"Baotou Steel's current initial positioning is steel for railways. In the future, it will also produce armor steel for the second tank and armored vehicle base. But now the construction of nuclear industry facilities in Northwest China may also rely on Baotou Steel."

On the train, Tang Hua said to Qian Sanqiang.

Qian Sanqiang: "Is the nuclear reactor given by the Soviet Union located in Baotou?"

"No, I plan to put this test nuclear reactor around Beijing, mainly for nuclear research. But we will build one or two plutonium production reactors, which will have to be placed somewhere in the northwest. As a reactor, cooling requires a lot of water, It is best to be close to the sea or a river with a large runoff. The sea is not considered for the time being, so we can only look at the Yellow River.”

Qian Sanqiang and Tang Hua looked at the map together.

"The vicinity of Baotou is an option, but in the future Baotou may develop into a large industrial city. ... Looking at the upstream, Wuliangsuhai is not considered, where missiles fly all day long. Further upstream is Bayannaoer. Upstream of Bayannaoer There is Wuhai, then Yinchuan,...Lanzhou." Tang Hua finally saw Lanzhou.

The water volume of the Yellow River in Lanzhou is actually relatively small, after all, it is in the upper reaches.

At the beginning, Lanzhou became a city of nuclear industry mainly because it was located in the hinterland, far enough away from the United States (coastline) and the Soviet Union.

"Lanzhou is in the hinterland of China, and the safety is very good. It's just... far away from Baotou." Qian Sanqiang said, "Bayannaoer is actually not bad, what do you think?"

Bayannaoer is a city with a small population, about 200 kilometers west of Baotou, by the Yellow River.

The disadvantage is a large plain, very close to Mongolia.

Closer to Mongolia is closer to the Soviet Union...

But in 1954, would the central government consider this factor?

If you choose Lanzhou, the nuclear industry will be in an absolutely safe area, but the operating costs will be slightly higher.

"If Lanzhou is chosen, then Xi'an, not Baotou, should support Lanzhou's nuclear industry facilities." Tang Hua said, "If you choose Bayannaoer, then Baotou will complete the industrial support. However, the nuclear industry facilities do not need to be concentrated in one city." Here, I prefer Lanzhou and Baotou to each take part."

"The cyclotron accelerator is located in Tsinghua University, and the reactor is controlled by the Institute of Modern Physics and located around Beijing. In fact, it is still too early to talk about nuclear industry facilities." The chief accountant interrupted.

Thinking about it, the two things I got from the Soviet Union this time seem to have nothing to do with the Northwest.

But it’s not entirely true. This time, two sets of hydrogen fluoride production equipment were imported from the Soviet Union, and they were handed over to the Bureau of Chemical Industry to set up two factories.One of them is in the Northeast - the fiber optic factory uses hydrogen fluoride.The other is to be placed in Baotou, where fluorine resources are too rich.

The hydrogen fluoride plant in Baotou is of course used to process yellow cake into UF[-].The UF[-] is then sent to a gas diffusion plant for isotope separation.

"If we determine the city where the nuclear industry facilities are located as soon as possible, we can arrange the electricity and transportation here in advance," Tang Hua said. "Most of the nuclear industry is a big power consumer, especially the gas diffusion plant. One plant will eat up one. The power generation capacity of a 30-kilowatt thermal power station. But now only the gas diffusion method is the only feasible isotope separation method.”

Shanghai, Ship Industry Bureau Shanghai Ship Research Institute.

"When will Minister Tang come back from the Soviet Union?" Cheng Wang, director of the Shipbuilding Industry Bureau, asked the secretary of the research institute in a low voice.

"Minister Tang and Vice Premier Chen should be on their way back to China right now?" The secretary said uncertainly, "But the journey should take more than ten days. Besides, Minister Tang may not come to Shanghai immediately after returning to Beijing." ah."

Cheng Wang: "This is very difficult. The two foreigners have different opinions and have been in a stalemate for several days. Only when Minister Tang comes back can they be settled."

"The displacement of a warship is a number determined after comprehensive consideration of all aspects. It is actually unwise to increase the displacement meaninglessly and increase the cost."

Zubov, Deputy Minister of Shipbuilding Industry of the Soviet Union and Chairman of the Committee in China, shook his head.

"The high-speed ship type of the Type 56 destroyer was not very meaningful in the 50s. In order to achieve high speed, it sacrificed too much in other aspects, especially the interior layout of the ship. It is time to reverse this wrong design idea. .”

There are only 2 people in the small conference room. Besides Zubov, the other is Shigeru Makino, a ship designer who came to China from Japan to work on "Shangpiao".

Zuboff: "Increasing the speed of a warship...whether it is offensive or defensive, there is always some benefit. Especially this is a destroyer."

Makino Shigeru: "I have only been in China for 8 months, but during these 8 months, I have updated my knowledge system. ... The high speed requirements of destroyers originated from the era when artillery and torpedoes were the main weapons. Artillery far The distance accuracy is low. In order to expel or destroy the enemy torpedo boats as soon as possible, the destroyer needs to approach the torpedo boats at high speed to speed up the speed of destroying them. When the torpedo attack, the destroyer needs to seize a favorable launch position at high speed, so that the torpedo appears at the earliest position of the enemy formation. Uncomfortable angle. And I have carefully studied the emerging anti-ship missiles in the past few months. From the minimum launchable range to the maximum range of the missile, there is no obvious difference in hit rate. This means that destroyers will not need to do it in the future Tactical maneuvers at extreme speeds can attack surface targets in a wide range."

