In the seed test, a few grains are indispensable, because in tests such as 1000-grain weight and seed germination rate, they are based on 1000 seeds or 100 seeds, but the number of grains is boring and there is no The technical content can speak of, so spending too much time on this aspect does indeed have a loss of sense, and there are still a few or most problems with manual counting. As a result, the use of counting instruments to perform seed counting becomes more and more. It is necessary. Steel frame electric bicycles, processing performance, chromium-molybdenum steel is the oldest bicycle materials, the longest of its research, the processing technology has been developed to a very stable level. 2. Strength According to the conclusion of the car, it can be concluded that car enthusiasts can draw the conclusion that the strength of the same volume steel is much larger than that of aluminum alloy and titanium alloy, so the strength of qualified steel frame can be reassuring. 3. Take a comfortable, good steel elastic steel made of metal, can absorb the vibration when riding. Therefore, the steel frame will not be as uncomfortable as the aluminum frame, especially for the travel frame. 4. Steel metal fatigue stronger than aluminum, so the same conditions of use, the life of the aluminum frame longer life. Of course, the steel frame also has its insurmountable shortcomings: 1. Light weight, today in the pursuit of lightweight equipment, the quality of 7.8g / cm3 steel so that everyone does not encourage him. Although light steel construction, while pumping pumping technology wall is very thin, but the weight of the steel is difficult to reduce to 1600 grams or less. Many aluminum frame weighs only about 1400 grams. This is a competitive framework, rarely seen the reasons for the steel frame. 2. Rusted, relative to other materials, steel is relatively easy to rust. Rust can drastically reduce the strength of the steel, shortening its service life. (Such as BEARS these frames in order to prevent the problem of rust to the framework of the new tube coating), so we must take various measures to prevent rust.

The benefits of seed counting using the counting instrument are mainly in three aspects. The first is to liberate manpower, free the staff from the tedious and tedious work, and reduce the labor intensity of the staff; the second is to greatly improve the The efficiency of seed grain, especially when a large number of grains work, the number instrument can be used for a large field; the third is to reduce the error of artificial grains, and improve the accuracy of the number of seeds. It is precisely because of the superior performance of the grain analyzer in counting several grains. In the seed inspection institutions, production companies or related research departments, the application of the grain analyzer is very extensive.
Actually, the counting instrument is not only used for seed testing. It can also be used in many other aspects, such as agricultural breeding. With the development of the agricultural industry, the work of breeding excellent seed varieties is becoming more and more important, but For the cultivation of new seed varieties, many of them are obtained through the selection of superior varieties. Therefore, these seeds also need to be tested, and the application of the counting instrument can effectively alleviate the large number of seed samples in the breeding work and the workload is large. Problems have greatly shortened the cycle of breeding, saved time for breeding, and cultivated a number of excellent seed varieties. Applying these new varieties to production has played an important role in both agricultural breeding and the progress of the agricultural industry. effect.
