粗糙度

The simulation results of smooth metal surface with roughness of 1.6 μm accord with the experimental data very well, but the simulation results of rough metal surface with roughness of 6.8 μm disaccord with the experimental data.

对于表面粗糙度为6.8 μm的较为粗糙的金属表面，仿真出的结果和实验中获得的数据相差较大。

A relationship of the roughness parameters of diffusing surface strongly depend on the space correlation function of quasi—ideal imagine system has been confirmed and a new method for evaluating roughness has been proposed. In Chapter 4, the statistical properties of superposed dynamic speckle from a rotating diffuser have been investigated under double Gaussian—beam illumination.

同时，本章还证明了准理想外差成像系统动态散斑的空间相关与表面粗糙度参数之间有很强的依赖关系，在此基础上提出了一种新的工程表面粗糙的测量方法和计算机仿真的结果。

In Chapter 3 relaxation in growth with a conservation law is studied, and reduced roughness of the surface due to the effect of relaxation is found. The last chapter includes discussions of point defects in conservational surface growth.

第三章研究了守恒界面生长中界面弛豫效应的影响，发现弛豫作用使得守恒生长的界面粗糙程度下降；第四章研究了杂质点缺陷的存在对生长表面的影响，发现存在于生长的活跃表面层中的点缺陷会使表面的局域粗糙度增加。

The objective of this research is to observe and characterize both the surface roughness and aperture of rock joints in combination with the mechanical and hydromechanical behavior of rock joints and to draw some significant conclusions from the observation and analysis.

本文的研究目标是通过观察和定量描述岩石节理面的表面粗糙度和间隙幅，建立表面几何粗糙特性和力学及水理学特性的关系，并从观察和分析中得出一些有意义的结论。本文的第一章简要介绍了研究背景、研究目的和内容。

Remove surface laitance and provide sound and textured surface.

使用地坪打磨机和无尘封闭手提磨机去除表面粗糙物，并提供涂装对表面所要求的粗糙度。

Surface laitance and provide sound and textured surface.

使用地坪打磨机和无尘封闭手提磨机去除表面粗糙物，并提供涂装对表面所要求的粗糙度。

Carry out surface preparation by Grinder and dust free self-enclosed portable grinder until to remove surface laitance and provide sound and textured surface.

使用地坪打磨机和无尘封闭手提磨机去除表面粗糙物，并提供涂装对表面所要求的粗糙度。

The crocking resistance of coatings film is tested by use of adhesive tape, sticking off or peeling off of the marks painted with waterborne or solventborne marking pens.

结果发现表面粗糙度和表面助剂的共同作用可有效防止记号笔对涂层的粘结，粗糙表面的涂层亲水、亲油性对抗粘结作用有较大的影响，涂膜在水浸泡前后的抗粘性效果表现不同。

As illustrated, Raman activity varies with conditions changing in roughening processes and the most reasonable condition for roughening was indicated.

初步的实验结果表明，采用机械粗糙和电化学氧化还原方法能够获得具有一定粗糙度的电极表面，但是该表面并不具有SERS活性。

Wall roughness and paint sheen can affect the lightness of any color. Smooth surfaces and gloss paints reflect maximum light to make a color seem lighter. Rough-textured walls and flat sheen paints hold more shadow and minimize the lightness of a color.

墙面的粗糙度和油漆的光泽度会影响任何颜色的亮度，平滑的墙面和光亮的油漆反射出的光使得颜色看起来更淡，粗糙的墙壁和屋顶储存了更多的阴影从而减弱了颜色的亮度。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
