1. The size of the peaks, or asperities, depends on the material and the method of surface finishing. 峰或突起的大小与材料和表面抛光方法有关。
2. In this paper, a three-dimensional measuring system for surface asperities is described, in which a microcomputer is interfaced to a stylus profilometer. 本文介绍采用触针式轮廓仪与通用微型机相连的表面三维形貌测量系统。
3. However, at higher angle of tooth-shaped asperities and under higher normal stress, the failure model II is found, which is in first tension but final shear failure. 在较高的法向应力下，含起伏角较高齿形节理面的非贯通节理岩体可能出现破坏模式II（先张拉后剪切破坏模式）。
4. When under the same speed, if the axle load gets weighter, the adhesion coefficient increases as the ratio of the mean asperities contact pressure to the total pressure becomes bigger. 相同速度下，轴重较大，粗糙峰接触压力占总压力的比值也越大，此时粘着系数也较大。
5. When under the same axle load, if the wheel rolling speed gets higher, the adhesion coefficient declines as the ratio of the mean asperities contact pressure to the total pressure becomes smaller. 研究发现：相同轴重下，滚动速度越大，粗糙峰接触压力与总压力的比值越小，导致轮轨之间的粘着系数下降；
