The main reason is affected by ground-based measurements of atmospheric refraction, atmospheric absorption and scattering, atmospheric gravity jitter as well as the telescope tube bending occurs under a variety of factors, such as observation accuracy and difficult to improve the observed star.

主要原因是地面测量受大气折射、大气吸收和散射、大气抖动以及望远镜在重力作用下出现的镜筒弯曲等多种因素制约，观测精度和观测星等难于提高。

Its span 12.8 meters, the telescope tube diameter 4.27 meters, the weight 11 tons, by three major part are composed, the first part is the opticator, the second part is the scientific instrument, the third part is the servosystem, including two lengths 11.8 meters, the width 2.3 meters, can provide 2.4 kilowatts powers the solar cell windsurfboards, two the parabolic antenna which use with the ground communication.

它全长12.8米，镜筒直径4.27米，重11吨，由三大部分组成，第一部分是光学部分，第二部分是科学仪器，第三部分是辅助系统，包括两个长11.8米，宽2.3米，能提供2.4千瓦功率的太阳电池帆板，两个与地面通讯用的抛物面天线。

The telescope tube front part is the opticator, behind is a ring-like cabin, inside this cabin, in the telescope host mirror focal-plane is placing group of scientific instruments; The solar cell windsurfboard and the antenna middle partially stretch out from the tube.

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。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
