Chapter 2 Talking about Marriage Parachute Typewriter

Zhang Zhimu, who returned home, suddenly felt that the home was very quiet, and Xiaohu and Xiaoqing saw that Zhang Zhimu was back and surrounded him.

"Yo! Why is the house so clean? Zhang Zhimu sat down and asked.

"My aunt has returned to her parents' house!" Xiaoqing replied while pouring water for Zhang Zhimu.

Seeing Huang Yukun just coming over, Zhang Zhimu deliberately said: "What a boldness! When I go back to my parents' house, I don't ask for leave first. ”

"Oops! Yulin finally survived until the full moon, and Mrs. Cai called again and again, and the couple went back to live for a few days. Huang Yukun replied with a smile.

At this time, Erhu came over and said, "I still have to go to the park to play!" ”

"Okay!" Zhang Zhimu pulled Erhu to sit on his lap and said, "I've had too much to do in the past few days. In a few days, my sister and brother will have a holiday, so let them take you to play. ”

Xiaohu came over and said to Erhu: "When I have a holiday, I will take you by bicycle!" ”

"Don't! I'm going to ride in a car like my mother's. "Erhu has an impression of riding in his mother's power car, and he likes it very much.

At this time, Xiaoqing came over and asked with a smile: "Uncle, when will you get me a power car?" Just like Aunt Hongyu. Mom's color is not good. ”

"When you and Xiaohu go to college, I'll buy you a power car when you want." Zhang Zhimu replied. Now Zhang Zhimu doesn't want them to be too special.

At this time, my cousin came over and interjected again, "Xiaoqing is too old to go to college, how can you get married, you don't want to think about it?" ”

"Cousin! There is no need to talk about this matter anymore," Zhang Zhimu was a little dissatisfied, "Anyway, Xiaoqing has to finish college." We Xiaoqing don't worry about getting married! ”

"I listened to my uncle, and I was going to finish college." Xiaoqing looked at Zhang Zhimu and said, "I always want to go to college in my dreams." ”

"No matter what you do in the future? You're all going to finish college. Zhang Zhimu said, "You haven't looked at Princess Anping, and now that you want to study in college, you feel too old and embarrassed." You must not delay. ”

Now Xiaoqing and Xiaohu are both tall and big men, this is because they are now well nourished, and when they catch up with their bodies, they participate in exercises again, and their complexion and mental state are very good. Looking at them, Zhang Zhimu was in a good mood. At this time, it is easy to remind Zhang Zhimu of his family in his previous life, but Zhang Zhimu has been able to do it, and in front of others, such a look swept away from his face.

With two crying babies, the family finally had a quiet dinner. Now, after Zhang Zhimu's serious training, my cousin can already make fish very delicious. Zhang Zhimu didn't understand why Shanxi people didn't eat fish before? Now the people of Shanxi are all over the street to open snack bars and taverns, which are inseparable from fish, and the big carp of the Yellow River and the fish of the Fen River that are sent to the kiln every day do not know how much, which is a matter of habit.

During the meal, Huang Yukun said to Zhang Zhimu: "You also ask Meng Si'er what's going on, he has been almost away from home for more than a year, what is he doing." His daughter-in-law didn't ask me much. I don't know how to answer either. ”

"yes!" Zhang Zhimu mentioned it by Huang Yukun, and also felt that Meng Si'er had been gone for too long, "Last time, when I saw Li Zhi, I heard him say a word about Meng Si'er. He said that Meng Si'er's work had made some progress, and also said that Meng Si'er said that he would not come back if he couldn't complete the task. Now they've been going for too long. I'll ask Li Zhi about it again tomorrow. ”

Maybe it's because the family has finally stopped a little, and Huang Yukun is in a very happy mood today, during this time, due to too many things, Zhang Zhimu has been sleeping by himself, and Zhang Zhimu and Huang Yukun are also particularly involved in a big battle at night.

