The surface morphology, reflection rate and life time of minority carrier in multicrystalline silicon wafer were measured and analyzed.

通过扫描电子显微镜，Hitachi U-4100分光光度计和Semilab WT2000少子寿命仪分析了表面织构化后硅片的表面形貌、反射率和少子寿命。

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。

Using the changing rate of maximum feed-rate as a threshold,the surface of the part is divided into different areas according to the values of normal curvature radius.Then the feed-rate is adjusted by constant velocities of cutter contact,thus the adaptive variation of feed-rate can be reached.An example is given to prove the ra...

以最大工作进给速度的变化比率为阈值，把零件表面的法曲率半径划分为不同的区域；在不同的曲率区域内，分别以恒定的刀触点速度对进给速度进行修正，修正后的进给速度随着零件表面曲率的变化而自适应变化；实例表明该方法具有合理性和有效性。

Doping Cr into perfect TiO2 (110) surface can create the new active surface state different from that of oxygen defect surface ,AM and transition metals deposited TiO2 (110) surface. Its active surface state is the Cr 3d occupied state near EF and the value of band-gap drop from 3.13eV to 1.16eV, so photocatalysis reaction can perform in visual light area after doping Cr into perfect TiO2 (110) surface.

TiO_2(110)面掺杂Cr 可以产生不同于氧缺陷、碱金属及过渡金属负载的新表面态，其表面态为靠近E_F 的Cr3d 电子占据能带，带隙由原来的3.13ev 降至1.16eV，因此，掺Cr 后TiO_2 可在可见光区发生光催化作用。

It appears milky and is odorless until it reaches the skin surface, where it is altered by bacteria, which makes it odoriferous.

汗液在到达皮肤表面前是乳状而无味的，到皮肤表面后被细菌分解而变得有异味。

Before overcoating, the surfaces exposed in polluted environment must be thoroughly cleaned by high pressure fresh water.

如重涂前施工表面受过污染，须用高压淡水冲净表面，任其自干后，再进行重涂。

The surface treatment method of PETN by means of a surfactant is introduced.

介绍了用表面活性剂处理太安的方法，对处理后的太安进行了静电性能测试和分析，得出最佳抗静电用表面活性剂的种类及使用浓度。

The typical symptoms were that there were superficial brown lesions on pileus.

子实体被感染后，菌盖表面出现圆形或椭圆形褐色凹陷斑，在潮湿条件下，尤其是菌盖表面有水膜时，该病最容易发生。

It is studied the load-bearing surface of planet wheel axle (GCr15 Steel) by laser hardening .

对行星轮轴(GCr15钢)承载表面激光淬火后的表面强化层进行了分析研究。

The type of shock reflection over 50o wedge model is of regular reflection. The angle between the incident and reflection shock is also being increased as the model surface roughness increased. The flow visualization results indicate that the speed of reflection shock becomes slower.

在50度的模型实验条件下则会产生正规反射，当增加表面粗糙度后会使得射震波与反射震波之夹角增大，由上述两者结果可以发现，其结果可归因於反射震波之移动速度减缓所致，因此增加表面粗糙度必然会使震波反射有减弱的情况发生。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
