Chapter 15 Gun Carriage Power Car Semiconductor Diode

With a wave of Li Yunhe's hand, a "boom" engine sound sounded, and then a string of motorcycles, now called power cars, rushed up in this test site. It's been a long time since I've seen anything like this. The drivers showed their skills in the field, purifying the bad exhaust fumes and causing smoke to billow in the field.

Li Yunhe said: "These dozen power cars are used for experiments. I picked up two dozen nimble ones and asked them to experiment. Their daily task is to ride around. I didn't expect them to practice their driving skills like juggling.

Sure enough, more than a dozen of them raced around the field for a while, and did all kinds of stunts, one moment they landed on the ground, one moment drifted, and one moment flew over a puddle. Zhang Zhimu knew that the driving skills of those drivers in their previous life were not comparable, but it was not easy for them to make such moves with such a car.

Zhang Zhimu couldn't help but cheer for them. The riders were even more excited when they saw Zhang Zhimu waving his arms at them. Desperately put your skills to work.

Zhang Zhimu turned around and said to Li Yunhe: "Yunhe, don't disband this team, set up a special department." In the future, they can choreograph some performance movements, and if they don't do performances, they can do the test after the vehicle is produced. In the future, I can become a coach and train drivers. ”

"Okay!" Li Yunhe said, "I didn't expect that they would play with the car like this." I didn't expect the bike to ride like this. ”

"That's right!" Zhang Zhimu said, "The group for the development of power vehicles should not be disbanded. I think it's time for us to study airplanes. ”

"Airplanes?" Li Yunhe said, "It's what you said last time, the hard work theorem, the plane that can go to the sky." ”

"That's right! Bernoulli's theorem. It's an airplane! Zhang Zhimu said with certainty, "Look, birds can fly to the sky." We are so much smarter than birds, why can't we go to heaven? ”

"A bird has a pair of wings, but a man does not."

"But a man can make a pair of wings." Zhang Zhimu said, "If you have time, I'll tell you about the plane." Now what I'm concerned about is, what about your improved cars? ”

"Don't worry, those brothers who are engaged in cars are desperate, they are more anxious than you. But this time it's fast. Li Yunhe said, "There is a reason why I let them test this power car for so long." You see, this car is good now, but at the beginning, it broke down in a few days. We are constantly discovering problems and constantly improving, and we can use them now. If you don't have any opinions, I'll let them produce. ”

"I have a suggestion, you can add a sidecar with wheels next to the power car. There is also room for one person to sit in the sidecar. In this case, one more person can sit in the back seat, and a power car can seat three people. The sidecar should be made detachable, hung up when in use, and taken off when not in use. Zhang Zhimu gestured with his hand as he spoke, and gave them the shape of the sidecar.

The team leader asked, "It's okay to take it, but will it deviate to the side when driving?" ”

"There will be some impact, but it's not a big problem, and I can adapt to it quickly." Zhang Zhimu said.

"This sidecar, I'll get it when I go back." Li Yunhe said, "However, power cars should be produced and produced." ”

Back at Yaogang, Zhang Zhimu excitedly said to Yang Yulin: "You should take a look today, Li Yunhe and their power car have been very good." I'll ask Li Yunhe to get you a red powered car, it's much stronger than your red horse. ”

"I can fight on my red horse, what can I do on a power car?" Yang Yulin said.

"This power car is a good thing, you just don't eat grass and gas. Li Yunhe has already organized production, and in the future, our army can slowly realize motorization. Zhang Zhimu said.

"What?" Yang Yulin asked.

"Oops! It's all about using power cars. Zhang Zhimu couldn't explain motorization, this is another nonsense.

"You, you often babble something inexplicable."

Zhang Zhimu turned the conversation around and said, "Li Yunhe also asked, why didn't Miss Yang come today?" ”

"How did you answer Li Yunhe?" Yang Yulin asked.

I said, I don't know. Anyway, she didn't come, so I'll be cleaner. Zhang Zhimu said.

"You! It's carelessness. When Yang Yulin said this, her face flushed. This is rare.

