Chapter 43 High-Voltage Transmission Engaging in electron tubes

The construction of this circle building department store took Lu Chengxiang a lot of energy, from the design to the construction process, I don't know how many modifications were carried out before it was finally completed.

It took a lot of effort to renovate the mall.

But when Zhang Zhimu entered the mall, he saw that the roof of the shed that had been installed was already installed, and there were workers who seemed to be doing drilling and other work.

Zhang Zhimu asked, "Mr. Lu, why do you have to repair it again before you use it?" ”

"No, that's the case, I asked Li Di and them to come over and install a few electric exhaust fans, after they came, they saw that there were oil lamps all over the walls of our mall, they said, these oil lamps are a little, and soon the walls and the roof will be blackened, it's a pity that such a good thing." Later, they said that they should get us some electric lights like the one on the school side as soon as possible, and fortunately, when the building was built, the wires were all laid out, and we would peel off the wires and expose them, and wait for them to come and install the electric lights. Lu Chengxiang said.

Zhang Zhimu said: "It would be great if our mall could use electric lights, because we have too many customers coming and going from the kiln. Several of our inns are almost full, so you can close a little later, and customers can come and shop in the evening. However, I looked at the electric lights in the school and found that there was another problem, that is, they all used a wire to hang each electric light, not to mention that it was not beautiful, and the upward radiation light was wasted. ”

Chen Yufeng couldn't help but say next to him: "It's great to have electric lights, not only is it bright, but there is no smoke yet." ”

Zhang Zhimu said while following Lu Chengxiang everywhere: "I don't have time, if I have time, I will make a fluorescent lamp that glows white." At that point, the light will be better and the electricity will be saved. ”

Chen Yufeng said: "Come on, Zhimu." Don't get distracted by other lights. You'd better get that tube out, if that thing comes out, we'll be able to get in touch with anywhere, and it'll be much easier to start a war. ”

Zhang Zhimu hurriedly said: "Okay! I'm going to go back and don't get anything, just the tube. ”

Lu Chengxiang really has a set of business, he turned the first floor into a stall area for grain, live poultry and non-staple food and large hardware commodities; On the second floor, there are all kinds of general merchandise, clothing, silk cloth, cotton yarn, and all kinds of goods from the north and south. There are many things in the mall, Zhang Zhimu and Chen Yufeng have never seen; On the third floor, there are jewelry, ornaments, gold and silver handicrafts and spices and other rare treasures, and the latest clocks and watches produced by Yaogang are also placed here; The fourth floor is the office and wholesale business area; The fifth floor is not used yet; The space enclosed by the circle building happens to be the freight yard.

The management of the shopping mall adheres to the rigorous and meticulous style of Shanxi people, each counter has a counter manager, each stall area has a stall leader, each floor has a shopkeeper, and the whole shopping mall has two shopkeepers and three shopkeepers of the big shopkeeper. Purchasing and shopping malls are separated, and Lu Chengxiang has designated a special person to go out to buy. Of course, Lu Chengxiang will organize the purchase and the various units of the shopping mall to discuss what sells well and what sells badly, and then determine the purchase plan.

Another feature is that the goods produced by the kiln are placed separately from the purchased goods.

What is refreshing is that for the first time, the salespeople in the department store have women, and those women's goods and cloth stalls have male and female salesmen. This is also rare in the Ming Dynasty.

The costumes of the service staff are uniformly tailor-made, and the male salesman and the counter manager are generally gray cloth clothes and pants, and the stall leader is brown clothes and pants. In order to show the identity of the shopkeeper on the floor, he is always dressed in satin.

These personnel are rigorously trained from top to bottom.

After looking at the mall, Zhang Zhimu said: "Mr. Lu, our Yaogang Department Store should be the largest store in the entire Ming Dynasty, right?" ”

Lu Chengxiang said: "I don't know if it's the biggest, anyway, we are also going from south to north, and we haven't seen a place that can compare with us until now." Everything we can think of, it's all here, from needles and threads to glass carriages. When you enter the mall, you can not only buy things, but also snacks from the north and south, as long as you have money and don't have to go out of the mall, you can eat to your heart's content. ”

Chen Yufeng said: "I said, Mr. Lu, are you a little too dark. The environment in your restaurant is good, but the things are too expensive. Who can come to eat such an expensive thing, we Shanxi people will settle accounts, don't we know?"

