摘要
通过对数字水准仪所具有的各项功能的理论分析,针对数字水准仪在"测量碎部点"或"中间点测量"使用方法上与光学水准仪所具有的不同特点,本文就如何提高数字水准仪"测量碎部点"或"中间点测量"的观测精度进行了探讨,供仪器使用者参考。
In this paper,the authors analyse the functions of digital level,and discuss the differences of digital and optical level in using ＂measurement of points＂ or ＂measurement of middle points＂,we focuse on how to improve the observation precision of digital level in ＂measurement of points＂ or ＂measurement of middle points ＂,and aims to provide a reference for the instrument user.