Zhang Zhimu immediately understood, "Oops! Could it be that the young lady is happy? ”

Yang Yulin was a little shy, but nodded happily and said, "I really said it last time." I think that was the time. ”

"It seems that we can't farm in that place, so it would be nice to change places! Hehe! Zhang Zhimu was so happy, because Yang Yulin had not been in a high mood since she gave birth to her daughter. I don't know what it will be like this time.

It's really a good thing, Zhang Zhimu is in a good mood. However, thinking about Yangchang and their affairs, I hastily ate something at noon, and prepared to go to Yangchang.

Yang Yulin said: "I said, you can rest too." Otherwise, when you go, people won't be able to rest at noon, and they will accompany you. You can sleep for a while whenever you are sleepy, can someone else do it? ”

"Yes, yes! They should have been given a short break at noon. Zhang Zhimu said, "They are all desperate masters." If you have a good break at noon, you can work well in the afternoon. I also sleep for a while. ”

But at this time, Zhang Zhimu really couldn't sleep.

Now the military strength of Yaogang, I am afraid that there will be no opponents in the whole world. Not to mention economic strength. However, economically, there are still shortcomings, one is that steel has always been tight. Because building railways and shipbuilding are two major items, now building tractors is a major demand. Everything else is inseparable from steel. On the side of the smelting field, Li Dong and Liu Baoxue have already maximized their production capacity. If the Baotou Iron and Steel Plant can be put into operation, it will greatly improve the contradiction between supply and demand of steel. But that's in a year or two, and it won't work. It is still necessary to exploit the potential of the metallurgical field. However, when Li Dong came last time, he said that they were determined to push all those small blast furnaces and rebuild large blast furnaces. Two more open-hearth hearths were built. At that time, the demand for steel will be eased. Now a few small steel mills have been recovered, and the earth steel they produce can only be used for some basic civilian purposes, such as making a pot and the like. On the Hexi side, it is said that both nickel and chrome ore have been found. After they get the samples back and confirm them, they will immediately build a mine there for mining. At that time, a lot of things were easy to do, and the barrel of the gun could be plated with chrome to increase the life of the gun. It can also produce stainless steel. It was also possible to produce resistance wires from nickel-chromium alloys, and electric heating was very cheap at that time.

Another is that the demand for copper has been tight, but fortunately there is aluminum now. Li Di and the others are rearranging the high-voltage wire with aluminum wire, and once the aluminum wire is finished, the original copper wire can be removed. That's a lot of copper. In the future, the wires in the city can be replaced with aluminum. Li Mao: There has not been much progress in their purchase of Yunnan copper. This matter is not good to urge Li Mao again. Li Mao is a person who knows the importance of the matter, and he doesn't need to be urged. Later, we can study the problems he encountered, and we can mobilize all our forces to do this. No, I can't think of some other means, but I also have to solve this problem.

Then there is the matter of oil, Li Yunhe and the others have already organized people to go to the area of Shenmu to explore oil, if they can mine it, it can meet the immediate needs. But in the long run, it is not enough. A more feasible way is to extract oil from Yumen and Suzhou (Jiuquan), and now they are building roads in Ningde, but the cost of transporting them to Lanzhou by horses is not cheap. It should be decided that the Baotou steel mill will be put into operation to build a railway with the corridor, and even so. After the highway was completed, the construction of the railway began, and the roadbed was repaired first. When you have the rails, you lay the rails. The army over there can participate in the construction, as long as there is no war, the army must participate in the construction.

Thinking of that, Zhang Zhimu muttered a little in his heart. The Mongols did not have any harassing behavior in one winter, which is very unreasonable. It's a little strange that the Mongols are so honest all of a sudden. They don't move at all, and if they don't get it right, the Mongols will make a big move. They should be reminded. Our intelligence work on the Mongols is still far from sufficient, and it seems that this should be strengthened. Li Zhi and their main energy are spent in the south, and they can't give up in the north.

Thinking of this, Zhang Zhimu couldn't lie down, got up and made a call to the command center, and told Chen Yufeng about this idea.

Chen Yufeng said: "This matter, when Ningde and them came back, we discussed it. Both they and Zhou Yuji thought of this problem. They will know in their hearts. Don't worry! ”

Zhang Zhimu was very satisfied with Chen Yufeng's answer, it seems that these generals are very mature, and he is more at ease. Zhang Zhimu said: "It's good that they think of it. This morning, Li Yunhe and I went to the test site to see their power car, and I saw it very well. I've already asked Li Yunhe and them to produce power cars. I think we could set up a rapid reaction force, all of which would be mobile with powered vehicles. ”

"Good! We also have time to look at the power car you mentioned. Chen Yufeng said.

