一引言自从摩擦学这门新兴学科于六十年代中期问世以来,迄今已获长足的发展。随着摩擦学研究的广泛发展及其研究成果的广泛应用,各个工业部门包括医学工业部门均已获得巨大的效益。通常认为,摩擦学的研究对象是无生命机体如机械及其零、部件等。其实,有生命的机体同样存在着众多的摩擦学问题。例如牙齿咀嚼是一种摩擦现象;血液在血管中流动也是一 I. INTRODUCTION Since the advent of new disciplines of tribology, which came into existence in the mid-1960s, so far has been developed. With the extensive development of tribological research and the extensive application of its research results, enormous benefits have been obtained in various industrial sectors, including the medical industrial sector. It is generally believed that tribology is the study of non-living organisms such as machinery and its zero, parts and so on. In fact, the living body also has many tribological problems. For example, chewing teeth is a kind of friction phenomenon; blood is also flowing in the blood vessels
