A small electric bulb was used as a light source, the reflector being an elliptical glass screen.

一个小电灯泡作为光源，反射器是个椭圆形的玻璃屏。

And by using IM, the RCS of a dielectric plate and array antennas of dielectric cylinders guiding electromagmetic field with finite length are calculated. IM method gets rid of the inversion of a large matrix and its solution can be fast convergent, so it is simple and especially fit for solving the problems with which the high-frequencies and the low-frequencies deal difficultly.

本文所作主要工作及贡献如下：（1）在考虑馈源匹配良好的状况下，用各种高频近似法对卡塞格伦天线、二维与三维反射面天线的电磁散射与RCS进行了全面地分析计算，并对旋转反射器表面形状进行了低RCS外形优化设计。

The facetted light-collimator merges into a facetted light-reflector (3) at a side facing away from the light source.

多面光准直器在远离光源的一侧结合于多面光反射器(3)。

At time of final inspection, all fixtures and equipment shall be clean, fully lamped, and be complete with required lenses or diffusers, reflectors, side panels, louvers, or other components necessary for the function of the fixtures.

在进行最后的检查时，所有的灯具都应该是干净的，全部安装的光源，并且配备了所有需要的透镜、散射器、反射器、面板、百叶和其他必须的功能组件。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
