Chapter 1 preface the research background and target of new generation large radio telescope are presented . the technical features and research contents of cable - suspension feed system are described 本章介绍了新一代大射电望远镜的研究背景及机电光一体化的悬索馈源系统的技术特点与主要研究内容。
It is an unavoidable fact that the radio frequencies in which radio telescopes listen for faint signals from the sky are flooded with not - at - all faint man - made radio signals that originate here on earth 这是一个无法回避的事实，射电望远镜所监听的来自太空的微弱信号淹没在地面的“强大”人造电波中。
In china , the chinese academy of sciences is supporting a new project called " pre - research on five hundred meter aperture spherical telescope fast 现时中国科学院在射电天文学这范畴中正重点支持一个名为500米口径射电望远镜预研的项目，这望远镜的英文简称为fast five hundred meter aperture spherical telescope
The works in the paper are parts of research work on the large radio telescope ( lt ) . two parts are mainly concerned here : vibration control of cabin and measurement . firstly 本文是大射电望远镜( largeradiotelescope )馈源舱支撑结构预研工作的组成部分，主要涉及馈源舱的减振与馈源舱位姿的测量两部分内容。
To participate , users have to get connected with the internet and run a free program runs like a screensaver that downloads and analyses radio telescope data as a background task 要参与该项计划，用户首先要接驳到互联网，然后启动一个免费的程式如屏幕保护程式般运行，以背景工作方式，下载和分析射电望远镜数据。

Moreover by pointing the telescope away from the din of shorter - wavelength radio waves that are used for communication on earth , astrophysicists would be able to see the early universe in unprecedented detail 此外，使射电望远镜远离地球上用于通信的短波长无线电波的喧扰，可以让天体物理学家们以前所未有的细致度观测早期宇宙。
Unlike ordinary radio telescope receivers , which point and listen to a single point in the sky at any given time , arecibo ' s new multi - beam receiver can point to seven different points simultaneously 与普通的射电望远镜接收器在一个给定的时间只能指向并监听天空中的一个点不同，阿雷西博的新多波束接收机能同时指向7个不同的方向。
The background and target of the large radio telescope fast are introduced . the study condition of cable structure is reviewed . the studied works of this dissertation are given at the end 本章介绍了大射电望远镜fast背景及技术指标；概述了柔性并联悬索机构的研究现状以及悬索式馈源支撑系统的主要研究内容；介绍了本文的主要工作和内容。
