Compared with the graphite, the coefficients of friction of the RL-C/C are lower under the same load of about 0.08-0.12, and the increasing range of the volume losses are still lower than those of the graphite. Compared with the SL pyrocarbon material, the COF and the volume loss of the SL-C/C are about 0.02-0.05 and 0.2 mm^3, lower than those under the same load. The COFs of most RL-C/C and SL-C/C specimens remain stable or decrease slightly with time, while those of the graphite and pyrocarbon specimens increase. The thickness of the integrated friction film of the RL-C/C decreases with load, but the wear surface of the SL-C/C is rough. Tough the wear surface of the graphite is integrated, the serious abrasive wear make the debris move easily and accumulate on the edge of the wear trace to form a restacked morphology. On the wear surface of the pyrocarbon material, some loosed debris, circular worn holes and flake worn out pyrocarbon has been found.

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。

This indicated that under certain conditions it would get saturation in sublingual absorption of insulin.

当它与舌下粘膜的作用仅为30分钟时，就会在粘膜表面形成很多排列整齐的小孔，膜表面的粗糙度RMS也发生了显著下降；不同来源的粘膜在结构上存在差异。

In the fixation of a tendon to bone the apposing surfaces of both bone and tendon should be scarified to hasten attachment. Thus the periosteum must be incised and eleated enough to expose the bony surface and permit scarification.

在肌腱与骨固定时，为加快二者的愈合，应在肌腱与骨的接触面造出粗糙面，骨膜必须切开、剥离以暴露足够的骨表面，便于搔刮去除表面皮质。

Finally, the experimental setup of MR intelligent boring bar was built on the CA6140 type lathe. The experimental results show that the method can suppress the chatter efficiently and can improve the surface quality of workpieces significantly, whose roughness has decreased from 10 μm to 1.5 μm.

The electroformed copings and interfacial area were examined by SEM and EDS analysis. Results: Surface roughness increased by sandblasting, O content had not been greatly improved by preoxidation, the coping surface formed a porous structure after applying gold bonder.

结果：喷砂可以增加金沉积表面的粗糙度，预氧化没有使氧元素含量得到很大提高，涂布金黏结剂后金沉积表面形成了多孔样的结构：金瓷结合紧密，可见明显的机械嵌合结构，金瓷界面出现了铝、氧元素的单纯扩散。

Further quantitative measurement demonstrates that the irregularity of the spalled surface can be characterized with fractal dimension. Moreover, the scaling range of similar pattern and the fractal character can be correlated to microstructral size distribution and damage process in some way.

对层裂剖面的定量测量结果表明，层裂表面具有分形特征，可以用分维很好地表征层裂表面的粗糙程度及不规则性，且其标度范围与材料的微结构尺寸分布及层裂损伤演化过程有一定的关系。

分析结果表明，纤维的表面比较光滑并存在一些小而规整的小突起时，涂层的分布是均匀的，这些小突起有利于增大纤维的表面积，提高纤维表面的粗糙程度，从而增强纤维与树脂之间的结合性能。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。
