摘　　要：推导了附加约束条件的序贯平差抗差估计解法,对其两种解法进行了分析比较,这两种方法上是一致的。计算算例表明:附加约束条件的抗差序贯平差能有效地抵制粗差的影响。The sequential Adjustment with Constraints among Parameters is presented briefly in the first, the two arithmetics of the robustment estimation for sequential adjustment with constraints are conducted in detail, and their characteristics are analyzed. Finally, an example is given to show that the two arithmetics are correct and effective to control effectively the influence of the outliers.
