Chapter 67 Metallurgical Laboratory (seeking further reading, recommended)

Today is very strange. Wang Xu received a page from Professor Yan early. Wang Xu quickly called back and really asked him to go to the department. His last request for borrowing the metallurgical laboratory was responded to.

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

This girl has been a little lethargic lately. It's too hot. Wang Xu didn't bother Wang Fei yesterday. He exercised twice and then fell asleep with her in his arms.

Why can't I get up now? I shouldn't. Wang Xu took the girl's hand and felt her pulse. There was nothing wrong.

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

No matter what, since it's nothing serious, just sleep if you like, it won't matter anyway.

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

Her teacher said it mysteriously. She didn't say who it was, but just said it was a good thing. This made Wang Fei anxious. She didn't know who she was meeting, so she discussed with Wang Xu and wanted Wang Xu to accompany her. Let’s go back to Xiangjiang together.

Of course Wang Xu has no objection. He has applied for his passport very early, and also applied for a Hong Kong and Macao pass when he opened a company. There is no obstacle to going to Xiangjiang, so just go.

It's just that there is news about the laboratory I just borrowed from the teacher, trouble.

Wang Fei will discuss the time to go back with the teacher today to see if it can be postponed for a few days. If it doesn't work, Wang Xu will have to wait a few days to go back.

Wang Xu borrowed the metallurgical laboratory from his teacher this time for his method of preparing oxygen-free copper. He looked up information about oxygen-free copper in college.

This is not a new thing. Although the price is not cheap, it is not highly sophisticated either. It is produced both at home and abroad. The purity of foreign products is higher, but there is no ban on sales. It is completely available, but it is expensive.

This thing is mainly used in audio wires and the like. It is not uncommon to see oxygen-free copper in microphone production technology.

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

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

Wang Xu is a dabbler in metallurgy. He knows a little bit, but he is just a 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, and you really can’t tell what they are for.

I don’t even know what changes those steps can achieve. It will definitely not be a simple purification, because just purification should not allow the system to pick it out alone.

Wang Xu asked his seniors in the Materials Department for help and visited their department's metal laboratory. The equipment was sufficient and there was no need to modify the equipment.

In other words, these steps are not complicated and do not even exceed the scope of a relatively good metallurgical laboratory. You know, in this era, there are, well, no top metallurgical laboratories in the country.

I don’t know how Professor Yan persuaded the Department of Materials to simply lend the laboratory to Wang Xu and let him use it for a few days under the guidance of a senior. The price was still, um, 2,000, the same as the electrical laboratory.

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

At this time, there was no IC access card of later generations, and there was not even a photo on the access card. It's just a small piece of paper with the entry and exit voucher printed on it and a handwritten name.

Mimeographed, it is said that the ink color will be changed every week. It is somewhat similar to the tickets for entering and exiting dance halls and bars in later generations, but it is rougher.

Nowadays, anti-counterfeiting is really simple. You can enter with just a piece of paper and your student ID card.

There are a lot of valuables in the metallurgical laboratory. It is really a miracle of management that nothing has happened after 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 from the Department of Materials, who happens to be in charge of the laboratory. I told him about you, and he read your experimental plan and was very interested.

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

"Okay, Professor Yan, thank you very much. This is a silk scarf I drew myself, and I give it to you.

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 brown paper bag and handed it to Professor Yan.

Professor Yan was not polite. Hearing that he had made it himself and that there was a tailor shop, he knew that the student's family conditions were not bad. He reached out to take it and opened the package to take a look.

Of course, people are not that sensitive these days. Most people still regard giving gifts as a favor, rather than offering or accepting bribes.

In Wang Xu's previous life, a classmate gave the teacher a sack of sweet potatoes, which he carried from Central Henan Province. It is said that everyone in the teaching and research department shared several kilograms. It tasted good and was a good talk.

"Your silk scarf is very beautiful. Did you draw it yourself? Really? This ink landscape has a bit of flavor."

"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 an ancient inheritance. I am not boasting. If you want to buy this thing, there is no place to buy it. This is not afraid of washing. You can use warm water and rub it gently to wash it. The color will not fade. "

Wang Xu casually started bragging about Professor Yan. After meeting Professor Yan a few times, he found that he was easy to deal with and didn't like crowns. It would be more in line with his temperament to speak and act more casually.

In his early years, Professor Yan went to university in the 1950s and was sent to study abroad by the government as soon as it was re-opened.

Chou Guo, his childhood days slipped away a lot, and he returned to China in the early 1980s. Looking at his habit of opening gifts, you can tell that he was developed overseas. In China these days, it would be considered rude not to open the gift right away after receiving it.

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

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

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

The first people to come into contact with Western culture and customs were wealthy families. After being passed down, some scholarly families were formed, including many in Imperial University, Shuimu, and Huake Academy.

At least in this era, the so-called scholarly atmosphere is not very serious. After all, everyone is second-rate. Don't laugh at anyone. The only way is to immerse yourself in pursuit.

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

The local doctors who were retrained after the reform have just graduated and are still too early to take up leading positions.

There are quite a lot of government-sponsored overseas students like Professor Yan who come back, and the proportion is much higher than those who later went out at their own expense. In the 1980s and 1990s, they could be said to have formed the core backbone of Chinese universities.

But then again, there was really no shortage of positions for them at that time. They were associate professors when they came back and were quickly promoted to professors. Whether it is a teaching position or an administrative position, the path is smooth.

How can it be like later, if you don’t make achievements overseas and win some awards, there will be no place to accept you when you come back, and then they scold you for being unpatriotic. Does it mean that you are patriotic when you come back to tighten screws?

Forget it, if I don’t talk about this, it would be too taboo.
