介绍了激光散斑的形成及其统计性质，拍摄大量不同加工工艺、不同表面粗糙度标准样块的散斑图像，基于激光散斑图像的灰度共生矩阵及惯性矩、角二阶矩、熵、相关性4个参量，对图像进行了纹理分析。

Engine, this paper found out that the antigalling abilities for parts being tested although quite smooth, even with quenched and ground surfaces were not too high, while the antigalling abilities were quite higher for those surfaces more rougher than the former but possess fairly big negative contour skewness RSK and considerable large mean spacing Sm of profile micro-inequality.

本文通过SRV 试验、Timken 试验和发动机挺杆的台架试验，发现了试件尽管很光滑，甚至是淬硬后精磨的表面的抗擦伤能力并不高，而粗糙度比前者高，但具有相当大的负轮廓偏斜度Rsk ，且具有相当大的轮廓微观不平度平均间距Sm 的表面具有较高的抗擦伤能力，这是由于它们具有较好支承面及众多"微油池"有利于润滑的结果。

Using fuzzy roughness and local operator to update the membership function of FCM algorithm.

使用局部模糊粗糙度和待定算子来更新FCM算法中的隶属度函数。

It is feasible to overgrow mesoporous MCM-41 on the rough surfaces of the grains. The obtained samples possess the ordered hexagonal mesoporous structure of MCM-41-type molecular sieves. Mesoporous molecular sieves (denoted as MZ-B) with ordered hexagonal structure have been successfully synthesized by the assembly of the precursors from filtrate of alkali-treated ZSM-5 zeolite with CTMABr surfactant micelles in alkaline media based on S+I– static electricity route.

而碱处理ZSM-5沸石得到的滤饼为富含超细化颗粒的晶粒，且晶粒粗糙度很高，因此易于附晶生长介孔分子筛，得到的微孔颗粒表面附晶生长的介孔分子筛，具有很好的长程有序度，为六方排列的孔道结构。
