摘　　要：主要介绍了水准测量的误差来源与控制方法,提出了作者根据经验得出的i角(水准仪的视准轴在垂直方向与水准轴的夹角)的检验与校正方法,对普通水准仪和精密水准仪i角检验的区别进行阐述,同时对测量成果的中误差计算进行推理,并对中误差公式的推理过程进行阐述。This paper mainly introduces the error source and control method of leveling,puts forward the method of checking and correcting angle i obtained by the author according to his experience,distinguishes the angle i of ordinary level and precision level,deduces the calculation of mean square error of measurement results,and expounds the reasoning process of mean square error formula.
