Back to the Republic of China to be a editor

What Tang Hua was looking at was the feedback and comparison report of several submachine guns used by volunteers training in North Korea and in the Northeast.

During the same period, the British Stern, the Soviet Union PPSH41, PPS43, the American-made M1 "Thomson" and the seized American-made original M3 were compared.

The original M3/Taiyuan imitation M3 was tested in the first-line troops and scored the highest. Now the troops strongly appeal to install Taiyuan M3.

Bobosha 41 and PPS43 actually lost to M3? !Or Taiyuan imitation M3?

But a closer look at the report shows that the trial troops are very serious, and the evaluation and feedback are all signed by the commanders and fighters.The words that appear many times are "M3 is powerful!" "M3 is very powerful" "M3 bullets hit people very hard!"

It seems that they are all the opinions of volunteer soldiers who used the M3 they picked up to fight on the Korean battlefield.As for the heavy weight of the M3, there are not many opinions from volunteer soldiers.

Look at the results of Taiyuan imitation M1911A1, which is also one of the best two guns, with a higher score than Tokarev TT33.Volunteer Army commanders and fighters commented not only on "great power", but also "this gun looks better than TT33".

如果确定将太原仿M3作为制式装备，那制式手枪肯定也要选M1911A1，这俩枪的弹药是一样的。同理如果冲锋枪选了PPSH41或PPS43，那手枪也得是TT33。

In the future, the AK47 will be imitated and introduced, and the submachine guns with pistol cartridges will definitely be withdrawn from the front-line combat troops and become self-defense weapons for the auto corps, artillery, armored soldiers, special forces weapons, and public security army weapons.When used for these purposes, it is actually better to have a lighter submachine gun.But the stopping action of the 11.43mm bullet is addictive.In addition, although the M3 is heavy, the folding holder design makes it more convenient to carry than the PPSH41.

唐华现在是稍微有点犹豫。M3/M1911A1在一线部队口碑最好；兵工总局刘鼐表示同意大批量生产M3/M1911A1；如果唐华再把自己的名字签上去，送到装备部门那里，M3和M1911A1可就要成为解-放-军的制式冲锋枪和手枪啦。

"Liu Nai: This is feasible. M3 and M1911A1 are the most highly rated among front-line commanders and fighters. We should seek truth from facts and choose weapon models that have been tested in practice. There are a large amount of submachine guns and pistols. Self-manufacturing can save a lot of money when our army uniformly changes equipment. Foreign exchange, this matter should be done sooner rather than later. After the refitting work is decided, we should communicate and coordinate with the Soviet Union, but we should stick to our own choice. In addition: most of the American-made weapon parts are relatively fine, and the quality of materials and processing techniques must be strictly controlled , continue to maintain high-quality manufacturing, please remind the Taiyuan Factory to pay attention to this point from the General Administration of Ordnance Industry. Tang”

After the approval document is issued, the Type 50 submachine gun and the Type 54 "Big Black Star" in Lei Feng's photo will be completely changed. It's exciting to think about it.

其实冲锋枪和手枪这两型轻武器是小场面，太原厂仿制的12.7毫米M2重机枪才是刘鼐和唐华讨论决定的重点项目，仿制M3和M1911A1其实是让太原厂的设计和制造团队练手。

"Mr. Hou, it's almost New Year's Eve and you still come to Shanghai from Sichuan in person."

Not only official documents were sent, but also living people came - Hou Debang went straight to Shanghai from the Yongli branch factory in Zigong, Sichuan.

Hou Debang: "This time I came to Shanghai, I want to ask you a question, and then order some mechanical parts for the Yongli branch in Shanghai... Minister Tang, if we now have very close trade ties with the Soviet Union, then Can the Bureau of Chemical Industry apply for the introduction of another synthetic ammonia production line? I want to practice my joint soda production method in Tianjin, using the imported synthetic ammonia production line plus my soda production equipment."

Tang Hua: "The Soviet Union can provide us with ammonia synthesis equipment at any time, as long as there is a loan line or...we will raise foreign exchange to pay for the goods. But—Mr. Hou, how should I say it? I think the Solvay method is also very good."

Hou Debang: ? ? ?