When he came to Yangchang, as soon as Yangchang saw Zhang Zhimu, he said: "Mr. Zhang, it's just great!" Our diodes are made. This thing is simply amazing. "Yangchang and Zhang Zhimu are already very familiar, and now they talk casually, without so many kind words.

Zhang Zhimu pulled over a chair by himself, sat down and said, "Tell me about your diode." ”

"That's right, we and Qingfengzi's disciples have done more than hundreds of experiments. The pulse current we used for that thing was too big, and the wire burned out. If the current is small, it will not work, and the sintering will not be successful. Burned out a lot of cut crystals. They were distressed. Master Qingfengzi said, that thing is more expensive than gold! Hehe! We can't help it, and we feel distressed, but we have no other way but experiments. Even if it is sintered, it is not all easy to use. Finally, when we tested the voltammetry characteristics, it burned out a lot. This thing can only pass a dozen milliamps of current. But it's enough for detection. Yesterday we plugged this rice-sized diode, instead of an electronic diode, and connected it to the radio, and all of a sudden, we received the sound. We almost cried. This thing is simply amazing. Just the size of a grain of rice, it can replace an electron diode as thick as a finger. The amount of energy consumed is negligible. In the future, if we make a triode and replace the triode, will the energy consumption be smaller? Yang Chang became more and more excited the more he talked.

Zhang Zhimu said: "Let's go, let's see your baby!" ”

"Good!" Yang Chang said, leading Zhang Zhimu to another room.

As soon as he entered the house, Zhang Zhimu saw a group of people listening to the radio together.

Hearing the door, these people looked back and saw that it was Zhang Zhimu and Yangchang who had come in, so they all dispersed and gathered around. Talking nonsense, he said: "Mr. Zhang, come and listen, what's the difference between a radio made of semiconductor diodes?" ”

"Mr. Zhang, this thing saves space and electricity, and the circuit is much simpler."

Listening to the sound coming from the radio, Zhang Zhimu said: "If you don't say that it is a radio with diodes as detectors, I can't hear it with sound." I congratulate you on your success. ”

However, Zhang Zhimu saw that the diodes they tested were not encapsulated, and they were exposed. "You have to seal the diodes with glass and test their life," he said. You have to remember that all products, especially electronics, have a failure curve that sprays. Because if they have defects, they will be exposed at the beginning of use, and if there is no problem, they will enter a long period of stable use. Later in life, they will fail again. That's why our electronics need to age. ”

Yang Chang said: "Okay, let's produce some more, and after the packaging is finished, we will carry out aging experiments together." Test their longevity. ”

"The next step, you are facing a bigger hurdle, the production of surface contact diodes, and then you can produce triodes." Zhang Zhimu said, "However, now this kind of point-contact diode can be organized for production." ”

"But now the yield is too low!" Yang Chang said embarrassedly.

"You can't use manual methods, you must develop new production equipment, combined with strict technology." Zhang Zhimu said, "You call Li Yunhe immediately and ask him to come over." ”

After a while, Li Yunhe rushed over, and shouted when he entered the house, "I said Mr. Zhang, you can't do without me for a while, you just broke up in the morning!" ”

"It's nonsense, look at the good things they did in Yangchang." Zhang Zhimu said.

Yang Chang introduced semiconductor diodes to Li Yunhe again, and Li Yunhe picked up a diode the size of a grain of rice and said: "Such a small thing, if you can't hold it on both legs, it can replace an electronic diode, it's just amazing." ”

Li Yunhe put down the diode and asked, "Mr. Zhang, what do you mean?" ”

"Yunhe, you see this mysterious thing. However, the finished product is now too low to be produced by hand. It is necessary to replace the manual work with equipment. Zhang Zhimu said.

"You mean, let's organize people to build equipment for the production of secondary pipes, don't you?" Li Yunhe immediately understood what Zhang Zhimu meant.

