This summary will be adopted for the classification of astronomical telescope introduced to enable us to understand the history of the development of astronomical telescope,status and trends.

celestial radiation ；本文将通过对天文望远镜的分类的介绍，使大家了解各种天文望远镜的发展历史，现状和发展趋势。

With the modified method, the focal field of WSRT telescope was computed. Based on the result, the dense focal plane array was designed for the telescope. The weights of focal plane array were given by the conjugate field method and the far fields of WSRT were computed.

采用改进的算法计算了WSRT望远镜的焦面场，并根据计算结果设计了WSRT望远镜的致密焦面阵结构；用共轭匹配法对阵列单元加权、计算相应的远场方向图，并与采用单个馈源时的远场方向图作比较。

In plotting scene, the invention connects fiber-optic gyro(1) with full station instrument telescope(3) by adaptor(2), and make optical fibre gyro can follow full station instrument telescope simultaneously do 180 degree turning reel full station instrument cross shaft, respectively on two horizontal positions of east and west direction of gyro axis that differ by 180 degree; each horizontal position process 2 x 2 position gyro data acquisition on full station instrument perpendicular tray that differ by 180 degree; using formula to count out full station instrument collimation axis true azimuth, survey station meridian convergence angle, then can obtain full station instrument collimation axis grid azimuth, realize full station instrument orient.

基于光纤陀螺的全站仪组合定向方法是一种应用于测绘工作的基于光纤陀螺的全站仪组合定向方法，该方法在测绘现场，把光纤陀螺(1)通过连接装置(2)与全站仪望远镜(3)固连，使光纤陀螺(1)可随全站仪望远镜(3)绕全站仪横轴(4)同步做180度转动，分别在陀螺轴东西向相差180度两个水平位置，每个水平位置在全站仪竖盘相差180度的两个竖直位置进行2×2位置陀螺数据采集；利用公式算得全站仪视准轴真方位角、测站子午线收敛角，即可进一步获得全站仪视准轴坐标方位角，实现全站仪定向。

In December 2006 France launched a space telescope called COROT that ought to be able to spot Earth-sized planets, and just this March NASA launched a much larger space telescope called Kepler .

2006年12月在法国推出了所谓的COROT天文望远镜，应该能够看清地球大小的行星，只有今年3月美国航天局发起了一个更大的太空望远镜称为开普勒。

NASA's publication of the first batch of pictures captured by Hubble Space Telescope equipped with high resolution camera earlier this year show us the collision between remote galaxies and the decadency process of stars, which outshined by dazzling gas clouds in the past were too dim for the orbiting telescope to observe.

美国宇航局NASA公布了首批由今年早些时候装配上了高分辨率照相设备的哈勃太空望远镜所捕捉到的图片。这些图片显示了遥远星系间的撞击与恒星的衰亡过程。过去，在耀眼夺目的层层气云的掩映下，它们过于暗淡，以至于这台运行在轨道上的望远镜都捕捉不到。

Using the Mayall Telescope at Kitt Peak and the DEIMOS spectrograph on the the Keck II Telescope in Hawaii, the researchers found previously unseen red giant stars out to a distance of at least 500,000 light years from Andromeda's center.

通过在Kitt Peak天文台的Mayall望远镜，以及夏威夷上Keck II望远镜上的DEIMOS摄谱仪，研究者们发现了距仙女座中心至少50万光年，从未见到过的红色巨大恒星。

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。

More direct, directer ; most direct, directest
