望远镜的

Radio telescopes are relatively inexpensive; radio signals travel at the speed of light, faster than which nothing can go; and the use of radio for communication is not a short-sighted or anthropocentric activity.

射电望远镜相对来说是昂贵的，无线电信号以光速行驶，没有什么比起它能走的更快了；而且无线电对于传播的使用不是一种短视或者以人类为宇宙中心的行为。

The lens system comprises four separated lens components, with three of them being subapertures. Two examples of apochromatic telescope are presented, both with the use of typical normal glasses, namely crown K9 and flint F5 glasses, and low-cost slightly anomalous dispersion glasses.

本文介绍了一种采用小异常色散玻璃复消色差的新型结构形式的光学系统，由四个分离的透镜组构成；给出了两个望远镜物镜设计实例，均使用价格便宜的非异常色散玻璃，校正了二级光谱、倍率色差，同时也校正了其他色差和单色像差。

It has the same simple blowback action with bolt that telescopes around the rear part of the barrel.

它具有相同的螺栓简单的反作用的行动，望远镜周围的枪管尾部。

Schmidt realized that by employing a large spherically shaped mirror (instead of the normal paraboloidal mirror of a reflector telescope) and a smaller apertured diaphragm placed at the center of curvature of the mirror, he could at a stroke eliminate coma and astigmatism.

施密特认识到雇用一个大球型镜（而不是正常的抛物面反射镜的反射望远镜）和一个较小的光阑膜片放置在中心曲率的镜子，他可以在消除中风昏迷和散光。

One of my last thoughts was of the captain, who had so often strode along the beach with his cocked hat, his sabre-cut cheek, and his old brass telescope.

最后想到的是船长，他总是沿着海滩跨着大步往前走，我想起他的三角帽，他面颊上的刀疤，还有他的旧黄铜望远镜。

By 1888 Schott improved the optical characteristics of Crown glass such that Abbe resurrected an earlier project, by 1893 he had created and patented (back dated to July 9 at the German Imperial Patent Office) a 8x 20mm "binocular telescope with increased objective separation".

待到1888年肖特改进了皇冠玻璃（BAK4）的光学性能后，阿贝才又重拾了自己早前的计划。1893年他向德意志帝国专利办公室注册了一只8x 20mm"增大物镜基线距离的双目望远镜"（专利办公室回复确认的注册日期为7月9日）专利。

Nonetheless, the instructions I used were very similar to Dobson's original Plans for Building A Sidewalk Telescope .

尽管如此，我使用的说明和多布森原始的"制作一个便携式的望远镜计划"还是很相象的。

The Doge, his advisers and the admirals of the enetian navy were taking it in roms to peer through Galileo's already improved telescope from the top of Saint Mark's Cathedral.

总督和他的顾问，以及威尼斯的海军将领们，一群人站在圣可大教堂的顶端，轮流用伽利略改良过的望远镜观看远方景物。

If you're up before dawn, look at the waning crescent moon through binoculars. The soft, pale light illuminating the moon's nighttime side is called earthshine – sunshine that is reflected from Earth and back to the moon!

如果你在黎明时抬头，通过望远镜看新月，那的柔和的、洁白的光线照亮了月球的一边，这就被称为地球反照——太阳光被地球反射到月球。

To better understand this complex and chaotic process, astronomers used the Hubble Space Telescope to image in unprecedented detail the star forming region LH 95 in the nearby Large Magellanic Cloud galaxy.

为了更好地了解这个复杂而又混乱的过程，天文学家利用哈勃太空望远镜对大麦哲伦星云附近的恒星形成区域LH95拍摄了空前详细的影像。

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。
