摘　　要：研究了间接分组平差中两组平差和多组平差的推算原理及方法.即先对第一组单独平差,然后再利用第一组的平差结果和第二组观测值一起平差,使得到的结果与整体平差结果一致.获得了验后单位权方差估值,平差结果的协因数阵及未知数函数的权倒数,并举例说明该方法的应用.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.
