摘要
本文分析了国外用于测定度盘分划改正的几种方法，并分析了固定角距法的优点和不足之处；详细叙述了组合固定角距法测定对径改正的原理和计算公式；并且讨论了两对显微镜之间夹角变化以及显微镜比例尺变化对对径改正的影响，给出了相应的修正方法。用固定角距法所测的对径改正精度可达±０″．００９。
The previous methods to determine the graduation-error are introdueed and analysed in this paper. The superiority and the shortcoming of the fixed angular distancemethod are also discussed. A new method named as the combination of the fixed angular distances is proposed. The precision of the graduation-error by using this method is about±0.009 arcsecond.
