We make a distinction between static friction coefficients and kinetic.

摩擦系数也分为，“静摩擦“和“动摩擦“系数。

The relationship between static and dynamic friction coefficients of the rigid blocks with smooth surfaces has been studied preliminarily by means of a dynamic test of rigid blocks in this paper.

本文通过刚块动力模型试验，对具有光滑表面刚性块体的动、静摩擦系数关系进行了初步探讨，并以模型试验结果验证了离散元数值模型的正确性。
