1、The frictional force between a particle and fluid counterbalances the weight of the particle.
顆粒與流體之間的摩擦力與其重量相平衡。

2、Friction prevents it from doing so so there's going to be a frictional force in this direction.
摩擦力則阻礙下滑，因此存在，此方向的摩擦力。

3、So I know what the frictional force is given by this result.
由此我得到，摩擦力的大小。

4、An analytic model including effects of frictional force at movable supports is suggested.
文中建議了考慮活動支座摩擦力影響的簡支梁橋整體分析模型。

5、The frictional force between fibres and card wires is measured experimentally.
本文對纖維與梳針間的摩阻力進行了實驗測定。

6、How does the frictional force do that?
摩擦力是怎么做的？
