Although this division method is simple and crude, what is interesting is that oil and gas resources happen to be most concentrated in the three subsidence zones.Many offshore oil and gas fields have been explored in the first subsidence zone, and Daqing Oilfield, Shengli Oilfield, and Zhongyuan Oilfield in the second subsidence zone.The two basins in the third subsidence zone have natural gas reserves in Wuyang and Wuyang.

In the X group laboratory of the Institute of Computer Science, Tang Hua saw TC54.Tang Hua had already seen the cabinets before going to the Soviet Union. In the past two months, Lao Lie led the supercomputing team to debug the system in Beijing and it is ready for use.

But TC54 was not sent to Jiaohe 50 center - TC53 was used there well.

In addition to seeing the first operational TC54, Tang Hua also saw the second TC54 being assembled.

From TC50 to TC53, only one supercomputer is produced for each generation. The TC54 is also a limited edition, but for the first time ever, more than one unit will be produced.

"The supercomputing speed of integrated circuits can no longer be described by previous numbers." Lebedev said, "I know that TC53 is already in a state of excess computing power, and the volume of TC54 is only a quarter of that of TC53, but its computing power has reached 53 times that of TC2.2, if it is still used for the original purpose, I am afraid that there is a serious excess of computing power."

Tang Hua: "It has new uses. In the fields it will be used in the future, computing power will never be too much."

"So where will the TC54 be installed?"

"One in Beijing and one in Shanghai. The Bureau of Electronics and Information Industry will build two computing centers to run supercomputing and provide data computing services to several specific departments. The second TC54 will be installed in Shanghai," Tang Hua said. Said, "But Lao Lie, you'd better go back to Shanghai now, because Beijing is about to enter the dust season."

Lebedev looked at the yellow sky in Beijing outside the window and nodded.

……

"Tang Hua, last Thursday Cheng Wang from the Shipbuilding Industry Bureau sent a telegram from Shanghai asking for help."

Tang Hua took the telegram from Deng Fa and enjoyed watching it.

The Soviet ship tycoon and the Japanese master fought.

But this is not a serious incident, and the two are arguing about it.

Tang Hua first sent a telegram to Cheng Wang and Zubov, saying that the Type 56 destroyer built according to the import agreement would not make any changes in line shape and hull.There was no way to change it... These two destroyers not only used Soviet blueprints, but also shipped parts and materials from the Soviet Union. Shanghai was actually only assembled and built.

Mr. Makino is talking about which direction China should develop in the future if it designs and builds its own destroyers, rather than saying that the first two Type 56 destroyers assembled and built by China will undergo surgery.

Then, Tang Hua sent a message to the Shanghai Computer Institute, asking the Shanghai Institute to invite Mr. Makino Shigeru to come to the communication computer terminal to chat together.

With the help of the communication line of the Chinese postal system, an experimental computer communication line has been established between the Beijing Institute of Computer Science and the Shanghai Institute of Computer Science.

Of course, the communication line of the post office is not strictly confidential enough, and the dedicated communication link can only be delivered in November to December 1954. But in this era, apart from China, who else can decode and understand the data of computer communication?

"Is this the scientific research institute of the Electronic Information Industry Bureau of the Ministry of Heavy Industry of the Chinese government?" Shigeru Makino asked Wang Shoujue when he entered the door.

Wang Shoujue: "Yes. Strictly speaking...the secret level here is one level higher than that of the Ship Design Institute. You are visiting with special approval, so please stay within the designated area in the office building and do not visit other rooms and floor."

……

Knowing that this is the birthplace of the magical computer he used, and probably also the place where the core components of various Chinese missiles were born, Shigeru Makino was inexplicably excited.

Going up to the second floor and coming to the communication computer laboratory, Shigeru Makino saw the communication computer and the translator and typist sitting in front of the screen.

The computer screen has been divided into two from the middle, the left side is the text interface of his own machine, and the right side is the text interface entered by Beijing Tanghua.

"Mr. Makino, how have you been in China these past few months? How do you feel about the computer system of the Ship Design Institute?"

What Tang Hua typed on the screen was in Chinese, but Makino Shigeru could recognize most of it. Before the translator could read it, Makino Shigeru replied: "Living in China is not bad. The magical computer is the most powerful tool for ship design. If computer systems are used to assist in the design of the Yamato battleship, the design cycle can be shortened from 3 years to about 1 year."

"In the future we will have faster and more powerful computers, making computers the most useful helpers in engineering design and construction supervision."

"The Type 56 destroyer was an additional project introduced by the Soviet Union last year. Since the manufacturers of domestic ship supporting facilities are far from complete, in the contract we signed, the first two Type 2 destroyers were completely assembled with materials and parts provided by the Soviet Union. Yes, it is not suitable for any modification. The two destroyers will start construction in November 56. In fact, before the start of construction, the two shipyards in Shanghai still have heavy training for shipbuilders and technicians. While testing and building, two 1954 The berth cycle of the Type Destroyer is expected to be 11 years."

