Chapter Ninety-Three: The Launching of a New Ship Powered Vehicles and Tracked Vehicles

It's time to prepare for the Spring Festival Gala again, and now the people's enthusiasm for the Spring Festival Gala seems to be getting higher and higher.

Editor-in-chief Fan, Class Master Liu and Xiao Hongyu came over to report to Zhang Zhimu on the preparations for the party, and wanted to ask Zhang Zhimu to come over to review it.

Zhang Zhimu smiled and said, "I won't go to you this year." I'm sure you'll make the party even better. Now our kiln gang has gathered almost the entire Ming Dynasty famous opera troupe, and there are many famous actors, and there is no shortage of program sources. Both radio and live galas should be equally important. I suggest that in addition to these two evening performances, the radio station can also hold a special opera performance, so that the famous actors of various genres can come together to perform once, and you can also hold a song party, so that those who sing well can have a chance to sing on the radio. I heard that Xiao Hongyu brought back a few singers from the northwest this time, and they should be given a chance to show up. ”

Editor-in-chief Fan saw that Zhang Zhimu was not going to review the evening program, so they didn't let him go again. Because they are already very familiar with the party now, they don't need Zhang Zhimu to worry about it anymore.

After Xiao Hongyu and they came back from the northwest, Zhang Zhimu and Xiao Hongyu met a few times, but they didn't mention marriage. Just talk about lovesickness together and kiss each other, of course, every time Xiao Hongyu refuses Zhang Zhimu's further request.

Little Hongyu was very busy when she came back. Filming movies here, she is the protagonist, and at the art academy over there, she has to worry about it, and she can't delay the performance of the troupe. Every time Zhang Zhimu saw her, he advised her to pay attention to her body and not to work too hard.

Little Hongyu Gege smiled and said, "You! Don't worry about me, you haven't looked, how many people in our kiln are busy day and night. The kiln has developed so fast, and everyone is busy. I think the busier I get, the more energetic I get. I used to sleep badly, but now I have my head on the pillow. Hehe! ”

Xiao Hongyu's conditions are also good now, with an independent small courtyard, and a maid cook has been invited from her hometown in the south. She doesn't have to worry about life, and she is even better at eating.

Zhang Zhimu doesn't have the heart to think about getting married now, and Xiao Hongyu also knows that she and Huang Yukun also need time to ease up. They don't even talk about marriage when they are together. In fact, Xiao Hongyu now knows that she and Zhang Zhimu are already inseparable from anyone. She's a person who can let go of things.

Now the two most popular words in the kiln are "movies", and these two words have added a topic that everyone talks about to the kiln gang a year ago. Those students were the first to see the documentary "Expedition to the West". Then all departments of the kiln gang took turns to watch this movie. The people outside and those who have access also watched the movie. Everyone went back to talk about the movie, and let those who didn't see it scratch their ears and cheeks one by one to find a way, and find a way to go to the movie. Not only do people want to watch movies and talk about movies, but now newspapers and radio stations are also commenting on movies. There are those who comment on the content of the movie, and there are those who discuss the movie. At the same time, it was leaked that "Tang Guifei" is also making a movie. This aroused the interest of the people.

In Huang Yukun's words, now that everyone is well-fed, they don't know what to do, so it's good if they don't make some idle things. Now that there is a movie, it's like losing my soul.

Zhang Zhimu admires Huang Yukun very much at this point, and she really sees the current problems in the kiln. Now the material life is getting better and better. In the past, people all over the street wore everything. Now there is a stable job, and no one will go to the street in clothes with patches. But when those people have money, they have nothing to do with entertainment except drinking, gambling, and prostitution.

Huang Yukun and Zhang Zhimu said that when the best business was Xiurong's brothels, Zhang Zhimu said, "Prosperity will inevitably prosper." ”

Huang Yukun asked angrily: "You can seal the casino, why don't you also seal the brothel?" ”

"Hey! As long as they do not force women into prostitution. We don't care about that. Zhang Zhimu said, "The Ming Dynasty did not prohibit them from doing business, and we don't care." ”

"The Ming Dynasty hasn't banned casinos yet?" When Huang Yukun chased and asked, Zhang Zhimu hid away.

In fact, one of the reasons that Zhang Zhimu didn't say was that now the kiln is prosperous and yin, and there are too few women. No kind of woman is worried about getting married, too many singles can't marry a daughter-in-law. You can't help but leave a way for the singles to live. But there is no such reason.