Lu Chengxiang smiled and said, "Mr. Chen, you don't know, do you think this is for ordinary people to eat?" Those who can eat here have status. Those who have a little bit of money may be calculating elsewhere, but they will never be counted here, don't you see that our restaurant is surrounded by glass? That's what makes the rich show their faces here. Being able to eat a meal here is a very status, and after they finish eating, they will not only say that the food is worth it, but also go around saying that the food is good. ”

Zhang Zhimu smiled and said: "Mr. Lu understands the mentality of those rich people too clearly. It's to give them a chance to show their faces and show their wealth. ”

"That's right, what an honor it is for those young masters to invite someone to have a meal here. Shall we help them! Mr. Lu's smiling face became even more garden.

Zhang Zhimu has to admire people like Lu Chengxiang, he has never run a large shopping mall, but he can't find a loophole in management now. This is related to the experience accumulated by Shanxi people in business for a long time, and the shopkeeper and stall manager he hired have all had business experience, and what they summarized together should not be wrong.

"When will it open? It's the New Year soon. Zhang Zhimu asked.

Lu Chengxiang said: "Oh, just wait for the electric lights to be installed, otherwise everything will be ready." Don't you see that the merchants in Shanxi and even all over the country who cooperate with us are almost crowded with our inns. The merchant who came from Qingxu, we got a special counter for them, specifically to sell them old vinegar, and their owner and shopkeeper have long been waiting for the opening. ”

Zhang Zhimu has eaten Qingxu's real old vinegar, which is incomparable to the old vinegar sold in his previous life. The real aged vinegar must really go through the summer exposure and winter ice fishing, and then the essence of aging is the old vinegar. In fact, Zhang Zhimu knows that whether it is summer exposure or winter ice fishing, it is to remove water and concentrate the vinegar. That's why there is such a fragrant old vinegar.

After looking at the mall, Zhang Zhimu thought to himself that this time he would have to squeeze out time to engage in an electron tube, with an electron tube, it would be easy to do a lot of things, and his radio major could be useful.

As soon as he entered the office, Zhang Zhimu saw Xiaohu talking to Song Jiaxin. But seeing that Zhang Zhimu's smiling little tiger pouted, Zhang Zhimu hurried over and said, "What's the matter, who dared to bully Xiaohu." ”

Xiaohu was aggrieved and wanted to cry, Zhang Zhimu hurriedly took Xiaohu into the inner room and said, "Xiaohu is a man, a man can't cry." ”

Xiaohu said, "Uncle, you haven't played with me for a long time." Saying that, Xiaohu was a little tearful.

Zhang Zhimu knew that he hadn't had a good time with Xiaoqing and Xiaohu for a long time. Zhang Zhimu said: "Look, I don't have time, so you just come to us to play?" ”

"Mom won't let me come and disturb you. I'm afraid it will affect your work. Xiaohu said.

"Didn't I say it, don't worry about her, you just come." Zhang Zhimu said: "That's it, tonight, after Xiaoqing finishes his homework, I'll teach you to swim." The swimming pool at Yaogang College has also been installed with light bulbs, and there is heating inside. ”

"Good! That's great. I learned how to swim and I could go down to the river to catch fish. Xiaohu said happily, and came over to take Zhang Zhimu's hand again, as if he was afraid that Zhang Zhimu would change his mind again.

Zhang Zhimu said: "You just play here, I'll talk to someone about work for a while, don't disturb us." Or you can go out and play with your aunts. ”

"Okay, I'm silent." Xiaohu agreed.

Zhang Zhimu asked Yang Yulin to send someone to find Li Di and Yang Chang.

Li Di has been focusing on power generation for a while.