After resting for a while, Huang Yukun suddenly said, "I talked to Xiao Hongyu again two days ago. ”

Zhang Zhimu thought to himself, "Oh, Xiao Hongyu is really amazing, why didn't she tell me about this at all." A woman's really can't figure it out. Zhang Zhimu originally wanted to finish his work and tell Huang Yukun about Xiao Hongyu, but after hearing Huang Yukun say it first, he was not in a hurry and asked, "How is it?" How did you talk this time? ”

"Humph! What's going on? Huang Yukun snorted and said, "You have already promised to marry someone after the southern expedition." What's the use of me saying? ”

"Oops! And when it came to you, it turned sour. Zhang Zhimu said, "You and Xiao Hongyu have been talking, and Xiao Hongyu asked me what to do?" You say what I say. I had to say that I was busy now, and I would talk about it when the southern expedition was over. That's what happens to you. ”

"After talking for a long time, it's not like you have to promise people after the southern expedition." Huang Yukun is not ambiguous.

"Forget it! Do not say. Zhang Zhimu said, "I also saw Xiao Hongyu today." Originally, I wanted to talk to you about Little Ruby. Look at you, you haven't said it yet, that's all. ”

"Oops! That's why you're working so hard to talk about this, right? Huang Yukun also began to be unreasonable.

Zhang Zhimu was so dizzy, he pulled the quilt and covered his head, and didn't want to say anything.

But Huang Yukun pulled down the quilt on Zhang Zhimu's head and asked, "Oh, you're really angry?" ”

"I'm not angry, I just didn't expect you to be so confused?" Zhang Zhimu said.

"My own man, why can't I make a joke?" Huang Yukun took Zhang Zhimu's arm and said.

"To be honest, when I was with you, I felt very grounded." Zhang Zhimu said.

"I believe what you say." Huang Yukun said, "But you are a peach blossom offender, from Yulin to Xiao Hongyu, you owe people's affection." That's what you have to deal with, and it's not a problem to hide like this all the time. This will delay the little red jade. ”

"Huh!" Zhang Zhimu thought it was funny, "I didn't expect that I still need a wife to worry about marrying a woman." ”

"It's definitely not your own business to marry a woman, it's as small as our family's business. It's a matter of the kiln, and then it's a matter of the world. I can't leave it alone. Huang Yukun said, "I told Xiao Hongyu that I would marry as long as I had time." Xiao Hongyu still lives in her own house, and you can live there whenever you want. We can't live in our house now. It's better to live separately so that you don't have too much trouble. ”

"Then wait for autumn! The floods have also gone down everywhere. When it's over, I want to accompany Xiao Hongyu back to her hometown to have a look. Zhang Zhimu said, "Xiao Hongyu is indeed a strange woman, and it is rare to be infatuated." ”

"I just think this woman is too smart." Huang Yukun said, "With your status, it may not be a good thing for a woman to be too smart." ”

"Don't worry!" Zhang Zhimu said, "Xiao Hongyu is willing to do something specific, let her do it." I'm not going to let me get involved in politics. ”

"Humph! I'm afraid I won't be able to help you when the time comes! Huang Yukun was still a little worried.

As soon as he arrived at class the next day, Zhang Zhimu called Xiao Hongyu and said that he could marry her in the autumn, but unexpectedly, Xiao Hongyu smiled and said, "Hey! I already knew. I finished discussing this matter with my sister-in-law, and I deliberately didn't tell you yesterday. ”

After listening to Xiao Hongyu's words, Zhang Zhimu felt uncomfortable in his heart, and said in his heart, who is going to marry a woman, and he has no right to decide.

Hearing that Zhang Zhimu had no voice, Xiao Hongyu was even happier, "Hehe! Don't worry about that! Ay! Can you remember what day it is? ”

Zhang Zhimu thought for a while, but didn't remember, "I really don't know what day it is!" ”

"Alas! Forget it, let me tell you, it's my birthday. Come to my house in the evening. I'm going to celebrate. Xiao Hongyu said with some disappointment.

