摘要
该文从权的定义出发，导出了先验单位权中误差的变化与平差成果的关系，发现其变化仅对验后单位权中误差、粗差探测效果和协因数阵有影响，对其它平差成果均无影响。
Starting from the definition of weight, the paper derives the relation between the change of the a priori unit weight mean error with the result of adjustment. It is found that the change has influence only on the exploring effect of the posteriori unit weight mean error, gross error and the coordinated factor matrix, but no influence on all other adjustment results.
