Wu Xiuquan: "The United States and the Soviet Union both send ambassadors to each other. As a South American country, he is more determined against the Communist Party than the United States. But the current Brazilian government wants to reverse the previous decision. They are now in contact with the Soviet Union to discuss the resumption of diplomacy. relation."
Tang Hua called the Brazilian delegation the "Soybean Group".Their purpose is too obvious: Brazil saw the sudden emergence of grain trade in the trade list between the United States and China this year, and wanted to see if there was any hope of selling soybeans.
……
"Hello, Vice Chairman Liu." "Hello, Commissioner Honecker."
After Vice Chairman Liu, Tang Hua and Erich Honecker shook hands and said hello.
Honecker... is not yet the chancellor of East Germany, but he is already a member of the bureau, in charge of security affairs and the defense industry.East Germany did not have a systematic defense industry, and he was mainly responsible for security affairs.
But this East German delegation's visit to China does have a considerable part of its agenda related to the defense industry.
"Hello, Headmaster Bell Dürer."
Although it was the first time I met Bell Dürer, Tang Hua had known him for a long time. He was a senior engineer of Zeiss-Jena and the optical system designer of Tianyan-[-] satellite.
Zeiss-Jena is also the contractor for the visible light and infrared dual optical system of the "Fengyun-[-]" weather satellite.
Why subcontract the optical system of Fengyun-[-] to Germany... First of all, of course Zeiss Jena definitely has this capability, and secondly, although Changguang also has this capability, Changguang is too busy.
The current parallel key projects of Changchun Optical Instrument Factory include: the optical system of the Gaofen-[-] optical photographic reconnaissance satellite (nearly completed); the optical system of the Gaofen-[-] reconnaissance satellite (in progress); Early warning) the optical system of the satellite; the optical system of the second generation non-contact mask lithography machine.
Fengyun-[-] is basically a civilian meteorological satellite. The other three satellites all have military backgrounds, and some are highly classified projects. Therefore, Fengyun-[-] can be handed over to East Germany for development, but the other three satellites cannot.
"Mr. Tang, hello!" Dürer was also very excited to see Tang Hua.
"The assembly and test of the optical system of Fengyun-100 passed the first test," Tang Hua said. "To evaluate this project in one word, it is perfect. The lens group [-]% meets the requirements of imaging quality, and there is even a big surprise. Zeiss is worthy of A gem of German precision manufacturing."
"Thank you for the compliment. China's optical instrument industry has also made rapid progress in the past few years, and the Chinese counterparts are not far behind us."
Vice Chairman Liu: "The GDR has been deeply involved in the aerospace and satellite projects of the socialist camp, which proves that you are at the forefront of world science and technology, and are advancing rapidly and firmly on the road of peaceful development."
Tang Hua: "In fact, our optical industry has made such great progress only under the hands-on training of experts from the Soviet Union and Zeiss. Secretary-General Honecker, we have arranged a visit to Tianjin just in time for the first A Fengyun-[-]A satellite. Moreover, you can see the Fengyun-[-]C being assembled, which is the 'German Star'."
After World War II, Germany was divided.Compared with West Germany, East Germany has a smaller territory, a smaller population, and a weaker industrial base than West Germany.Therefore, in various competitions on the international stage, East Germany lost more than it won.At this time, it is very important for East Germany to have a boost, even if it is an obvious image project.
Later, the "International Astronaut Program" of the Soviet Union sent East German astronauts into space. On the day they successfully entered orbit, East Germany was on a national holiday, and everyone was empty. In 1961, if East Germany had a 3-ton meteorological satellite operating in the sky with its own property rights, the "lifting effect" would have been no less than that of the astronaut program.
So when China proposed this proposal to East Germany, Chairman Ulbricht agreed without hesitation.Moreover, East Germany did not spend money to buy satellites. 30% of the cost of a Fengyun-[-] satellite was the optical system, and Germany supplied the optical systems for four satellites. After all, China had to pay some money to East Germany.
But when the meteorological satellite system is in operation, it does not distinguish between you and me. Four low-orbit satellites can ensure that at least one Fengyun-24 will pass by and take cloud pictures in most parts of the earth within [-] hours, so that effective weather forecasts can be made. .
Therefore, East Germany's "buying of satellites" involved a large part of image engineering.But there are also practical benefits: after the establishment of the weather satellite system, weather information in the German region will be provided free of charge; if the weather satellite system sells weather information to Western countries, East Germany will have a share.
Vice Chairman Liu: "At the beginning of January, our first satellite, Fengyun-1A, will be launched. This launch is of great significance, and it is a model of scientific and technological cooperation between China and the GDR."
Honecker: "It's a pity, I should have returned to China at that time, but Comrade Dürer and the technical expert team will always be in China, and they can see the rocket launch on the spot."
……
At the Tianjin Satellite Manufacturing Factory, Honecker saw the three satellites of Fengyun-[-] A, B, and C. Among them, Fengyun-[-]A is already preparing to pack and will leave the factory for Taiyuan in two days.
At the Tianjin Rocket Factory next door, the first Long March-3 rocket that Honecker saw was also ready to pack, but the Chinese and German national flags painted on the rocket body by the rocket factory made Honecker very satisfied.
昂纳克去天津火箭厂的时候只看到了长征-3，东风-5早5天前已经打包运往乌梁素海了。这枚东风-5要打一次高弹道飞行测试，从乌梁素海打往新疆。这既是东风-5的阶段性试射，也是为长征-3火箭测试第一级和第二级发动机。
However, what shocked Honecker and his team the most was the verification prototype of the Fengyun-[-] weather satellite they saw in the test workshop of the Tianjin Satellite Factory.
