Tang Hua hung up the phone and continued to play with the mouse in his hand.
It took the Yizheng Computer Peripherals Factory more than a year to realize the rough mouse solution proposed by Tang Hua.The first mouse was a big square box with a wire dragging it. Tang Hua felt dissatisfied. He modified the shape in the past few days, at least making it a little rounder and more comfortable to hold in his hand.
"When the mouse is currently in use, a program needs to reside in the computer's memory, which takes up more than 1K of space," Tang Hua said. "So, it is a bit difficult to use the mouse on a general 4K or 8K computer."
Li Fuli: "Anyway, this advanced CAD machine with 32K memory must be fine."
The medium-sized computer dedicated to CAD now uses a "huge" 32K memory.
Well, a computer with 32K memory is loaded with a mouse, and it is indeed no problem.
"There is one matter. Director Cheng and I have exchanged views several times, and I have asked for your opinions once before. Taking advantage of this opportunity, let's hold a small meeting to discuss and make a final decision," Tang Hua said. In the process of expansion, there are civil ship designs, military ship designs, surface ships, small boats, and submarines. Especially in the design of submarines, the submarine itself is very complicated, and it also involves conventional and nuclear power. The number of design teams in the future will be relatively large. many."
"At present, the submarine construction plant is in Wuhan, and the second submarine production base in the future is Dalian. Therefore, we are faced with a problem, should we transfer the submarine design team of the Shipbuilding Research Institute to Wuhan and establish the Wuhan Shipbuilding Research Institute?"
The main members of the Ship Design Institute spoke one after another.
"If the design unit is located in Wuhan, we can indeed go to the shipyard frequently and contact the submarine under construction from time to time, which is beneficial to the implementation of the design drawings." Huang Xuhua said.
Pan Jingfu: "Everyone in the Ship Research Institute works in the same building. It is very convenient to communicate with each other when we have some ideas. This is called brainstorming, right? Whether it is a submarine or a warship, some design concepts are still interlinked."
Li Fuli: "Moreover, in fact, nuclear power is not a unique element of submarines, and the possibility of nuclear power is not ruled out for surface ships. If the research and design unit of submarines continues to stay in Shanghai, it means that after the design of nuclear submarines , and everyone gained some research design skills for nuclear-powered ships."
Tang Hua remembers that Peng Shilu decided to engage in the submarine nuclear power project last year, but he was not seen in today's meeting. "Where's Peng Shilu?"
Cheng Wang: "Xiao Peng is in Baotou, where he is doing an internship and inspection at a reactor designed by our country."
Tang Hua: "Old Cheng, what's your opinion?"
Cheng Wang: "I communicated with you before, and then I thought about it. If the Shipbuilding Research Institute continues to maintain the same establishment of the Shanghai General Institute, the advantages will still outweigh the disadvantages. The disadvantages... that is, the travel expenses of the research and design personnel will be more than that every year." A few thousand dollars."
……
In this seminar in April 59, Shanghai Shipbuilding Research Institute was upgraded to the General Research Institute, but a research station was set up in Wuhan and Dalian, which mostly overlapped with the shipyard’s engineering research office, and the parts that did not overlap were in the When the project is executed, the design team will be dispatched from Shanghai to Dalian or Wuhan on rotation.
In fact, according to the Electronic Information Industry Bureau, the two comprehensive research institutes in Beijing and Shanghai are also the same path, and this path will be broadened in the future. The two research institutes can conduct competition and comparison of large-scale project plans.
But right now...ship research and design are understaffed to split in two.

Call Tang Hua's office at the Shanghai Computer Institute.
It was Qian Xuesen who connected.
"Minister Tang, it's time for the Soviet Union's returnable satellite to release its reentry capsule and re-enter the atmosphere today. We have regrouped in the conference hall."
"Huh? I almost forgot about it.
.It is indeed returning today. "Tang Hua said.
The sixth Luna carrier rocket was changed to a low-Earth orbit satellite carrier, and it was successfully launched three days ago, that is, on April 4.There is no reconnaissance equipment on the returnable satellite, only experimental equipment, and two mice are raised in the return capsule.Therefore, there is no need to go around in orbit for too long, go around for three days, and send a control command when you find a chance, let the return capsule pop out, and ignite the reverse rocket to return to the atmosphere.
If the return capsule lands successfully, it will be the first time humans have successfully soft-landed a spacecraft back to the ground, and the first time humans have sent warm-blooded animals into space and back.
Qian Xuesen: "There is just bad news. The two mice died six hours ago."
Tang Hua: ...
Chapter 216, Big Interlude
The satellite used for return technology verification is called Tianqiong-1. The Soviet Union not only wants to verify the technology of returning an object from space to Earth on Tianqiong-1, but also wants to test whether Tianqiong-1 can transport animals from space to Earth in one step. Safely descend to the ground in low-Earth orbit.
Unfortunately, it failed.
This is a step too far.Previously, Tang Hua suggested that the return capsule of this satellite should not contain mice, but put a few bags of tomatoes, cabbage, and lettuce seeds on it, let the cosmic rays take a photo, and then return to Earth, maybe there will be surprises.But the Soviet Union was already planning its own manned spaceflight program, so it didn't like growing vegetables, and was only interested in sending creatures into space.
