| 摘 要： | 用Weielstxass－Mandelbrot函数产生了一维的分形表面，在几何光学适用的范围内研究了这些表面的光散射特性．发现分形线数D越大，通常被认为越粗糙的表面，其光散射的角分布反而比D小的表面更集中．文章最后解释了这种现象的成因．

| Abstract: | One-dimensional surf ares are produced by Weierstrass-Mandelbrot Function. Lightscattering characteristics of these surfaces are studied under the condition of geometrical optics.It is found that surfaces with large fractal dimension D, which were thought to be more ragged,have a sharper scattering distribution than those with small D. Explanation of this result is alsopresented. |
