Regarding the proposal put forward by the Soviet aviation industry department and Korolev, the central government agrees with the proposal of China and the Soviet Union to jointly develop next-generation satellites, and Tang Hua has no objection, but after the new year, we will send a special telegram to Korolev. The boss is anxious.
"Look, Huaihe."
Zhou Xuan pointed out the window for Tang Hancheng to watch.
On the train from Beijing to Shanghai, a group of people saw the Huaihe River outside the window.It is the dry season when the Huaihe River is like a tame big snake. The water level is not too high, and the water quality becomes very clear.
When the beginning of spring enters the rainy season, the Huaihe River should turn yellow, and the water level will rise sharply...
"The Ministry of Water Resources is digging an artificial river, and in five years' time, the Huaihe River will flow into the sea," Tang Hua said. "At that time, the Huaihe River will be much less likely to flood crops."
Tang Hancheng: "If the Huaihe River did not have so much rain and the runoff did not exceed the standard, there would be no floods."
Well, I'm not yet 7 years old, but I learned a lot of strange knowledge from myself and those uncles.
"That's called artificial weather control. In the future, we will control the weather to a limited extent," Tang Hua said, "for example, let the rain not fall on the Huaihe River, but in other places. However, the most important thing is to know in advance when it will rain. Rain. If we know whether there will be heavy rain in half a month, we can prepare in advance and deal with floods.”
Zhou Xuan: "If you want to know if it will rain in half a month, you have to ask Huang Daxian at the entrance of the village to do the math."
"This person's name is not Huang Daxian, but Zhu Kezhen, Grandpa Zhu. ... We went to Shanghai to figure out how to do fortune-telling. I guess, soon after the Chinese New Year, the Chinese will know when the first rain of this year's rainy season will fall. down."
Chapter 172, 6.4 million times per second!
The No. [-] Iron and Steel Plant of Shanghai Iron and Steel Corporation.
Before liberation, there were 3 iron and steel factories in Shanghai. At the time, Shanghai Iron and Steel had 8 iron and steel factories. Now there are five factories in total, which are Shanghai Iron and Steel Factory No. [-], No. [-], No. [-] and No. [-] and Pudong Iron and Steel Factory (No. [-] Factory). .
Since 1950, the Ministry of Heavy Industry mobilized the whole country to launch key construction projects. First, Anshan Iron and Steel Co. Steel, Maanshan Iron and Steel, and the new Tangshan Iron and Steel Plant that is about to start construction.
You can see that, in fact, from the liberation to the present, Shanghai's steel industry has not received a national key construction project.
However, the annual steel output of the Shanghai Iron and Steel Company was 1951 tons in 30 and 1957 million tons in 200... quietly, Shanghai has become one of the five largest steel bases in the country, and it ranks fourth (Baogang because of No. 3 and the No. 4 blast furnace have not been put into operation, and the annual output is only 150 million tons).
In recent years, the state has only provided technology and talents to Shanghai's iron and steel industry. For example, the General Iron and Steel Research Institute sent people to work on oxygen top-blown converters, and rarely provided financial support.The only state support was the direct purchase of a British (Indian) steel production line in 1955, but just this, after the equipment was bought back, the Shanghai Municipal Government played with it.
In short, the expansion of Shanghai Iron and Steel Company's production capacity mainly relies on its own accumulated profits in addition to Shanghai's finances.
(Wuhan and Baotou are slightly embarrassed)
"As a rich place in the south of the Yangtze River, Shanghai's industrial development has a solid agricultural support, convenient transportation, and a relatively strong tradition of industrial and commercial operations compared to other regions, so our Shanghai Iron and Steel Co., Ltd. can have a relatively smooth and rapid development." Shanghai Iron and Steel Co., Ltd. Factory Manager Ma of the third factory said modestly, but he was quite proud in his words.
Tang Hua: "Industrial and urban construction in the Yangtze River Delta region is developing rapidly, and the demand for steel is increasing year by year. This is also a powerful driving force for the development of Shanghai's steel industry. Your Shanghai Steel No. [-] Plant is driven by the shipbuilding industry. The good news is that Shanghai's shipbuilding industry will continue to grow rapidly in the future."
Not only has the steel output of Shanghai Iron and Steel Company quietly increased to more than 200 million tons, but the quality is also very unusual.The Shanghai Iron and Steel Plant No. 56 that Tang Hua visited now produces marine steel. The materials for Type 3 destroyers No. 4 and No. 01 are produced by Wuhan Iron and Steel. In fact, Shanghai Iron and Steel No. [-] Factory also supplies part; after the localization of Type [-] frigates, most of the steel is produced by Shanghai Iron and Steel No. Too.
Factory Manager Ma: "We also feel it. If the marine steel products grow rapidly, will the No. [-] and No. [-] plants of Shanghai Iron and Steel Group merge in the future?"
Tang Hua: "At present, the No. [-] Shanghai Iron and Steel Plant produces stainless steel, the No. [-] Shanghai Iron and Steel Plant produces high-strength steel wire rope and steel wire, your plant produces marine steel and medium and heavy plates, the Pudong Plant produces various civil carbon steels, and the No. [-] Plant produces special steel. According to the future plan of the Ministry of Heavy Industry, the third factory and the fifth factory are indeed prepared to be merged and expanded."
