简介：本文对已经使用九十年，位于上海西郊佘山的40cm折射望远镜，利用近期拍摄的三张昴星团区域底片，在PDS上量测星象坐标，再利用天体测量标准星场：Eichhorn,H.etal的昴星团区域恒星精确位置，作为底片上星象位置的比较标准，采用作常数、三镒底片归算模型求得在底片中心周围40′×40′的象场范围内定位转换精度达0″.03，对于50′×50′和1°×1°范围，分别达0.″04和0.″05－0.″06。底片常数中相应于彗差项系数达10^－5－10^－6量级，畸变项系数达10^－8量级，这些结果表明：架望远镜的光学和装上光电导星装置的机械传动系统，仍能满足高精度的天体测量工作的要求。

简介：本文叙述了40cm望远镜的计算机控制系统的工作原理，并分硬件和软件两部分作了较详细的介绍。
