分析了密封系统中硬对偶件表面粗糙特性对密封系统工作性能的影响，揭示了在相对运动密封零件表面间摩擦学过程中出现的微观曲路密封效应和微观跑合效应，为通过控制密封系统中硬对偶件表面加工工艺以形成优秀的表面形貌，来提高密封系统的工作性能提供了新的思路和概念。
The influence of surface roughness on the performance of the sealing system was analyzed. The microscopical sealing effect and microscopic running effect appeared during the tribological process of the relative moving seal surface were revealed. In order to control the performance of the sealing system, In the hard pair of surface processing technology to form a good surface morphology, to improve the performance of the sealing system provides a new way of thinking and concepts.
