摘要
Motif方法是一种新的表面形貌评定方法 ,通过设定不同的阈值 ,可以将波度和表面粗糙度分离开来 ,它强调大的轮廓峰和谷对功能的影响 ,在评定中选取了重要的轮廓特征 ,而忽略了不重要的特征。介绍了 2维 Mo-tif的参数和合并条件 ,然后对 3维 Motif方法的定义、评定参数及算法等进行了综述 ,并提出了推广这一评定方法需要注意的问题。
Motif method is a new assessment method of surface topography. By setting various threshold values, surface roughness can be separated from waviness. The method stresses large peaks and valleys of the surface profile and selects important profile characteristics, but ignores those unimportant in topography assessment. Firstly, the parameters and combination conditions of 2D- Motif are discussed. Then, the definitions, parameters, and algorithm of 3D-Motif are summarized. Finally, some problems worthy to be studied in spreading the method are proposed in this paper.
