Back to the Republic of China to be a editor

The German engineer named Hans pulled a stool. This 40-year-old brother is watching quietly with a group of Tang Hua using tweezers and welding guns to modify the circuit. Look up and chat with Hans while doing it.

"Mr. Tang, are these small particles also diodes and triodes?"

Tang Hua nodded, "This is also called a solid semiconductor device, and its function is the same as those of vacuum glass tubes. As a solid device, its reliability and working life are much longer than vacuum tubes. What kind of work did you do when you were in Sapphire?"

"I...well, research and improve vacuum tubes."

Hans smiled awkwardly.

"Technological revolutions sometimes involve continuous repair and improvement of the previous generation of products, and qualitative changes occur after the performance is gradually improved, which is defined as intergenerational progress; but sometimes, intergenerational progress cannot be continuously improved in the direction of the previous generation of products. But to achieve it, we must find a new way, adopt brand new technology and new direction.” Tang Hua saw that Hans was a little embarrassed, and added, “In World War II, the cross-generation of some German technical equipment was realized by finding a new way. Yes, such as jet engines instead of propeller engines. If German engineers had been confined to the road of continuous improvement of piston engines, the Me-262 would never have been born."

"However, which weapons can be changed through quantitative changes to bring about qualitative changes across generations, and which weapons must find a new way?" Hans asked.

"Weapons? It's better to say they are products. Germany has no relationship with weapons." Tang Hua knows that neither East Germany nor West Germany has an army. "Which ones use the continuous improvement method and which ones need to find a new way, rely on intuition."

Tang Hua pointed to his head.

……

Pacific Ocean, Ennewetak Island.

During World War II, the United States seized the island, which they considered "no man's land."Now the island is clean, there are no aborigines or fishing port villages, only simple roads, various machinery and equipment, and military tents.

The island is now run by the United States Marine Corps, and a company of engineers is working on the center of the island.A large number of steel components and building materials were unloaded from the simple wharf, and the engineering soldiers transported these goods to the central construction site by truck, starting from the foundation for reinforcement, and gradually building up.In the sea around the island, although there will never be any Soviet navy or naval ships from any red country visiting this place, the US Navy still sent 4 warships to patrol nearby in turn.

With the efforts of the engineering vehicles, a huge steel structure tower gradually stood up at the central construction site.The design height of this tower is 66 meters, and a 62-ton weight should be placed on its top. In addition, there are more than 10 tons of other instruments to be hung on several steel beams from the top of the tower to the bottom of the tower.

San Diego Naval Base, Stanislav Ulam and Edward Teller on the top floor of a small building overlooking the entire Naval Base, overlooking the Naval Base.Both of their eyes focused on a transport ship moored at the pier 400 meters away.The heavily guarded pier was bleak, only the sound of the engine of a slowly approaching truck.The guide made the truck stop at the designated location, and the large crane hoisted an eggshell-shaped component on the truck onto the transport ship.

"This is the real power of the sun. The atomic bomb is not." Edward Taylor said in a confident voice when he saw the prototype of the weapon he designed was shipped to the test site.

"I hope our models are right, and our calculations are right. Even so, Taylor, I think your numerical assessment of the hydrogen bomb model is too optimistic."

Taylor focused on the research of nuclear physics, while Ulam's strength was in mathematical modeling. He himself was a well-known mathematician very early on.

In 1949, the Soviet Union’s first atomic bomb exploded successfully, and the United States lost its nuclear monopoly. In desperation, the hydrogen bomb project that had been developed at a leisurely pace suddenly accelerated. In the past two years, Ulam and Taylor were the leaders of the hydrogen bomb project. Two souls.At the Los Amos Laboratory, the two had a flash of inspiration and finally worked out the first credible nuclear fusion model. When the calculation of fusion material data was not sufficient, the U.S. Air Force ordered the manufacture of The first prototype of the hydrogen bomb was developed and it was about to be sent to Enniwetok Island for testing, the operation code-named "Greenhouse Operation".

"The calculation of the fusion energy of deuterium is not controversial, only the calculation of the reaction rate has some errors, or several possibilities." Taylor said, "I insist that the equivalent of 'George' is 30 tons."

"My opinion is that the equivalent will be close to 20 tons," Ulam said.

Moscow.

As the days passed, there were not many people in the demo of the control room. This control room has now been dismantled by Tang Hua, and the operators do not use it anymore. The chief engineer of the "Golden Eagle" project comes here sometimes. The chief designer of the fire control system has never seen it from the beginning to the end. The deputy chief designer——was stationed here from the beginning, and now he chats with Tang Hua every day. Hans.

"I want to ask, why is this circuit designed like this?" Hans, who studies vacuum tubes, is certainly not a zero-based person. He has also begun to understand the design of analog-to-digital converters these days.

"This..." This part of the circuit was not built by Tang Hua here, but was completed before it was shipped to Moscow, but it is not difficult to understand. "Here 12 transistors form a group, and the meaning of forming a group is ... when any one of these 12 transistors fails, the function realized by this group is not affected."

"The design is redundant." Hans nodded to show that he understood. "Setting several semiconductor devices in the circuit as fault redundancy will greatly extend the trouble-free running time of the entire system."

Hans lowered his head and thought for a while, then raised his head again, and said solemnly to Tang Hua:

"So, you China has successfully developed anti-aircraft missiles long ago?"

Chapter 125, Revisiting Kapustin Yar

"So, you China has successfully developed anti-aircraft missiles long ago?"

...I am most afraid that the air will suddenly fall into silence.