"Oops! I really forgot that today is your birthday. I'll go over in the evening. Zhang Zhimu really can't remember these things, let alone Xiaohong's birthday, Huang Yukun and Yang Yulin's birthdays Zhang Zhimu can't remember either, his mind has never been on these things.

Putting down Xiao Hongyu's phone, Zhang Zhimu called Li Yunhe again and asked Li Yunhe to come over.

Li Yunhe thought that Zhang Zhimu was still looking for him for the delta wing paramotor, and as soon as he came in, he said, "Soon!" You don't have to rush. I've asked them to get three first, let's try first, what's the problem? After speaking, he unceremoniously poured himself a glass of water and drank it.

"Good! You just need to hurry up on this. Zhang Zhimu said, "However, I warn you." Fly with a paramotor, that's just to let everyone know that we can fly too. But paramotor is just a rudimentary thing. We're going to have to get airplanes in the end. Compared to airplanes, paramotors are not as good as power cars and cars. Once the paramotor can fly, you start working on real airplanes. ”

"Is it necessary to increase the power of airplanes?" Li Yunhe asked.

"Of course, it's not just about power, it's also about being lightweight." Zhang Zhimu said, "When I used to tell you about engines, did I talk about star engines? ”

Li Yunhe thought for a while and said, "That's right! At the time, I thought it was useless. The number of cylinders in the star engine is generally an odd number, there are five, seven or nine, and they can also be used in several rows to increase the power. I remember all of that. ”

"When you're done experimenting with the paramotor, you, who are developing the paramotor engine, will start developing a star-shaped engine that is as light and reliable as possible. It's not like a car, you just have to stop and fix it when it's broken. It flies in the sky, and if it is broken, it will fall down, and it will die. Zhang Zhimu said.

Li Yunhe touched his head and said, "The more we play, the more mysterious it becomes!" I can't even go down to heaven. ”

"So! I asked you to come today or I want you to get a kind of parachute. Zhang Zhimu said, "In the future, if our plane really has an accident in the sky, we will let the pilot come down by parachute." ”

"What do you call a parachute?" Li Yunhe asked.

"Kites can fly, right? Our delta paraglider can fly too, right? Zhang Zhimu said, "We increase the area of the kite, and the kite can bring people up." So let's make a big kite out of silk, so that when people fall from a high altitude on such a big kite, they won't fall directly to the ground, and they can live? ”

After speaking, Zhang Zhimu drew a parachute figure for Li Yunhe with paper and said: "In the future, we will use silk to make such a parachute, and then try to take such an umbrella to fall from a high altitude." With something, we will develop aircraft in the future, and maybe fewer people will die. Remember, we are bound to die when we develop aviation. ”

Li Yunhe looked at the parachute graphics drawn by Zhang Zhimu and said, "This is a bit interesting, but the difficulty lies in how they can unfold themselves in the air." The silk itself is very soft, and if he gets entangled with the rope, won't it be over? ”

"You're talking about the difficulty, when we fall from the sky, we also need a small guide parachute, and the big umbrella is pulled apart, so as to ensure that the parachute opens safely in the air. Of course, there are strict requirements for this parachute, parachute stacking method, etc. Zhang Zhimu said, "You must have a special team to study the parachute." Now you're going to build a skydiving tower to test parachutes and train people to skydive. The person is first tied to a parachute, then suspended in the air with a rope, and then lowered so that the parachute unfolds in the air. In this way, I slowly groped for the rules of the parachute. ”

"How tall is this skydiving tower?" Li Yunhe asked.

"At least fifty meters, right?" Zhang Zhimu said, "I think you should build a 70-meter-high one." Four parachute booms can be stretched out from the tower. Zhang Zhimu remembered the skydiving tower in Chongqing.

