The results show that although the profile w ear of the surface is not beneficial to the lubrication, the asperity wear does. In consideration of coupling wear of profile and asperity, the minimum film thi ckness increases in a certain worn height. Therefore, the wear of asperity is be neficial to lubrication in this region.

分析结果表明：在重载条件下表面轮廓磨损不利于润滑，而表面微突体的磨损则有利于润滑；当同时考虑表面轮廓和粗糙度时，在一定磨损高度内，磨损显著增加润滑膜的最小膜厚，从而有利于润滑。
