仿射性 meaning in Chinese

affinitaet affinity

The fractal theory provides an important method in study of irregular objects of self - similarity and self - affinity
摘要分形理论是分析和研究自然界中具有“自相似性” 、 “自仿射性”不规则形体的重要手段。
But in the nature rough surface is not pure period or completely random . as far as statistics view is considered , one - dimensional ? two - dimensional random rough surface , also all exist the likeness and the self - affine in the certain degree , and have a certain fractal characteristic . we adopt the fractal theories that can describe actual rough surface betterly . by the fractal theories the thesis acquire one - dimensional ? two - dimensional random rough surface model , and study scattering characteristic of light on one - dimensional ? two - dimensional fractal rough surface
从统计意义上来讲,一般的一维?二维随机粗糙面,在一定的标度之间也都存在着自相似性或自仿射性,具有一定的分形特性,采用分形理论能更好地描述实际的粗糙表面。
