Above behaviors of frictionnoise were explained with the energy dissipation principle.
提出了用能量耗散原理来解释上述现象。

Teflon Piston-ring integrated with piston, not only reduce the friction and noise, but also avoid inner-leakage.
特氟龙材料的活塞环与活塞熔接成一体不仅减磨效果好，同时能减少噪音防止内泄。

The results show that the wavelet denoising method can effectively restrain the noise in friction and sudden unbalance signal, and reserve the fault character information in the signals.
