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。

The increased interfacial roughness can enhance photocurrent and efficiency of the device.

表面粗糙度的增加将增强入射光在界面处的反射作用，增强入射光在激活层中的吸收，进而提高器件的光电流和转换效率。

Such failure is due to the accumulation of toner than age at first, so that the toner can not produce a position to enter the toner, and the waste toner in粉仓will continue to "squeeze" caused by "powder leakage" phenomenon, Then, as the toner contains纸灰, fiber and other filth, more rough, and long cartridge friction, and more tight, the pressure increases, eventually the surface of photosensitive film cartridge has been worn away, cartridge will be ruined.

产生这种故障的原因是起先废粉堆积过满，使再产生的废粉无法进入废粉创仓，而废粉仓中的废粉也会不断"挤"出来而产生"漏粉"现象，接着，由于废粉中包含着纸灰、纤维等脏物，较粗糙，与硒鼓长时间摩擦，而且越来越紧，压力越来越大，最终将硒鼓表面的感光膜磨掉了，硒鼓就损坏了。

The method of reading the line, arc, spine, tolerances, surface roughness and full messages of the part from DXF file generated by AutoCAD is mainly introduced. Based on the study of DXF, a program interface is developed, by which the data can be shared among different CAD systems. According to the different Characters, the respective tool paths are designed. And by a machine configure file, the General postposition process is deal with. On the research of thegeneral simulation technology that is based on the NC codes. By analyzing the characteristics of the CNC system and the NC codes, a set of general simulation interface is developed.

本文主要介绍如何从AutoCAD生成的DXF文件中读取直线、圆弧、样条曲线、尺寸公差、表面粗糙度等信息及零件的全局信息，结合回转体零件的特点，通过对应用广泛的DXF的深入分析，建立了与不同CAD系统实现数据共享的编程接口；根据零件的不同加工特征提出了相应的走刀路线，并通过机床配置文件，初步实现了通用后置处理；研究了数控系统和NC代码的特点，建立了仿真通用接口，并提出代码翻译地基本思路。
