And 6. 9 eV can be attributed respectively to the electronic excitation of different back bond surface states, but the Peaks occurring later under ...

在低的激光能量密度下出现在2.2，3.0，4.2和6.9eV的峰表征不同背键表面态下的电激发过程，而在较高能量密度下相继出现的特征峰分别表示硅表面上的预熔、蒸发、等离子体形成等物理过程的开始。

It is proved that the upper approximation of such fuzzy rough set in a fuzzy approximation space is just its image derived according to generalized extension principle and binary fuzzy similar relation.

通过对偶方式定义了模糊集的上、下近似算子，给出了模糊粗糙集在相应的模糊关系及模糊集的截集下的表示定理，证明了这种模糊粗糙集关于模糊近似空间的上近似恰为其在二元模糊相似关系下导出的广义扩张原理之下的像。

The polyurea coating was tested with Taber tribomachine and the highp ressure water jet erosion tester for studying the wear behavior of polyure coating under conditions of dry friction and highspeed water jet contained sand. The morphology of the coating was observed with SEM and Chromatic confocal 3D Profiler. The surface component of test samp les was measured by FT2IR Spectrometer and Electron Energy Disperse Spectroscopy. The p roperties of polyurea coating under two testing conditionswas analyzed.

为研究聚脲涂层在干摩擦条件下和高速含砂水流冲蚀条件下的性能变化情况，用 Taber 磨损试验机和高速含沙水射冲蚀磨损试验机测试了聚脲涂层的磨损性能，用扫描电子显微镜和白光共焦三维轮廓仪观测涂层的磨损表面形貌，用表面红外光谱和电子显微镜能谱元素分析了涂层表面试验前后的组分变化，分析了涂层在2种摩擦条件下的磨损情况。

The third section establishes zero-coupon bond yield curve based on restraint conditions. The contents refer to data collecting and data handling, model establishing under restraint conditions and empirical analysis.

本章的第三节是在约束条件下构造中国的零息票债券收益率曲线，内容涉及到约束条件下的数据采集及处理、约束条件下的模型构造及实证分析两个方面。

The arbitrage is just an integrated and complex form of speculation trade, an advanced stage of speculation trade. The nature of the arbitragers is the same as that of the speculators. So the arbitrageurs still belongs to the speculators. The hedgers and the speculators are in a contradictive unification relation.

期货市场在不同的社会制度下具有不同的不同性质，社会主义市场经济体制下的期货市场为社会主义制度服务，资本主义制度下的期货市场为资本主义服务，它们不可避免存在斗争。

But if we are trying so simulate "blueish light from the sky", then a point that is exposed to a lot of the sky will receive more light, than a point that is behind a bunch of other objects that are blocking (i.e."occluding") the skylight.

但是实际情况下，如果我们试图模拟&天空中的微蓝色光线&，那么一个位置更加暴露在天空下的点会接受到更多的光线，而一个隐藏在一堆别的物体下的点，（也就是说&被遮挡住&的点），会完全接受不到光线。

On the bases of heating up amethyst, smoky quartz and yellow quartz; observing the change of their color; determining their absorbency and drawing the absorbency curve in different temperature and on the bases of the results of atomic absorption spectrometry, we discussed the stability of the color centers in quartz crystal.

通过在不同的温度下加热水晶，观察加热后的颜色变化，测定不同温度下的吸光度。根据各色水晶吸光度曲线特征及其在不同温度下的吸光度变化，结合原子吸收光谱分析，探讨有色水晶中空穴心的类型和稳定性。

Equivalent circuit is deduced, and then experiments on photovoltaic cell are relative...

最后对50WP多晶硅光伏电池在不同情况下的运行特性进行了实验研究，比较光伏电池在不同倾角下、不同负载及不同气温条件下对太阳能光伏发电系统发电效率的影响，实验数据确定最佳方位角和倾斜角，并分析了阴影对光伏电池的影响，数据表明当阴影遮盖面积超过50%后光伏电池输出功率降到原来的1%。

Using engineering and numerical analysis software Matlab some simulations of the model are carried out, and the motion simulations of the fish body and the caudal fin under different kinematics parameters are also carried out.

根据对鲹科加新月形尾鳍推进模式的仿生学研究，在分析游动过程中身体与尾鳍运动的基础上，建立了一维稳态游动情况下鱼体及尾鳍的运动学模型，利用Matlab工程分析与计算软件对该模型进行了运动仿真，并进行了尾鳍和鱼体在不同运动参数下的仿真研究，给出了适合仿鱼水下推进器设计的参数取值范围。

Based on the research of the Zeeman effect of 633 nm He-Ne laser, we have observed and measured the beat frequency tuning curve of 543nm He-Ne laser under different magnetic field orientations and intensities.

参照633nmHe－Ne激光器的塞曼效应，对543nm He－Ne激光器在不同方向和强度磁场下的拍频调谐特性进行了观测，发现在横向磁场作用下激光器的频差过低而且调谐曲线不规则，而纵向磁场下的调谐曲线较好，所以决定采用纵向塞曼激光器进行稳频。

And discuss some key point of integrated management system design, include hazard identification and risk assessment and risk control in the occupational health and safety management, the measure of satisfaction target of customer, the flawlessness of law system, the integration of the integrated management system and enterprise standardization system, unify lead institution and work orgnization, integreted internal audit and integrated management review.