In 1939, Hou Debang invented the combined soda-making method (also known as Hou's soda-making method), which made the world's soda-making technology break through again after the Solvay method.

The raw materials of the Solvay process are quicklime and salt (sodium chloride), and the products are soda ash and calcium chloride.Ammonia is required in the production process, but it is basically not consumed by recycling.

The raw materials of the combined soda making method are carbon and salt, and the products are soda ash and ammonium chloride.To put it bluntly, it is a set of carbonization ammonia synthesis equipment combined with a set of soda production equipment developed by Hou Debang, so it is called the combined soda production method.

The advantage of the joint soda production method is that the utilization rate of sodium chloride is extremely high, and the second is that besides soda ash, the other product is ammonium chloride, which can be used as a fertilizer and is much more useful than calcium chloride.

However, during the period of the Republic of China, Hou Debang was unable to build a joint soda production plant in China, and could only complete the proof of principle in the laboratory. In the first half of the 20th century, ammonia synthesis equipment was a high-tech strategic equipment, even among capitalist countries. It can be bought and sold freely, but the Republic of China cannot produce its own synthetic ammonia equipment.It is only now that New China has been established, and hope is rekindled in Hou Debang's heart.

Tang Hua: "First, now that the state has canceled the salt tax, salt is only regarded as a common mining resource, and no additional high taxes are levied. The advantage of the high utilization rate of sodium chloride in the combined soda production method is not as obvious as it was in the Republic of China period. .”

Hou Debang: "Well, the Solvay method is indeed cheaper now than before. But..."

Tang Hua: "Secondly, the combined synthetic ammonia-urea production line we are currently researching will eliminate another advantage of the combined soda production method."

Hou Debang: ? ?

Tang Hua: "Ammonium chloride is no match for urea."

A question mark appeared on Hou Debang's head just now. In fact, he himself was thinking about the answer quickly. After Tang Hua said it, Hou Debang also understood. "Ammonium chloride is slightly lower in nitrogen and also contributes to soil acidification."

Tang Hua: "If we get the synthetic ammonia-urea joint production line in two or three years and can produce urea at low cost, then the by-product ammonium chloride will not be as valuable as before. If you calculate it carefully, it will be simply The Silvey method is easier to implement and lower in cost....Mr. Hou, don't be disappointed. It is our own synthetic ammonia-urea combined production line that overthrew the combined soda production method. The status of the urea production method in the future chemical world is higher than that of the combined soda production method."

Chapter 199, Cube Game

On January 1952, 1, Reuters reporter William Celeste and the photographer, wearing steel helmets and a bulletproof vest over a padded overcoat, left the ruined walls of Yangzhou City and groped north.

Leaving Yangju means leaving the stronghold controlled by the US military.According to the map in hand, 3 kilometers in front of Celeste is a trench controlled by the Chinese army, and 200 meters behind the trench is a dark gray mountain ridge.

In the past month, the Yangju-Dongducheon-Pocheon area has been relatively quiet. This is not because the negotiations between the United Nations Army and the Chinese and North Korean sides in Hwacheon are still going on, but because both parties lack interest in launching an attack in this area.

Celeste and the photographer bowed forward for 400 meters. The photographer felt that they had entered a dangerous area, but Celeste did not stop.Encouraged by him, he and the photographer crawled another 100 meters in the mottled snow, trying to get as close as possible to photograph the mountains occupied by the Chinese army.

"I used 12x binoculars to look at the mountains in the distance, but in the winter blizzard, the mountains did not reveal any details. I couldn't see bunkers, forts, machine guns, or soldiers. There was a The traces of different shades may be a large area of ​​barbed wire, but they may also be the remnants of the battle half a year ago."

"On December 12, I arrived in Yangju—a small town that was the northernmost stronghold of the United Nations forces on the Han River Plain. An infantry regiment of the United States Army was stationed here. To my surprise, here No one was nervous, let alone hysterical. I saw people here—from low-ranking officers to soldiers, everyone’s face was flat, with some depression mixed in. In the steel beams and the huge circle In the anti-gun bunker made of wood and thick sandbags, the soldiers ate on time, slept on time, patrolled, reinforced fortifications, smoked and drank, and occasionally shared a few old driver magazines.”

