反射器

Feed positioning in the way that its phase center exactly coincides with the focus of the offset parabola and its direction so that the radiation maximum falls in the geometric center of the elliptic reflector surface are not intuitive at all, as in classic parabolic antennas.

馈源用这样的方式定位——其相位中心准确位于偏馈抛物线反射器的焦点，方向也要准确，这样辐射最大值才能落在椭圆形反射面的几何中心，这样一点也不直观，正如标准的抛物面天线。

Gold 's is mainly used in gold reserve , decoration , coins and currencies . Gold can be also used as touch point of down lead and suppresser in diode and transistor .

金的主要用途：金主要做黄金储备，装饰口及货币，此外在二极管和晶体管中可作引线的触点和抑制器，还可作能量反射器。

Luneberg lens is a spherical lens which its permittivity varies with normalized radial coordinates. It is fabricated by using different homogeneous dielectric centrically layered media. The lens can focus a parallel beam of rays from any direction exactly at a point on the surface. If it is made by adding a reflecting surface "metallic cap", it is called Luneberg lens reflector. It can reflect incident wave into plane wave in incoming direction. It is usually applied in antenna, radar reflector,satellite-based, and mobile-communucation.

龙伯球透镜为一种介电系数与半径成一固定比例的球形透镜，大部分是由数层不同介电系数介电质组合而成，而其主要特性能够把入射波聚焦到球表面一点，假使在透镜表面处镀上一圆锥角金属层即为龙伯球透镜反射器，能把入射波依平面波的型态反射回原入射端，通常用於天线、雷达、卫星通讯、军事等方面。

And you can even have lots of repeaters sort of dialing into one reflector.

你甚至可以让许多种中继器拨号给一个反射器。

The objective is to use available objects such as rocket, bomb, reflectors, launchers to clear your way to the exit.

目的是要利用现有的物体，如火箭，炸弹，反射器，发射器），以明确自己的方式退出。

The secondary edge reflector is shaped and arranged with respect to the heating array and the susceptor for re-directing the misdirected thermal radiation to the outer edge of the susceptor.

二次边缘反射器相对于加热行列和衬托器而被成形并布置，可用来将误导的热辐射重新导向衬托器的外边。

Further, the reactor includes a secondary edge reflector having a specular surface positioned beside the heating array for recovering misdirected thermal radiation directed generally to a side of the heating array and away from the susceptor.

此外还包括二次边缘反射器，它有一个位在加热行列旁边的镜面可用来回收一般导向加热行列的一侧并离开衬托器的误导的热辐射。

Thus, the secondary edge reflector heats the edge and reduces thermal gradients across the susceptor and the semiconductor wafer to inhibit slip dislocations in the wafer during epitaxial layer deposition.

这样，二次边缘反射器便可加热外边并减小横越衬托器和半导体晶片的热梯度，从而可在外延生长层沉积时阻止晶片内滑移位错的发生。

All these accessories, plus a model rifle, were tagged with retroreflectors, which can reflect a beam of radiation back to its source regardless of the angle of incidence.

这些配件以及一把模型步枪上，全装著复归反射器，可以把任何角度的入射光束反射回原来的发射点。

Has been suppling bicycle accessories, such as alu water bottle, plastic water bottle, bracket, bicycle repair kit, pump, bicycle light, bicycle mirror, bicycle reflector, bicycle horn, bicycle bag, bicycle basket, reflective vest, lock glasses to Europe and America.

10年以上， Ferts开发企业有限公司已suppling自行车配件，如铝水瓶，塑料水壶，支架，自行车修理工具，泵，自行车灯，自行车镜子，自行车反射器，自行车喇叭，自行车袋，自行车的篮子里，反射背心，锁眼镜欧美。

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。
