天文

The function of astronomical leveling in height survey of position traverse control network is introduced.

简要介绍了天文水准在阵地导线网高程测量中的作用。

The authors have discovered an important triggering factor of a violent earthquakes—the abnormal superimposition of tide-generating force resonance from typical analysis and compared all astronomical and geophysical factors.

笔者通过典型分析和普查对比各种地球物理因子和各种天文因子可能影响的整体研究，找到了大地震临震的主要触发因子——以月亮为主的非经典引潮力共振的异常叠加。

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。

It has to be parked on the building footprint itself. This meant the roof had to be comprised of a series of panels, assembled like a telescope, and stack up at one end of the stadium.

它只能是架在体育场的平面之上，这就是说，顶棚必须由一系列面板组成，像大型天文望远镜外罩那样安装，能在体育场的一端收缩之后叠在一起。

But after an audacious Shuttle repair mission, when Hubble was fixed with what is effectively a pair of eyeglasses to correct its sight, the telescope has returned some of the most stunning images ever captured by science.

但是在航天飞机大胆的解决了这个障碍以后，哈勃被安装上了有效用的镜片，纠正了它的视野范围。之后哈勃返回的图片，在天文科学史上，都是最让人感到惊奇的。

Is this the oldest telescope lens in the world?

这是最古老的天文望远镜的镜头中的世界吗？

This natural telescope is a gravitational lens.

这个天文的望远镜就是引力透镜。

Lawrence Livermore National Laboratory had him work on a similar folding problem, but this time the thing being folded was a telescope with a lens a hundred metres in diameter which had to be packed into a rocket so it could be sent into space.

劳伦斯利物摩国家实验室要他帮忙解决一个类似的&折纸&问题，这次要把一百多米粗的天文望远镜折起来放到火箭里去，好被发射到太空去干活。。。真是，行行出状元啊！呵呵

Despite all these accomplishments, it is easy to conceive that - like many amateur astronomers of today - one of his greatest loves was to turn eye and telescope upon the wonders of the night sky.

不管所有的这些成就，我们可以容易得设想，像今天的很多天文爱好者一样，他最大的爱好就是转动眼珠和望远镜于对夜晚天空的怀疑上(这句，看得懂就是翻译着别扭)。