So far in Tianqiong-1, the space temperature in the satellite and the return capsule is normal. The mouse must not have died of heat. As for why it died, we have to wait for the return capsule of Tianqiong-1 to land on the ground to find out.
According to Tang Hua's standards, the temperature of the reentry capsule is completely within the allowable range, not to mention forty or fifty degrees, it doesn't matter if it is eighty or ninety degrees for a short period of time, as long as the film is not baked to failure.
On April 4, the return capsule of Tianqiong-14 ejected, and the reverse thrust rocket was activated to push the return capsule back.After circumnavigating the Earth for one third of the way, the return capsule reaches an altitude of less than 1 kilometers and enters the atmosphere.The return capsule, which was close to the first cosmic speed, rubbed violently with the atmosphere, and the temperature of the outer surface exceeded 100 degrees, but under the protection of the evaporative heat dissipation coating and heat insulation materials, there was no problem inside.
On the evening of April 4, in a long strip of the Soviet Union from Yekaterinburg, Tyumen to Baikonur, residents saw small red objects moving rapidly in the sky.When the altitude of the return capsule was lower than 14 meters, the speed had dropped to Mach 1. At this time, the return capsule ejected a parachute and landed slowly in the Gobi grassland near Koskol, with a deviation of 3 kilometers from the scheduled landing point.
After the return capsule landed successfully, it sent a radio signal to the outside. The nearby Soviet army quickly drove off-road vehicles and helicopters to the position of the return capsule. An hour later, the helicopter found the return capsule and quickly airlifted it back to the laboratory in Baikonur. Hatch researched what happened in the past three days.
"Comrade Glebushka, when the satellite was still in space, did you listen to the sound of the mice in the cabin?" the laboratory analyst responsible for detecting the biological environment in the return cabin asked members of the satellite monitoring team.
“We taped the cabin and we heard the rats,” Glebuschka said. “For the first 36 hours in space, the two rats were still squeaking.”
Analyst: "Now I know what those two guinea pigs were talking about."
Glebushka: "Are they talking?"
Analyst: "They're saying: The air is poisonous! The air is poisonous!"
……
This is the result of the test.The water supply and feeder of the mice were normal, the sodium peroxide oxygen generating board was normal, and the heat dissipation of the satellite was normal. However, a small amount of propellant leaked from the reverse rocket installed in the return capsule, which polluted the air in the cabin and poisoned the mice to death.
It seems that this is a small accident. The biological test failed, but the satellite's return technology succeeded.After three days of circling in outer space, the satellite was able to accurately eject the return module, and the return module could ignite itself and open the parachute to achieve a soft landing, and the deviation of the final landing point was only 77 kilometers. This set of actions was executed very well.
Because this rocket test was basically successful, the next step plan was finally determined: in early May 1959, the "Tianyan-5" photographic reconnaissance satellite was launched.
Although the Tianqiong-1 satellite has only achieved 80% success, it has created a record: it is the first successful returnable satellite, marking the first time human beings have recovered space vehicles.In the original history, the first satellite successfully recovered by the return module was Discovery-13, which was completed by the United States in October 1960.
Tianqiong-1 has increased the pressure on NASA in the United States.Not because the Soviet Union won a small bid in the space race, but because NASA understands what returnable satellite technology means: they were planning reconnaissance satellites in 1957, and the necessary condition for photographic reconnaissance satellites is to master returnable satellite technology.
The Soviet Union began to study technology in this area and succeeded.Is the Soviet Union's reconnaissance satellites also ahead of the United States?

Beijing.
Chairman and Vice Chairman Liu greeted the Prime Minister at the airport upon his return from Jakarta.
The Prime Minister and Nehru held a high-level meeting in Jakarta on the southern Tibet issue. The two sides had a candid conversation and exchanged views.At the press conference held after the talks, the Prime Minister commented on the high-level meeting between China and India that "the talks are generally beneficial and have enhanced mutual understanding. I am looking forward to the second and third meetings with Prime Minister Nehru." meeting."
The translation is "the two sides have their own opinions, and the differences are very big. There is no way to unify their opinions. Not only did the agreement fail to be signed, but there was also a lot of quarrel at the scene."
However, although the quarrel was fierce, the two sides did not tear each other up on the spot, and agreed to sit down and talk again at an appropriate time. This was probably the only consensus between China and India during the meeting in Jakarta.
When Nehru returned to India, the debate on southern Tibet in the Indian Parliament was still going on. The nationalist faction demanded that the Chinese be driven back to the Himalayas. The pragmatic group believed that India could not afford the military expenditure to recover the "occupied territories".
In order to appease the emotions of both parties, Nehru had no choice but to announce in Congress that he could ask the Minister of Defense to send another 5000 troops to eastern India and build three military airports in eastern India.
The parliament voted quickly, and the plan to increase the number of troops by [-] was confirmed.A proposal to build three military airfields was cut into two.
... At this time, India's finances were really not well off. When it came to money, everyone became rational.
