望远镜地

As noted in the article "How to Choose a Telescope," telescope mounts come in two basic types: equatorial and altazimuth.

在《如何选择望远镜》一文中提到，望远镜支架有两种基本类型：赤道式和地平式。

The physical model of polarizing beam coupling and splitting system using altazimuth coude telescope is built up based on Mueller matrix and Stokes vector. The phenomena of the decreasing of the receiving efficiency are successfully explained by this model. Three dynamic phase compensation solutions are proposed: 1 Two quarter-wave plates are rotated to compensate the phase of the laser.

针对这个问题，建立了地平式折轴望远镜的共孔径偏振耦合分光模型，用Stokes矢量和Mueller矩阵分析了在望远镜旋转过程中激光偏振态的变化，数值模拟计算了望远镜处于不同方位角和天顶角时的偏振耦合分光效率，解释了实验中观察到的望远镜旋转导致偏振耦合分光效率退化的现象。

But with either telescope it was very impressive, particularly with the Cassegrain.

同样用天文望远镜，许多明亮的小星星和有明确形状的朦胧的"雾"都能清楚地的看到，特别是用卡赛格林式望远镜。

Astronomers have partially solved the problem of looking at objects near to a star's bright glare by inventing the coronagraph, which focuses all the incoming light around a dark spot in the telescope's innards, neatly clipping off most of the central starlight and passing on much of the planetary glow.

天文学家用日冕仪一定程度上解决了观测恒星强光附近物体的难题。日冕仪精巧地阻挡了进入望远镜中央区域的绝大部分恒星光，让更多的行星光进入望远镜。这样一来，日冕仪就能专注于分析望远镜内部圆形黑暗区域周围的入射光。

In the second half of the seventeenth century, therefore, the Galilean telescope was replaced for terrestrial purposes by the "terrestrial telescope," which had four convex lenses: objective, ocular, erector lens, and a field lens (which enlarged the field of view even further).

在下半年的十七世纪，因此，伽利略望远镜取代地面的目的，由"地面望远镜，"其中有四个凸镜头：目的，眼，竖镜头，和野战镜头。

Another application: a liquid crystal pane held in front of the mirror of a telescope could be used to "unwrinkle" light that has passed through Earth's turbulent atmosphere. Such adaptive optics telescopes could gain a crystal-clear view of the heavens from Earth's surface.

还有一种应用：在望远镜镜头前放一液晶片能"展平"那些穿过地球湍动大气层而"起皱"的光线，这样的主动光学望远镜能使人在地面上看见一个像水晶一样清澈的天空。

When the Martians became depressed, everyone on the planet left the cities and went to their caves for a long time. They were stuck and couldn't come out, until one day when a Martian hap pened to glimpse the beautiful Venusians through his telescope. As he quickly shared his telescope, the sight of these beautiful beings inspired the Martians, and their Depression miraculously lifted.

当 火星人沮丧时，每个人都离开城市蛰伏到他们的洞穴里，他们陷在那里无法出来，直到有天有个火星人从他的望远镜里看见了美丽的金星人，他与其他火星人分享望远镜，镜中美丽的人鼓舞了火星人，他们的沮丧不可思议地消失了。

With its thick rubber armor, its large oculars with long eye-relief (suitable for use with gas-mask) and the eye catching window of its infrared detector re-charger, the DF had become the classical example of a full fledged military binocular, the blueprint of later 7x40 clones which adopted the same design philosophy.

身披厚厚的橡胶，长出瞳距离的大目镜和用于红外观测的受光窗，DF成为了军用望远镜全能地典型，后来的7x40望远镜的蓝图基于相同的设计这里克隆了该镜。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