As soon as he sat down, Li Di said, "Mr. Zhang, if you don't come to me, I will look for you." Our power plant should be in a different place, the safety of the cave is safe, but there are both granaries and barracks over there, and when we build a power plant, we not only need a space for the power generation plant, but also need a space for stacking coal and drying pools. It's just too crowded over there. ”

Zhang Zhimu said: "Tell me about your suggestions. ”

"I think so, do you think it's okay? Aren't we building a railway? The smelting yard and our kiln gang are about to build a railway, which means that it is not difficult to transport the coal to the kiln and then to the smelter. We might as well build all the big power plants on the other side, and we can use high-voltage power transmission to send electricity to the kiln gang. In this way, the kiln can not only occupy less space, but also reduce pollution. In particular, there seems to be insufficient electricity in the smelting field, and they have been given a small generator for a few days, but it is not enough. Why don't we make up our minds to directly build a large power plant, and in the future, our large generators can also be connected to the grid for power generation. Li Di seems to have made this suggestion after comprehensive consideration.

What Zhang Zhimu would like to see most is that they can use their brains to think about problems and ask: "Has the problem of transformers been solved?" ”

"No problem, we can solve the problem of excessive temperature with water cooling and air cooling. You said that the grid can be used to transmit millions of kilovolts. We didn't dare to use that high, but we discussed, we can use 10,000 volts to transmit electricity, and we can connect more insulated porcelain bottles on the high-voltage tower. Li Di said.

Zhang Zhimu said: "I support your proposal. My suggestion is that when you build a high-voltage power tower, you should build a higher one, we will not use 10,000 volts to send electricity forever, in fact, I tell you, in the future, I will get you transformer oil, which is the kind of oil that can put transformers in. In this case, refrigeration is not a problem. As long as the problem of insulation is solved, the difficulty of sending 10,000 volts is the same as that of 100,000 volts, but all kinds of switches and so on must be able to accept high voltage. In the future, you will have to build a laboratory that can be used for experiments and testing our devices. ”

Li Di said: "We want to do this, on the side of Yaogang, stop a small generator first, install a large generator, and do not delay the electricity first." It took longer to build a large power plant at the smelting field. ”

Zhang Zhimu said: "Okay, you have thought it through. But I have one more suggestion that you tell you about the steam engine. The temperature and pressure of the steam released from the cylinder of the steam engine are very high, and the steam can be used as the pressure source of the next cylinder to continue working, and even can be connected into three stages, so that the same steam engine is much more efficient. ”

Li Di said: "Great, Mr. Zhang, your idea is too good." We also felt that the steam engine was too inefficient, and we never came up with a good solution. ”

Zhang Zhimu said: "There is another small matter, there is a problem with the electric lights you installed for the college. I saw that you were just using a wire to hang a lamp for lighting. My suggestion is that you should only make a reflective shade for each lamp. This is not only beautiful, but also can reflect the light and improve the utilization of the light. ”

Li Di said: "Okay, I'll arrange for someone to fix this when I go back." ”

"Yangchang, how's your phone going?" Zhang Zhimu asked.

"We've finished the switch drawings and are asking the carpenter to make some frames. We also handed over the case of the telephone to Li Yunhe, and they did it. But we need to train the people on duty at the switch a little earlier. Articulate is required, preferably with a bit of culture. Yang Chang replied.

Zhang Zhimu knew that the person on duty at the switch should not only be like this, but also be absolutely reliable, he said: "Don't worry about it, the person on duty at the switch will be handed over to the command center, and the staff department will be responsible." ”

Yang Chang said, "Okay. ”

Zhang Zhimu said: "Yangchang, you want to select a few people for me who are very good at cultural learning and good at hands-on ability, and I want to start working on electron tubes, so that they can take over the past and continue to do it." ”

Yangchang said: "I've been waiting to get the tube, I'll participate in it myself." I promise not to delay anything else. ”

Zhang Zhimu smiled and said: "Okay, this tube is done, and it will open up a new world for us." I'm telling you, in the future, when we have an electronic tube, we will be able to make wireless telegraph calls. But there's so much you need to learn. I can also tell you that radio can be challenged in all areas of mathematics. ”

Zhang Zhimu is most worried that Yangchang's mathematical foundation is too poor now. During my four years of university study, I had a feeling that I was constantly learning mathematics, and I also knew that the mathematics courses taken by radio majors were a little less than those majoring in mathematics and physics. More than many other majors. Therefore, the people who find out to engage in radio should have strong learning ability, strong hands-on ability, and preferably a better cultural foundation. Yang Chang was originally a senior apprentice of Mr. Lu Bingyi and participated in all his courses. Now there are some foundations in electronics, and he is the most suitable person to come out and engage in electron tubes.

