蚯蚓被踩也会动（指：被逼过甚，最温顺者也会反抗）。反相微乳液法合成耐温抗盐聚合物驱油剂

The resistance of surface flow has a reverse relation with Reynolds number. With the same Reynolds number, the resistance coefficient of surface flow is greater than that of laminar flow in open channel and increases with increased bed roughness.

坡面水流阻力与雷诺数的呈反比关系，相同雷诺数条件下，阻力系数比明渠层流阻力系数要大，且随床面粗糙度的增加而增大。

By use of the reverse? drive test on a chassis dynamometer, the transmission resistance is measured, and the model of the transmission resistance is established.
