Some Problems of Adjustment of A Network with Rank-Defects Discussed by Means of Orthogonal Similar Transformation Method

In this paper we find a solution of adjustment with rank-defects of a free network by means of the method of orthogonal similar transformation.This method coordinates and combines the charaeteristic of "the method of generalized inverses","the method of pseudobsevation" and "the method of auxiliary condition".Thus in demonstrating some basic theoretical problems of the adjustment,the results can be obtained simply and directely by use of the method.
