Scientists now believe that some of the force of friction is due to attraction between the molecules of one surface and those of the surface sliding over it.

现在科学家们认为有些摩擦力是由于物体表面的分子和另一物体表面游动的分子之间的吸引力所引起的。

Friction force measurements during unlubricated pin-on-disc sliding tests, profilometry and SEM analysis of wear tracks are used to determine the wear behavior quantitatively and qualitatively.

摩擦学性能由销一盘式试验过程中的摩擦力数据和对磨痕的表面轮廓仪和扫描电镜分析作出定量、定性的评价。