"Oh my God! Seventy meters high, that's the highest kiln. Li Yunhe said, "This matter still needs Lu Bingyi and their help to design it." ”

"That's right! You have to think about the functions and requirements before you go to Mr. Lu Bingyi. Zhang Zhimu said, "You need to set up a team to do this now, this is not child's play." ”

"In my opinion, I will set up an aviation research institute, and all things related to the sky can be assigned here to do it, and it will be easier to manage." Li Yunhe said.

"Hmmm! I agree with you. But I think it's called the Aviation Commission. Zhang Zhimu said, "It won't be long before aviation will play a big role." You're going to have some good people do it. ”

"No matter what we say now, we can still fly," Li Yunhe said, "and we will recruit students again soon, should we recruit two aviation classes first?" Four years later they graduated. We're going to make progress in aviation, too. ”

"I agree, just recruit a class with an aero engine major and an aircraft major. Talents should be cultivated in advance. Zhang Zhimu said.

"That's all that is said and done, there's one more thing." Zhang Zhimu said, "You have already learned 26 letters, haven't you?" ”

"Yes! Using letters is sometimes convenient. Li Yunhe said.

"You've seen us print in lead type, haven't you?" Zhang Zhimu asked again.

"Yes! What are you going to say? Li Yunhe said.

"That's the case, if we can't think of a printing house, simply print some alphanumeric and other things, can't we do it now?"

"Can't do it!"

"So I need you to make such a machine now, and put the commonly used letters and numbers, punctuation, etc., on such a machine, and each lead word has a corresponding button, and we need to print the required letters on the paper through the key. There should be functions such as positioning, wrapping, etc. Such a machine is called a typewriter. Zhang Zhimu said.

"Oops! This is not an easy matter. Li Yunhe said.

Zhang Zhimu's original office had one such old-fashioned English typewriter. Every time Zhang Zhimu saw this English typewriter, he would feel that human beings were really great because of its exquisite design, and he used relatively simple mechanisms to complete very complex tasks. When Zhang Zhimu and his colleagues talked about this, what a master said was very reasonable. He said that the typewriter that just came out could not be so perfect, and I don't know how many generations of things have been perfected to become like this. However, Zhang Zhimu did not study the detailed structure of this typewriter more closely. Therefore, Zhang Zhimu could only roughly draw a structural diagram of the typewriter for Li Yunhe, telling him what the printer keyboard looks like, where the printing hammer is placed, where are the buttons and the carriage enter and line feed, how to position, shift, etc. There is also the placement of the ribbon, etc.

After Li Yunhe listened, he lowered his head and thought for a while and said, "I'll get two of the people who are engaged in knitting machines to do this." Hey! The guys who made them knitting machines were really amazing, they made the knitting machines so clever. With just a few needles and a little variation, you can weave different things. I saw that I would transfer two of them out. ”

"Don't interfere with their work on the knitting side." Zhang Zhimu said, "The cotton vests they weave can be sold as much as they want." They have a lot to credit. ”

"However, it took a lot of effort to get this thing out, and it didn't make much use, right? What's the use of just printing these letters? Li Yunhe didn't understand.

"This thing is mainly used for Yangchang and their computers to make output equipment. It can also be used as a telegraph printing terminal. Zhang Zhimu said, "We can use a typewriter to output and print a digital telegram." It is also possible to connect perforated paper tape to automatically send and receive telegrams. ”

"Then we should work with Yangchang and them to make a typewriter that can automatically output and print, and at the same time can also print manually." Li Yunhe said.

"Isn't that more difficult?" Zhang Zhimu asked.

"Hey! It's okay. I think that's it. Li Yunhe is very confident, "It would be nice if I could print Chinese characters, and it would be much more convenient for all units to send documents and materials." ”

Li Yunhe's words reminded Zhang Zhimu, "Okay, let's invite Yangchang to come over tomorrow to study together." But your words remind me of something. I see that the drawings you use are all drawn by hand, right? ”

"Yes! And a drawing machine? Li Yunhe asked.