The kiln gang is like this, when everyone is busy, Zhang Zhimu often has to be more idle. This time, after he went to Lingshui Wharf to attend the launching ceremony of the two warships, he returned to Yaogang without following the ship for sea trial.

The ship numbers of these two ships are 102 and 103 respectively, because the ship number of Xiurong is 101, so it is lined up. 102 was named Fenzhou, and 103 was named Qinzhou. The 102 and 103 are 500 tons larger than the Xiurong tonnage, and many important improvements have been made. His front main gun caliber is 203 mm, which is the largest caliber cannon in the kiln gang at present. However, in order to be able to travel on inland rivers, the 103 and 102 were only lengthened in length. In addition to the carbon arc lamp used for the main searchlight, the other small searchlights were changed to iodine-tungsten lamps as the light source.

Zhang Zhimu didn't worry about the launching of the sea trial. He knew that the two ships were launched before they froze. They still have a lot of work to do, and it would be nice to be put into use before the beginning of spring next year.

Zhang Zhimu hurried back to Yaogang because he wanted to teach Yangchang and them a lesson before the year. Because Zhang Zhimu has long wanted to give them this lesson. Yangchang and they now have mastered the basic application of electric pipes, but their mathematical foundation is still too poor. Zhang Zhimu knows that the radio major can be challenged in all areas of mathematics. Almost all of the professional courses that follow wireless majors are math courses. Now it is impossible to teach them all the professional courses of radio in the past life, and I can't do it myself. Because I don't use many of the courses, I've almost forgotten them. However, they had to be taught the basics of systems analysis, and the content of the course was organized according to the current situation and what they thought they had to master. However, the most important thing is to add some mathematics content before teaching professional courses according to the needs of the content.

Yangchang and the others were happy to hear that Zhang Zhimu had time to give them a lecture. They know that every time they listen to Zhang Zhimu's lectures, they will be able to improve their skills a lot. Therefore, even if they don't understand Zhang Zhimu's lessons for a while and don't know what they are for, they will listen to them and digest them slowly. They knew that Zhang Zhimu would never tell them useless things. Yangchang: Almost all of them put down their work and came to listen to the class. The original small classroom can no longer sit for the people who listen to the lectures. Yangchang not only trained some people by themselves, but also divided many students who graduated from Yaogang College. In addition, Zhang Zhimu also invited Mr. Lu Bingyi and his disciples to come and listen to the class. Because this time, he's going to talk about something in mathematics that he hasn't talked about before. It must be useful to them.

However, they had a hard time listening to this lesson. Zhang Zhimu didn't feel surprised by this, because when he was in school, he didn't learn these things easily.

Zhang Zhimu first told them about complex variable functions and integral transformations. This is a challenge to Yangchang's mathematical ability. But Zhang Zhimu knew that if they wanted to be accomplished in radio, this was a hurdle that they had to pass. In the previous life, whether or not they could pass this level was also the main difference between those amateur radio amateurs and professional radio professional engineers. These contents, except for those with excellent talents, are difficult to learn on their own.

After talking about this, Zhang Zhimu knew that they couldn't digest it all at once. However, Zhang Zhimu did not have time to wait for them to digest it before giving a lecture on it. Then Zhang Zhimu focused on 'Fourier series and Fourier transform', and combined with these to talk about spectrum analysis.

Seeing everyone's faces full of confusion, in order to alleviate everyone's anxiety, Zhang Zhimu said: "I can see that everyone can't digest so many things at once." Don't worry, let's digest it slowly in the future. But you can forget about it, but one thing to remember is that by studying the Fourier transform, we can see that any electrical signal can be decomposed into a DC signal, a fundamental function, and some harmonic functions. Conversely, we can also use these decomposed signals to synthesize an electrical signal. Through spectrum analysis, we can better understand the significance of low-pass, high-pass, and band-pass circuits. It also lays a theoretical foundation for us to design circuits in the future. Through spectral analysis, we can see which frequency component is the energy component. ”

Zhang Zhimu's summary still made many people nod their heads. Zhang Zhimu knew that people who could understand these words had improved their understanding of radio by a big step. Zhang Zhimu combined with the course content to analyze the FM amplitude modulation signal.

Only then did everyone know that half of the bandwidth of the original amplitude modulation signal was useless and could be saved. Zhang Zhimu also introduced them to the concept of unilateral sidebands.

