【摘要】 通过对表面轮廓分形和分形曲线的基本概念阐述,针对目前常用于表面轮廓分形维数的五种计算方法进行比较、分析和评价,认为结构函数法计算的分形维数偏差较小,是目前进行表面轮廓分形维数计算的一种可行方法,并为粗糙表面分形维数计算提供了方法和思路。更多还原

【Abstract】 The basic concept about fractals and the fractal curves are introduced. Five methods currently used for computing the fractal dimension of rough profiles are illustrated. By compared with the five methods, the structure function method dimension presented higher accuracy and less fluctuation of the computed fractal dimension. This method is an available computation method for rough surface profiles to describe the complex characteristics of rough surfaces.更多还原