"My first impression of Yangzhou is that the morale here is neither high nor low, and the soldiers seem to be used to their duty - to hold the position here. However, the battalion commander Sharbo told me: all this is calm Because the United Nations Army did not issue an attack order. He told me worriedly: If the Eighth Army ordered an attack to break the self-deceitful rhythm of life of these people, then the hysteria among soldiers and junior officers would suddenly break out, just like the 8 and 1917 wars. Like the French Army on the Western Front in 1918."

"Six months ago, the largest tank battle since the end of World War II took place here, and it was also the battle with the largest casualties for the US military. The battle was divided into two halves by a negotiation. In the first half, the Chinese army The tanks penetrated the plains of the Han River, captured Seoul and surrounded and wiped out a division of the US Army. In the second half, the US Army launched an attack. Van Fleet used the largest artillery battery in history to support the US and South Korean infantry. The mountains were fought for a full 10 days, and the corpses of the Chinese army and the United Nations army covered the entire hillside and valley. When the American army was exhausted, the Chinese army tanks appeared again and pushed the American army back 20 kilometers, ending the war bloody battle."

"On June 6, three U.S. divisions were repulsed, and the final whistle was blown again. The two sides entered a period of tacit understanding on the Western Front for more than five months. In my opinion, both warring parties hope that this tacit understanding The ceasefire will last forever until the leaders of both sides agree to sign the armistice agreement."

"Captain, can installing this thing make the missile more powerful?"

The Hongqi-62 Missile Regiment of the 1nd Anti-aircraft Artillery Division, the missile launch vehicle is being refitted by the logistics battalion and the Communication Department of the General Staff, and the controller who was idle asked the regiment leader.

"No, but it keeps you from dying."

"The last time the comrades from the communications department came, they installed six tubes of fireworks bombs on the left and right sides of the truck. The comrades from the communications department said that this thing could keep us from dying. Today, they put four iron frames on our truck, and they can still keep us alive." I can't die. Am I going to die so easily?"

"Little comrade, have you heard the saying 'the road is as high as one foot and the devil is as high as one foot'?" The comrades from the communication department stood up from the truck and asked the little soldier to control his hand.

"I know, even if the Taoist becomes stronger, the devil will become stronger after a while."

"It's right to know. We just have to be prepared. When the devil is one foot tall, we can immediately become two feet tall. Do you understand?"

The Shanghai Institute of Computer Science is also celebrating the New Year.The Chinese celebrate the Spring Festival, but the Soviets do not.The Soviets celebrate the Russian New Year, but the Chinese do not.Fortunately, there is also New Year's Day. The Gregorian calendar year is not considered a New Year in the Soviet Union, but it will be commemorated, so the Shanghai Institute of Computer Science will take the New Year's Day to open a small restaurant to relax.

"Now the Shanghai Computer Institute is equipped with diesel emergency generators, and the power plants in Shanghai don't often experience power outages," Tang Hua said. "Last year, the scene where Professor Lebedev carved the operating system with a knife will never happen again. But that It was a really interesting scene…”

"I have corrected it many times. Instead of engraving it with a knife, I used an electromagnet to modify the data of the magnetic ring. Because the electromagnet is small and the wire is very thin, I wrapped the wire around a plastic knife for easy operation."

The five-member team from Ukraine is all here today.Except for Lao Lie, several other people usually work in Zhenjiang, Suzhou, and Yizheng. Although they are not far from Shanghai, it is not easy to get together at the same time.

"Actually, today we should also celebrate the achievements made two days ago," Tang Hua said, "The first prototype of T52 was successfully run."

Lebedev: "I'm not like you. I have to pick the right time node. For example, I plan to run the TC52 supercomputer for the first time on the Russian New Year."

唐华：“这不成问题。12月30日T52首次运行成功，1月1日，T52计算机还有一件很重大的事情。”

Tang Hua got up and went to get the results he had made in the past ten days.

The code he wrote has been stored in a tape. Although it is only a few KB of code, the data is transferred between two computers—and the data is transferred between T51 modified machines of different models and T52. reliable.

Put the tape into the entrance of the tape drive, and the small program is copied to the memory of the T52 computer in an instant.
