入射的

Being provided by optical engine, light beam of image passes display screen of back projection to display image.

背投影显示屏幕包括一基板与位于基板的一光入射面上的一绕射光学组件层。

The deflection angle between diffraction light and incident light is a very important physical quantity.

而衍射光相对入射光的偏转角是一个很重要的物理量。

Light enters and leaves at right angles to the hypotenuse and is reflected at each of the shorter faces.

光垂直地入射和出射于棱镜的斜面，而在每一个较短的面上反射。

With it, we simulated the phase modulation and diffraction efficiency of the system, and then improved the system.

在斜入射读出光状态下，获得了大于2π的线性纯位相调制度和90％的高衍射效率。

Experimental results. show that the step number and ratio between the etching depth and the light wavelength are closely associated with the diffraction efficiency of reflection step grating.

初步试验表明，反射型阶梯光栅的衍射效率与台阶数、蚀刻深度与入射波长的比值均有密切相关。

Based on the rigorous coupled wave theory, the phenomenon that the zero order reflection efficiency of rectangular subwavelength grating varies with the wavelength is studied when incidence angle , azimuth and grating parameters are variant.

摘要从严格耦合波衍射理论出发，在不同入射角、方位角和光栅参数下的情况，计算了矩形亚波长光栅零级反射效率随入射光波长的变化。

A look into his scientific pursuit from Rutherford α-particle scattering experiment

这种弹性散射作用产生的出射粒子方向与入射方向的夹角接近180°，最初由卢瑟福作了理论分析和实验测量，故亦称卢瑟福背散射。

It is found that adatom yields, vacancy yields and sputtering yields will all increase along with the energy of incident atoms getting higher. Meanwhile, the quantities as well as distribution of adatom and vacancy play an important role in film growth.

表面吸附原子、空位缺陷以及溅射产额均随入射原子能量的增加而增加；表面吸附原子与空位缺陷的数量与分布，对于薄膜生长模式起着重要作用。

Substitute Didier Drogba equalised eight minutes from time to give Chelsea a 1-1 draw at home against Birmingham City.

后备入替的杜奥巴於完场前八分钟射入追成平手，结果车路士主场赛和伯明翰1-1。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
