Siheyuan: I, Silly Zhu, Start with Divine Medical Skills

　　Researcher Deng Chunfa, who was in charge of researching the new receiver, was annoyed when he saw that the radio was assembled and placed in its original position:

　　"That guy messed with my stuff, doesn't he know how troublesome it is to disassemble and assemble the receiver? It interrupted our design and transformation ideas, and maybe even damaged our stuff, who will pay for it!"

　　After venting, Deng Chun found that the power was turned on and the antenna was set up, so he just pressed the red power switch in.

　　I saw a clear and loud voice coming from the speaker of the receiver:

　　"ThisisVoiceOfAmerca..."

　　A burst of English broadcast voices came out, which directly startled Deng Chunfa!

　　What's going on here, how can there be a broadcast of "The Voice of the Ugly Nation"!

　　In fact, there were many boat activities along the coast at that time, broadcasting various broadcasts day and night.

　　Deng Chunfa can speak English, because he studies communication equipment, and he has to learn English.

　　Deng Chunfa was excited, looked at the other knobs, and tested it.

　　It was found that not only the voice of the ugly country, but also the weather report of the ugly army in Guam in the Pacific Ocean can be received!

　　Deng Chunfa determined that this receiver can be used to listen to long-distance short-wave radio stations, and can receive clear and stable international radio stations such as Voice of the Ugly Kingdom and ABC.Excellent performance and super anti-interference, you can also listen to unilateral maritime communication radio!

　　Deng Chunfa quickly and carefully disassembled the receiver.

　　He found that the circuit and circuit here have been transformed!Transistors are also a little different, a result of He Yuzhu's micro-shaping capabilities.

　　First of all, the reformer reduces the power dissipation of the collector plate and optimizes the transformation of the transistor.

　　Then enhance the maximum allowable DC current of the electrode, so that the radio can withstand greater current power.

　　Then increase the breakdown voltage, and the replaced transistor can safely withstand the working voltage of up to 220V;

　　Finally, the frequency characteristics are adjusted!

　　Almost all circuits have been shielded against interference!

　　In fact, this short-wave receiver was invented in the 70s, and it was an extension of this prototype as the goal of improvement. He Yuzhu just did this in advance.

　　But this kind of progress is undoubtedly another inspiration for the existing scientific and technological R&D personnel, especially the result of the development towards miniaturization and integration, which is in front of us!

　　Deng Chunfa immediately became anxious, and directly grabbed another researcher who came to the staff lounge and asked:

　　"Who just got my radio?"

Chapter 43 Silly Zhu returned, and the researcher who was asked about the special car treatment directly shook his head.

　　Deng Chunfa even asked several people, but they all said they didn't know!

　　Deng Chunfa did not dare to delay, so he directly found Director Qian and made a report:

　　"Director Qian, I have a major discovery to report to you!"

　　Director Qian had just sent He Yuzhu away, thinking about when to go to He Yuzhu's for treatment. When Deng Chun sent a report to report the problem, he put his mind away and asked:

　　"what's the situation?"

　　Deng Chunfa: "Our radio station has been modified into an ultra-long-range transceiver, which can receive radio signals from far and far away!"

　　Director Qian didn't take it seriously, he waved his hand and said, "Understood, you must have made a high-power receiver again!"

　　Deng Chunfa hurriedly explained: "No, I didn't make it, and this is a small receiver with only 110W of power!"

　　"what!"

　　Director Qian stood up in shock. What he was surprised was not the long-distance receiver, but the 60W (watt) power!

　　What would it mean if low-power ultra-long-range receivers were available?

　　First of all, your own radio can send and receive signals at low power, reducing the risk of exposure.

　　Secondly, the use time of the radio can be greatly extended, which can ensure the combat command time.

　　Finally, if this technology can be applied to long-distance broadcast communication?

　　Director Qian couldn't sit still. This was a serious matter, so he rushed to the scene immediately.

　　I saw that the receiver was reopened, and the circuit boards and transistors inside were obviously modified. The total volume was only two-thirds of the original size. The circuit layout was more scientific and tighter, giving people an industrial aesthetic.

　　After various tests, I was surprised to find that this receiver has strong anti-interference ability, low power consumption, light weight, and anti-vibration!

　　Remember that radios from the 60s had a hard time picking up radio signals clearly on bumpy roads!

　　Director Qian, as one of the few technical talents in China who has contact with transistors, can see the difference of this transistor at a glance!

　　The transistors introduced in the [-]s are all diodes, and the structure is simple to understand at a glance, and this transformed transistor inputs a weak signal between the emitter and the base, and the output between the collector and the base, Just amplify it into a strong signal, and use a "rectifier junction" to replace the metal semiconductor contact. What kind of transistor is this?

　　Deng Chunfa dismantled the transistor and tested it separately. He found that the transistor can amplify the audio signal by 100 times, with low noise, can still be controlled when the power is increased, and has a very wide range of applications!

　　What would happen if you put this transistor on your own satellite radio transmitter?

