Experimental instruments are the instruments used in natural science experiments, mainly physics, chemistry, and biology. The development of experimental instruments should be regarded as a difficult task by ordinary people, but it was held recently in Guangdong Province. In a primary and secondary school competition, after 90, the experimental equipment developed by the teachers successfully won the provincial first prize, solved the teaching difficulties in the experiment, and has applied for a national patent.
In the just-concluded Guangdong Provincial Middle School Physics and Primary Science Experiment Teacher's Experimental Operation and Innovative Skills Competition, the electric power experiment explorer developed by Cheng Huizhen, an experimental school teacher in Longgang District of Shenzhen City, Guangdong Province, won the first prize in the province. The only provincial first prize will be actively promoted in the school. In addition to the award-winning electric power experiment inquirer, Li Peidong's work “Series of Innovative Experimental Equipment for Microbiological Observation of Microorganisms” has also achieved impressive results.
Why can I, as a teacher who has never before been exposed to experimental instrumentation R&D, successfully develop experimental instruments that can be produced in large quantities? Xiao Bian thinks there may be three reasons.
First, market demand determines production. According to the introduction, most of the microscope equipment used in most elementary schools is relatively backward. The experimental observations are not ideal. The existing teaching equipment of junior middle school physics cannot demonstrate the change of electric power. In order to promote primary and secondary schools In the face of these problems, the Bureau of Education also organized several activities to promote the research and development of the instrument. As the first line of the problem, experimental teachers naturally have more understanding of the instrument. For instrument manufacturers It is said that the most important thing is to be able to see the needs of the market. At present, facing the huge gap in the experimental instrumentation of primary and secondary schools, producing the instruments and meters that the market really needs is the most important thing.
The second is that most companies pay less attention to the basic experimental instrumentation. When quantifying the actual electric power, Chen Huizhen cited the current and voltage electric power combiner. But for digital display current, voltage, The module of electric power, the instrument purchased at that time would not be used at all, and even the specification could not be read. At present, faced with the needs of advanced enterprises in foreign enterprises and various advances in the production process, China's instrumentation research and development are all moving The development of high-precision directions can certainly promote the continuous advancement of science and technology in China. However, it is also very easy to encounter two problems. First, the scientific research results are grounded. Second, it is easy to overlook the construction of infrastructure. We really need instruments, but we can't relax the research and development of practical and basic instruments.
The third is the hard work of the developers. R&D has always been a difficult task. We need to keep a close eye on the experimental results. On the road to R&D, we have never had a smooth sailing. In fact, this secondary education was developed through our own efforts. The utility instrument is also a great incentive for the instrument research and development companies. When faced with a foreign well-known instrument company, it is not necessary to mimic it. Just find the pain points of the industry and calm down and develop practical instrumentation. Can become stronger and stronger.
On the road to instrumentation R&D, in addition to high-precision experimental instrumentation, there are many basic requirements. For some small instrumentation companies, R&D of instrumentation does not have to be focused on high-end areas, if only blindly The pursuit of high precision is often laborious and thankless. Secondly, for the education industry, the basic R&D of experimental instrumentation has extraordinary significance. It is conducive to cultivating students' extensive interest in R&D of instrumentation and further improvement of the instrument. Instrument industry influence and popularity.
