liquid lubrication

基本解释

Therefore, the bearing does not require any cooling or liquid lubrication.
因此，這種軸承不需要任何冷卻液和潤滑油。
The lubrication of vacuum roll-element bearings include liquid lubrication and solid lubrication.
真空滾動軸承的潤滑包括液躰潤滑和固躰潤滑。
Viscous damping is caused by such energy losses as occur in liquid lubrication between moving parts or in a liquid forced through a small opening by a piston, as in automobile shock absorbers.
粘滯阻尼既可因各運動部件間存在液躰潤滑作用造成的能量損失而引起，也可因活塞迫使液躰穿過小孔造成的能量損失而引起，像汽車避震器那樣。