Zhang Zhimu, Li Di, and Yang Chang were studying energetically, and Yang Yulin came in and interrupted: "I'm sorry, interrupt, Ningde in Tongguan has arrived, Uncle Chen asked you to go over and pick it up." ”

Zhang Zhimu said: "Okay, we have time to talk about other things." ”

Li Di and Yang Chang had to pack up their things and leave, Zhang Zhimu came to Chen Yufeng's command center, and came out with Chen Yufeng to welcome him to the post of the kiln. It turned out that Ouyang He asked Li Jing to bring ten people and Ningde's ten personal soldiers to protect Ningde's return. When she arrived at Xiurong, Li Jing sent someone to ride a horse and come back first to inform her family. Chen Yufeng immediately notified Zhang Zhimu and Zhang Bingchen to come and pick up Ningde.

Chen Yufeng said to Zhang Zhimu: "I have already informed Ningde's family to prepare a better room for Ningde, and let Zhang Bingchen go to Ningde's house first and wait, ready for treatment." ”

Zhang Zhimu and the others came to the post, and after a while, they saw a team of people in the distance, escorting a rubber wheeled carriage running over. When he got closer, Li Jing hit the horse and ran over, and before he got off the horse, he said: "Uncle Chen, Mr. Zhang, Lord Ning has been asleep on the road. Let Zhang Bingchen take a look. ”

Chen Yufeng said: "Don't stop the carriage, go directly to Lord Ning's house." Zhang Bingchen is waiting there. ”

The kiln gang people arranged a small building for Ningde's family, and when the carriage arrived, Ningde's family cried and hugged to the carriage. Chen Yufeng shouted: "Get out of the way and bring the stretcher." At this time, Ningde's family got out of the way, and Zhang Bingchen and others slowly lifted Ningde out of the car and put him on a stretcher. At this time, Ning De woke up, saw Zhang Zhimu and Chen Yufeng, tears were about to flow, and just about to speak, he fainted again.

Zhang Bingchen carried the person to a room on the second floor, laid him flat on the bed, and brought a bulging bag made of rubber-coated canvas, put a thin rubber tube on Ningde's nostrils, and glued it with adhesive tape. This is to use an oxygen bag to give oxygen to Ningde.

Ningde's family didn't know what they were doing when they saw the kiln people busy, but they could only watch and couldn't say anything. Maybe it was the oxygen delivery that worked, and the Ningde monkey moved for a while. At this time, Zhang Bingchen drove everyone out, leaving only his disciples, and began to take off Ningde's clothes, re-examine Ningde's wounds, clean and change medicines.

Zhang Zhimu and Chen Yufeng had been waiting in the living room, accompanied by Ningde's family. Finally, Zhang Bingchen came out.

Chen Yufeng asked, "How is Lord Ning's injury?" ”

Zhang Bingchen said: "Lord Ning's injuries are very serious, but he should be stable now. The main thing was excessive bleeding, but fortunately, the wound was treated well at that time. After we gave him oxygen, Lord Ning's face was much better. It is estimated that there is no danger to life, just a good rest. The family can go in and have a look, but don't talk. Let the adults have a good rest, and I will come over tomorrow to change the dressing. Two oxygen bags are enough today. ”

Zhang Zhimu and Chen Yufeng comforted Ningde's family, called Li Jing and returned to the command center. Li Jing told her about what happened after she and Ouyang He arrived at Tongguan this time.

