摘　　要：活塞环与缸套相互接触并发生相对滑动,则出现摩擦,导致两摩擦表面的材料不断损失,即磨损,同时也使材料表面的温度升高。因此,摩擦、磨损和温升往往是同时出现的。研究三者的关系,对于减少活塞环与缸套的摩擦、控制其磨损、降低接触部位的温升是十分有用的。从热力学第一定律出发,建立了上述三者的定量关系,并分析了不同摩擦状态下各个量的相互影响。When the piston and cylinder contact each other having relative sliding,friction appear,temperature of the contact surfaces rises and wear occurs. Since the friction,the wear and the surface temperature rise usually take place together,the study on these three factors becomes very useful for diminishing friction between the piston and cylinder, controlling wear and decreasing the temperature of the contact area. This paper established the quantitative relations of above three mentioned factors and analyzed the parametric effects of each other in different friction states using the first thermodynamic law.