"There will be drawing machines, and they have to get their computers out of it." Zhang Zhimu said, "However, there can be a way. Make a few copies of the drawings you have drawn. Isn't it very useful. ”

"Of course it works." Li Yunhe said, "Tell me what can I do?" ”

"We can print more drawings in a similar way to photographing." Zhang Zhimu said.

"It's not okay if the photo is too small, and it's not good to deform it." Li Yunhe said.

"The method I'm talking about must work." Zhang Zhimu said, "We have to first produce a kind of sulfuric acid paper that can be partially transparent. Lay the original drawing on sulfuric acid paper and draw it with an ink pen to make a base map. Then use some photosensitive raw materials to coat the drawing, and then spread the base map on such a drawing for exposure. Where there is no obscuration of the lines on the basemap, the photosensitive material will be photolyzed into another material, and then we can use other gases such as ammonia to process the drawing to get the blueprint. "Zhang Zhimu knows how to paint the drawings, and there is also a way to smoke the drawings with ammonia. But I don't know what kind of photosensitive material is painted on the drawing.

"This seems to be a solution," Li Yunhe said, "but I don't know what photosensitive material should be applied to the drawings?" Do you still need Master Qingfengzi to participate in the development of this matter? ”

"Yes! Master Qingfengzi must be allowed to participate in this matter. Zhang Zhimu said, "However, you should go to the director of the paper mill and produce sulfuric acid paper first, so that Master Qingfengzi knows what the transmittance of sulfuric acid paper is, and they know what kind of photosensitive material to choose." ”

"Sulfuric acid paper?" Li Yunhe has never heard of sulfuric acid paper.

"That's right, sulfuric acid paper is easy to get. To choose a good pulp in the wet situation to make paper, but the pulp is not allowed to add anything else, fried paper, put in sulfuric acid for a few hours, and then treat with glycerin, so that the paper is transparent and waterproof, can be stored for a long time. You have to do it yourself. In the future, if we can post pictures, it will be much more convenient for everyone to work. There will be another job in the future, and that is the draughtsman. The cartographer chooses some girls who are educated, write well, and have a careful heart. Zhang Zhimu said.

"I knew that you would be indispensable when you looked for me." Li Yunhe muttered.

"Is this what can be done!" Zhang Zhimu said, "I don't think your tractor and automobile-powered car production should be separated? ”

"I was just going to tell you about it, too." Li Yunhe said, "The production of several tractors is in short supply. We're now working on the kind of walk-behind tractor you mentioned. I also think that if that thing is really like you said, there will be a greater market demand for our kind of thing. I would now like to divide the tractor factory into three plants. Another special vehicle production plant will be built, and those excavators, cranes, gun trucks, etc. will be produced by a factory. A special factory was set up for the production of automobiles and power vehicles. ”

Zhang Zhimu said: "It's okay for you to divide it like this now, and you may divide it more carefully in the future." As long as it is subdivided, each factory, everyone can pay attention to one thing, then the products produced can be kept improving. ”

"yes!" Li Yunhe said, "If we divide it too thinly, we can't disperse our forces too much." Let's break it down later! But I don't want to separate the engines yet, and I want to concentrate on them. Li Yunhe has his own ideas, and Zhang Zhimu doesn't want to interfere.

After talking to Li Yunhe, as soon as he was sent away, Zhang Zhimu didn't think he could catch his breath. Li Mao's call came again, and Li Mao wanted to invite Zhang Zhimu to drink together at night.

Zhang Zhimu knew that Li Mao was busy and wanted to talk about the founding of the party. However, Zhang Zhimu agreed to Xiao Hongyu to attend his birthday dinner today, and said to Li Mao: "Brother Li! The wine tonight is to be drunk. But you have to come with me. All right? ”

"Okay! Brother Xian, I'll listen to your arrangement tonight. Of course Li Mao agreed, but he didn't expect it to be Xiao Hongyu's birthday dinner.
