| Abstract: | This paper studies the principle and method of the two and multiple groups in the indirect adjustment.At first,the first group is adjusted. And then the adjustment result of the first group and the observation value of the second group are adjusted together. After wards,make the results agree with the overall adjustment results.the paper gets the posteriori unit weight variance value,adjustment of the results of the coordinated factor matrix and weight reciprocal of unknown function and the method of application is illustrated. |
