liquid lubrication

基本解釋

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(rùn)滑油。
The lubrication of vacuum roll-element bearings include liquid lubrication and solid lubrication.
真空滾動(dòng)軸承的潤(rùn)滑包括液體潤(rùn)滑和固體潤(rùn)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(yùn)動(dòng)部件間存在液體潤(rùn)滑作用造成的能量損失而引起，也可因活塞迫使液體穿過(guò)小孔造成的能量損失而引起，像汽車避震器那樣。
