反射镜

Nowadays the light collected by the lens or mirror of a telescope is directed to a photographic plate rather than to the astronomer's eye.

被望远镜的透镜或反射镜所收集的光线，如今直接射到照相底板上，而不是天文学家的眼睛里。

The main reflector weighs approximately 125 metric tons so placing it on the alidade requires a large crane.

主反射镜的重量约125吨，所以把它列入照准需要大型起重机。

A unobstructed four-mirror anastigmat system was proposed, which was modified based on three-mirror anastigmat and had compacter structure.

介绍了一种无中心遮拦的离轴四反射镜系统，由离轴三反系统改进而成，结构更加紧凑。

The system is composed of an off-axis Three-Mirror Anastigmatic telescope and two Offner convex grating spectrometers.

该系统由离轴非球面三反射镜望远成像系统和两个Offner凸光栅光谱成像系统组成，通过改变两个光谱成像系统的变倍比来实现两种探测器的匹配。

On the situation of certain integral time, the expression of anti-scanning angular velocity of the pointing mirror was deduced.

对于积分时间一定的情况，推导出指向反射镜的反扫角速度公式。

It was found that for large aperture ratios (the ratio of focal length of the primary to its aperture, as the f-ratio in modern cameras for instance), f/10 or more, the difference between spherical and paraboloidal mirrors was negligible in the performance of the telescope.

结果发现，大口径的比例（比例焦距初级到其孔径，由于架F -比率在现代相机举例来说）， f/10或更长时间，之间的差别球面和抛物面反射镜是微不足道的，在表现望远镜。

Its fundament is to use attractive force of electrostatic field to deform membrane film whose figuration is according to imaging requirements.

由于薄膜反射镜成形过程中力场与静电场的相互耦合作用非常复杂，使其到目前为止在面形控制的理论分析上仍未有定量的结果。

In the antenna system, a dual-reflector antenna with two paraboloids is fed by the beam waveguide feeding system formed by three reflectors, realizing quick scanning of the beam.

该天线利用由三面反射镜组成的波束波导对一个由两个抛物面镜组成的双反射面天线进行馈电，实现了波束的快速扫描。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
