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。

However, the emissivity is affected by many factors, such as roughness. Simulation results for surfaces with different roughnesses are compared. It is found that the effects of roughness on the bidirectional reflectance distribution function and normal emissivity are significant.

在实际应用中，物体的发射率受到很多因素的影响，粗糙度就是其中之一，通过比较不同粗糙表面的计算结果，发现粗糙度对二向反射分布函数和法向发射率的影响不可忽略。

In chapter 4, the effects of orientation of rough surfaces on the lubrication behaviors of frictional pairs operating in the isothermal condition were studied and found that: the conclusion that the hydrodynamic load carrying capacity of transversely oriented surface is better than the isotropic surfaces is tenable only if the minimum clearance is relatively large, but the longitudinally oriented surfaces always decrease the load carrying capacity..

第四章在等温条件下，计算了粗糙表面的纹理方向对摩擦副润滑性能的影响，发现横向纹理表面具有比各向同性表面更大流体动力承载能力只有当最小间隙较大时才能显示出来，而纵向纹理表面总是使得流体承载能力下降。

A model to describe the motion of contact line and dynamic contact angle on rough solid surfaces was proposed.

提出一个粗糙表面上移动接触线和动态接触角的数理模型：毛细数较低时表观接触线前缘存在极薄的前驱膜，表观接触线在"湿"固体表面上移动，不同于传统模型中认为表观接触线在"干"固体表面上移动。

The results show that although the profile w ear of the surface is not beneficial to the lubrication, the asperity wear does. In consideration of coupling wear of profile and asperity, the minimum film thi ckness increases in a certain worn height. Therefore, the wear of asperity is be neficial to lubrication in this region.

分析结果表明：在重载条件下表面轮廓磨损不利于润滑，而表面微突体的磨损则有利于润滑；当同时考虑表面轮廓和粗糙度时，在一定磨损高度内，磨损显著增加润滑膜的最小膜厚，从而有利于润滑。

Alloy of polyethylene of element of the methodological freeboard that make, titanium and sample of alloy of cobaltic chromic molybdenum, FITC of classics of cuticular grape coccus labels, the cuticular grape coccus that after sample of artificial and articulatory material is disinfected, vaccinal FITC labels, sample surface cent is slick surface and rough surface, every groups each 6 sample, brood the 24 orifice plate that contain bacterium and sample below 37 ℃ after Yo 30min, with fluorescent microscope observation, sample uses observation of scanning report lens.

方法制作超高分子聚乙烯、钛合金和钴铬钼合金试样，表皮葡萄球菌经FITC标记，人工关节材料试样消毒后接种FITC标记的表皮葡萄球菌，试样表面分为光滑表面和粗糙表面，每组各6个试样，将含有细菌和试样的24孔板在37℃下孵育30min后，用荧光显微镜观察，试样用扫描电镜观察。

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。

If using humidly hardener, the surface can be humid, but there should not be any panice. b the surface should be fastness, compact and smooth, without any sand streak, floppy shell, crack, comb,bug holes. Using light blasting spray to clean the unevenness and incompact raffle, and getting the appropriate roughness, filling the crack with HF61-30 mixed with fine sand. C the surface must be clean, and have no oil stain.

如采用湿固化涂装，则表面可潮湿但不能有浮水。b水泥表面应坚固、密实、平整，不能有起砂、起壳、裂缝和蜂窝麻面等现象，可采用轻喷砂法除去水泥面上的不平整和不结实的杂物，并使其具有一定的粗糙度，对裂缝可使用HF61-30添加适量细砂填补。c表面必须清洁，须除去表面油污。

The surface roughness of these films were investigated by SEM and surface roughometer, and the dynamic clotting time and hemolysis rate of these different roughness micromagnetic field surfaces were tested.

测试了不同粗糙度的微磁场表面的动态凝血时间和溶血率，研究了微磁场表面的粗糙度对材料血液相容性的影响。

When new concrete with higher strength grade is cast, the higher the roughness of old concrete fracture surface is, the higher the interfacial bond strength of old-new concrete is.

结果发现：用分数维来表征老混凝土表面的粗糙度，其预测结果精度较高；在粗糙度较高的老混凝土表面上浇注较高强度的新混凝土，获得的新－老混凝土界面粘结强度较高。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
