Go back to the past and be a schoolboy

Chapter 259

"Chirp~"

As the night deepened, the street lamps in the yard came on, and some moths began to flutter under the orange light, and the crickets in the nearby grass also began to play their songs.

Feeling the long-lost northern summer breeze, Cheng Nuo was in a good mood. He took the initiative to open the door and took two bamboo chairs out, and said cheerfully:
"Mr. Tesla, let's go outside, the room is too stuffy, and it's not easy to open our minds."

"Guests do as they please, please, Comrade Dean." Tesla bowed slightly and followed behind politely.

"Then I won't give you any humility." Cheng Nuo put the chair directly under the vines, turned around and waved to the back: "Don't hide now, we've all seen you, come out now?"

Just when Tesla was wondering, two people actually slowly moved out from behind the ginkgo tree not far away.

Who else, of course, is Shi Jin and Wu Yulin, just now they were just discussing things by themselves, they didn't pay attention to the situation in the room at all, it was already too late when Cheng Nuo opened the door, so they were so busy that they decided to hide Behind the tree, I was thinking to see if I could hide this embarrassing scene.

Shi Jin put his hands on his back and scratched embarrassingly: "Zhiyuan, how did you find us? The tree is quite thick, and it's late now, although there is a light, but you can't see the distance clearly, so you can still be seen You found it, you are too amazing, right?"

Unexpectedly, Cheng Nuo burst into laughter: "Haha, who said I saw you?"

Shi Jin was obviously stunned, and said in a puzzled way: "Didn't you just make it clear just now? You said you saw us here and let us come out. Why do you say that now?"

Wu Yulin's brain obviously turned faster, and his eyes stared at Dao: "Lao Shi, I understand that Zhiyuan was deceiving us just now, and he wasn't sure if there was anyone behind the tree, so he just yelled a few words suspiciously. Thinking of the two of us being thieves... Bah, what is being a thief is that you have been cheated out of your conscience."

Shi Jin suddenly realized, and said angrily: "Okay, my dear and respected Comrade Dean, I didn't expect that he would make dirty tricks when he traveled far away. It's really hard to guard against!"

Cheng Nuo was so happy that he couldn't stand still with laughter, so he just sat down on the chair: "Soldiers are not tired of deceit, and Zhuge has no such formation; if illusions are not too deep, Yanshi has no such machinery. Lao Shi, Lao Shi Wu, who told you not to go back at night and listen to the wall here?"

Originally, the two were wronged, but now that they were exposed, their faces became hot with embarrassment.

Fortunately, it was night, if it was daytime, I would have to crawl into the cracks in the ground.

The joke was over, and people were invited out. Cheng Nuo didn't want to leave them alone, so he pointed into the room:

"Okay, I guess you really want to hear it. It just so happens that we have something technical to share later, so you can sit and listen. But I won't move the chairs for you, and it will be your punishment."

The two were overjoyed after hearing this, and hurriedly ran into the house.

Not long after, one of them was holding two chairs, and the other was holding a small tea table, and rushed out of the house again, and at the same time, they even brought tea and pastries, which made Cheng Nuo amused again.

Tesla next to him watched all these processes, and the corners of his mouth rose slightly, obviously his mood was also quite good after being disturbed by this scene.

But jokes are jokes, when it comes to serious business, several people present are all devoted to it.

"In recent years, radio technology has developed rapidly. For example, the theory of electromagnetic wave propagation through the ionosphere and the principle of regenerative circuits were proposed, and then quartz piezoelectric oscillators, multivibrators, and bistable trigger circuits were developed. The manufacturing technology is the most advanced. Standout is General Electric's high-vacuum triode."

After saying this, Cheng Nuo unconsciously turned his gaze to Tesla, wanting to see his performance.

Sensing Cheng Nuo's gaze, Tesla shrugged his shoulders, meaning that he didn't care, but added from the side: "I know this, it was invented by that young man named Forrester, and I was very optimistic about this project at the time." invention of things."

Cheng Nuo secretly breathed a sigh of relief, and continued after reassuring: "Looking back at the development history of vacuum electron technology, we cannot ignore the Edison effect when Edison was studying the performance of incandescent lamps and found that metals can emit electrons when heated to a high enough temperature. .

