摘　　要：本文应用方差分量估计的方法,在对光电测距仪的检测成果进行数据处理时,首先求得观测值的权,然后解算仪器的加常数K,乘常数R和固定误差系数a,比例误差系数b的数值,它是用于确定同类观测不同精度观测值之间权比的一个尝试。The variance components estimation method is used to handle the data of EDMI measurements. Firstry, to find the weights of observations, then, solving for the imstrument's additive constant K, and multiplying constant R, fixed error coefficient a and proportional error coefficient b. This is an attempt to determine the wcights'ratio of the same kind observations with different accuracies.
