Lose momentum and your forward thrust will be curtailed. If you ingest the animosity and acrimonious threats of the nay sayers you will be discouraged, and indeed that is their controlling motive.
如果你接受那些充满敌意或尖刻威胁之谔谔之士的话，你将会丧失勇气，而让他们控制的动机得逞。

The alternate roller bearing in FAG bearing, can bear at the same time come from each direction loading like axial, thrust or momentum loading.
FAG 轴承中的交叉滚子轴承，能同时承受来自各方向荷重（如轴向、推力或动量荷重等）。

Under the same wall heat condition, with the increase of momentum correction coefficient, viscosity loss of the nozzle increases, but thrust and specific impulse decrease.
