"Chirp~"

As the night deepened, the street lamps in the yard turned on, and some moths began to flutter under the orange light, and the crickets in the grass next to them began to play a magnificent song.

Feeling the cool breeze of the northern summer that he had not seen for a long time, Cheng Nuo was in a good mood, took the initiative to open the door and carried two bamboo chairs out, and said happily:

"Mr. Tesla, let's go outside, it's too stuffy in the house, and it's not easy to open your mind."

"Guests are as you please, Comrade Dean, please." Tesla bowed slightly and followed behind politely.

"Then I won't give you modesty." Cheng Nuo directly put the chair under the grapevine, and turned around and beckoned to the back: "Don't hide now, we all see you, hurry up, let's come out?" ”

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

Who else could be, of course, Shi Jin and Wu Yulin, just now the two of them only cared about discussing things for themselves, and they didn't pay attention to the situation in the room at all, and it was already late when Cheng Nuo opened the door, so he was so busy that he simply hid behind a tree, thinking about seeing if he could hide this somewhat embarrassing scene.

Shi Jin embarrassedly put his hand on his back and scratched: "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, you can still find it, you are too godly, right? ”

Unexpectedly, Cheng Nuo actually laughed: "Haha, who said I saw you?" ”

Shi Jin was obviously stunned, and said casually: "Didn't you directly pick out what you said just now?" Said that he saw us here, and let us come out, why do you say that now? ”

Wu Yulin's mind obviously turned faster, and his eyes glared: "Lao Shi, I kind of understand, Zhiyuan was cheating on us just now, he wasn't sure if there was anyone behind the tree at all, he just yelled suspiciously, I didn't expect the two of us to be thieves...... Phew, what is a thief, it is a weak heart that has been cheated. ”

Shi Jin suddenly realized, and said a little angrily: "Okay, my dear and respected comrade dean, I didn't expect that when I went far away, I would make a shady move, it's really impossible to prevent it!" ”

Cheng Nuo was so happy that he couldn't stand on his feet with a smile, so he simply sat on the chair: "The soldiers are not tired of cheating, and Zhuge does not have such a formation; If it is said that the illusion is not boring, there is no such machine as Yanshi. Lao Shi, Lao Wu, who told you not to go back at night and listen to the root of the wall here? ”

Originally, the two of them were at a loss, but now after being pierced, their faces are hot.

Luckily, it's night, so if you have to get into the cracks in the ground during the day.

The joke was also made, and the people were invited out, and Cheng Nuo didn't want to continue to hang them, so he pointed to the house:

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

The two of them were overjoyed when they heard this, and they hurriedly ran to the house.

After a while, one person hugged two chairs, and one person held a small tea table and drove out of the house again, and at the same time, he actually brought tea and pastries, so that Cheng Nuo was happy again.

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

But jokes are jokes, and when it comes to business, several people here are fully engaged in it.

"In recent years, the rapid development of radio technology, such as the theory of electromagnetic wave propagation through the ionosphere and the principle of regenerative circuits, and then the development of quartz piezoelectric oscillators, multivibrators and bistable trigger circuits, etc., the most prominent manufacturing technology is the high vacuum transistor of General Electric."

After saying this, Cheng Nuo unconsciously set his eyes on Tesla, wanting to see the other party's performance.

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

Cheng Nuo secretly breathed a sigh of relief, and continued after relieving his heart: "Looking back on the development history of vacuum electronic technology, we can't ignore Edison's discovery that when Edison studied the performance of incandescent lamps, he found that metals can emit electrons when heated to a high enough temperature.

Later, on this basis, Fleming invented the vacuum diode on this basis, but in my opinion, the vacuum diode invented by the American scientist Dreyvorst began to benefit mankind and create a new era of electronic development. ”

Generally speaking, the control pole of the vacuum triode is like a grid, which plays the role of a control valve, which can change the current of the screen electrode regularly according to the change of the applied model.

The screen current of the vacuum triode is much larger than that of the gate 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 are all derived from the invention of the transistor, without the principle of the transistor, there could be no transistor, and there could be no 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 the owners of some companies, hoping to get their funding.

Because of his shabby clothes and unkempt appearances, he looked for two companies in a row, but he was not even allowed to enter the gate.

When he arrived at the third house, he was sent to the public house as a fraudster outside the door and tried directly.

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

The transistor is used in the polar detection circuit of the radio receiver screen, which greatly increases the communication distance. Soon the transistor was used in telephone amplifiers, solving a key problem with the American long-distance telephone that the Bell Telephone Company was designing at the time.

After pondering for a moment, Shi Jin said tentatively: "As far as I know, the vacuum triode is really good at the moment, and this year's various popular radio receivers and electronic equipment are basically using this technology, are we also developing in this direction?" ”

Cheng Nuo shook the pu fan in his hand and said: "Of course, the development of this technology is far from reaching the limit at present, and the quadode, pentode, heptade, high-power transmitter, etc. can be tried, and there is a huge family of vacuum tube devices waiting for us to discover."

Radio is only our starting point, and when the technical reserves are sufficient, we can rely on this platform to develop in the direction of long-range radio communication, wireless telephone, radio, radio and high-frequency heating furnaces. ”

Of course, the deeper ambition of Cheng Nuo did not directly expand, such as television, radar, and more importantly, the killer electronic computer.

