摘要
本文叙述了电水准的采用能适应低纬子午环的高精度要求 ,分析了水平差的个别测量值产生跳变的原因 :既有其本身的结构问题 ,也有仪器其它部件的不良影响。文中还介绍了对电水准作局部改善的情况。
It is narrated that the electronic level can meet the requirements of the high precision LLMC.The reasons of anomalous jumping points including effects of the structure of the level itself and the effect from other components in the instrument are analyzed.Improvements on some parts of the level are also described in the paper.
