turning so many boxes of things over and over will increase the workload of others in the end. According to the style of state-owned enterprises, no matter how idle people are, they won't do extra work for you, and it won't work if they don't send out a pack of cigarettes.

Cao Baoming and another student named He Cheng in his bench press group helped Yang Rui move up and down.

Unlike Cao Baoming and Su Yi, He Cheng is a tall and thin boy who looks a little thin. When he started to practice the bench press, he couldn't even push the smallest barbell, so he put the weight on the 15kg horizontal bar. Hang up the hoop and start pushing. Up to now, I can finally push 35 kilograms. However, when picking up a heavy cardboard box, it is not as brisk as Cao Baoming.

Yang Rui tried his best to select the container, and then went to great lengths to select the reagent.

Reagents can't be tested on the spot, you can only choose a good brand. Fortunately, domestic research institutions also know how unreliable domestic products are, so many research institutes have produced so-called refined reagents in addition to analytically pure reagents, which will be more expensive and have smaller purity errors.

Yang Rui picked out the ones that looked pastable, and couldn't help thinking: "It's no wonder that those who do research should be academic authorities. If this is a national key project...no need, as long as it is a provincial key project, the things used must be all Carefully selected, this is more useful than money."

"Okay, that's all. I have to go to Pingjiang next time. It's a bit far away, and it's inconvenient to take the bus." Yang Rui greeted Cao Baoming and asked him to help deliver the selected reagents to the counter to settle accounts.

The salesperson was still busy knitting sweaters, and when he saw the first cardboard box Yang Rui sent, he actually calculated the result by heart, and said, "Eighty-five eight, no change."

After speaking, she bowed her head and did her own thing.

Yang Rui smiled and said nothing.

Immediately afterwards, there were two more "bang bangs", and Cao Baoming and He Cheng also carried the cardboard boxes and put them on the counter.

Yao Chi walked slowly, but he did not admit defeat and hugged a big box. Inside was a mechanical analytical balance with a glass cover, which was extremely heavy. When it was placed on the counter, it made a dull sound sound.

The bear girl who was making a sweater looked up in surprise, recognized the box, and said, "Did you order this?"

"Yes. I paid a deposit of 500. This is a deposit bar." Yang Rui showed the receipt to the other party.

"Your unit is quite rich, should you bring the rest of the money?" The salesman finally put down the sweater in his hand, stretched his waist, and then did a set of stretching exercises in front of Yang Rui before starting to turn over The small notebook in the drawer said: "I need to keep an account of this thing. Also, you open the box to see if there are any accessories? Leave the cabinet and find the manufacturer if it is broken. I will not be responsible for missing accessories."

It was a cadenced statement again, Yang Rui had no choice but to take out the analytical balance.

This is a clock-like device, which also has complicated components like clock gears. In order to ensure accuracy, all mechanical parts have strict specifications like clocks.

Its accuracy is one ten-thousandth of a gram, which is 0.1 milligram. It is an indispensable member in modern quantitative analysis. This guy is indispensable in almost all university laboratories.

Of course, if you go to college after 2000, the mechanical analytical balance is just a tool to embarrass people. When it comes time to do experiments, students would rather queue up to wait for the electronic analytical balance than to operate a complicated one. Mechanical analytical balance.

Yang Rui is naturally unwilling to operate this thing.

The same thing is weighed, and the electronic analytical balance gives the result instantly, but the mechanical analytical balance has to constantly adjust the knobs, beams, levers, and verniers. If it is a substance, it is nothing, but most of the time, All they encountered were mixtures.

Yang Rui learned a few classes of mechanical analytical balances when he was an undergraduate, and he wanted to smash this thing at that time.

However, in the 1980s, only mechanical methods were available for quantitative analysis. When Yang Rui recruited experimental assistants, he made up his mind to throw away all such work.

"Little brother, which unit did you buy the balance for?" A middle-aged uncle watched Yang Rui pay, and finally couldn't help but walked out from the shadows.

"West Fort Middle School."

"Do all middle schools buy analytical balances? Which company does West Fort Middle School belong to?" In the thinking of normal people, rich middle schools are naturally middle schools of enterprises.

"It's not a factory-run middle school." Yang Rui shook his head, changed the subject, and asked, "Are you from a local research institute?"

The middle-aged uncle was a little surprised, touched his thinning hair, and asked, "How do you know?"

"In the chemical store, I was wearing a shirt again, either from the school or from the research institute." Yang Rui replied naturally.

"That's right, there are only 807 and 510 in Nanhu, and there are no colleges and universities, so it can only be from a research institute." The middle-aged uncle explained to himself, with a feeling of being at the bottom of his emotional intelligence.

There are the most such people in schools and research institutes, and only this kind of place has their living space.

Yang Rui nodded habitually and said, "That's how I guessed."

"I just said... hey, you want to go back?" The middle-aged uncle wanted to imitate others, but he didn't expect that Yang Rui would not accept this at all. He was about to leave with his things in his arms, so he could only stop him.

Yang Rui said angrily, "What's the matter?"

"Somewhat."

"If you don't tell me, I can go."

"It's not a big deal... I just see that the analytical balance you bought is quite new, is it a new product from Shanghai * Shanghai?" The last sentence, he asked the salesperson.

Also middle-aged, the aunt was very busy, staring at the sweater without raising her eyes, and said, "Didn't you come to see it every day? Why do you ask?"

The middle-aged uncle was suddenly very embarrassed, and said in a nasty way: "I didn't take it apart to look."

"With your eyes, you can see through the box." The aunt's words were so sharp that no one could resist.

The middle-aged uncle bowed his head to admit defeat, peeked at Yang Rui and said, "Brother, let me discuss something with you, what do you think?"

"Oh?"

"The mechanical balance in my laboratory happened to be broken, but the funds for the first half of this year were used up. I raised some money myself, but it was not enough to buy a new one... just happened to be bought by your school. , I just thought, can you tell your principal that you can borrow it from me during your weekends."

This one is really rude, Yang Rui slandered a few words, and evaded: "It's useless for you to find me, you have to find the principal."

"Too."

"Where is the hundred-kilometer road from Xibao to Nanhu? Do you run it every weekend? Is that okay?"

"You have to run if you can, and you have to run if you can't." The middle-aged uncle had a tragic face. He didn't even use the scale in the laboratory, and he was really miserable.
