摘　　要：目前普遍使用的表面形貌评定参数不能够准确反映轧辊和钢板表面的承载性能和储油性能．本文提出了二维轮廓和三维表面的功能特征参数,并给出了计算方法．通过与表面粗糙度的比较以及对电火花毛化轧辊表面形貌的分析,结果说明了表面形貌功能特征参数使表面的承载性能和储油性能分析更为具体和准确．The traditionally used parameter for accessing the surface such as surface roughness has a very limited value in relating the functional properties of bearing and lubricant retention capabilities to the surface of rolls and steel sheets. This paper proposed some functional characteristic parameters of 2-D profiles and 3-D surfaces and presented their calculating methods. By comparing with surface roughness and analyzing the surface of electrical discharge textured rolls with these parameters, it is proved that these parameters more concretely and exactly show the functional properties of surface topography.