Makino Shigeru paused, and then said: "Even the destroyer itself may become the capital ship of the navy's surface combat ships instead of the auxiliary warship, the premise is that the destroyer must increase its endurance and stability to facilitate ocean-going navigation. In my opinion, 56 If the hull of the Type Destroyer is widened based on the existing design, even if the maximum speed is reduced from 36 knots to about 30 knots, it will not have too much negative impact on its operations, but the carrying capacity of fuel and fresh water can be significantly reduced. Increase."

Chapter 37, Finite Elements

"A tanker train."

"Another tanker train."

"It's still a line of tank trucks. Look at the shape of the tanks. This line is not crude oil, but refined oil."

The delegation's train is still an express train, which is faster than ordinary passenger trains and faster than freight trains.When the train passed Irkutsk, Ulan-Ude, and was about to enter China, Tang Hua saw freight trains stopped at small roadside stations being overtaken from time to time along the way, among which the most varied were tanker trucks.

Chief accountant: "It's not oil, it's all foreign exchange."

Tang Hua, Qian Sanqiang: ...

"The mood suddenly fell to the bottom" is the feeling now.

In 1953, China produced 63.6 tons of oil for the whole year.Imported petroleum and refined oil totaled 105 million tons.This is because the level of industrialization is not high, and the country has tried every means to save oil consumption by substituting oil, so it imports 100 million tons of oil every year.

Although diesel locomotives are now very mature, and the Soviet Union also has mature production lines, steam locomotives run on more than 2 kilometers of railway lines.There are very few cars, and most of the buses use gas instead of gasoline and diesel, and they all carry a bulging gas bag on their backs.

In 1954, oil imports should have been at the level of just over one million tons. Since 1955, with the sprint of the First Five-Year Plan and the acceptance of 156 projects in batches, oil consumption could not be suppressed no matter what.Historically, oil imports rose to 1955 million tons in 160, reached 1960 million tons in 300, and then began to gradually shrink.

Tang Hua felt that it was necessary to use foreign exchange to buy machines and equipment, to buy some difficult parts, and to buy weapons with foreign exchange in previous wars.But oil...he bought it to burn it. This year he bought more than 100 million tons and burned it. Next year he will buy more than 100 million tons and still burn it.

In the early days of industrialization, in the era of tight foreign exchange, the lack of resources was really uncomfortable.

At present, China's label of "oil-poor country" has not been taken off, only a few small oil fields are being exploited, and there is also artificial oil-oil refining, which is a super-costly way to obtain oil.In 1953, Yumen Oilfield produced 42 tons of oil, including 20 tons of liquid oil and 22 tons of oil from oil mines.The craziest year in Yumen was 1958, when 140 million tons of oil were produced, of which 24 tons were extracted from liquid oil, and the other 116 million tons were all produced from oil mines.

"Zhang Jue, the software team of the Institute of Computer Science needs a team of about seven or eight people to input the data in these papers into the computer system and store them. Simple input work does not require senior programmers, but the operator must have an engineering background Base."

Tang Hua took out a bunch of papers and materials.Mainly belonged to Li Siguang and Huang Jiqing.

"China's tectonic divisions: Cathaysia tectonic domain, Yangtze-Qiangtang tectonic domain, Tibet-Myanmar tectonic domain, Pacific Rim tectonic domain, Sino-Korean tectonic domain/Sino-Korean platform, Tarim tectonic domain, Altai-Xing'an belt... Minister Tang , how high is the numerical precision of these constructed domains?"

Tang Hua estimated that the division accuracy of China's terrestrial structure in these papers does not seem to be very high. "You can input all the numbers mentioned in the paper as much as possible. Some of these geological exploration work are detailed and some are rough. The accuracy of rough papers is not high, so we don't want to reduce the accuracy."

"The two of you are responsible for the geological structure, and this latest report is the most accurate. If the report of a slightly older paper conflicts with this report, the latest report shall prevail."

What Tang Hua held in his hand was the report "Looking at my country's Petroleum Exploration Prospects from the Earth Tectonics" published by Li Siguang in January this year.

From January to June 1953, Li Siguang explored uranium mines in Fuzhou, Jiangxi, and then went all out to conduct geological exploration throughout Jiangxi.This completes the key data of the last part of the model he proposed in the past.

The New Huaxia Structural System, also known as the New Huaxia System.

Li Siguang established a mathematical model for the giant polymorphic tectonic system formed since the Mesozoic in eastern my country.The model shows that the eastern part of my country is composed of a series of large-scale uplift and subsidence zones, accompanied by torsional and tensional faults.In the latest report, Li Siguang divided the east into three uplift zones and three subsidence zones.

The first uplift zone refers to Taiwan, Japan Islands, Ryukyu Islands, and the Philippines, and the first subsidence zone refers to the Yellow Sea, East China Sea, South China Sea and continental shelf.

The second uplift belt extends from Zhangguangcai Mountains, Changbai Mountains, Liaodong Peninsula, south to Jiaodong Peninsula, and Wuyi Mountains in the southeast.The second subsidence zone is the Songliao Plain, the North China Plain, the Jianghan Plain, and the Bohai Sea.From January to June of 53, Li Siguang mainly worked out the geological data of the second uplift belt from the Jiaodong Peninsula to the Wuyi Mountains.

The third uplift belt extends from Daxing'an Mountains and Taihang Mountains to western Hunan and eastern Guizhou.The third subsidence zone is mainly the two basins of Ordos and Sichuan.
