Chapter 112: Try something other than math
There is an old man in the family, if there is a treasure.
At present, Nikola Tesla is definitely the oldest member of the Chinese Academy of Sciences, with rich experience and profound knowledge in the first half of his life, whether it is theory or practice, he is the top in the current industry.
Disassembling the AC motor of Huasheng Electric Appliance Manufacturing Plant, this big guy can directly get started with the operation, saying that he can use the existing machine tool in situ, hand rub parts, and reassemble a new machine, which is roughly the same in structure, but can be improved a lot in performance.
Looking at this emaciated big guy, facing the things he loves, he is really dedicated, and when it comes to professional content, he speaks very quickly, thanks to Cheng Nuo who is in charge of translation, if others are in charge, his head may not be able to keep up, not to mention that there are so many professional terms, many of them are the first time he heard them, and he was confused when he first heard them, and he had to interrupt a few times halfway before the conversation could go smoothly.
Rolling up his sleeves, Tesla picked up the chalk, wrote and drew on the blackboard prepared in the workshop, pointed to the sketch and said: "The basic equation of the AC motor generally assumes that the stator of the three-phase AC motor is symmetrical, that is, the stator cavity is circular and symmetrical on the magnetic circuit......
Yang Jichuan and several engineers in the audience nodded while listening, frowning from time to time, obviously some knowledge points are still difficult for them to understand, but the process of teaching can not be interrupted, write it down and wait until after class to ask, by the way, you can also engage in personal relationships, if you are lucky enough to open a small stove, it will be more perfect.
During the break, Yang Jichuan hurriedly pulled Cheng Nuo: "Professor Cheng, what are you going to do?"
Cheng Nuo didn't know why, so he glanced at the crowd next to him: "Put water in the toilet, in order to prevent heat stroke, I drank mung bean soup before I came, what's the matter, find me something?" You shouldn't be like those engineers, get together with Tesla and continue to ask questions, I think you remember a lot from the class just now, you have to seize the opportunity, you can't find me about the motor."
"It's really something, I just drank a lot of water, let's go together." Yang Jichuan glanced over there, and smiled: "The problem is the same, they have a young man who can speak English, and he will teach me when he comes back." You don't know anything about motors, but that's what I'm asking."
"That's it, let's go over together." This kind of feeling of several people meeting to go to the toilet, in a trance, actually had the feeling of going to school in the previous life, when I had to be a classmate, it seemed that one person could not complete this "arduous project", looking back at this bearded man, Cheng Nuo quickly shook his head and picked up this idea: "But the ugly words are said in front first, if you want to keep Tesla here, it will definitely not work, it is better to be mentally prepared."
"We know this, and we'll hurry up in time." Yang Jichuan walked beside him and said with a smile: "Actually, what we want to ask is how to entertain this distinguished guest, is there any special taboo in the diet, I will let the canteen make a small stove in a while, and treat you well before leaving."
Cheng Nuo tilted his head, looked at him seriously, pouted and smiled: "Okay, you old Yang, last time we came, we ate a big pot of rice, I didn't see you open a small stove for us, no wonder you have lost weight this time, is it that the small stove has eaten less recently, and the big pot of rice is not used to it." ….
Yang Jichuan patted his chest loudly: "Professor Cheng, you have wronged me, the master of the small stove and the big pot of rice are the same person, usually the workers and masters eat what I eat, where will there be special, besides, there were only a few people in our factory last time, just that pot, which is now the small stove."
"Okay, I understand the reason, I just talked to you about it." One-size-fits-all fairness is not necessarily good, Cheng Nuo joked, and said seriously: "What we eat, this foreign friend will follow what he eats, that is, pay attention to the taste matching to be richer, if you don't like to eat a single dish, we have something else."
Yang Jichuan hesitated for a moment, originally wanted to say that this would not be too casual, it seems that we don't pay enough attention to the guests, but the person was invited by the other party, and he is also his employee, and he is the big boss of this factory, so it is not good to say anything more, nodding: "Cheng, I will rest assured with this sentence, and I will buy some vegetables from outside later."
This time, Cheng Nuo did not object, it is appropriate to entertain guests enthusiastically, but he just doesn't want to face foreigners, so that the Chinese people will naturally bow their heads and wronged themselves to accommodate others, which will only make people look lower and lower: "This is okay, there are dishes and soups, hot and cold, reflecting our characteristics, our food is much better than their Western food, which makes Mr. Tesla also open his eyes."
After Yang Jichuan calculated the target hotel in his heart, he regained a smile on his face: "Okay, do you want me to prepare some wine, foreign wine is fine, if you trap this foreigner, lest he be like Little Japan, he must always hide his hand when he sells things to us, and he is not a thing."
