摘　　要：通过推导衡量水准测量精度指标中的高差中误差的表达式,对表达式中的各参数分别加以分析,发现在仪器以及人员配备已定的前提下,减小高差中误差的唯一方法是减少水准路线的测站数,并由此提出利用平面反射的原理减少测站数的方法,从而减小高差中误差、提高测量精度。Through Derived measure leveling precision index of the error in the elevation difference of expression, the expression of the various parameters was analyzed. It was found that on the premise of instrument and personnel equipped with, the only way to re-duce the error in the elevation difference was to reduce the level line on the number of stations. And thus the authors put forward that the number of the station should decrease using the principle of plane reflection and therefore, the error will be reduced in the elevation difference, the measurement precision of the method will be improved.