This time, Zhang Zhimu assigned Yangchang them a task, which was to engage in FM transmitting and receiving circuits. However, Yangchang they can't accept it, the FM signal occupies a much larger bandwidth than the amplitude modulation, but the noise is much smaller. Zhang Zhimu had no choice but to let them try it out. Of course, Zhang Zhimu did not forget to introduce them to several classic frequency modulation and demodulation circuits, as well as the principles of pre-emphasis circuits and pre-emphasis circuits.

Zhang Zhimu hurried up and spent more than a month to finish these courses for everyone before the year.

However, after listening to the class, Lu Bingyi and his disciples were extremely excited. Every time they got out of class, they were around Zhang Zhimu for the longest time. After Zhang Zhimu finished speaking, Lu Bingyi came over and said, "Mr. Zhang, you have opened another door for us. Mathematics is amazing, and what you said is enough for my disciples to go back and study it carefully for a while. ”

Zhang Zhimu said with a smile: "Hehe! Once they have digested it, they will apply it in our practice. In the future, we will need more and more of your disciples to participate in the calculations. ”

Yang Chang came over and said: "Mr. Zhang, this course has made us a big step forward in our understanding of the concept of radio signals. We know that all signals are made up of various signal components. When we receive a signal, we actually pick the component we need. ”

Zhang Zhimu let out a sigh and said, "Yangchang, you are just a little beginner now!" Take your time and digest what I've said. It will be of great help to you in the future. ”

After giving a lecture to Yangchang and them, Zhang Zhimu felt very relaxed.

There is already a strong New Year's atmosphere in the kiln. There were snowflakes floating in the sky, and Yang Yulin and Zhang Zhimu walked home together. Yang Yulin said: "When you go to work tomorrow, you will call Li Yunhe, he will always be looking for you." I told him that you should not disturb you while you were lecturing. ”

"That's right! Hehe, I wouldn't be able to finish my class if I listened to them. Zhang Zhimu said.

"And that Gonggong Li came again, and let me drive him away." Yang Yulin said.

"It's going to be the New Year, and the emperor is also coming." Zhang Zhimu said, "They are fateful, we don't know what taxes are like anymore." ”

"It should be fine, Uncle Yan, Old Dong Qiu, and Gongzi Li are not in Yaogang, and it is estimated that they will all go down to collect taxes." Yang Yulin said, "I said don't worry about it. Let's think about you and that little red jade! ”

"Hey! I don't have to worry about this matter, and I can't run away with her. Zhang Zhimu said deliberately not care.

"Don't have no conscience, people can sacrifice their lives to save you. Don't delay people anymore. Yang Yulin said, "You go back and talk to your sister-in-law, it's over one step." ”

"Huh! It's so fresh, and you guys marry your father-in-law like this? Zhang Zhimu felt a little ridiculous.

"I'm a sister-in-law, and I know what I have to do, so I might as well take the initiative to help do it, and I will do it for myself." Yang Yulin was honest, "It's just that I always feel that if I can give birth to a son, it would be good if you would marry her again." ”

"Hey! We now have two sons in our family, how good are two daughters? Zhang Zhimu said.

"I just want a son of my own." Yang Yulin said.

"Good! Go home and plant it tonight. Zhang Zhimu said.

Zhang Zhimu felt a sharp pain in his arm, but what came from his ears was "Say it!" Do not change the hexagram. ”

The matter of Xiao Hongyu is not something that Zhang Zhimu needs to solve immediately. He wouldn't mention it to Huang Yukun either. Zhang Zhimu knew that it wouldn't take long for Huang Yukun to be unable to hold back.

The next day, when Zhang Zhimu called Li Yunhe, Li Yunhe said, "Oops! You Miss Yang are also too powerful. I said that I was looking for you in a hurry, and he asked me, is the sky falling? You talk about it. ”

"Come on! Stop complaining. Zhang Zhimu said, "Sometimes I have to endure it." Tell me what's going on, shall we? ”

"Good! Come right here. Li Yunhe said.