Zhang Zhimu said: "Yes, but your people must cooperate with Yangchang and Master Qingfengzi's people." This is where precision machinery is needed. ”

"Good! I'll arrange for a few good hands right away. There are a few people who have always felt that their skills are not small, and this time they are given a difficult problem and let them tackle it. Li Yunhe knew that this matter was not simple.

Before leaving, Zhang Zhimu said to Yangchang and them: "You below should break through the surface contact diode as soon as possible." At that time, we will celebrate together. However, this time the meritorious personnel will be rewarded. You also bring everyone to celebrate well. ”

"Good! You can rest assured Mr. Zhang. Yang Chang said.

As soon as he left Yangchang and them, Li Yunhe asked, "Mr. Zhang, do you want to do a private matter?" ”

"Hey! What are you doing with me? Say it. Zhang Zhimu feigned anger.

"That's right, can you talk to Xiao Hongyu, can you help me get a few movie tickets? My family had to make a fuss about me trying to figure it out. Li Yunhe said embarrassedly.

"That "Tang Guifei" is about to be released?" Zhang Zhimu suddenly understood.

"Yes! Advance tickets are being issued. I guess the queue will squeeze people to death. Li Yunhe said.

Originally, Zhang Zhimu didn't want to care about this kind of thing, but Li Yunhe's matter couldn't be ignored. Say, "Come with me to the office!" ”

As soon as he entered the house, Zhang Zhimu said to Yang Yulin: "Give Xiao Hongyu a call!" ”

Yang Yulin hurriedly asked: "Is it a matter of movie tickets?" Don't forget to get a few more. ”

Listening to Yang Yulin's words, Zhang Zhimu was even more embarrassed, he knew that Xiao Hongyu would be under a lot of pressure now, and it would be difficult for her to refuse the person who found her.

Li Yunhe saw Zhang Zhimu's demeanor, regretted it a little, and said, "Mr. Zhang, I don't think it's going to fight." If you make a start, you can't help it. ”

Zhang Zhimu didn't speak, Xiao Hongyu's phone answered, and Zhang Zhimu just asked, "Little Hongyu?" ”

On the phone, Xiao Hongyu said, "What? Are you also a matter of movie tickets? ”

"No, no, how could I embarrass you at this time. That's the case, you have to arrange a special session for the families of our cadres in the kiln gang, and hold a special special session. In this way, whoever asks for you, you can say that it is my request, and all the tickets that are sold to the outside must be sold from the front window. Buy a ticket and sell up to two tickets at a time per person. When selling tickets, let the police maintain order. We can make it public on the radio and in the newspapers. Zhang Zhimu said.

"Great, otherwise I'd be dead dead." Xiao Hongyu said, "I don't even dare to answer the phone." Who I can afford to offend? It's good now. ”

Yang Yulin, who was next to her, smiled and said, "Hehe! You're so distressed! ”

Li Yunhe also smiled and said, "Miss Yang, don't forget to leave me a few more tickets, there are many people in my family." He knew that Yang Yulin must be in charge of such a thing as an internal **.

"What do you call me?" Yang Yulin asked Li Yunhe.

"Yang," Li Yunhe quickly changed his words, "Sister-in-law, sister-in-law!" ”

"I haven't said anything about you, why am I not qualified to be your sister-in-law? I also want movie tickets. "Yang Yulin is energetic.

"Qualified!" Li Yunhe said: "Oops! It's not like it's used to it, and it can't be changed all at once. ”

"You can't change it all at once, my children are so old, you can't change it." Yang Yulin deliberately refused to give up, because Li Yunhe needed the movie ticket in her hand.

Zhang Zhimu hurriedly relieved Li Yunhe and said, "I said you got it!" Don't look at Yunhe as honest, you will be bullied endlessly. ”

"Huh!" Yang Yulin laughed and said: "Who said that Li Yunhe is honest, he is very bullish outside, and he is a person who doesn't pay attention to anyone except Mr. Zhang." If I hadn't had a movie ticket in my hand today, how could he be so obedient? Hehe! ”

"Huh!" Li Yunhe pretended to smile bitterly and said, "Sister-in-law! When did I dare not listen to you? ”

"Hmmm! That's pretty much it? Yang Yulin was satisfied, "Say, how many people are in your family?" ”
