Chapter 67 Metallurgical Laboratory (for follow-up, recommended)

Today is very strange, Wang Xu received a call from Professor Yan early, and Wang Xu hurriedly called back. He really wanted him to go to the department as soon as possible. His request to borrow the metallurgical laboratory was answered last time.

Wang Xu kissed Wang Fei who was still sound asleep, but Wang Fei just turned over and hugged him again, continuing to sleep soundly.

This girl has been a little lethargic lately, it's too hot, Wang Xu didn't bother Wang Fei yesterday, and fell asleep with his arms around her after two bouts of hasty exercise.

Why still can't get up now, it should not be said.Wang Xu took the girl's hand and felt her pulse. There was nothing wrong with it.

In fact, Wang Xu still underestimated the consumption of certain things to ordinary people. This is another misunderstanding caused by traveling through different worlds. His evaluation of normality is no longer normal.

No matter, since it's no big deal, just sleep if you like to sleep, it's okay anyway.

Last night, Wang Fei told him that she received a call from her teacher asking her to go back to Xiangjiang recently and introduce someone to her.

Her teacher spoke in a mysterious way, didn't say who it was, just said it was a good thing, which made Wang Fei flustered and didn't know who to meet, so she discussed with Wang Xu and asked Wang Xu to accompany her Let's go back to Xiangjiang together.

Of course, Wang Xu has no objection. He started to apply for a passport very early, and he also applied for a Hong Kong and Macau passport when he was running a company. There is no obstacle to going to Xiangjiang, so just go.

It's just that the laboratory that I just borrowed from the teacher has already got news, trouble.

Looking back, Wang Fei will discuss the time of going back with the teacher today to see if it can be delayed for a few days. If it is not possible, Wang Xu can only go there a few days later.

This time, Wang Xu and his teacher borrowed the metallurgical laboratory for his method of preparing oxygen-free copper.As for oxygen-free copper, he checked the information in the university.

This is not a new thing, although the price is not cheap, but it is not considered sophisticated.It is produced both at home and abroad, and the purity of foreign countries is higher, but there is no ban on sale. It can be bought, but it is expensive.

This thing is mainly used in places such as audio wires. In the production technology of microphones, it is not uncommon to see oxygen-free copper.

However, it is a bit rare to be able to list the preparation of oxygen-free copper as a separate technology by the system.

So Wang Xu really plans to experiment with the preparation method provided by the system, and the raw material is oxygen-free copper with 4 nines. This is interesting, and oxygen-free copper is prepared with oxygen-free copper.

Wang Xu is half-baked about metallurgy and knows a little bit, but he is all Fan Fan.It can only be seen that the purpose of some steps is further purification, because he used a vacuum chamber.

But there are still a few steps, so I really can't see what it is doing.

I don't even know what changes those steps can make. It is definitely not a simple purification, because just purification should not make the system stand alone.

Wang Xu asked his seniors from the Department of Materials to help him, and visited the metal laboratory of their department. The equipment was sufficient, and there was no need for equipment modification.

In other words, these steps are not complicated, and they are not even beyond the scope of a better metallurgical laboratory.You know, in this era, there are no top metallurgical laboratories in China.

I don’t know how Professor Yan persuaded the Department of Materials to simply lend the laboratory to Wang Xu, let him use it for a few days under the guidance of a senior brother, and the price was still, um, 2000, the same as the electrical laboratory.

Anyway, when Wang Xu rushed to the department office, Teacher Yan even prepared the key card for entering and exiting the laboratory building. Let's call it a key card, but it is actually a note.

At this time, there is no IC access control card like the later generations, and there is not even a photo on the door card.It's just a small note with the entry and exit voucher printed on it, and a handwritten name.

It is mimeographed, and it is said that the color of the ink is changed every week. It is a bit like the tickets for entering and exiting dance halls and bars in later generations, only rougher.

Now the anti-counterfeiting is really simple, just a slip of paper, with the student ID card, you can enter.

There are a lot of valuables in the metallurgical laboratory, and it has been a miracle of management that nothing has happened for so many years.

Professor Yan watched Wang Xu put away the key card with a smile, and then said kindly:
"I said hello to Professor Bian of the Department of Materials Science and Technology. He happened to be in charge of the laboratory. I told him about your affairs. He read your experiment plan and was very interested.

Don't worry that he won't steal your results, but don't forget to report to him if you get any results later. "

"Okay, Professor Yan, thank you very much, this is a silk scarf I painted myself, and I give you one.

You can use it for your wife. The tailor shop at home only makes women's clothing, and there is nothing for men. "Wang Xu took out a hand-painted silk scarf wrapped in a kraft paper bag and handed it to Professor Yan.

Professor Yan was not too polite. When he heard that it was made by himself and there was a tailor shop, he knew that the student's home was not bad, so he took it and opened the package to have a look.

Of course, people are not so sensitive these days. Most people still regard giving gifts as a favor, not as a bribe.

In Wang Xu's previous life, a classmate gave the teacher a sack of sweet potatoes, which was carried from central Henan Province. It is said that everyone in the teaching and research section shared several catties.

"Your silk scarf is very beautiful. Did you draw it yourself? Is it true or not? This ink landscape has a taste."

"Well, I painted it. This ink is not ordinary ink, it is a very special dye, which is different from painting.

It can be regarded as a kind of ancient law inheritance, I am not bragging, this thing, you have no place to buy it if you want to.This one is not afraid of washing, you can wash it with warm water and gently rub it, and it will not fade. "

Wang Xu casually chatted with Professor Yan. After contacting Professor Yan a few times, he found that he was easy to deal with, and he didn't like crown things very much. It was more in line with his temperament to talk and act casually.

Professor Yan went to university in the 50s, and was sent to study abroad by the government from the very beginning.

In Ugly Country, he slipped away a lot in his childhood, and returned to China in the early 80s. Looking at his habit of opening gifts, he knew that he was developed overseas.In Huaxia at the moment, it would make people feel impolite to not open the gift immediately after receiving it.

But Professor Yan took it apart casually, and it still makes you feel quite natural and a very interesting person.

Judging by his smooth habits, it is estimated that his family also received Westernized education very early, but this is purely Wang Xu's guess.

There are many teachers and professors in Shuimu who were left before the liberation in the early years. At that time, scholars were really not something that ordinary people could afford.

The earliest people who came into contact with Western culture and customs were rich and noble families. After being passed down, some scholarly families formed, such as Emperor University, Shuimu, and Huake Academy.

At least in this era, the so-called schoolboy atmosphere is not very serious. After all, everyone is second-rate, so don't laugh at anyone, and bury your head in pursuit is the kingly way.

There are no tigers and monkeys in the mountains who dominate the king, but they will really be laughed at. At this moment, there are still many old scholars leading the team at the front line. There is no way, the talent gap is too serious.

The soil doctors who have been retrained after the reform have just graduated, and it is still early to take the lead.

There are still quite a lot of government-sponsored overseas students like Professor Yan who come back, which is much higher than the proportion of those who went out at their own expense.In the 90s, they could be said to constitute the core backbone of Huaxia universities.

But having said that, there was really no shortage of positions for them at that time. They were associate professors as soon as they came back, and they were promoted to professors soon.Whether it is a teaching position or an administrative position, the road is going smoothly.

It's not like later, if you don't make achievements overseas and get some awards, there is no place to accept you when you come back, and then you scold you for being unpatriotic. Does it mean that you will be patriotic when you come back and twist the screws?

Forget it, let’s not talk about this, there are too many taboos.
