| Abstract: | 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. |
