摘　　要：本文从分子之间的相互作用的角度讨论了滑动摩擦力的微观机理.两个物体相对滑动时,在接触面上的分子之间主要存在两种作用:分子之间的吸引力和分子相互碰撞时的冲力.这两种力的宏观效果就是滑动摩擦力. 作者推导出这两种作用的理论公式,并计算了几种金属材料的滑动摩擦系数,与实验得到的数据比较接近.The author discusses the micromechanism of frictional force as viewed from reciprocity. There are two functions among molecales on the contact surpace sach as the attractive force among molecules. The macrocospic effect of the two forces is sliding frictional force. The author infers theoretical formula of the two functions and calculates the sliding frictional coefficieuts of some metallic materials. The data calculated approaches those obtained from experiments.
