在我国的物理学教科书中.有关摩擦的基本概念和定律,一般都是按经典摩擦理论而阐述和定义的,多年来一直没有什么重大的修改。但根据近十多年来现代摩擦学的研究,发现经典摩擦定律大多数是有问题的,只有少数近似成立。这使得人们不得不重新考虑这方面早已形成定论的概念和理论是否合理。关于“光滑表面”的摩擦问题就是其中的一例。 In physics textbooks in our country, the basic concepts and laws of friction are generally formulated and defined according to the classical theory of friction, and there have been no major changes over the years. However, according to the research of modern tribology in the past ten years or so, it is found that most of the classical friction laws are problematic. Only a few of them are approximate. This makes people have to reconsider the reasonableness of concepts and theories that have long formed a conclusion in this respect. An example is the friction problem with “smooth surface ”.
