Scholars in the courtyard

Seventh Machinery Department, computer research base.

Yang Xiaotao was brought in after contacting Han Sanfeng.

Yang Xiaotao looked at the situation on the left and right along the way and compared it with the scene he saw last time he came here.

It can be seen that there are many more machines than before, and there are many more people.

And many of the people here have young faces.

They must be newly recruited college students.

Yang Xiaotao was also thinking about whether he should mention it to Mr. Chen to give the machinery factory more places for college students. If that didn't work, high school students would be fine.

Following the staff to the underground, it was the same place as last time. Yang Xiaotao saw Han Sanfeng.

"Uncle Han, long time no see."

Han Sanfeng in front of him was a little unshaven, and it looked like he hadn't taken care of his personal hygiene for a long time.

Not just him, but everyone else working here is similar.

The female workers are better and know how to take care of their hair. As for the men, they probably just wash their faces.

Of course, in this environment, Yang Xiaotao's first impression was a job with great potential in his previous life.

Programmer!

Well, speaking of it, these people can be considered the first generation of programmers.

"Long time no see, are you here this time?"

Han Sanfeng felt a little uneasy when he saw Yang Xiaotao's head.

There was no way. Some of the things that the Machinery Factory sent to the Seventh Machinery Department were cut off by Mr. Wang. He knew what they did, but he couldn't tell.

The remaining part was subsidized by him into computer research. After all, we are all one family.

You can't create a gap or create a confrontation.

Therefore, there is no way around this.

But now that I see this person’s ‘employer’, I feel a little guilty.

"Uncle Han, didn't I go to Jinling? When I got back, I just came over to see how the calculator research is progressing."

Yang Xiaotao said the purpose and Han Sanfeng nodded.

"Wang Kun and the others are down there. I'll have someone find them for you."

"Okay, that's troublesome!"

Han Sanfeng shook his head and asked the staff at the door to find someone.

Yang Xiaotao started chatting with Han Sanfeng from the side.

Of course, what the two talked about most was computers.

Han Sanfeng and the others have already started researching integrated circuits, but this technology requires investment support from many aspects. When he said this, he couldn't help but glance at Yang Xiaotao.

If the machinery factory gives full support, he is confident that he will achieve a breakthrough within three years.

Unfortunately, this is just a thought.

"By the way, Uncle Han, how far have computers developed abroad?"

Yang Xiaotao suddenly became curious.

It seems that the development abroad is very rapid.

It seems like Little Apple hasn’t appeared yet.

The United States has only just entered the research into integrated circuits. It will probably take more than ten years to wait for ultra-large-scale use.

Yang Xiaotao was thinking about something, but Han Sanfeng found a document from the pile of documents on the side and handed it to Yang Xiaotao.

"This thing is top secret abroad, and we don't know much about it."

"This information was obtained from newspapers."

Yang Xiaotao took a look and found that they were indeed cut-out newspapers, and they were all in English.

Fortunately, Yang Xiaotao's English has been systematically strengthened, so he can understand it clearly.

"It seems they are developing very fast."

"Integrated circuits have been announced. It is estimated that the actual research will be faster than reported."

Han Sanfeng nodded. Considering the thinking of Chinese people, he must be hiding good things. What he announced is outdated.

That's why Han Sanfeng felt an inexplicable sense of urgency.

"And this."

Han Sanfeng took out another document. After Yang Xiaotao took it, he found that this document was much thicker than the previous one.

After opening it, I found that it was not in English, but in Alliance language.

"This is the research situation on the league's side."

With that said, Yang Xiaotao opened it.

I saw that the information here is relatively complete, and it also introduces a computer called "Arrow".

The entire computer is composed of more than 6,000 vacuum tubes and more than 60,000 semiconductor diodes, and can operate up to 3,000 times per second.

Looking at the data in front of him, Yang Xiaotao raised his head and asked in surprise, "Three thousand times per second, can we do it?"

Han Sanfeng shook his head.

"Our earliest one was only 30 times per second. Now after years of development, it has reached the level of 8,000 times per second."

"However, this computer is a product of the alliance ten years ago."

"Ten years ago, the difference was a hundred times. Now, I don't know how much the difference is."

Han Sanfeng said a little decadently, but Yang Xiaotao laughed.

"It's hard to say, what if someone is lazy?"

"It's like a little cat fishing, fishing for a while and playing for a while, doesn't it just give us a chance to surpass it?"

Han Sanfeng burst out laughing after hearing this, "Then I'll lend you some good advice."

Yang Xiaotao smiled, "What I say is usually accurate."

"As long as we develop integrated circuits and succeed, we may be able to overtake others in a corner."

Han Sanfeng nodded, "This is what I want to do too."

The two chatted for a while, then there was a knock on the door, and then they saw Wang Kun and Liu Yongqiang walking in.

"director."

"Mr. Yang!"

The two said hello and then came up to see each other.

"Okay, you guys can talk among yourselves, I'll get busy first."

Han Sanfeng stood up and left the office to the three of them.

After Yang Xiaotao waited for Han Sanfeng to leave, he started chatting with the two of them.

"Have you received the Mid-Autumn mooncakes?"

Leaning on the table, Yang Xiaotao asked the two of them to sit down, then took out a cigarette and put it on the table.

Although smoking is not allowed here, it does not prevent two people from carrying it.

What's more, in this environment, there is a lot of pressure.

Going back to your residence and having a smoke with your colleagues can relieve your nervousness and bring you closer to each other.

"I got it, Wuren's and Bingtang's, each weighing half a catty."

"It's so big, all the comrades here are envious of it."