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

After a thin skin and thick filling of the pie, Rao is a well-informed Tesla, who was also a little dizzy at this time: "So we are now inventing a high-vacuum transistor that is more mature and advanced than General Electric on this basis?" ”

"No, no, we don't need to fight the enemy on their advantageous field, it will make us look very stupid, not to mention that we don't have molecular pump technology, and it is even more difficult to compete with others on this track." Cheng Nuo shook his head, and then said seriously: "However, can we try to develop a new sealing process?" ”

In the face of this new word, Wu Yulin and Shi Jin are both confused, you look at me, I look at you, they both want to get some inside information from each other's faces, but unfortunately they are disappointed after being at a loss.

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

Cheng Nuo nodded and said seriously: "Yes, through this technology, our goal is to make the metal substrate and the glass dock with each other, and make a breakthrough in the sealing of vacuum tubes, so that the high-power emission of radio waves can become a reality." Just like the American folk language, the rich in the gold rush are not gold diggers, they are all selling accessories, and the truth is the same. ”

When everyone applauded, Shi Jin suddenly asked: "But at present, Mr. Tesla, the president of the Academy of Applied Engineering, is the only one who understands this technology, even if this technology is not very difficult as you said, but if we want to do it, I'm afraid it is not very easy, right?" ”

Cheng Nuo stopped the pu fan in his hand and sat up from the bamboo chair suddenly: "What you said is the crux of our problem, the current scientific research, production and education are all in their infancy, and they have failed to form organic interaction and good cooperation, which in turn restricts their own in-depth development."

Western countries' scientific and technological research precedes industrial production, which can provide mature theoretical and technical support for the manufacturing industry, while China's scientific research lags behind the industry, and this cycle can only lead to a dead end in the long run. ”

Looking at the silent Tesla on the side, Cheng Nuo suddenly laughed, waved the fan in his hand and took the initiative to fan Tesla: "Mr. Tesla, I just have some ideas in this regard, can I ask you to help the staff now, whether it is selling patents or licensing, the funds of the academy will be settled again." ”

As he spoke, Cheng Nuo combined the design ideas in his previous 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 naïve in the eyes of the insider, but at this time, a genius like Tesla, sometimes what is missing is a flash of inspiration, and then thoughts are like springs.

And Cheng Nuo's main role now is this, responsible for inspiration and brainstorming, and it is also the kind of idea that can stand the test of history, and the practicality is ridiculously high.

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

"Cheng, you are simply a genius idea, no, in my opinion, it is the devil, and only the devil can get such a correct direction without technical verification!" Tesla had a frenzied tone in his mouth, very stunned.

Cheng Nuo couldn't help but twist his head to the side, for fear that his blushing face would be discovered by the other party, the real situation was definitely not a devil-level genius, in fact, he had just studied radio for a short time, and he was full of calculations from the beginning of boarding in Shanghai to tonight.

However, this obviously couldn't be said, and after hesitating, 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 feasible?" ”

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

Cheng Nuo hurriedly got closer and was diligent: "Don't put so much pressure on yourself, let's just implement it steadily, as for the profit or something, let's see later, anyway, it's a beautiful knife, don't feel distressed." ”

At this time, Cheng Nuo finally realized the importance of talents, as well as the decisiveness of genius, he just put forward an idea here, but he didn't expect it to be implemented there, and he could draw inferences from one another and play more tricks.

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

"Brother Haber, you must be good, it is definitely not me who publicizes your war crimes and chemical weapons in major European newspapers and magazines, they are all done by the Japanese, China definitely welcomes your arrival, and it is no problem to settle down here for the rest of your life......"

Just as Cheng Nuo was full of thoughts, Shi Jin asked again: "But what are we going to use to snatch this list from the British this time?" At present, the preparations are coming and going, and it seems that they are all planning for the future, and there seems to be no idea about the current problem. ”

Unexpectedly, Cheng Nuo not only didn't worry, but laughed again, and said to Tesla Nunu next to him: "This related technology, in fact, we are not bad now, you must know that Mr. Tesla has been coming to us for so long, but he has been staying in the laboratory to study radio." ”

Tesla nodded, smiling with confidence: "Last month, Marconi used isoradial transmission signals to transmit the first wireless telegraphy in the United Kingdom and Australia, but what he didn't know was that we not only have mature research results in this technology, but also carry out short-wave communication simultaneously, and we seem to have more advantages in integrated technology." ”

Cheng Nuo looked around, then covered his mouth with a pu fan and whispered: "Not only that, we also conduct research on coaxial cables, and there is some progress at present, it can be said that they have, we are not bad, we have, they are lacking, such as Popov's application in the signal transmission of naval ships." ”

Shi Jin immediately said excitedly after hearing this: "This is great, with more advanced technology, I believe that the Beiyang government will never be blind to this extent." ”

Wu Yulin was a little worried: "The problem now is that the initiative is not in our hands, when our technical advantage is not stretched to a certain extent, these people will most likely still choose foreign goods, and the more expensive it seems to be worth looking forward to." ”

Hearing this, Cheng Nuo still said calmly: "So we need to muddy the water, so that we have a chance to make a move, not to mention that this time we are not using a photo of the Academy of Sciences, but the United States Fuxing Foreign Company." ”

"Fuxing Foreign Company? What does that mean? ”

Cheng Nuo smiled slightly and explained: "Of course, it is a foreign company under the Chinese Academy of Sciences of the United States of America, and the legal representative, Mr. Nikola Tesla, this statement is very reasonable, right?" ”

"Reasonable, that's very reasonable." Wu Yulin instantly understood what was going on, and clapped his hands again and again: "We should have done this a long time ago, with this layer of foreign skin, I don't dare to be too presumptuous with these moths." ”

"So what's going to happen now?"

"Of course, I took our boss, Mr. Tesla, to the banquet of the chief of agriculture and commerce!"
