用 IFS 分形插值函数虚拟材料表面形貌的探讨

Approach into the Constitution of Virtual Material Micro Surface Topograply by Using IFS Fractal Interpolation Function

研究了构造分形几何图形的一种重要方法：迭代函数系统（ＩＦＳ）。用ＩＦＳ分形插值函数在计算机上生存了材料表面轮廓曲线及曲面，对表面形貌的虚拟结果进行了分析。最后指出，基于分形学的表面形貌虚拟是一个很有工程应用前景的研究领域。

An important method for constitution of fractal geometric graph——Iteration Function System(IFS)is investigated in this paper The material miero-surface topography can be analysed by using IFS fractual interpolation function to form configure curves and surfaces in a computer At last it is pointed out that the research on surface topography based on the fractral geometric method is very useful in engineering application
