                                  2、中国天眼特点是什么

                                  大:反射面由4450个反射单元构成,总面积为25万平方米,相当于30个标准足球场那么大。如果把它看成是一口盛满水的锅,容量够全世界75亿人每个人分到4瓶水。

                                  巧:30吨的馈源舱通过6根钢索控制,可以在140米高空、206米的尺度范围内实时定位。

                                  强:能看见更遥远暗弱的天体,它1分钟就能发现的星体,即使把坐标提供给百米口径的射电望远镜,对方也要9分钟才能看见。

                                  精:500米的尺度上测量角度精确到8角秒,10毫米的定位精度要求最高做到了3.8毫米。
