What are the gaps between domestic instruments and imported products?

"Before the experiment, we would very much like to buy home-made equipment. The price is definitely worthwhile, but according to our experience, it will be very easy for domestic equipment to be used after a period of time. Therefore, we would rather spend a little more money to buy it for longer. Imported instruments," said one scientist engaged in virus research. Presumably this is also the common feeling of many instrument users in China. It can be seen that there is an undeniable gap between Chinese instrumentation products and foreign products. Then, what are the gaps between domestic instruments and imported products?

In March 2007, the China Association for Science and Technology published the survey results of their organizations: The main analytical instruments in China's instrumentation and instrumentation, and more than 90 analytical instruments being applied in the society. More than 20 kinds of products can be produced in China. 1/3. Among them, there are about 80 kinds of special instruments for life sciences, and only 6 kinds of special instrument products for life sciences have been commercialized in China. About 10 types are currently under research, which is far from market demand. This is a quantitative gap.

In terms of technology, the existing domestic middle- and low-end products can be replaced with imported products, and the reliability index of high-end products, that is, the average time between failures and foreign products is about 1-2 orders of magnitude.

In terms of measurement accuracy, existing domestic products and foreign products generally differ by one order of magnitude. Because China's basic technology and manufacturing process of the instrument are not adequately studied, some key technologies that affect reliability, such as precision machining technology, sealing technology, and welding technology, have not yet been well resolved, resulting in products, especially high-end products. The performance is not stable enough and reliable.

In terms of function, at present, the degree of intellectualization of foreign production is quite high. Through the digital processing of original information, the influence of external interference on information is better eliminated, and the environmental resistance and measurement authenticity of the product are improved. However, the current level of domestic product intelligence is still relatively low.

In addition, the networking of products has entered a practical stage in foreign countries, and our country is basically in its infancy, thus making the product's performance and function backward.

According to experts, the update cycle of current foreign products is about 2-3 years. The reserves of new technologies can often be advanced to 10 years. However, Chinese companies often introduce new technologies to update their products. They cannot be well-digested after introduction, and there are few original results in the development of new products. Some products that adopt new principles are still in a blank state in China. Although the research institutes have made achievements in tracking new technologies, it has been difficult to integrate industrialization with enterprises, leading to a long cycle of product technology renewal.

In addition, domestic instruments lack dedicated solutions developed for use. In recent years, the development trend of measurement control and instrumentation in foreign countries is to develop software products in which instrumentation and application objects are tightly integrated, and ultimately provide users with personalized solutions. For example, for the 6×10'kW thermal power unit's unit performance calculation software, optimization software for the refining process, and graphics processing software for medical instruments, domestic companies have not yet formed an industry in this area.

The foundation is weak, and the system mechanism has not been smoothed. Experts involved in the survey have stated that instruments and meters belong to the high-tech industry, and China's industrial development depends on the advantage of low labor costs, and this advantage is difficult to play in the instrumentation industry.

They believe that there are several reasons for the gap between China's instrumentation products and foreign countries. The operating mechanism of China's enterprises still cannot fully meet the requirements of the development of the market economy. In the process of development, a number of key enterprises invested by the state are faced with a grim situation of product aging and the loss of technicians. After restructuring, although there is improvement in production and operations, the capacity for scientific and technological innovation is still not enough; a group of mechanisms are innovating and operating. Flexible private enterprises are gradually becoming new bright spots. However, the vast majority of companies are small and medium-sized enterprises. They are small in size, and most of them have not yet mastered advanced core technologies. They have few innovation results and cannot compete with foreign large companies.

First of all, the integrated system, policies, and policies of production, learning, and research in the country as a whole have not been formed. The rate of conversion of innovation results is low, and the application of technology is poor. In the early period of reform and opening up, the instrumentation industry and foreign countries had a wide gap, and companies generally sought technology sources outward. Although there have been changes in recent years, some companies have come to the fore, but overall, the combination of independent innovation technology achievements and applications is not much. Big business growth is difficult.

China's scientific research institutions involved in measurement and control technology and related instruments have many scientific research achievements, but their practicality is poor. The depth and intensity of research on related manufacturing and manufacturing technologies, especially core technology, are insufficient. The amount of work for secondary development is large, and the conversion rate of results is low. High and mid-range instrument products and systems involve application technologies with a certain depth in different fields. Foreign companies have specialized departments and have experienced application talents. China’s instrument and meter companies are often unfamiliar with large-scale engineering processes and lack the integration capabilities of application technologies. . Therefore, it is difficult to produce high-end products.

Second, there is a lack of a strong national research support system. The instrumentation industry has many varieties and small batches, and it requires long-term, unremitting investment. However, at present, the country’s investment channels are scattered and it is difficult to focus on the focus. Businesses can neither compete in accordance with the rules of market economy like foreign companies, but also lack strategic investment in research resources. At the same time, the market environment needed for the marketization of new technologies has not yet been perfected.

Experts said that “because the institutional mechanisms are not straightened out, naturally the instrument and meter industry in our country lacks high-level composite talents, and lacks comprehensive talents who are familiar with and master the intercrossing of various disciplines. Instrumental science and technology not only involve a wide range of disciplines, but also only People who can discover, utilize and integrate various new scientific and technological achievements such as new principles, new concepts, new technologies, new materials, and new technologies as soon as possible can design and manufacture world-class measurement and control and instrumentation products. The development of the industry is undoubtedly an important reason for the gap between domestic instrumentation and imported products.
