| Abstract: | This principle of dealing with two data sets in quasi-stable adjustment of free network is put forward in this paper. The atriking displacernents of moving Points are tbought as gross errors, which can be solved by iteration of robust method, and the results of quasi-stable adjustment are thus obtained. A goot effect is shown by an example. |
