摘　　要：从观测量分组的参数平差出发,详细推导了附加约束条件的序贯平差及其精度估计,讨论了附加约束条件的抗差序贯平差的计算过程。算例表明,推导的公式正确有效,简单实用,附加约束条件的序贯平差抗差估计能有效地抵制粗差的影响。The formulas of the fixed parameter sequential adjustment with constraints are conducted detailedly, and the characteristics of this method are analyzed. The robust sequential adjustment with constraints to deal with the data in which there are some outliers is also- discussed. Two examples are given to show that the formulas of the sequential adjustment with constraints among parameter are correct and effective, and that the robust sequential adjustment with constraints can effectively control the influence of the outliers.