Tang Hua couldn't answer this question for a while.

Hans Engineer's deduction is not 100% infallible.That's right, the design of the analog-to-digital conversion circuit made of transistors is very mature, and it's not like the first time to make this type of machine.But it is also possible that China has gained experience in this area while making other types of computers or electronic computing devices.Besides, the analog-to-digital conversion device is not the whole of the air defense missile system.

But Hans guessed right by intuition.

"Do you think the Chinese can develop the most advanced weapons and equipment?" Tang Hua asked an unrelated question without answering Hans directly.

"It's entirely possible."

"It seems that you don't quite accept the theories that Hitler instilled in the Germans."

"Not every German is keen to follow Hitler. For example, like me, I have only cared about my salary, house and wife every day for more than ten years." Hans said, "Oh, and work."

It's ok, although it's German, but not so much racism, that's okay.

"China has already successfully researched anti-aircraft missiles, um, very good," Tang Hua said, "Then what are you and I doing here?"

"Developing an anti-aircraft missile." Hans said without changing his expression, "I think you are developing a missile for the Soviet Union that is close to the Chinese version in performance, but slightly inferior."

Tang Hua smiled helplessly, and the German chatted in a strange direction again. The S-25 is really not a missile that is "better than Chinese air defense missiles".

……

Time moved forward again, and now the customized version of the vector machine and the analog-to-digital conversion circuit have passed the test, and the control room demo2.0 is almost ready to be used again.

And the time has come to New Year's Eve in 1951, February 2th.After all, the second battle has already begun a long time ago.According to the information seen before leaving, the final strategy of the Volunteer Army is to continue to fight back while retreating.The only difference is that the front line of the fourth battle was divided into three groups of troops: Han Group, Deng Group and Kim Group of North Korea. Now Deng Hua is the second chief of staff of the Volunteer Army at the 5 Center, so the fourth battle Our side has become the Han Group, Ye Group, and Jin Group.

The strength of the army is also slightly different. The Han Group has an extra reserve team of the 39th Army. Ye Ting assigned an army to the Han Group as a reserve team to guard the Han River area, but at the same time, he also received 9 troops from the 5th Corps who rushed to the front line after defeating Changjin Lake. teacher.King Group and history haven't changed much.

However, the supply problem of the Volunteers and the combat fatigue problem have not improved much.Originally, a 40 rocket launcher was prepared with 2 ammunition transporters, each of whom could carry 6 rockets.In fact, when several armies fighting on the front line did not fill up all 14 rockets in a group, Tang Hua saw a telegram in January, saying that the ammunition transporters generally picked up the Garand or M1 carbines of the US military, anyway. If your back is not full of rockets, it is better to carry a gun and follow along, and you can hit the enemy twice.

Fatigue problems led the chairman to make a decision in January that he would take three rounds of rest in the North Korean war, and began to form a second round of rotating corps in the country.Now the Volunteers can almost only march or fight at night, hide and camp during the day, and basically find no safe houses in the villages and towns during the day camp, and just dig a nest in the snow to sleep. If the sleeping bags were not provided in advance, the number of patients may be even more much.By the end of January, after Li Qiwei figured out the rules of the Volunteer Army's moonlight attack and 1-1 day week offensive, many front-line Volunteer Army units could not sleep a wink during the day, and the U.S. military would drive tanks and armored vehicles to make tentative attacks during the day.

Before the Spring Festival, the embassy in the Soviet Union also held some social activities. Seeing that Tang Hua was not free, Ambassador Wang came to look for Tang Hua, and was stopped by the guards of the Third Special Bureau without any suspense.

"It may be difficult for us to participate in the quarterly meeting of the Economic and Trade Commission, and we may not be able to attend the meeting," Ambassador Wang said. "I hope we can go to the next round of meetings in June or July."

"We don't want to be restricted by the rules and regulations of the China Economic and Trade Association, but also want to do trade. It's normal for them not to accept it for a while," Tang Hua said, "wait for a while, and continue to contact and negotiate from time to time, so that they can adapt slowly. In fact, we can Finalize some bilateral trade deals with East Germany first."

The Soviet Union accounted for [-]% of the trade volume in the Economic and Trade Council, East Germany accounted for [-]%, and the other six or seven countries added up to a total of [-]%.

"I heard people from the Ministry of Foreign Affairs say," Ambassador Wang also recalled the incident, "We haven't approached East Germany before, but East Germany came to our door first. They wanted to buy computers."

"Haha, good thing." Tang Hua was also happy, "They don't want to order T50, do they?"

"The Germans are well informed. They want four T51s."

I chatted with Ambassador Wang outside for a while, mainly about business matters.By February 2th, East Germany had ordered 5 T4s, and the Soviet Union also had several new orders. The total number of orders in January was 51.But what makes Tang Hua depressed is that there is no order for the imitation Shure 1 microphone.

On the one hand, this is due to the Soviet Union's import control and cumbersome and complicated application process, and on the other hand, the release time of the microphone/T51 computer was not coincident. January 1th is the Russian New Year. In fact, a small batch of samples should be sent over earlier, and a few microphones for the Alexander Red Flag Song and Dance Troupe. If they speak crisply on stage, the publicity effect will be full.

……

The third special bureau, the tests that can be done in the control room have been completed. There is a radar in the design bureau for testing. The analog-to-digital conversion, the fire control computer brushing work, and the output of various signal streams with paper bags, anyway, Tang Hua saw that there was no problem, and the aviation experts and aerodynamic experts of the Third Special Bureau also thought it was very good.
