Wang Xuexin's estimate was correct. Even though Wang Xuexin had told Qiong the solution, a transport plane that never set still landed at Liyuan Airport two days later.
This time there was no need to keep it secret. Boxes of parts including wires, generators, relays and even electronic tubes were moved to the warehouse prepared by Wang Xuexin.
The generator is because the Eighth Route Army's generator was modified from a car generator. The voltage it provides is unstable, sometimes high and sometimes low, and sometimes it suddenly stalls and cuts off the power. Such a generator is fine for mechanical computers... "Christopher"
It has built-in storage capacity, so even if there is a power outage, it will not have much impact.
But the relay computer is not good. It has high voltage stability requirements. Otherwise, even if there is a paper tape dot method to store data, there will still be a situation where a relay is damaged and affects the entire machine.
Thirty thousand relays were shipped in one go.
Wang Xuexin estimated that 13,000 were needed, which was based on the requirements of the Mark 2 computer... It used 13,000 relays. It is said that one summer in 1947, a moth flew into the Mark 2 computer and caused one of the relays to burn out, resulting in the machine being damaged.
If it fails and cannot work, this is a famous BUG incident in history.
From then on, software defects or loopholes were all expressed as BUG.
Vacuum tubes were requested by Wang Xuexin, because they have already been used in relay computers, but only in small quantities.
Wang Xuexin is more interested in electronic tubes than relays.
Because he clearly knows that computers using electron tubes can be a thousand times faster, and have various advantages such as small size, low failure rate, and low power consumption, so why should he target relays?
The reason why Wang Xuexin is willing to play with these relays now is just to show them to the sun.
But that's not entirely the case.
Because Wang Xuexin believes that the Eighth Route Army should also cultivate its own talents in this area... Qiong, a man who never sets on the sun, will eventually go back after completing their project and will not be used by China. Wang Xuexin may be a qualified participant, but the problem is that he
There are still battles to be directed, and it is impossible to stay in the laboratory for a long time, so it is necessary to involve your own team and let them grow in the process of cooperation with Qiong and his team.
In fact, this is not only true for computers, but also for radars, car engines, aircraft, etc.
Wang Xuexin did not need to think about talents. Wang Xuexin only had to send a telegram to Su Xin, and Su Xin immediately went to search for talents and sent them to Liyuan as soon as possible.
What Wang Xuexin wanted from Su Xin was to be familiar with electronic tubes and plus two talents in mathematics.
This is a kind of helplessness, because there was no "computer" industry at this time, so it was impossible to find computer talents.
Fortunately, Wang Xuexin knew that computers were developing in the direction of electronic tubes in terms of hardware, and that the end of software development was mathematics, so he looked for talents in these two areas.
To Wang Xuexin's surprise, there were still a lot of talents in the field of electronic tubes. Su Xin sent over a dozen, but there were only two people who were interested in mathematics. Among them, the hardware was sent as a talent in the field of electronic tubes.
Already.
Later, Wang Xuexin learned that vacuum tubes had been widely used in radios, amplifiers, gramophones, radio stations, and radars during this period. However, Wang Xuexin had no research on these things at all, so he had no idea.
Hardware was overjoyed to see Wang Xuexin. He held Wang Xuexin's hand and laughed and said, "Comrade Wang Xuexin, as soon as I heard from Director Su that you want someone who can use electronic tubes, I signed up right away!"
"Can you use it?" Wang Xuexin asked.
"Isn't that right?" Hardware replied confidently: "Those of us who work in hardware stores, who hasn't repaired gadgets like radios? I've seen a lot of things like vacuum tubes!"
Wang Xuexin said "Oh" quite disappointed. It seems that China's talents in electronic tubes are probably limited to the level of hardware!
This is not possible. They just know how to use it, but they don't know how to produce it. In the end, they will still be stuck by others.
Wang Xuexin frowned and asked: "Hardware, can we produce electronic tubes? Or is it possible to produce electronic tubes?"
Hardware thought for a while, then shook his head and said: "At least now, I don't know that we can produce this thing! Shanghai can indeed produce radios, but key parts such as tubes, capacitors, detectors, etc. are all shipped in from outside.
The casing and connectors are produced by our local workshop in Shanghai, and then as soon as they are assembled... the radio comes out!"
The hardware industry is in the Shanghai factory, so we know these things very well.
Seeing Wang Xuexin's frown, Hardware thought for a while and said: "Captain, if you want to produce electronic tubes by yourself, I think you should find someone!"
"Who?" Wang Xuexin asked.
At this time, he had given up hope. After all, this was China where industry had just started. If there were no electronic tube factories even in a place like Shanghai where concessions were everywhere, then everything would be gone.
"This man's surname is Su, and his name is Su Liguo!" Wu Jin said: "His grandfather was once a business leader in Shanghai, and everyone in Shanghai knew about it. Later, when he came to Su Liguo, his family fell into disgrace. He just managed to accomplish something at Yingjiang.
...I’m not sure about the school. I heard that I majored in radio.
!This guy was obsessed with radios. He tinkered with everything all day long. When he had no money, he assembled his own radios and sold them. Later, he opened a small factory in Shanghai. I heard that they could produce capacitors and resistors by themselves, so
The radios we sell are much cheaper than others, but this tube is... not sure!"
When Wang Xuexin heard this, he became interested: Yingjiang has returned from studying abroad and is majoring in radio. The most important thing is that he has a strong interest in this and can produce some parts by himself. He should have something on hand.
"Where is he now?" Wang Xuexin asked: "Is it possible to find him?"
"After the fall of Shanghai, the Japanese took over his small factory!" Wu Jin said: "It is said that they wanted to arrest him to help the Japanese produce radios. He escaped overnight. I don't know where he is! As for whether he can be found..."
Speaking of hardware, he smiled "hehe": "We in the Eighth Route Army have no other skills, but we are good at finding people!"
When Wang Xuexin heard this, he thought so too.
The intelligence personnel of the Eighth Route Army can be said to be all over the world, and all kinds of information cannot escape their eyes. I didn't know this person until I didn't look for it before. If I really find him now... Unless he died somewhere in the chaos of the war, otherwise
Nine times out of ten, you can find it.
Thinking of this, Wang Xuexin nodded and said: "We must find this Su Liguo, we are in urgent need of such talents!"