Makino Shigeru: "Yes, I fully understand. According to this plan, in November 1956, the two destroyers will leave the berth to enter the outfitting stage, and then the sea trial stage. I am now thinking about what warships should be built on the berth The problem."

Tang Hua: "In November 1956, some of China's ship supporting facilities manufacturers could be completed, but some were still under construction. It is foreseeable that we still need to import TB-11 steam from the Soviet Union in November 1956 The turbine system, the main propulsion shaft, that is, the entire power and propulsion system will be roughly the same as the Type 11 destroyer. I guess you have formed a preliminary concept of an improved Type 8 destroyer and exchanged ideas with Comrade Zubov."

Makino Shigeru: "The Type 56 destroyer is a destroyer with a severe excess power system. If it is placed in the environment of World War II, its high speed capability is also quite excellent, even surpassing all Japanese destroyers except the Shimakaze class. .But like those destroyers, the Type 56’s battery life is not outstanding. Its battery life is only 685 nautical miles at extreme speed, and 3500 nautical miles at an economical speed. The extremely thin hull also weakens its stability. My idea is that all The length remains unchanged at 126 meters, the width increases from 12.7 meters to 14 meters, the maximum displacement increases from 3200 tons to 3600 tons, and the design speed decreases from 36 to 38 knots to about 32 knots. But the endurance can reach 4500 to 5000 nautical miles.”

Tang Hua: "The design index is too plain. If possible, the displacement should be increased to about 4500 tons, mainly by increasing the width and reducing the aspect ratio. The TB-8 steam turbine system is still used, which is the main engine with 72000 horsepower. Under such conditions, what speed can the ship reach?"

Shigeru Makino: "Is this a scientific research mission for Shanghai Ship Design Institute?"

Tang Hua: "The ship model tank has been completed, I hope you can spend a year looking for the best line shape, and constantly optimize the parameters according to the test, so that this 4500-ton ship with an aspect ratio of no more than 8.5:1 can reach the highest possible height. speed."

……

After chatting with Shigeru Makino, Tang Hua found out Li Qiang who was staying in Shanghai for a chat.

Now the director of the Electronic Information Industry Bureau is Li Qiang... After Tang Hua changed from the acting minister of the Ministry of Heavy Industry to the minister, he asked Li Qiang from the Communication Department of the General Staff.

Because about 60% of the factories and enterprises in the electronic information industry are located in the middle and lower reaches of the Yangtze River, Li Qiang went to Shanghai after taking office, and has been wandering around Shanghai for two months.

"Software Center of Shanghai Research Institute, how is the development progress of geometry and load case simulation software?"

After understanding the results of Li Qiang's investigation, Tang Hua asked about the software.

"The version used on small vector machines will have to wait a while, and the version used on general-purpose computers should already have a trial version."

"On the basis of the trial version, customize a supercomputing and optimized version, and try to get it out in the fastest time. There are large-scale simulation calculations in Beijing that may need to be run as soon as possible."

……

The "fastest time" given by the Software Center of Shanghai Institute of Computer Science is two weeks.

It also happened to take these two weeks to reflect the results of the negotiations to the Soviet Union into the nuclear industry construction plan.

According to the terms listed in the Sino-Soviet "Atomic Energy Cooperation Agreement", all the nuclear industry construction plans in 1954 and 1955 can be implemented, and most of the work in 1956 can be implemented. After that, the work should be done by itself or continue to get help from the Soviet Union. It will depend on whether China and the Soviet Union further discuss more in-depth cooperation in atomic energy.

"Minister Li, it's April again in a flash. I don't know what big moves the Ministry of Geology has made recently."

Li Siguang: "We are now the prospecting department."

Both Tang Hua and Li Siguang laughed.

The Ministry of Geology is now the "Department of Mineral Prospecting and Plant Site Survey and Determination".

Therefore, the Ministry of Geology was directly called the "Ministry of Geology and Mineral Resources" for a period of time.

Tang Hua: "I've been working on this computer for a month. Oh, you may not have seen this kind of computer before. The computer with a large cabinet you used before is actually called a general-purpose computer. This one is called a computer. supercomputer."

"Recently, several comrades from the Computer Institute are busy inputting these things into the computer. They are some data from you and the Ministry of Geology."

Li Siguang looked at the cabinets arranged in an X shape.I looked at the stack of data again: "Looking at my country's Petroleum Exploration Prospects from Tectonics", "Basics and Methods of Geomechanics", "Some Typical Structural Types in East Asia and Their Significance to Continental Movement", "Spiral Structures and Tectonic System"...

"Why do you still have Huang Jiqing's book? Throw it away, throw it away quickly"

Tang Hua grabbed Li Siguang's hand with a dark face, and snatched Huang Jiqing's "China's Major Geological Tectonic Units".

Two schools of geology, two enemies... But it was too late for Li Siguang to throw away the book, and the algorithm in Huang Jiqing's book had already been taken out and used in the software.