　　That can greatly reduce the power required by the broadcast signal transmitter, prolong the battery life of the satellite, and maybe even realize the direct-to-ground broadcast of the satellite!

　　Director Qian was excited: "We must find this talent!"

　　Researcher Deng Chunfa: "Director, you must help me find him. I believe that with his participation, I will only need one month, no, ten days, and I will be able to figure out the design of this transistor!"

　　Director Qian directly asked everyone to broadcast, and broadcast it three times in a row, but no one came forward and admitted that he did it by himself!

　　So Lin Lao said, under the reward, there must be a brave man!

　　So all kinds of promotions, subsidies, salary increases, benefits, and holidays were broadcast, but no one came out to admit it!

　　Then this became a mystery for the time being.

　　However, the emergence of short-wave two-band receivers has also directly accelerated the research on transistors, as well as the research on the miniaturization of national radio stations and radios!

　　"Ding! Congratulations to the host, the country has greatly accelerated the research on the miniaturization of transistors, radio stations and radios, and obtained 200 points of reversal value!

　　The current reversal level value is 2125/2000, the remaining reversal value is 1325 points, and the system is upgraded! "

　　"Congratulations to the host for obtaining: Mixed Martial Arts Mastery: The host is proficient and masters various fighting skills!"

　　Immediately, He Yuzhu's mind kept pouring into a large number of fighting related experiences and memories, including Sanda wrestling, karate, judo, taekwondo, kickboxing, Brazilian Gracie Jiu-Jitsu and more!

　　He Yuzhu feels that his body has a lot of muscle memory. He can follow the ups and downs of the vehicle to adjust the resonance range of his body. He can control his hands and feet to do some very fine movements, and he can attack or defend at any time!

　　He Yuzhu wanted to shout now: "I want to hit ten!"

　　But he held back, because now he was going to return to the courtyard, and he had to go home to digest the information.

　　Tang Weimin drove the car and enjoyed the feeling of speeding, and returned to the Siheyuan alley in just [-] minutes.

　　A car is a rarity, let alone a jeep with a military badge.

　　As the jeep drove into the alley, a string of children followed behind the car's butt.

　　The child followed, shouting, "Look at the car! Look at the car!"

　　People nearby came out one after another to see what was going on, and some were knowledgeable.

　　"This, this is the army's jeep, you see, the green body, and the military license plate!"

　　The third master lives in the front yard and heard the shouting, is there a car coming?

　　"This is really an army car! It's really stylish!"

　　"It must be a leader who cares for our people!"

　　People were talking and looking forward to seeing what kind of character would come out of this car.

　　The third master heard the noise outside the door and went out to take a look.

　　Look, Jeep!

　　The jeep had to honk the horn because it wanted to remind the onlookers in front of the children to walk away. As a result, everyone in the courtyard was alarmed, and they stepped out of the gate to see which big leader came to the courtyard.

　　Everyone saw the door open!A person walked out from the back door of the car. It was Section Chief Du Xifeng, the security department of the rolling mill!

　　Everyone felt that the person who was going to dispatch the chief of the security section was definitely not a small person.

　　Then the main driver's door opened, and Tang Weimin in an officer's uniform came down!

　　The knowledgeable person looked at the epaulette and exclaimed, "It's an officer!"

　　Everyone took a deep breath!In such a battle, it is not certain which high-level person came.

　　The first master and the second master were already standing side by side at the entrance of the middle courtyard.

　　Qin Huairu, who was physically and mentally exhausted after a busy day, also came out, wanting to see if the leaders came to the grassroots to inspect, maybe she could show her face, and it would be good to shake hands in case.

　　The cars she has ridden in her life are the minibuses from the village to the city, and the buses.

　　Under the expectation of everyone, the door of the back seat was opened, and a pair of shiny leather shoes stepped out first, and then a straight tunic suit was revealed.

　　Everyone was short of breath and their hands were sweating.

　　This person completely appeared, and everyone looked at it, stunned, stunned, and shocked!

　　Isn't this stupid?

Chapter 44 The second uncle, who couldn't help but watch with curiosity, was also dumbfounded.

　　Qin Huairu looked at He Yuzhu who got off the jeep and covered her mouth in surprise!

　　The first master and the second master were both surprised.

　　The uncle was surprised that He Yuzhu was so developed that there were cars to pick him up.

　　The second uncle's attention was more on Du Xifeng.

　　As the second uncle of the official fan, he can recite all the cadres in the rolling mill, and he has also put a lot of hard work in identifying people.

　　Therefore, he recognized Du Xifeng at a glance now, so he quickly stepped forward to hold the hand of Section Chief Du and said excitedly.

　　"Senior Du, why are you here?"

　　Du Xifeng was stunned, who is this?actually know myself.

　　"Who are you?"

　　"Senior Du! I'm Liu Haizhong, the seventh-level fitter in the third workshop, the second uncle in this yard. If you need to know anything, just ask me!"

　　The second uncle saw He Yuzhu also got out of the car, and he was so angry that he didn't get out of the car. Usually, the leader got out of the car last.