Later, Fleming invented the vacuum diode on this basis, but in my opinion, it is the American scientist Dreyfus who invented the electronic tube to benefit mankind and create a new era of electronics development. The vacuum triode starts counting. "

In layman's terms, the control electrode of the vacuum triode is like a grid, which acts as a control valve, and can regularly change the size of the screen electrode current according to the change of the applied model.

The screen electrode current of the vacuum triode is much larger than the grid current, so the tiny electrical signal can be amplified many times after passing through the vacuum triode.

It is no exaggeration to say that the major achievements of modern electronics all originated from the invention of the triode. Without the principle of the triode, there would be no transistor, nor would there be the development of modern microelectronics.

After Forrester invented the vacuum triode, because he had no money to do further experiments to perfect it, he had to take his invention to some company bosses, hoping to get their funding.

Because of his shabby clothes and slovenly appearance, he found two companies in a row, but he was not even allowed to enter the gate.

When he arrived at the third house, he was taken to the public house as a fraudster outside the door, and the trial was held directly.

But a genius is a genius. Forrester directly publicized his invention in the open forum of the court, and it became a hit, received investment and successfully applied for the patent of the vacuum triode.

The triode is used in the screen pole detection circuit of the radio receiver, which greatly increases the communication distance.Soon the triode was used in the telephone amplifier again, which solved the key problem of the American long-distance telephone that Bell Telephone Company was designing at that time.

After pondering for a moment, Shi Jin said tentatively: "As far as I know, the vacuum triode is really good at the moment. This year, all kinds of popular radio telegraphs and electronic equipment have basically adopted this technology. We are also moving towards Is it going in this direction?"

Cheng Nuo waved the cattail fan in his hand and said, "Of course, the development of this technology is far from reaching its limit. Later, you can try quadruple, pentode, heptode, high-power transmitting tube, etc. There is a huge The family of vacuum tube devices is waiting for us to discover.

Radio is only our starting point. When the technical reserves are sufficient, relying on this platform, we can develop in the direction of long-distance radio communication, wireless telephone, radio, broadcasting, and high-frequency heating furnace. "

Of course, Cheng Nuo didn't directly develop his further ambitions, such as TV, radar, and more importantly, the killer electronic computer.

Even if he doesn't even have the qualifications to look up to now, it doesn't mean that Cheng Nuo doesn't have the ambition to yearn for now.

A big cake with thin skin and thick stuffing, even the well-informed Tesla, is also a little dizzy at this time: "So we are now on this basis, inventing a more mature and advanced high-vacuum vacuum cleaner than General Electric. Triode?"

"No, no, we don't need to fight hand-to-hand with the enemy on the dominant field. It will make us look very stupid. Besides, we don't have molecular pump technology, so it's even more difficult to fight against them on this track." Cheng Nuo shook his head, and immediately Seriously: "But, can we try to develop a new sealing process?"

Facing this new word, Wu Yulin and Shi Jin were both confused. You looked at me and I looked at you, and they all wanted to get some inside information from each other's faces. Unfortunately, after being confused, they greeted each other with disappointment.

Shaking his head, Wu Yulin asked, "Is it the technology to produce vacuum triodes?"

Cheng Nuo nodded and said seriously: "Yes, through this technology, our goal is to make the metal substrate and the glass can be connected to each other, and to make a breakthrough in vacuum tube sealing, so that high-power radio wave transmission can become a reality. Like the American folklore, the rich in the gold rush are not gold diggers, they are all selling accessories, and the reason is the same.”

When everyone praised him, Shi Jin suddenly asked: "But Mr. Tesla, the dean of the Institute of Applied Engineering, is the only person who understands this technology. Even if this technology is not difficult as you said, if we do it, I'm afraid It's not easy, is it?"

Cheng Nuo stopped the cattail fan in his hand, and sat up abruptly from the bamboo chair: "What you said is the key to our problem. The current scientific research, production and education are all in their infancy, and organic interaction and good cooperation have not been formed. In the past, they respectively restricted their respective in-depth development.

Scientific and technological research in Western countries precedes industrial production, which can provide mature theoretical and technical support for the manufacturing industry. On the contrary, in my country, scientific research lags behind industry. If things go on like this, this cycle can only lead to a dead end. "

Looking at Tesla who was silent at the side, Cheng Nuo suddenly laughed, and waved the cattail fan in his hand to fan Tesla: "Mr. Tesla, I just have some ideas about this, can you help me now?" When the time comes, no matter whether it is selling patents or licensing, the funding of the college will be settled again."