Wang Kun smiled and Liu Yongqiang nodded, "We all took it out and divided it with our comrades."

"If you divide it, divide it. If you eat alone, you will get beaten easily."

Yang Xiaotao smiled, and the two of them also laughed.

Although most of them were given away, what they got in return was a look of envy.

Some people even asked if this calculator research institute still needs people. They also want to get a "part-time job".

Naturally, the two of them did not dare to agree. After all, they were just working for others.

After talking about the matter, Yang Xiaotao thought about it and shook his head to refuse. After all, this was on someone else's territory, and poaching would not be a good idea.

"By the way, Mr. Yang, we have done a lot of investigations during this period."

Wang Kun began to report on his research work, and Yang Xiaotao cheered up to listen.

"There are some classmates of mine at the Shanghai Computer Research Institute. I heard them say that their display screen has been made, but it is only used on computers. I think I can contact them."

Wang Kun explained the situation, and Yang Xiaotao realized that there was more than one such computer research center in the country.

It is not only available in the Seventh Ministry of Machinery, but also in some universities and research institutes.

It seems that the first calculator of later generations was made in Shanghai.

"You write a report on this matter, and I'll ask someone from the machine factory to contact you later."

"good."

Wang Kun looked excited. If the display screen is solved, with their research capabilities, the circuit setting is not a problem.

If all goes well, the prototype will be ready for inspection next year.

In this way, they can be regarded as living up to the heavy investment of the machinery factory and worthy of Mr. Yang's respect.

Then the two talked about some ideas about the calculator, and also explained some operating principles to Yang Xiaotao.

In this regard, Yang Xiaotao could only cover his forehead and record it bluntly.

God knows how difficult these math problems are.

He would rather make an eighth-level component than waste so many brain cells.

"I have one more thing to do this time."

Just when Liu Yongqiang was about to take out a pen and paper to demonstrate to Yang Xiaotao, Yang Xiaotao quickly interrupted and said.

Colleague, take out a piece of paper from your backpack.

When the two of them took a look, they immediately understood what they were going to do.

Then came a burst of excitement.

Because this matter is too simple for the two of them.

Isn't it just to calculate the possible composition of metals?

A piece of cake.

And the rewards are huge.

Because they helped last time, I heard that alloy materials were made, so I gave them a lot of rewards.

If they can do it this time, based on their understanding of Yang Xiaotao, they will definitely be rewarded a lot.

"This is a piece of data I got from the Aviation Academy when I was on a business trip to Jinling."

"It should be similar to the titanium alloy last time, but it has an additional material called rhenium, which should be a main material."

Please help me and see if you can help me figure it out.

"no problem."

Wang Kun immediately assured, "I know about the metal rhenium. When I was studying in university, my teacher studied metals, and the research on rhenium was the main topic."

After hearing this, Yang Xiaotao immediately became interested, "Really? Let's talk about it."

Liu Yongqiang on the side took the paper and walked to the next door and started calculating.

Wang Kun then thought for a moment and said, "We all know that parts made of pure metal have many problems, such as rust, insufficient toughness and easy brittleness, insufficient strength and easy breakage. Problems such as these lead to the emergence of alloys. This material."

"Rhenium is a very useful metal 'additive'. My teacher said that this metal has good plasticity and can be processed into various structural materials. It also maintains high hardness, high strength and high temperature resistance. and other characteristics.”

"Yeah?"

Yang Xiaotao was a little excited. If this was true, then this alloy material would really have to be made.

Then I thought that this thing was taken from a burned-out helicopter, and it was from the United States. I can be sure that this rhenium alloy is definitely a good thing.

Wang Kun just scratched his head when he heard Yang Xiaotao's question, "This is what my teacher said."

"Where's your teacher?"

Yang Xiaotao quickly asked whether such a talent would be the most suitable for their machinery factory.

But after Wang Kun heard this, he looked a little depressed, "Teacher, because, because of some problems, I couldn't bear the pressure, so I chose."

Yang Xiaotao let out a long breath after hearing this. There are so many such things.

"What a pity!"

Wang Kun nodded, and then returned to the previous topic, "My teacher also said that the future development prospects of this metal rhenium are very good. However, the price is a bit expensive. When he was doing research, there were only 20 people in the entire school. Gram or so."

“Back then, it was just a matter of using a little and then a little less.”

"Are there few things like rhenium?"

Yang Xiaotao suddenly realized a problem.

Although China is vast and rich in resources, there are also scarce things.

"Few, very few."

Wang Kun said seriously, "My teacher said that most of these metal rhenium are now monopolized by the Alliance and the United States."

"If we want to get these, we have to import them."

"The 20 grams of rhenium in the college were given by the professors and tutors of the school when the teachers went abroad to study. As for after returning to China, the teacher asked around, but he didn't hear that there are rhenium mines in our country."

"As for metal smelting"

Wang Kun didn't say much. Yang Xiaotao also understood the situation of domestic smelting. Let alone smelting rhenium, even making tungsten metal is a big challenge.

"It seems that we really have to think of a way to get this rhenium."

Yang Xiaotao did not give up the research on rhenium alloy.

Since it is useful, it means that it is necessary to exist.

We can't wait for everything to happen later.

As for raw materials, Yang Xiaotao suddenly remembered a sentence in "Das Kapital", 'Once there is a proper profit, capital will be bold. If there is a 10% profit, it is guaranteed to be used everywhere. If there is a 300% profit, it will dare to commit any crime, even at the risk of being hanged. ’

With money paving the way, even if it is to control materials, there will always be people who take risks.
