摘要
针对低标(近地面)三角高程测量"两差"改正系数C在实际工程中无已知且合理的数值可以采用的问题,推证出了一种可根据实际工程的观测数据确定C值的方法,并可据此合理评定三角高程测量观测成果的精度。
Double-difference correction coefficient C without known and reasonable values can't be used in practical projects, according to the problem, this paper proposes the method of determined values C based on actual engineering data, and it can rationally assess precision for observation results of triangle leveling.
