表面粗糙的

It is shown that a "labyrinthic" structure with mass cuboid plateaus and caves is formed on the surface of aluminous sheet.

研究结果表明，表面微细粗糙结构对表面的超疏水性起到了决定性作用，是制备超疏水表面的关键所在。

Through simulating the speckle intensity distribution in the far field of a random rough surface,we compute the degree of angular speckle correlation by substituting spatial average in speckle pattern for conventional ensemble average,and determinate the surface roughn.

通过模拟计算随机粗糙表面的远场散斑场，以散斑图面上的空间平均代替常规的集平均来计算角度散斑相关系数，并应用集平均的数学模型反演粗糙度参量。

ABSTRACT In this paper, integrated with surface topography, asperity contact behaviour and fluid mechanics, the lubrication of real engineering surfaces and their rubbing behaviour are described in experiment and theory.

本文结合实际工程表面的形貌特征、表面微凸体接触力学性质和润滑力学性质对粗糙表面的润滑及摩擦特性进行了系统的实验研究和理论分析。

Finally steel balls millstone covering with Ni-Fe-diamond composite electro-brush plating film is produced successfully.Secondly, the steel balls millstone is used to grind steel ball in ones steel ball factory, and process flocculus the steel balls that possess reticulate veins surface.

然后利用制成的钢球研磨板对钢球进行超精磨削加工，加工出了表面具有网状纹理形貌的"绒面"钢球，利用仪器测量钢球表面的粗糙度值达到了0.015μm，表面波纹度值达到了0.006μm，圆度达到了0.010μm，球批直径变动量小于0.015μm。

Cutting phaseWhen the protruding peak of holystone surface and coarse raceway surface is contacted, because osculatory area is lesser, the pressure on unit area is greater, below constant pressure action, holystone gets above all of workpiece " a traditional method of indicating the pronunciation of a Chinese character by using two other Chinese characters is cut " action, make the part of holystone surface grinds bead to fall off with disintegrate, show a few new grind bead and blade edge ......

切削阶段磨石表面与粗糙滚道表面的凸峰接触时，由于接触面积较小，单位面积上的压力较大，在一定压力作用下，磨石首先受到工件的"反切削"作用，使磨石表面的部分磨粒脱落和碎裂，露出一些新的锋利的磨粒和刃边。与。。。。。。

The laser used for Raman excitation in the experiment would assist the etching process of Si in DHF and roughen the silicon surface.

研究了DHF腐蚀硅片时表面氢终端的变化过程，并指出表面微粗糙度随腐蚀逐渐增加。

This shear force increased with the roughness of the surface.

镀层表面越粗糙，垂直于氧化膜的切应力分量越大，表面裂纹和锡须生长也越多。

Expect for a few pittings,the N+1-implanted surface had a best fineness (average roughness Ra≈4.2nm), close to the unimplanted original surface.The N+2-implanted surface had a black dendritic area,and had a poorer fineness (Ra≈16nm).While in the N+10-implanted surface appeared a ripple structure,with the poorest fineness (Ra≈40nm).

但其表面形貌各异：N+1注入的表面除存在少量点蚀坑外，光洁度最高(平均粗糙度Ra≈4.2nm)，接近未注入前的原始表面(Ra≈3.5nm)；N+2注入的出现黑色枝状区域，光洁度次之(Ra≈16nm)，而N+10注入的则出现&波纹&状结构，光洁度最差(Ra≈40nm)。

On smooth surface, cells became gradually attached on substrates at early phases; on rough-surface materials, thin and long filopodia between the cells were connected to the substrate.

在光滑表面，细胞从初期渐渐贴附於基材；在粗糙表面镀层上，细胞与细胞之间有细长的假足丝相连接至基材上。