When Zhang Zhimu heard that there were more than 1,000 wounded, he said: "The placement of the wounded must be prepared first." ”

Chen Yufeng said: "Don't worry, Mr. Ouyang is prepared according to the placement capacity of 10,000 wounded, don't worry." During this time, Zhang Bingchen has been training personnel for battlefield treatment. When the time comes, Zhang Bengui will also bring his disciples over. ”

Zhang Zhimu said: "Li Jing take your brothers to take a good bath and rest, you haven't rested much along the way." ”

Li Jing said yes and went out. Chen Yufeng said: "Ouyang He has done a good job. There are still more than 3,000 Ning Debing left, and his soldiers are all veterans. We can pick out quite a few good ones. ”

Zhang Zhimu said: "Don't worry about this matter, wait for Ningde to get better and ask him what his opinion is." Besides, I think among the veterans of Ningde, it would be good if we could pick out half of the qualified ones. The main thing is that they are too old. ”

Chen Yufeng said: "We can let these veterans be police officers, and they are better than recruits in various cities, and they have experience." As long as we train well, we don't need to follow the rules. Besides, you can also send them to various construction sites to be small leaders. They have experience as soldiers, and they can still lead the team to work. But that's after the battle. ”

Zhang Zhimu said: "After the New Year, I will give classes to those literati we have brought back, let them go out to become officials, they will be happy, but they must do things according to our regulations." We will assign a team to them at the same time, take over the big cities, and recruit people to be officials in small places. ”

Chen Yufeng said: "You can take the exam to recruit officials." ”

"Great idea! In this way, we can make an impact. I just don't know what the emperor will think if he finds out? Zhang Zhimu said.

"Humph! At that point, we don't care what he wants. Chen Yufeng said.

"The emperor can't be too offended, and we have to deal with him." After speaking, Zhang Zhimu got up and said, "Okay, Uncle Chen, I have to go home, I promised Xiaohu and Xiaoqing to take them to learn to swim tonight." I need to go back early. ”

In the indoor swimming pool of Yaogang College, no one comes to swim at night at all. Only Zhang Zhimu took Xiaoqing and Xiaohu with them. However, it is impossible for Zhang Zhimu to swim in briefs in this era, and there is no more. In this way, Zhang Zhimu took Xiaoqing to swim, and had some trouble with Huang Yukun.

When they arrived at the swimming pool, Zhang Zhimu said to Xiaoqing and Xiaohu: "I'll go down and perform for the two of you first." ”

Xiaoqing and Xiaohu are of course happy to jump high.

Zhang Zhimu took off his clothes and tested the water temperature, and he felt okay. It's been a long time since I've been swimming in a pool. Zhang Zhimu moved his body well, and let Xiaoqing and Xiaohu follow the activity together.

After the event, Zhang Zhimu plunged into the water, making Xiaoqing and Xiaohu scream. However, Xiaoqing and Xiaohu breathed a sigh of relief when they saw Zhang Zhimu swimming from the bottom of the water to a distant place and showing his head again.

Zhang Zhimu performed breaststroke, backstroke, butterfly, and freestyle for Xiaoqing and Xiaohu, which made the two little guys jump happily.

After swimming for a while, Zhang Zhimu went ashore and blew the inner tubes of the two rubber wheels he brought, and it took a lot of effort to blow up the two tires. Then I put in the water, and because the water was a little cold, the tires were a little flattened. Zhang Zhimu asked: "Who of you knows, why the tires are deflated when they are put in water?" ”

Xiaoqing said: "I know that it is the principle of thermal expansion and cold contraction, and the air shrinks when it encounters cold water. ”

"Okay, that's right." Zhang Zhimu said.

Xiaohu was a little unhappy when he didn't answer, and said, "I'll go to school during the Chinese New Year, and I'll know when the time comes." ”

Zhang Zhimu said: "Yes, Xiaohu will go to school next year. By then, you'll learn a lot. ”

Zhang Zhimu once again blew the tires and asked, "Which of the two of you will go into the water first." ”

Xiaoqing said, "Let my brother go first." ”

Xiaohu was a little nervous, and Zhang Zhimu asked, "How manly is scared?" ”

Although Xiaohu was afraid, he still insisted on saying, "Uncle, I imagine you swimming like that." ”

"Good! The man went into the water with me. Saying that Zhang Zhimu put a tire on Xiaohu, he went down to the water first, and then followed Xiaohu in the water, Xiaohu's feet just entered the water, and he shouted that it was too cold and refused to come down, Zhang Zhimu deliberately said angrily: "Which looks like a man, come down." ”
