摘要: Surface roughness has been a topic of considerable interest within the engineering community for many years, primarily because surface affects frictional properties and wear sliding surfaces, electrical contacts, stiffness machine parts (Thomas, 1982). Most studies however concentrate on surfaces that can be described using Euclidean geometry rather than type by fractal geometry. The reason is almost all man-made natural ones, mimic simple geometric forms, such as spheres, cylinders, planes, or their derivatives. shapes have great practical importance; example, ball bearings function well they are close approximations to while mirror provides an undistorted reflection it approximation plane.
