"Yeah, I remember it. Could it be that there was another war today?"
"No, no, it's not a war, and it doesn't have much to do with us."
……
Beijing-Tianjin-Nanjing-Shanghai.In Nanjing, the train still has to take the ferry to cross the Yangtze River.
This time I went to Shanghai, the first thing I did was to see Lebedev.The Ministry of Education of Ukraine and the Soviet Union has issued a 10-year dispatch expert certificate to Lao Lie, so he can live in China steadily.
Then there is the Shanghai Institute of Computer Science. The T54 computer to be launched next year is still a transistor computer. There is no technical difficulty at all. Tang Hua has already handed over most of the detailed design to Wang Shoujue and the others, and it is said that the performance during the test is not bad.
The site of the Shanghai chip factory was selected at the beginning of the year, and it is probably digging the land now.There are also a large number of factories or factory complexes in the Electronic Information Industry Bureau around Shanghai.
But none of this seems to be new.The new thing is that Shigeru Makino has arrived in Shanghai, and has been hanging out with the little comrades from the Design Institute of the Shipbuilding Industry Bureau for half a month.
When you come to Shanghai, you must first meet this famous ship designer in the old Japanese era.As one of Yamato's construction designers and the chief designer of the Kagero-class destroyer, it was really an accident that he came to China.According to the staff of the embassy, he admired China for defeating the U.S. military on the Korean battlefield, and it also overwhelmed the U.S. not only with flesh and blood but also with some technologies.
... He really is a guy who has not recovered from the second disease.I hope he just worships technology, not fascism.Worshiping fascism can be troublesome.
In addition to these things, it has been confirmed that the Navy Development and Ship Industry System Adjustment Work Conference will be held on July 7 by the Ministry of Heavy Industry, the Shipbuilding Industry Bureau, and the Navy.

As the train drove into Jiangsu, Tang Hua saw that the water volume of the Huaihe River was much healthier than in previous years. Then he remembered that a huge project had been completed in the past two years: the Northern Jiangsu Irrigation Canal.
Starting from Huai'an City on the bank of Hongze Lake in the west, it flows through Huai'an, Qingjiangpu District, Huai'an District, Funing County, Sheyang County and Binhai County, with a total length of 168 kilometers. 60 cubic meters per second.
When the People's Republic of China was first founded, the Huaihe River had no mouth.Every year, the amount of water is silted up in the middle and lower reaches, and floods and soil salinization have always been serious problems in northern Jiangsu.
In 1950, the Premier proposed to eradicate the Huaihe River.Chairman's inscription "We must repair the Huaihe River". In 1951, the Northern Subei Irrigation Canal was officially started and completed in May 1953.
He just dug a dredging channel for the Huaihe River, and it was dug out mainly by manpower when there were not many construction machinery and even insufficient explosives.
But Tang Hua recalled that the current Northern Subei Irrigation Canal can only be regarded as the first phase. It is not that the phases were planned early in the morning, but that the scale of the Huaihe River flood was underestimated in the early days of the founding of the People's Republic of China and the maximum water flow was designed. Not enough flux.
After the catastrophic flood of the Huaihe River in 1954, it was found that the standard of the construction project was low, and it began to ponder about building a channel into the sea on the basis of the main irrigation canal in northern Jiangsu.At that time, the hydrological survey found that the flood peak entering Hongze Lake was as high as 10755 cubic meters per second, but only 8000 to 8500 cubic meters per second entered the river, and the remaining 2250 cubic meters per second could not be discharged.
So the only option is: dig the main irrigation canal in northern Jiangsu all the way to the sea, and dig out the mouth of a river.
It was expanded to withstand the flood peak in 1954, and then encountered the 1975 catastrophic flood in August 8, and continued to expand...
It has been repaired and repaired until the 21st century. The design flow rate is 7000 cubic meters per second. The three rivers flow in parallel and go straight to the Yellow Sea. In order to separate it from the Grand Canal, the Huai'an Water Overpass was built, but several unique scenic spots were born.
After thinking about it, back to June 1953, what Tang Hua had to solve was: When will the Ministry of Water Resources have a basically functional national hydrological data center?
Chapter 5, Li Siguang, the king of car wrecking
Shanghai. June 6.
An object that looked like a car was unloaded from the flatbed wagon at the railway station, and drove unsteadily towards Sinan Mansion.
If you look carefully, you can still see that this is a jeep.If you look at the remaining paint color near the rear of the car, you will know that its original paint color should be lake blue.
Only one of the two panes of glass on the front of the Jeep remains.The side windows were simply gone.The center to rear canvas roof must have been ripped and stitched back on, and there is a long patch line of stitches running from the top center to the left rear.
All the steel plates on the top and bottom of the car seem to be a little deformed, the hood cannot be closed, and it warps like a crooked smile.The radiator grille in front of the hood has long since disappeared.
The Jeep's original two headlights were long gone, too, and now there are two truck lights strapped with wire to the left and right of the front of the car, with rubberized wires leading directly from the grinning hood to the replacement lights.
Li Siguang, Minister of Geology and head of the Jiangxi Special Mine Exploration Team, sat in the left co-driver's seat, holding the car door with one hand to prevent the unlocked door from suddenly opening. Of course, the left and right rearview mirrors were rubbed off.
"Going back, you should turn right on this road, and then drive straight for seven or eighty meters, yes, this is it," Li Siguang directed the driver, "The horn is also broken, isn't it? Let's yell."
