摘　　要：一般的测量中,两点间的平距可以直接根据观测的斜距和高差计算,不需要进行改正。但在高精度的测量中,需要经过一系列的改正,才能得到满足精度要求的距离值。文中主要推导了归算改正的计算公式,并探讨了在实际计算过程中相关参数的取值。In the general measurement,the horizontal distance between two points could be calculated based on the observed slope distance and height difference,it needn’t to be regulated.However,in high-precision measurement,a series of corrections were required to obtain the horizontal distance that it could meet the accuracy requirements.In this paper,the calculation formula of the reduction correction was derived mainly,and the values of related parameters were discussed in the actual calculation process.