Thinking about Tesla's age, Cheng Nuo hurriedly shook his head: "Forget it, drinking alcohol is too harmful to the body, just eat some home-cooked food, technically, you can rest assured, at present, we are on this road, we can't go back, and we will definitely not keep it, besides, you still have to research and tackle key problems, if you can, you won't drink."
Looking back at Yang Jichuan, Cheng Nuo suddenly smiled and said: "This product is the same as being a person, the strength has gone up, people will naturally look at it, just by bending the knee, it will only make people feel that we are better bullied, and the technology will definitely be given, but the high probability of getting it is eliminated by others, and at that time, with this kind of thing in the market, how can we have any competitiveness at all."
Yang Jichuan was silent for a moment, and said with relief: "Eating bagasse that others have chewed, there must be no sweetness, it's me who is obsessed."
The two stopped talking, and soon came to the toilet, and after finishing the matter, Yang Jichuan was busy with the hospitality, so he left first.
Coming to the washbasin, Cheng Nuo was washing his face slowly, just for a while, his upper body was almost soaked with sweat, and he could even see the shape of the salt, I really missed the days when there was air conditioning.
If nothing else, even if there is no air conditioning, just to escape the heat, you have to get the fan out as soon as possible.
Just when Cheng Nuo's thoughts were forked, he picked up a handful of water and was about to pry it on his face, when he suddenly found that the sunlight was not so strong, and with the help of the reflection of the pool, a figure shrouded him.
After a slight pause, the water had to be touched on his hands, Cheng Nuo then washed his face, and wiped his neck by the way, and suddenly felt much more comfortable. ….
"I said, Dean Cheng, what were you and Director Yang muttering there just now, laughing so hard that people's backs chilled, when I heard you mention Mr. Tesla, did you secretly discuss how to eat people alive?"
"you." Cheng Nuo picked up a handful of water again and splashed it to the side, for a person who is familiar enough, as long as he listens to the footsteps and looks at the back, he can basically guess the difference, it is obvious that the person who came is his Harvard mathematics classmate Jiang Zuo, and he is not so taboo verbally: "Can it be sold, let's not do a knife deal."
After Jiang Jiang Zuo dodged the handful of water, he leaned against the fence of the pool: "I remember when you said that it is called sustainable fishing without water, right?"
Cheng Nuo shook the water in his hand and said with a smile: "You, don't talk about this, I remember that you just got a doctorate in mathematics at the beginning of the year, why did you come back now, was it because you were disliked by your mentor and too stupid, you were kicked out of the school, and you have no face to stay in the United States?"
Jiang Jiang Zuo originally wanted to refute, but suddenly thought that there was really no way to compare with this person in terms of IQ, so he said a little helplessly: "What's the matter, the topic of the paper has just been reported, and the tutor is still reviewing it, thinking that he understands him, but he didn't know until half a year later, this is not stained with Mr. Tesla's light, and I ran over in advance to see our legendary Academy of Sciences."
Wiping his chin and removing all the water from his face, Cheng Nuo asked, "Then what are your plans for the future, the doctoral degree in mathematics is not so easy to get, and it is estimated that it will take two years to graduate."
Jiang Jiang Zuo turned on the faucet, originally preparing to wash his face, but when he heard this, he screwed it on again, and said suspiciously: "Come back, no matter how good the days are over there, it's not what I want, it's a desert of food over there, and I have already eaten and vomited when I eat potatoes every day, or our rice is paired with the aroma of meat."
Cheng Nuo opened the water dragon mouth for him, and said seriously, "I think that not everyone needs to come back."
Jiang Jiang Zuo asked while washing his face: "What's the matter, the undergraduates dislike me as a doctoral student and don't use it, you are a person, if you have a new person, you forget the old one, you should really give you a dog's head and a public trial on the spot."
Cheng Nuo explained, "That's it
Later, whether it is applying for patents as before, buying new equipment, or hiring talents, this is a major event related to the development of the Academy of Sciences, and it is impossible to hand over this kind of work to outsiders, it just so happens that others have no experience, but you have it."
When Jiang Jiangzuo heard this, he immediately screwed the faucet, water droplets fell from his bangs, and he waved his hand again and again: "I can't do this job, the last time I successfully applied for a patent and successfully negotiated a business, nine-tenths of the credit must be attributed to Mr. Tesla's head, I will run errands at most, do some document sorting work, and I will stay enough overseas for that day."
Cheng Nuo was prepared for this attitude and persuaded: "But the problem is that no one else has done this tenth, and this aspect has been ahead of us, and you have the most experience.
"I know this, why, you won't beat my mind at that time, and I don't know about France." Jiang Jiang Zuo still resisted. ….
