中文摘要：
对光电测距检定中带权加常数与乘常数的最小二乘公式进行了推导，通过实例说明在基线比较法加常数、乘常数的计算中，带权观测值与不带权观测值对加常数、乘常数的评估有影响，尤其对乘常数的计算结果影响很大，因此建议检定规程中对此进行补充。
英文摘要：
The weighted least-squares formulae for additive constant and multiplicative constant in the verification of Electro-optical Distance Measurement are deduced. The results from an example show that the weighted calculation affects the estimations of additive constant and multiplication constant with baseline comparison method, specially for multiplicative constant. So it is proposed that the weighted calculations for additive constant and mulitiplicative constant should be carried out in the current verification regulation.