"Minister Tang~~~" "Tang Hua!"
……
As soon as Tang Hua arrived in Shanghai, he received a telegram saying that Li Siguang's exploration team had finished their investigation and was leaving for Shanghai on the 30th, so they were waiting at home all day on the 30th.Hearing someone shouting outside the building, he went out to the yard to have a look.
Good guy... so straight up, good guy...
"This is a Land Rover, or Boss Rong's car..." Tang Hua sighed, and the Land Rover Series 1 in front of him was completely a pile of moving scrap iron.
Looking at Li Si's messy appearance with bald hair and beard, and his work clothes with a few scratches, it seems that he is not much better than a jeep.
In August 1952, the Volunteer Army's Tu-8 radiation detection plane made a circle over Fuzhou, Jiangxi, the later "uranium capital of China", and detected a relatively high gamma anomaly in the Xiangshan area of Fuzhou.The preliminary exploration team of the Ministry of Geology from September to October found that there was indeed indirect evidence of the existence of uranium deposits, which seduced Li Siguang.He mobilized elite soldiers and a full set of exploration equipment including imported tungsten alloy drill bits, and organized an exploration team to go to Fuzhou, Jiangxi Province for detailed investigation.When saying goodbye, Tang Hua borrowed the Land Rover from Rong Yiren for Li Siguang to use.
"Tang Hua, this car has already been done like this... I might as well buy it."
Tang Hua: "It's just a car. The two Land Rovers I ordered have already been shipped from Hong Kong, and I returned one to Boss Rong. There is another one here. It's not a big deal."
"This car has been with me for several months, and I have already developed feelings. I have to keep it no matter how broken it is."
……
"The last time we met, it seemed to be New Year's Day in 53, right? It's been half a year in a blink of an eye." Sitting down in the living room, Tang Hua took out two wine glasses and poured red wine.
Li Siguang took the wine glass, raised his neck and gulped it down. "Phew~~ I'm much more comfortable now. It was January 53, 1, the day after New Year's Day. It's half a year short of four days."
"You have been wandering in the mountains of Fuzhou for half a year."
"Our exploration team first surveyed Xiangshan, Fuzhou, and then several nearby counties. The results were great. After that, I asked the exploration team to split up and continue to explore the surrounding areas of Fuzhou. I went west and explored all the way to Xinyu. " Li Siguang opened the conversation, "After the exploration of uranium mines, I thought that my research on Quaternary glaciers and the structure of China's land would need to obtain some first-hand information in Jiangxi. So I went to Jiangxi to investigate again. It took more than 40 days. I have done research on the Yangtze-type Nanhua Period-Middle Triassic marine caprocks before, and this investigation in Jiangxi has added a lot of marginal geological evidence."
Tang Hua has heard of the latter geological term but has never understood it.However, Tang Hua understood one of Li Siguang's words: "Wait a minute, the results are great? Does that mean that the uranium mine has a spectrum?"
"Xiangshan really has a super big mine. I don't brag at all. This is a discovery that shakes the world." Li Siguang opened his handbag and took out the documents and reports. , the burial of this Xiangshan uranium mine is extremely shallow! The grade is medium, about [-]% to [-]%, but the ore volume is extremely huge. I made a rough calculation, which is equivalent to natural uranium in Thirteen thousand to fourteen thousand tons."
By the 21st century, the Xiangshan uranium mine has discovered a total of nearly 5 tons of natural uranium reserves, of which 500 tons are in veins with a depth of less than 1.6 meters, and the rest are in rock formations between 500 and 2900 meters.The prospecting results of Li Siguang and his exploration team exceeded Tang Hua's expectations - he originally estimated that they could find no less than [-] tons of reserves, but now it is [-].
"Thirteen thousand tons of natural uranium, which is equivalent to more than 90 tons of uranium-235, can make more than 1000 atomic bombs, Lao Li, we really made a fortune this time!"
Although he already had the answer, Tang Hua happily grabbed his glass after hearing Li Siguang say it himself, "I must have a drink."
"The total reserves of Xiangshan uranium deposits may be more than 3000 tons," Li Siguang said after toasting, "There are still some areas in Xiangshan that show signs of uranium deposits, but the current exploration tools are not particularly perfect. We can find out where the specific mineral veins are.”
"These mines should be located in relatively deep places. Not only is it difficult to explore, but the cost of excavation is estimated to be relatively high. Then we are not in a hurry, and we will explore and mine slowly in the future." Tang Hua said, "Now this The reserves of more than 3000 tons are enough for us to start the nuclear industry.”
……
"Vice Premier Chen."
Although the discovery of a large uranium mine has not yet been approved and classified by the organization, both Tang Hua and Li Siguang treat it as confidential information.At this moment in Shanghai, the only person who can know the news and discuss things together is the chief accountant.
Tang Hua and Li Siguang went to the chief accountant the next day.
"Oh, oh," the chief accountant directly opened the general statistics of uranium resources, "300 million tons of ore, with a net content of more than 1 tons, can make more than 1000 atomic bombs, which is amazing. However, if we want to do this , we have to import modern uranium mining facilities and smelting equipment from the Soviet Union."
Tang Hua: "I think that the Soviet Union will aid in the construction of uranium mining equipment and smelting equipment. We only need to provide manpower, and the foreign exchange spent on the equipment will be repaid with the mined uranium. It is just that the State Planning Commission and the Government Administration Council need to ask the Soviet Union again. It is proposed to engage in a negotiation on mutual assistance in special mineral deposits."
