Coaxial video transmission technology theory and practical application - Coaxial transmission, video - broadcasting industry
Coaxial cable is an ultra-wideband transmission media, from DC to microwave can be transmitted. Coaxial transmission electromagnetic theory is the theoretical basis, and general electrical circuit theory has important differences. Such as a cable connection using wire, shield welding, respectively, twist, and as with the "three links" Video Signal distribution, electrical circuit from the point of view this is reasonable, but from the perspective of a coaxial transmission theory of error. Then if the cable manufacturers to reduce the cable attenuation, the SYV75-5 0.75-0.8mm solid cable's core wire, to 1.0mm, the following reasons: physical foaming cable wire is 1.0mm, solid cable can also be made 1.0mm, as if I could choose R ...
Future Development of China's transmission technology - transmission, technology, automobiles - Hardware Industry
Auto transmission is very important to a configuration, the car's handling, comfort and fuel economy have played a very important role, which accounted for 7% of the cost of automobile manufacturing. As China's automotive consumer awareness of the rise of the automobile, the transmission has started to affect consumer behavior. In the past 10 years focused on research and development of our engine technology, transmission will most likely be hot the next 10 years research and development. The transmission will become the development trend of concern to hot.
On the role of Jane infrared temperature sensor - sensor - Electrical industry - China CRI Tester
Any object is issued by the electromagnetic radiation, such electromagnetic radiation can be infrared temperature sensor. When the object temperature changes, their radiation out would change the wavelength of electromagnetic waves, infrared sensors that can convert the wavelength of the temperature changes, in order to achieve monitoring, temperature measurement purposes.

AMT-made heavy-duty truck production,transmission core technology is still missing
The end of 2008, China Machinery Industry Federation said Zhang Xiaoyu, executive vice president, China's auto industry has made great progress though, the product continuously improve international competitiveness, but some core technologies with foreign countries there is a big gap. Automatic transmission is one of them. Since no real industrialization, the situation is still in control of others.