As he said that, Cheng Nuo combined the design ideas in his mind with what he had seen and heard in his previous life, and told them one by one.

Even if it is just a general description, the words are quite naive in the eyes of an insider, but for a genius like Tesla at this time, what is sometimes lacking is a flash of inspiration, followed by a spring of thoughts.

And Cheng Nuo's main role now is this, in charge of inspiration and brainstorming, and it's the kind of idea that can stand the test of history, and its practicability is ridiculously high.

At this time, Tesla rationally told himself that the wind from the fan was a cool breeze, but what he felt emotionally was obviously a heat wave.

"Cheng, your idea is like a genius. No, it is the devil in my opinion, and only the devil can get such a correct direction without technical verification!" Tesla said with a fanatical tone, very consternation.

Cheng Nuo couldn't help turning his head to the side, for fear that his blushing face would be discovered by the other party. The real situation is definitely not a devil-level genius. In fact, he has only just studied radio for a short time. The ship starts and ends tonight.

However, these words obviously cannot be said out loud. After hesitating for a moment, Cheng Nuo turned around and continued to fan the wind: "Mr. Tesla's words are exaggerated. What I want to ask is, is this plan highly feasible?"

Tesla excitedly said: "High, of course it is high, and we can even complete this process directly in the laboratory in a few days, and we can guarantee that we can mass-produce it at low cost without any investment from others. , the overall profit margin can go up to a higher level.”

Cheng Nuo hurriedly got closer and worked harder: "You don't need to put so much pressure on yourself, just let's carry it out steadily. As for the profit, we'll see later. Anyway, you're earning a dollar, so don't feel bad."

At this time, Cheng Nuo finally realized the importance of talent and the decisiveness of genius. He just proposed an idea here, but he didn't expect it to be implemented there.

This made Cheng Nuo couldn't help but have more expectations for Brother Haber who was far away in Europe.

"Brother Haber, you must be well. I am definitely not the one who publicized your war crimes and chemical weapons in major European newspapers and periodicals. They were all done by the Japanese. You are absolutely welcome in China. You will live here for the rest of your life." no problem……"

When Cheng Nuo was thinking about it, Shi Jin asked again: "But what are we going to do to snatch this order from the British guy this time? The preparations and preparations now seem to be planning for the future. The current problem It seems like I have no idea."

Unexpectedly, not only was Cheng Nuo not worried, but he laughed again, and said to Tesla next to him, "This related technology, in fact, we are not bad now, you know Mr. Tesla has been here for so long, But I’ve been working on radios in the lab.”

Tesla nodded, showing confidence in his smile: "Last month Marconi used equiradiant waves to transmit signals and sent the first wireless telegram in the UK and Australia, but what he didn't know was that this technology not only us With mature research results and simultaneous short-wave communication, we seem to have an advantage in comprehensive technology."

Cheng Nuo looked around, then covered his mouth with a cattail fan and said in a low voice: "Not only that, we are also researching coaxial cables, and we have made some progress. It can be said that they have some, we are not bad, we have some, They lack, for example, Popov's application to naval ship signaling."

After hearing this, Shi Jin immediately said excitedly: "This is great. With more advanced technology, I believe that the Beiyang government will never be so blind."

Wu Yulin is a little worried: "The problem now is that the initiative is not in our hands. When our technological advantages have not been extended to a certain extent, these people will still choose foreign products with a high probability. At this time, the more expensive it seems, the more worth looking forward to."

Hearing this, Cheng Nuo said calmly, "So we need to muddy the water, so that we can get a chance to make a move. What's more, what we are using this time is not the photo of the Academy of Sciences, but the American Fuxing Matheson Company."

"American Fuxing Company? What does this mean?"

Cheng Nuo smiled slightly and explained: "Of course it is a foreign firm affiliated to the Chinese Academy of Sciences of the United States of America. The legal representative is Mr. Nikola Tesla. Is this reasonable?"

"It's reasonable, it's too reasonable." Wu Yulin instantly understood what was going on, and applauded repeatedly: "We should have done this a long time ago. With this layer of foreign leather, these moths don't dare to be too presumptuous." gone."

"Then what do we do now?"

"Of course we will take our boss, Mr. Tesla, to the banquet of the Chief of Agriculture and Commerce!"
