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。

The reflecting telescope, pioneered by Isaac Newton in the 17th century, later became the instrument of choice because of its use of mirrors, which could be constructed successfully at much great sizes than the glass lenses used in refracting telescopes.

反射望远镜是艾萨克·牛顿于17世纪首先倡导的，后来由于望远镜上反射镜的应用面成为了一种首选的设备，比起折射望远镜里使用的玻璃透镜来，它能够成功建造出尺寸大得多的望远镜。

Reflector telescope relative a larger diameter can be done, the main focus of the relative telescope diameter is about 15-125, even greater, Wang DC, inter Newton Telescope, the tube is longer than the system is much shorter focal length, coupled with the main mirror is only one apparent need for processing, which greatly reduces cost and manufacturing difficulties, there is currently greater than 134 meters diameter optical telescopes are all reflecting telescope.

反射望远镜的相对口径可以做得较大，主焦点式反射望远镜的相对口径约为15—125，甚至更大，而且除牛顿望DC远镜外，镜筒的长度比系统的焦距要短得多，加上主镜只有一个表面需要加工，这就大大降低了造价和制造的困难，因此目前口径大于134米的光学望远镜全部是反射望远镜。

To improve the pointing accuracy of the telescope mount and the capability of daylight tracking, it is necessary to do more study on the error of telescope axes. The present thesis analyses many kinds of factors that cause the pointing error of telescope mount, and discusses the method for correcting the pointing error by setting up telescope mount model in detail.

本文详细分析了望远镜机架指向产生偏差的各种因素，讨论了通过建立望远镜机架指向误差模型的方法来修正望远镜机架指向误差的方法，通过使用CCD观测恒星来求解望远镜机架指向误差模型参数。

In order to decrease the weight of tracking system and make suitable use of the Lander space, the pitching-axis of Lunar optical telescope is vertical with the Lander's flank, its rotation part is fastened on the Lander's flank, the azimuth-axis adopts rotation reflecting mirror, the flat mirror is located before the telescope tube, the angle of flat mirror and the telescope ray-axis is 45°,so that the reflecting ray can enter the telescope optical system, the scan of the mirror can be accomplished by the rotation of the telescope tube.

工作过程中望远镜支架的两个轴需带动望远镜一起转动，为了减小跟踪平台的重量和合理利用着陆器空间，又能在大范围内对太空目标进行跟踪，月基天文望远镜的俯仰轴垂直于着陆器的侧面，其转动部分固联在着陆器的侧面，方位轴采用旋转反射镜方式，将平面反射镜放在望远镜的镜筒前端，并与望远镜光轴成45°安装，使反射光线能够进入望远镜光学系统，通过转动望远镜镜筒使得反射镜实现对空间的扫描。

Accordingly, as the major targets weighing the quality of the telescope,its luminous energy concentration degree directly influence the quality of the image of the celestial body. So many kinds of technique about the optical quality testing of telescope have came forth. Hartmann screen test is one of the most classical among them and it has become one of the main testing method on several large-scale telescopes in the world because of some strongpoints suchas briefness, visuality and easy handlment.The image through the350mm telescope of the Yunnan observatory has aberration in general, subsequently,the relative position of the primary mirrior has err when blooming and reinstalling .

因此，天文望远镜光能集中度作为衡量天文望远镜质量的重要指标，直接影响到所成天体像的质量好坏，所以就出现了多种天文望远镜光学质量检测方法，其中最经典的是哈特曼光栏法，它因简单、直观、操作方便等优点而成为世界上多台大型天文望远镜的重要质量检测方法之一。

Google Sky add-on to Google Earth is developed with partnership from some of the world's leading observatories such as Sloan Digital Sky Survey, Digital Sky Survey Consortium which obtained photographic data from Oschin Schmidt Telescope on Palomar Mountain and the UK Schmidt Telescope and NASA/Space Telescope Institute, the science operations center for Hubble space telescope, the main source for Google Earth Sky add-on service where public astronomical images as well as color astronomical images of all of the archived data from Hubble's Advanced Camera for Surveys will be added and shown, together with newly released Hubble pictures will be added to the Google Sky program as soon as they are issued.

Google的天空添加就到Google Earth是发达国家与伙伴关系，从世界上一些领先的观测站，如斯隆数字天空调查，数字天空调查的财团获得摄影数据，从oschin施密特望远镜对帕洛马山区和英国施密特望远镜和美国航天局/太空望远镜研究所，科学营运中心，为哈勃太空望远镜，主要来源为Google地球天空添加对公共服务的天文图像，以及彩色的天文图像，所有的存档数据，从哈勃望远镜的高级照相机拍摄的调查加入和显示，加上新公布的哈勃照片将被加入到Google的天空计划，尽快，因为他们发出的。

Can be divided into Newtonian telescope, Cassegrain telescope, Gregorian telescope, several types of off-axis telescope.

可分为牛顿望远镜、卡塞格林望远镜、格雷果里望远镜、折轴望远镜几种类型。

Data in the gamma-ray band were acquired by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope, while the radio rotational ephemeris used to fold gamma-rays was obtained using both the Green Bank Telescope and the Lovell telescope at Jodrell Bank.

伽玛波段的数据来自于Fermi伽玛射线空间望远镜上的大面积望远镜的观测，用于折叠伽玛射线数据的射电旋转周期数据来自于Green Bank望远镜和位于Jodrell Bank的Lovell望远镜的观测。

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。
