About 95, there has been a lot of controversy since the day of birth, and the author does not argue about it. Just one thing to say: the novel is talking about the 95-2 improved type, which is not a model in reality, just a little imagination that the author collects the views of military fans. So it's really hard to say anything about the accusations of the first version of 95.
……
Qiao Kangsheng, a member of the Faculty of the Chinese Academy of Sciences, walked with his hands behind his back and walked with a smile in the Seiko workshop of the Precision Machinery Factory of the Military Division, looking east and west. From time to time, he stopped, squatted in front of a certain piece of equipment, watched carefully for a while, and took advantage of the operator's break to pull the other party to ask.
After the successful commissioning of the vacuum electroslag remelting furnace, most of the experts have left one after another due to problems in the unit. There are also some experts who are not so busy with affairs, and their status and units are not good at forcing them to go back, so they stay here and work with the technicians of the military sub-district to do more in-depth research on the use and improvement of the vacuum electroslag remelting furnace.
Scientists are experienced technicians who are focused on their own business, and they are slow to do anything outside of their own work. But no matter how sluggish I was, after a long time of contact, I still found many things that were different from those in China.
For example, the most important experimental equipment for technical research is the basis for the work of scientific researchers. Without high-precision observation and control instruments, even the world's greatest scientists would not be able to engage in increasingly detailed microscopic research with the naked eye and a pair of hands.
These equipment are all baby bumps in China, and no research institute can pat its chest and say that it is fully equipped. If a research unit has one or two imported instruments, it is the same as taking care of the eyeballs, and the baby is very good: special person to take care of and maintain; How far in advance must you apply for a single use, and then queue up; Before use, you must not train on the machine for a long time, and you can only get the opportunity to use it after you are proficient; The operation time is strictly strangled, and it is not possible to do more than one minute; The consumables in the test are accurate to the gram, and there is no more than a ......
But when it came time to borrow equipment from the special alloy plant, they were surprised.
When they came, they roughly knew that the technical departments of the military sub-district enterprises were different from the large domestic enterprises that had their own research institutes, and that their technical strength was relatively weak. A large amount of research work is to cooperate with the corresponding research institutes, and the research funds and topics are provided by the enterprises, and the research institutes carry out research verification, which does not have much research ability.
But in the special alloy factory, the equipment in the laboratory building was surprisingly good.
Ore phase dissociation analyzer, metal in-situ analyzer, high-temperature X-ray diffractometer, high-resolution Raman spectrometer, ...... all kinds of common and uncommon instruments in metallurgical research institutes, there are a lot of them!
Although the production unit on the label of the instrument is the precision instrument factory of the military division, the internal structure is still the familiar style of the domestic manufacturer. So at first, the experts were secretly laughing at the military division for slapping a swollen face and becoming fat, and changed the label of the equipment bought in China to say that it was their own.
Therefore, at the beginning, everyone just lamented that the military division was rich and willing to invest, but they didn't have much feeling.
After all, what is the quality of domestic instruments, they have the most say in keeping up with the pace of development of precision instruments: it is okay and can be used, but it is still worse than that of the Soviet Union, and it is even worse than a small number of imported instruments bought from Europe and the United States.
The military sub-district has money, and everyone is a little envious, so it's just that.
In response to the experts' request for borrowing equipment, the military sub-district was very generous, actively helping to adjust the time period for use, and allocating half of the equipment time to experts from China.
But in the waiting stage, when they saw the actual use of the equipment by the alloy factory's own technicians, they were angry: their actions were not standardized at all, and many operating procedures were strictly prohibited in China because they could damage the equipment. And with such good equipment, they only do some very rudimentary inspection work, and the waste of materials is so big that onlookers are furious.
These technicians are novices at all!
At home, they are turned away even if they want to enter the laboratory, and they are watched as saboteurs if they get closer.
The special alloy factory has such good equipment, but it is used to train new people, this, this, it is really too wasteful, so wasted that outsiders can't stand it!
But after all, this is a private matter of the people themselves. People are rich and capricious, that is, they want to take expensive equipment and invest a lot of money in consumables to train novices, and no matter how unpleasant the experts look at them and are unbalanced, they can't interfere.
Some well-meaning experts simply spoke out, instructed them how to write the test process scientifically, taught them how to operate the equipment correctly, and became their teachers.
During the teaching process, they were amazed after actually using these devices.
These equipment are obviously domestic internal equipment, but the measurement accuracy and degree of automation are unexpectedly high, and they are not much worse than the imported equipment they have used!
Shocked, they hurriedly asked what was going on.
The technicians of the special alloy plant were completely confused by their gaffes. These technicians are indeed 100% novices, and only a few technical backbones are hired from China. But even these technical backbones are second-rate in China, so they will be sent here to help the military sub-district establish its own small industry and scientific research system.
For the experts' inquiries, these technical backbones are also the second monk who is puzzled, and don't understand why they are making such a fuss, is there no such good equipment in China?
It's impossible, these equipment were originally ordered from the domestic scientific instrument factory, but they were first sent to the precision instrument factory of the military subdivision for a little improvement, is it necessary to be so exaggerated?
was asked by the other party like this, and the domestic experts were also stunned, wondering if they were overreacting. Maybe the domestic instrument factory has already had better equipment, but I don't know it, or the institute didn't buy it.
As a result, the experts flocked to call the country and reported the nameplate and model of the copied equipment to the unit, saying that this model was much better than the original old model. Ask them to ask the domestic manufacturer if they have this type of instrument, and if so, they must buy one.
However, the information fed back from China has not been found to be so!