"Oh! That's another big scene."
Tang Hua: "It is now said that Shanghai has not five steel plants but nine, because the line from Suzhou to Shanghai has opened four national standard small steel plants, all of which are producing at full capacity. Jiangsu-Shanghai needs too much steel Yes. The expansion of the third and fifth factories is not an ordinary expansion, so it may be necessary to choose a place to build a new steel industrial park."
Factory Manager Ma: "Do you want to leave the urban area of Shanghai and go to a place farther away?"
Tang Hua nodded, "The initial location is Baoshan County. Now you can consider what major issues need to be resolved during the merger and relocation."
"The most important problems are caused by the relatively long distance." Director Ma said very straightforwardly.
Leaving Shanghai, for many workers, there may be a problem of declining quality of life.It is not enough for Tang Hua and Director Ma to discuss this issue. They have to hold an on-site meeting with the Shanghai Municipal Government to solve the problem.
……
Ke Qingshi, Secretary of the Shanghai Municipal Party Committee: "Shanghai Iron and Steel's new factory has gone to Baoshan County. How big a steel factory are you going to build?"
Tang Hua: "In 15 years, the annual output of Shanghai Iron and Steel's new plant will be equivalent to the current total steel output in the country, that is, more than [-] million tons."
Master Ke Qing: ...
Tang Hua: "For long-term planning, you have to think about the future development situation in advance. For example, in Shanghai, if you make a 15-year municipal construction plan, you may have to prepare for the population of Shanghai to exceed 1000 million, and it will continue to increase in the future."
Ke Qingshi: "Yes, industrialization must be accompanied by urbanization, and the urban population will account for an increasing proportion of the national population. Baoshan County is relatively remote. If there is a steel city there, the daily consumption of so many people needs to be considered. We will work with industry to coordinate the timing."
Tang Hua: "In addition to the state-owned enterprise-local linkage principle we set before, we also hope that when Shanghai Steel's new plant in Baoshan is put into operation, we will build an express road from Baoshan to downtown Shanghai, and then connect it to a bus line."
Factory Manager Ma: "I think Baoshan County can be changed to Baoshan District. In this way, workers don't feel that they are going to work in the countryside."
Master Ke Qing and Tang Hua: ...
……
The supercomputing hall of the Shanghai Institute of Computer Science is the birthplace of all supercomputers in the world.
Not just a place of design and invention, but also a place of production - starting with the TC50, every supercomputer is assembled here.
However, since TC55, there has been no research and development of supercomputers for two years: in 56 and 57, only T56MT57M medium-sized computers and T56L/T57L mainframes were launched. enough.
The abnormal user is the National Meteorological Administration. To meet the needs of abnormal users, a supercomputer with a new architecture is necessary.
"Li Qiang!"
In the supercomputing hall, several people were doing the final inspection and assembly. When Tang Hua entered, he saw Li Qiang at first sight.
Li Qiang: "Minister Tang, if you come in another three to five days, you will be just in time for the supercomputer to start up for the first time."
Tang Hua: "Then there is not much novelty, let's take a look at the supercomputer at the end of the assembly, the exposed circuit boards, the bundles of cables, and the heat pipes and fins that can be seen at a glance. It's a sense of technology."
Li Qiang laughed loudly, "Didn't you say that the more concise the more advanced, at the third supercomputing meeting?"
"In a certain period, the high-performance computer system will be complicated. After we use the complex design to achieve the required performance, we will go back to simplicity. Now is the stage of the complex system... What about the old column?"
Li Qiang: "Lebedev's granddaughter is born, and she is at home looking after the baby."
Lao Lie came here with his whole family, and his daughter arranged a job in Shanghai as a Russian translator. The year before last, he married a young man surnamed Cheng from the Computer Institute.
……
"Cabinet 3-7 is complete." "Complete? Then pressurize the cooling pipeline."
The supercomputer uses water cooling to cool down.
This is the third time that the supercomputing conference has been confirmed.In the previous experiment, using a heat sink to dissipate heat from the chip, it seemed that the laboratory test passed the test, but when trying to stack up dozens of circuit boards covered with chips and test again, the heat sink failed again.
Add a small electric fan to each heat sink, that is, thousands of cooling fans, which cannot guarantee that all of them will work normally.If one does not turn, the underlying chip may overheat and die, or even burn the chip.
Everyone pondered for a long time at the meeting, and finally decided that liquid cooling is the only way.
Tang Hua and Li Qiang came to cabinets 3-7, which is the No. 7 cabinet of the third core.The cooling system is filled with water, started, and the noise is very small - the motor is a few meters away, sending cooling water into the dense and complex cooling pipeline.
"It's all copper, and the cost of raw materials and brazing is not a small sum," Li Qiang said. "There are also water pipe connections, because the process requirements are particularly high, and there must be no leakage at the pipe connection, so we are looking for top technicians." , After the pipeline is completed, it needs to be checked repeatedly.”