"Hey, let me state that it wasn't then, but when I came back from the United States, I already had this plan." Cheng Nuo smiled and explained: "The so-called work-study program, that is, after learning technology in China, continue to work in France to earn tuition and miscellaneous fees, and work for others, at the moment their people are busy fighting and lacking people, so they naturally welcome us, but the war will always end one day, when a large number of soldiers will be discharged, jobs will become scarce, and then it will be difficult for our students to compete with the locals, and if they lose their part-time, where can they go to thrift?"
"Yes...... But even if I go, I don't know the place well, what can one person do, it's too weak to do big things directly." They are all people who have studied abroad, and they know too well that it is not easy for everyone, not to mention that they are going abroad at public expense, so they don't have to think about the cost at all, put themselves in their shoes, and feel that it is not easy for this group of students to study abroad in the future.
Cheng Nuo saw that there was a play, and said with a smile: "It's easy to say, you don't need to do it yourself, on the one hand, there are dozens of people from the Academy of Sciences to make technical reserves for you, and what you take out is definitely a good thing, on the other hand, you just need to help bring out a few subordinates, and the arrangements behind are up to you."
With Cheng Nuo's understanding of him, with Jiang Jiangzuo's strength, he can get a doctorate in one or two years, which is not very scarce for mathematical talents, but there is a big gap in other backbones stationed abroad, and he can't stay abroad all the time, and the focus of his work is in China, but students studying in France are also an important manpower supplement for the Academy of Sciences in the future, and they are also very important, so this job cannot be handed over to outsiders.
After thinking about it, my eyes were redirected to this mathematics student, where I could try to train a few of my own people, develop some backbones, and then use them specifically for this kind of thing.
What's more, in the future of the development of the school industry, the market can not only be limited to the country, it can be shipped to Europe to sell after the production is completed, not to mention, the electric fan produced by Watson Electric Appliance Factory can be considered at present, and the radio can be also shipped to Europe for sale.
After all, no matter how compressed the cost is, the price of industrial products is not something that most Chinese people can afford in this era, otherwise the ore radio mentioned above will not have a market until the reform and opening up, just because everyone is tight in their pockets, eating is a problem, how to enjoy the spirit.
Imagine that the scale of Watson electrical appliance manufacturing plant will be increased to open a new factory in Beijing, which is the work-study class in Changxin store to learn this technology, and so these students are skilled in a year and a half, basically it is time to go to France to study, then directly open a factory in Europe, directly can do seamless, the factory does not have to worry about the problem of workers, students can also solve the problem of work-study positions, killing two birds with one stone.
After learning of Cheng Nuo's plan, Jiang Jiangzuo was both admiring and helpless: "Tell me, I have worked so hard, although I haven't gone through the entry procedures yet, I have done so much work for you, and there is still a lot of things waiting for me in the future, do you want to give me a salary?"
Cheng Nuo laughed: "Of course it's no problem, you will be given an allowance according to the treatment of a full professor, and even your daughter-in-law will help you find it." ….
Jiang Jiang Zuo's face was full of disdain: "Cut, you are all a bachelor, let you pull the red line for me, when will you be a head, I still think for myself."
But then again, the money is used on the blade, and the allowance is forgotten, as long as I don't have to advance the money, because I'm satisfied."
Cheng Nuo smiled: "Friendship is friendship, allowance is allowance, only talking about dedication and not talking about return is playing hooligan, rest assured, what should be given to you will definitely not be less, it is all deserved."
With that, the two washed their faces by the sink again, returned to the workshop, and began the busy afternoon.
With the help of Tesla, a theoretical and technical expert, the new domestic AC motor was quickly assembled, and while it was more petite, the power was doubled, and the noise was less and the power consumption was lower, which was at least two versions higher than the previous motor.
Take out the new fan shell designed by Cheng Nuo before, debug it slightly, and install each part in place one by one, and it didn't take long for this brand-new domestic electric fan to come out.
Under the eager gaze of everyone, Cheng Nuo turned on the power and turned on the switch himself.
"Whew~"
The blades of the three copper fans quickly turned, and a cool wind immediately blew towards everyone, and the sound of the fan could only be heard in the quiet workshop.
Feeling this coolness, everyone held their breath, and it seemed that what was blowing on their faces was not the wind, but something else, which was simply intoxicating.
Some of the workers who were in a hurry directly surrounded them, pulled off their hats, and cheered on the spot.
On this occasion, everyone is also talking.
"This is the wind blowing by an electric fan, which is more comfortable than when my wife touched my face for the first time when I first entered the cave room."
......
"Look at this wind, it's much stronger than their American products, and when we mass produce them, I'll definitely buy three."
"What? Do you have a place to put it in your house after buying so much?"
