1·So there is also a frictional force.
所以这个是摩擦力。
2·How does the frictional force do that?
摩擦力是怎么做的？
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·Pressure and the appropriate frictional force is determined.
压力和适当的摩擦力的测定。
5·The frictional force between fibres and card wires is measured experimentally.
本文对纤维与梳针间的摩阻力进行了实验测定。
6·And that now must be the frictional force, because NP is still the frictional force.
这肯定是摩擦力，因为NP还是摩擦力。
7·So that means that N of P must be in magnitude the same as the frictional force.
这意味着PN必须,在大小上,与摩擦力相同。
8·An analytic model including effects of frictional force at movable supports is suggested.
文中建议了考虑活动支座摩擦力影响的简支梁桥整体分析模型。
9·Friction prevents it from doing so so there's going to be a frictional force in this direction.
摩擦力则阻碍下滑，因此存在，此方向的摩擦力。
10·The frictional force between a particle and fluid counterbalances the weight of the particle.
颗粒与流体之间的摩擦力与其重量相平衡。