When Zhang Zhimu came to Li Yunhe's office, Li Yunhe was waiting for them. They took the car together and left. Zhang Zhimu didn't ask him anything. Li Yunhe said: "It seems that the construction period of the Fenhe Bridge will be delayed a little. They had a lot of trouble hoisting the bow beam. Now I've finally figured it out. Use two tower cranes to lift the bow beam at the same time, that is, it cannot be lifted when the wind is strong. Be extremely careful when hanging. ”

"It would be nice to be able to open to traffic in the spring next year." Zhang Zhimu said, "I think, use this method to build another bridge in that place in Taiyuan." With ready-made experience, it should be quick. ”

"That's true, but the bridge in that place is half as long as this bridge." Li Yunhe said, "However, the water flow there is not so fast, so it should be easy to build." ”

The carriage came directly to the tractor test site. As soon as he entered, Zhang Zhimu saw a large tracked vehicle parked next to the site. This tracked vehicle, which is longer than a tractor, has seven load-bearing wheels. Take a closer look, there is also a large dump bucket that can be dumped on the car.

Li Yunhe asked proudly, "How is it?" Let them go in circles? ”

"Let's go in a circle!" Zhang Zhimu said.

The two drivers, hearing Zhang Zhimu say this, boarded the cab from the left and right doors respectively. Then there was a "boom", and a puff of black smoke came out of the smoke exhaust port of the crawler car, and the "boom" started. After changing gears, the tracked vehicle easily went around the factory. Zhang Zhimu felt that the crawler was faster than the tractor. asked Li Yunhe: "The speed is faster than the tractor, right?" ”

"Of course, the tractor doesn't need to go too fast. This car is transporting things, so it needs to be faster. Li Yunhe said, "It would be nice if our bucket truck was made to match him." After loading this thing into the car, when it arrives at the place, as soon as the hydraulic pressure is started, everything can be unloaded. With that, Li Yunhe went to the cab and said a few words to the driver.

The driver of the tracked truck starts the hydraulic control pump, and the bucket truck on the body is slowly erected, and then slowly lowered.

"Have you ever done an experiment with loading and unloading?" Zhang Zhimu asked.

"Of course, a lot of people were prepared to help load the car on those occasions, just to test this."

"Let's give birth! Mr. Tang, when they saw this thing, they didn't know how happy they could be? Zhang Zhimu said.

"The material is already being prepared, and the car and tractor can be put into production together with the new plant. That bucket still needs to be entered, and there are some undesirable places. Li Yunhe said, "Come and see this motorcycle again." ”

Zhang Zhimu followed Li Yunhe to several houses next to the venue and shouted, "Is there anyone?" Come out! ”

A few people immediately came out of the house. Zhang Zhimu knew at a glance that it was those who were originally engaged in gasoline engines and now engaged in power cars.

Seeing Zhang Zhimu coming, the team leader said: "Mr. Zhang, we have done a good job of powering the car, just wait for you to try it!" ”

"Good! Take it out and I'll take a look. "At this moment, someone pushed a motorcycle out of the house.

Zhang Zhimu saw that this motorcycle was similar to the sketch he had drawn for them.

Zhang Zhimu looked around the motorcycle and said, "Not bad." "It's good to get on a motorcycle and try shock absorption." Any of you can ride a lap, I want to see? ”

"Haha!" Several of them laughed. The team leader said, "We can all ride." Wouldn't it be a joke if we developed a power car and didn't know how to ride it? After speaking, the team leader rode on the power car, kicked with his foot, and the power car "beeped" out of black smoke and started. As soon as the team leader gave oil and released the clutch at the same time, the power car started. The team leader controlled the accelerator, and the power car ran around the test site quickly. Seeing that the team leader rode back, Zhang Zhimu couldn't help but say: "Great, it's just that the black smoke is a little bigger, and the sound is a little louder." Come over here and I'll try. ”

Zhang Zhimu took the power car, rode the power car and rode out as soon as he gave fuel. After riding a lap skillfully, he came back and said, "Everything else is good, but the brakes need to be adjusted more sensitively." Otherwise, in case of emergency, the braking will not work in time. ”

The team leader stumbled and asked, "Mr. Zhang, Mr. Zhang, when did you ride a power car?" It took us all half a day to learn. ”

Zhang Zhimu was stunned, he couldn't say that he was used to riding in his previous life, but Zhang Zhimu immediately said: "I ride a very good bicycle." Just control the throttle well. ”

Li Yunhe came over and said: "The shock absorption of the power car is good, and the road surface can almost be ridden." Much stronger than a bike. ”

"You make ten of them first, and then let everyone ride them on different roads, repeatedly. To be in the process, find problems, and then improve. And then it has to be mass-produced. First of all, it is necessary to equip the army. Zhang Zhimu said.
