润滑

In chapter 4, the effects of orientation of rough surfaces on the lubrication behaviors of frictional pairs operating in the isothermal condition were studied and found that: the conclusion that the hydrodynamic load carrying capacity of transversely oriented surface is better than the isotropic surfaces is tenable only if the minimum clearance is relatively large, but the longitudinally oriented surfaces always decrease the load carrying capacity..

第四章在等温条件下，计算了粗糙表面的纹理方向对摩擦副润滑性能的影响，发现横向纹理表面具有比各向同性表面更大流体动力承载能力只有当最小间隙较大时才能显示出来，而纵向纹理表面总是使得流体承载能力下降。
