Siheyuan: Starting from a fitter

Chapter 72 Discussing Computers

The matter was decided by the old man forcefully. Mother Zhao is still emotional, so Father Zhao needs to explain and comfort her.Zhao Ting also had many questions, so she pulled Li Guocheng into the guest room.

"What's going on? Why did grandpa just make the decision without any warning before?"Zhao Ting asked eagerly as soon as she entered the guest room.

Li Guocheng briefly explained the situation in the study. He did not expect that the old man would be so interested in machine tools, so he fell in love with the house and everything, and successfully got the old man's approval.

"What about my dad's opinion?"

Zhao Ting became worried about gains and losses. She didn't want to have a dispute with her parents before, so she used work as an excuse to hide out.

"Your father shouldn't object." Although he didn't object, Li Guocheng also felt Zhao's father's rejection and suspicion of himself. However, the old man was very strong, so he did not express his position clearly.It was useless to express his feelings at this time, and it would make Zhao Ting worry in vain.

Finally letting go of the burden of family opposition, Zhao Ting began to worry about herself.

"I'm so ugly, are you really willing to marry me?" Zhao Ting touched the scar on her face. She had no hope before. She deceived herself and others, and just muddle along. She didn't dislike Li Guocheng. As long as the other party was willing, she could just let it go.After receiving support from the old man today, she began to think seriously about the future.

Li Guocheng stepped forward to hug her and kissed his scar.

"This is the medal you paid for the country. I have only admiration and admiration." Li Guocheng looked into her eyes affectionately.

Li Guocheng was about to make further moves when Zhao Ting blocked his mouth with her little hand.

Hearing Li Guocheng's answer, Zhao Ting was very moved, but there was still a knot that had to be untied. After all, the two of them would really live together.

"I want to make one thing clear to you again. My current job is very busy and may be dangerous. Are you still willing?"

"How many times have you asked me, Li Guocheng once again solemnly declares that when you go on a mission, I will wait for you at home. If there is danger, I will fight with you."

Although Zhao Ting had heard similar answers many times, she felt even more moved today.She hesitated, put down her hand, and slowly closed her eyes.

Li Guocheng still hesitated and kissed her directly.

After an unknown amount of time, Zhao Ting, who was flushed, pushed Li Guocheng away and habitually kicked Li Guocheng's calf with her toes. She was so embarrassed that she wanted to throw him over her shoulder.

Li Guocheng made a show of provoking war again, and Zhao Ting, who had regained her senses a little, hurriedly stopped it.

"Grandpa, grandma, mom and dad are all downstairs!"

Li Guocheng also gave up when he saw good things. He knew that Zhao Ting had a fierce temper and was thin-skinned, so he didn't dare to push too hard.

After repeatedly promising not to cause trouble, Zhao Ting was reluctantly carried into Li Guocheng's lap.

"I'll give you a big gift in a few days," Li Guocheng said mysteriously.

After lunch, the three men came to the study again.

"You mentioned semiconductors this morning, and you have mentioned them many times in recent meetings. Tell me your views." The old man took over the topic again.

"In some translated magazines, there were prospects for computer applications, believing that computers will enter all walks of life in the future, and whoever masters computer technology will take the lead."

"Today's computers are too large, consume a lot of power, and are difficult to popularize." Zhao's father knew the domestic computer technology at a glance.

What Dad Zhao mentioned should be that in 1959, China imitated the Soviet Union's БЭCM-Ⅱ computer and developed the 104 computer, which could barely reach 1 times. However, because it assembled 4200 electron tubes and 4000 diodes, covering an area of ​​more than 400 square meters, the electron tubes often Damage, low reliability.

After the 104 aircraft was delivered to the aerospace and military industry departments, it completed a number of scientific research calculations for a number of major projects.

Although the performance of the 104 machine is still far behind that of Chouguo's RCA501 computer, it is almost the same as that of Yingguo, RB and other computers that started in the same period.

"Yes, the current computers are indeed huge, but the emergence of transistors can greatly reduce the size of computers, greatly reduce power consumption, and improve reliability and synchronization by several orders of magnitude."

Li Guocheng saw that the two of them were interested in computers, organized language, and wanted to influence them, so that the upper management would pay attention to computers and avoid continuous lagging behind in future generations. At the worst, he could use their support to form a team to continue researching semiconductors.

"If I remember correctly, the 109B computer is a transistor computer. The investment is too high and it is only used for key national defense projects. It is too difficult to popularize it. Our country is still too poor and has little foreign exchange. The most important thing now is to solve the national economy and people's livelihood problems. Now We've run out of computers to keep going."

Father Zhao did not look down on Li Guocheng. After all, the 109 B machine was still in the testing stage and was not accessible to ordinary people.Since he was forced to make a decision by the old man, Father Zhao just used these non-confidential contents to hit him.

He didn't expect that Zhao's father had such a deep understanding of computers. Li Guocheng thought that China would not continue to study computers at this stage, but he knew history. From now on, China's computer technology has begun to widen the gap with foreign countries, and it is getting bigger and bigger.

When I was in college, I seemed to have heard from my teacher that Huaxia’s scientific research and technology in this era mainly serve national defense science and technology. Only large investments did not produce social and economic benefits. The burden became heavier and heavier, so the investment was reduced year by year.

Thinking of this, Li Guocheng became even more excited. Now that there are transistor computers in the country, as long as they can be persuaded and their support is obtained, chip research and development can continue.

"We can change our thinking. Now the country only invests in computer research and development, but there is no economic return. If we use computers for civilian use, improve production efficiency, and improve the technological content of products, this will produce direct economic benefits. If the products are excellent , and you can also earn foreign exchange.”

"That's impossible. Today's computers are too expensive and too delicate. You can do scientific research and calculations, but don't think about anything else."

Father Zhao and the others have held many meetings to discuss computer applications, but in the end there was no good solution but to reduce investment.

"What if the computer is integrated into a module?" Li Guocheng proposed the concept of future microcontrollers ten years in advance.

"How is this possible?!".

"It's completely feasible. The main reason why today's computers are huge and have low reliability is that the transistors are discrete, and they are connected by lines, which are prone to contamination and damage.

In the three-by-three system of our army, the smallest combat unit is a squad. Three squads form a platoon, and three platoons form a company. The company forms a regiment, a brigade, a division, and an army, until a military region is formed.If the functions of the computer are broken down into small modules, each module completes a function, and the small modules form large modules until a computer is formed.

Dozens or hundreds of transistors are simultaneously prepared on a wafer used to produce transistors. They are connected with metal wires to complete one or more minimum functions, and then packaged with ceramics or plastics. Will the volume be reduced a lot and the resistance to The pollution capacity has also been increased.

As the technology matures, it is possible to integrate all these functions into a large module, which is only as big as a cigarette box or a matchbox, and can be used for people's livelihood, such as automatic control of machine tools."

Li Guocheng directly talked about it, and the two of them thought about it and it seemed that it could be realized, and they gradually became excited.