The prototype has neither a camera system nor a data transmission system. To put it bluntly, it is a "Jianjin-[-]" general satellite platform with solar cells and an electromechanical control system.But it can rotate slightly in a "squeaky" manner in the suspended state, and at the same time, the solar cells and optical lens holes on the satellite also make small adjustments, like an intelligent mechanical life.
"Fengyun-[-] and Fengyun-[-] form a large system, which is the ultimate state of the meteorological satellite system. Meteorological satellites operating in geostationary orbits can continuously observe the same area without intervals. It cooperates with low-orbit satellites to form a A complete meteorological information collection system."
The optical system of Fengyun-35800 was also handed over to Zeiss.Fengyun [-] looks at the ground from an altitude of [-] kilometers, while Fengyun [-] is only a few hundred kilometers away, so the lens groups of Fengyun [-] are all telephoto barrels, which is more difficult to make than Fengyun [-].
However, the launch of Fengyun-4 is not so fast. A rocket capable of sending a payload of more than [-] tons to a synchronous orbit has not yet been developed.

Wuliang Suhai.
Another ballistic missile test mission.
Different from previous test launches, although ballistic missiles were fired this time, the launch towers 1, 2, 3, and 4 of the missile test base were all useless.
In an open space next to the launch center, a Soviet-made heavy-duty trailer pulled a white, about 12-meter-long missile along the road. A cross was painted on a designated location beside the road, and the trailer drove off the road. , Another heavy truck followed by the trailer also drove off the road and worked together on the hard ground, and soon the missile was erected.
"In the end, the medium-range missiles developed like this," said Lao Sun, the commander of the Wuliangsuhai base. Keep running on the road."
Fu Xianhui: "Running around like this, the US missiles don't know where to explode. This is called improving the survivability in a nuclear war environment."
Commander Sun: "The Special Military Engineering Bureau of the Ministry of National Defense has also dug a lot of holes. This is also to improve the survivability."
"It's for these big trucks to hide." Fu Xianhui thought for a while and said, "Our Special Engineering Bureau will become part of the newly established missile force."
"You guys who drilled holes also joined the missile force?" Commander Sun was surprised, "Then we will be in the same military branch in the future. We are the experimental base of the missile force, and you are the hole-drilling army of the missile force."
Fu Xianhui: ...
The launch preparation of Dongfeng-4 was very fast. Less than 20 minutes after it was erected, the command center entered a countdown state-if it wasn't for the first test launch that required calibration and testing of many parameters, it would be even faster.
"4, 3, 2, 1, launch!"
The solid propellant engine spouts flames. Unlike the orange-red liquid propellant tail flame with a little black smoke, the Dongfeng-4 tail flame is almost a white glowing flame, only slightly yellowed at the edge.The missile quickly rose into the sky, and behind the white and yellowish tail flame was a thick white tail smoke trail.
Fu Xianhui: "So the launch was successful?"
"Successful. Let's wait for the observation data from Jiuquan," Commander Sun said, "let's see how the trailers and heavy trucks are collected. I heard that when the Dongfeng-4 is officially equipped with troops, the trailers and heavy trucks must be combined. for one."
"I know, I dug caves for these troops. There is a problem now, whether it is a trailer or a transfer launch vehicle in the future, it has to be imported from the Soviet Union for the time being."
"Our missiles can be manufactured, but the launch vehicle can't be built by itself?"
"...It's really like this. I heard that the original plan formulated by the state for Luoyang was to be completed within 5 years, but later the Planning Commission added a notice. If the technical difficulties are too great, it can be completed in 8 years..."
Chapter 34, Yuan Longping fell into deep thought...
Beijing Agricultural University.
The scientific research achievement report (celebration) meeting of the "Indica Hybrid Rice Collaborative Project Team" of the Department of Agronomy, Chinese Academy of Engineering and the promotion and planting meeting of hybrid rice.
Tang Hua can be regarded as meeting Yuan Longping of this era...
In addition to Yuan Longping, Pei Xinshu, Zhang Xiancheng, Lin Lingyu, a large team of researchers and investigators came to Beijing one after another, and Ding Ying, who has been staying in Beijing recently, gave lectures and conducted scientific research at Agricultural University.
"In the 20s, American agronomist Jones first proposed the theory of rice hybridization. Then Japan immediately conducted rice hybridization experiments in China based on this theory, and there was no sign of increasing yield. I tested Zhongshan No. 1933 in the Nanlu Rice Breeding Field in 55. , and there is no yield-increasing effect. The hybrid rice collaboration that started in 80.00, I, an old man, was just a coordinator and leader, and [-]% of scientific breakthroughs were made by these young people.”
72-year-old Ding Ying is the leader of the project team. He said that the success of hybrid rice is the result of teamwork, and it is inappropriate for him to be at the top of the commendation list.
Deng Zifei: "The breakthrough of hybrid rice is the result of teamwork. At most, there were five or six investigation teams and rice test bases distributed in various provinces. This is a very large team. You are the No. 1 researcher on rice hybridization in China. , and also the chief team leader of the teamwork, you are well-deserved."
Zhang Xiancheng: "Actually, the key node breakthrough of hybrid rice, the wild rice seed, was discovered when Mr. Ding himself was the leader of the investigation team."