Whether it is Beijing, Shanghai, or Wuhan, this model of instrument has never been launched. On the contrary, they undertook orders from military divisions to carry out partial modifications of the instruments according to their requirements, but that's all, and they did not know anything about the purpose and purpose of the transformation.
The experts were confused about other things, but they were not slow to react to these major events that were closely related to their research, and immediately understood that these instruments had been purposefully modified by military divisions, and it was likely that some accessories had been added to improve the measurement accuracy of the instruments.
The more I thought about it, the more I felt like a cat scratching.
After all, this is on other people's territory, and the improvement of the instrument must be an absolute secret that cannot be publicized, so how can the military sub-district disclose it to them?
The vast majority of experts can still maintain discipline, although 10,000 want to understand the reason, but still hold back the impulse in their hearts. Only a very small number of young and middle-aged scientific and technological workers, as soon as their brains were hot, ran to make a request to visit the precision instrument factory. The leaders of the inspection group, who learned about it afterwards, brought them in and severely criticized them, saying that they were unorganized and undisciplined, seriously violated the discipline of foreign affairs, and caused problems for others.
After criticizing here, who knows how to turn their backs, but unexpectedly, the military sub-district agreed to their request and welcomed them to visit freely accompanied by various enterprises. It is hoped that they can help the military sub-district discover problems and put forward suggestions for improvement.
It was a bonus.
The experts who received permission immediately went out en masse, accompanied by the office staff of the precision instrument factory, to visit their manufacturing workshop.
When they went, they were shaken again.
In their opinion, the construction of the special alloy factory is already a super high standard, not at all like the domestic metallurgical enterprises, dirty and messy, all kinds of equipment, components, raw materials are piled up indiscriminately, dozens of people are crowded back and forth in it, making the workshop as chaotic as the vegetable market when the stall is closed. The plant of the special alloy factory is as clean as new, and after a large number of automatic control, there is no need for too many personnel in the workshop, and there are more than ten people in a team, each with a fixed post, which is very orderly. With the assistance of automated crane and rail transportation equipment, just a few people can easily do their jobs.
But when they arrived at the precision instrument factory, they knew what was small.
The workshop of the precision instrument factory is not so majestic, it is a simple steel structure workshop. However, the internal management is strict, even for the most high-end laboratories in China.
The manufacture and supply of all kinds of ultra-pure water, strict to harsh dust removal management, clean air to keep the particulate dust to a minimum, and even the direction and intensity of light have certain rules.
In order to ensure the highest level of cleanliness, the workers sitting on the production line even wore coveralls with their heads and faces covered, and only watched and worked through the face glass!
On the transmission belt, circuit boards pass in front of thousands of workers, all of whom are nervously engaged in their work, and have no time to look around. To complete a job of your own, you put the circuit board into the inner conveyor belt, send it to the next link, and then pick up the next piece from the outside conveyor belt to work on it. Each person has a workbench with automatic spot welding equipment, microscopes, and comprehensive testing equipment, which is comparable to a small laboratory.
What kind of production line is this, it's just a super-large-scale laboratory!
Compared with domestic precision manufacturing enterprises, the doors and windows are sealed, an exhaust fan is added, and the workers wear a white coat and a hat are considered to be clean workshops, and the conditions of the precision instrument factory are simply outrageous!
Only such a high-cleanliness workshop can manufacture such high-precision scientific instruments, and everyone is convinced after seeing the production line.
When the domestic experts left the workshop in a trance and stumbled upon more than a dozen transport convoys with obvious characteristics of domestic instruments, they were excited. This proves that the military sub-district has indeed purchased a large number of scientific instruments from the country, and this is not wrong.
They enthusiastically followed the convoy and came to the warehouse, where they found thousands of instruments stacked here, and all the product nameplates were clearly marked with the names of domestic manufacturers.
As soon as these instruments are put into storage, some of them are transferred to the production line.
followed to the production line, and they saw the scene that made them angry and sad: the same ultra-clean workshop, the same headsuit, but the task of this workshop is to disassemble! They dismantled the instruments they had purchased from China, kept the mechanical parts, and threw the electrical parts into the recycling bins on the side like garbage.
That's the truth!
Originally, the military sub-district purchased a large number of scientific and educational instruments from China because of its own processing capacity, which temporarily prevented it from processing a large number of precision mechanical components and could not produce optical components such as scientific lenses. But they also only need parts that these military divisions cannot temporarily withdraw, or whose production capacity is insufficient to meet their needs, as for the control circuits, from circuit boards to components, all of them are produced by the military divisions!
To put it mildly, just like special alloy factories and precision machinery factories, between the domestic and military divisions, domestic enterprises play the role of suppliers of primary processing materials and semi-finished products. The military division is the end of the entire production chain, responsible for the highest technical content of the link, the primary processing of materials and semi-finished products purchased from the country, in-depth processing, finishing into the final products, and then sold back to the country or exported!
And in order to improve the degree of automation of the instrument and the ability to analyze the numbers in detail, the number of processors used in the circuit is simply appalling!
Wherever the processor can be used, the corresponding modifications are used. Depending on the complexity of data processing, from the earliest 4040 to the latest Z80, 8086, 8088, everything is available! The latest 8086 and 8088 have not even been thoroughly eaten in China, and they have begun to be used on a large scale!
After understanding the whole process, they no longer had any doubts about why the self-produced instruments of the military sub-divisions, which use domestic instruments as the internal equipment, have such high precision, convenient control, and fine adjustment functions.
Even if the domestic optical components are a little worse, but under the transformation of the military division at such a cost, it cannot greatly improve the performance of the instrument, that is hell!
