"Before doing the experiment, we are very much like to buy domestic equipment, the price is certainly a good deal, but according to our experience, the domestic instrument used for a period of time is very easy to issue. So, we would rather spend more money to buy imported equipment for longer use." A scientist engaged in the study of the virus so that. Presumably this is the common sense of many of our instrument users. Can be seen that the Chinese domestic instrument products face a crisis of confidence, resulting in the same grade of domestic goods and imported goods can not compete equally, this phenomenon is particularly evident in the high-end scientific instruments.
Present situation analysis of domestic instrument and meter
In technology, the existing domestic low-grade products most and replace imported products, the reliability index of the Montana high-grade product, which is an average failure free operation time compared with foreign products, about differ L 2 orders of magnitude.
In the measurement accuracy, the existing domestic products and foreign products generally differ by 1 orders of magnitude. Because of the lack of research on the basic technology and manufacturing process of the instrument, some key technologies, such as precision machining technology, sealing technology and welding technology, have not been solved well, which leads to the product, especially the performance of high grade product is not stable and reliable.
In function, the degree of foreign production is quite high, and the digital processing of the original information, the influence of external interference on the information is better, and the environmental performance and the measurement of the product are improved. And the degree of domestic existing product intelligence is still relatively low.
Domestic equipment has a characteristic, that is, for the time is OK, but not the long time on the problem. High failure rate. There are many reasons for this: first, the method is not mature, one is the material does not pass, there are quality control is not strict or no capital investment. In addition, since some experts of lofty, is not willing to cooperate with domestic equipment manufacturers, is not willing to come up with housekeeping skills to support the domestic instrument, they prefer to write propaganda of the so-called technical achievements to import instruments.
Domestic instrument development difficult
Demand traction
This traction should be reflected in the scientific research, technology development and production of specific tasks on the need for some kind of instrument. With the need to have people to develop and production equipment, if these instruments are able to capture the market and achieve considerable economic benefits, the natural will have to do.
The traction pull the main problems is our research is still far from becoming the leader in the world today, but is mostly to track research. In this state, the research instruments used in the commercial, the money to buy the mature products. And currently has sufficient funds buyers tend to purchase more ready-made imported instruments seems to in addition to the demand of national defense in the field of high-end equipment, few people are willing to conduct independent research and development or procurement of domestic instruments.
In fact, it is expected to be the world's leading level of experimental scientific research work must rely on their own characteristics of advanced scientific research instruments, in particular the need for the use of many new principles, new methods and new technology independent research and development of the instrument, such an instrument is not ready to buy, even if there is a similar need to buy back and then upgrade and system integration. Obviously, if we don't pay attention to the development of the instrument, we can easily lose a key position in the experimental method.
To form a high-end scientific instrument R & D effective traction, on the one hand, the research work to go beyond the current tracking imitation stage "minor" level reached leading international "first-class" level; on the other hand, instrument R & D level to go up, to help you establish confidence in the obstetrical Instrument Research.
Two less investment and policy
At present, the development of the instrument is not enough, and it is not balanced, so "money" is bound to long-term development work.
We should note that, in addition to direct investment, currently used in the purchase of equipment on the money, there is a part of the actual use of research and development, because if domestic research institutes can spend more money for the purchase of new research instruments, can make the innovation of domestic research instruments - R & D - sales to form a smooth virtuous circle, such as can make enterprises willing to invest large sums of money in research and development, such as R & D and production team is also easy to stable, natural will be very favorable for innovation. |