"Isn't it possible to keep one for yourself, one for your daughter-in-law's family, and one for your mother's family?"
"If you want me to say, it's better to buy something else, you buy an electric fan, these old people may not be willing to turn it on in order to save electricity, and it will only fall into ashes."
......
"Not to mention, it's worthy of the gringo introduced by Professor Cheng, doing this job is to have a hand, this little wind is buzzing, making people feel comfortable, much stronger than the last time we assembled."
......
Looking at this electric fan, Yang Jichuan couldn't hide his excitement on his face, and asked Cheng Nuo vigorously: "Professor Cheng, we have succeeded, you tell me, you tell me quickly."
Cheng Nuo held his shoulder and said with a smile: "The wind is so strong, and the technology is more professional than mine, from a consumer's point of view, it must be a success, this kind of wind power is definitely far superior to the American 'strange brand, electric fan, let's make something."
Yang Jichuan didn't see it, nor couldn't feel it, but it took several years of hard work, and he went through ups and downs in the middle, just for such a day, now that he saw the product with his own eyes, he actually had a sense of unreality, so he asked others, and now he got an accurate reply, and his eyes were fiercely red.
"Okay, I can finally come up with such a thing, and I finally have an explanation, and I don't want everyone's support." ….
Immediately, his legs weakened and he was about to collapse to the ground.
Cheng Nuo's eyes were quick, and he hurriedly supported him: "Lao Yang, where is this, didn't we just take out the product, we are still waiting for mass production later, and then there will be promotion, sales, after-sales and other work, all waiting for you to check it."
As soon as he heard this, Yang Jichuan smiled bitterly and said, "Professor Cheng, you can do it all by me, I was empty just now, but I didn't expect to hear this, and I panicked instantly."
Cheng Nuo helped him to the chair and said with a smile: "Heavy medicine is needed to treat serious diseases, have you found your head again now, don't worry, you won't be idle, there are a lot of technical difficulties waiting for you to overcome."
It's not Cheng Nuo who is joking here, snatching the market occupied by foreign goods, in addition to allowing more people to enjoy the convenience brought by industry to life, there is also the purpose of cultivating industrial workers, every worker in the workshop is a good seed in his heart, and he will be able to take root and sprout in various places in the future, so as to give birth to more
of workers.
At the same time, Cheng Nuo values the AC motor the most, professionally speaking, in fact, any input current or output current can be called an AC motor, there are synchronous motors, asynchronous motors and AC commutator motors and other types, which can be single-phase or multi-phase. Single-phase is mostly used in household electrical equipment, agricultural machinery and electric locomotives, two-phase AC motors are mostly used in the field of automatic control, three-phase AC motors are the main power equipment for industrial production, and multi-phase is generally symmetrical three-phase or two-phase.
It is no exaggeration to say that special AC motors can also be developed and directly used in automobiles or aviation generators. Due to the versatility of alternating current, it is easy to perform various voltage changes and frequency changes, and various levels of voltage can be obtained at the same time, so as to meet complex needs.
Of course, in addition to these AC motors can also ensure the power supply of high-power electrical appliances, which can be used in aviation generators, during World War II, through the Yunnan-Burma line, the United States put into operation two three-phase alternators in Dashan, Guizhou, to help local military facilities and ordinary people generate electricity, and made a significant contribution to the War of Resistance against Japan, and even until more than 70 years later, the two AC motors are still working diligently.
In addition to these, the mass of the tractor alternator is 40 to 60 percent less than that of a DC motor of the same capacity, so the consumption of copper and electrical steel is also much reduced.
This means that the industrial strength of Chengnuo has accumulated enough, and when you want to build tractors, the technology is more mature, the cost is lower, and you can quickly put it into the agricultural market.
At that time, the outbreak of the Anti-Japanese War, the use of tractor assembly lines, on the basis of the transformation of directly to build tanks, just like the Stalingrad Tractor Factory, the T-34 medium tank and KV heavy tank, of course, we also have similar Luoyang tractor and so on.
One ring after another, Cheng Nuo believes that as long as there is enough time, he can definitely see the day when the tank is born from his hands, don't ask, ask is that the school is too big, the security guards patrol on foot is too slow, and the patrol car built by the school casually, the final interpretation right belongs to the Chinese Academy of Sciences.
Of course, the meal has to be eaten one bite at a time, the road has to be walked step by step, the AC motor is just a part of that huge industrial product, and there are many things to do later.
Looking back at the workshop, Yang Jichuan was beckoning the workers to keep the board book on the Tesla blackboard, saying that he would take it away and frame it, keep it for new employee training, and no one was allowed to touch it.
I can't help but sigh in my heart, with such a group of guys behind it, it doesn't seem like a dream to build a tank.
Stinging thunder
