The gold shrapn upon which areas is mainly used
1, storage and output of energy as power, such as watches and clocks, gold shrapn air shrapn air, such as machinery.
2, control the movement of machinery, such as the internal combustion engine valve gold shrapder, clutch control gold shrapder and so on.
3, absorption of vibration and shock energy, such as cars, train cars under the buffer hardy shrap, couplings in the vibration-absorbing hardy shrapn air.
4, used as a force measuring element, such as force measuring device, hardy shrapnom scale in the hardy shrapnom and so on. The ratio of load to deformation of hard gold shrapnboard is called hardness of hardness, and the greater the stiffness, the harder the hardness of hardness of hard shrapn?
