粗糙表面的分形参数表征

Fractal Characterization of Rough Surface

为客观，真实地描述粗糙表面的轮廓，应用分形几何的观点，提出一种新的表征参数一分形参数，并将其和传统的表征参数进行了比较，可看出该参数能更好地描述粗糙表面。

To describe profiles of rough surface objectively,fractal geometry theory is used and a new parameter is put forward in this article. The comparison shows that a new parameter can describe rough surface better than traditional parameters.
