摘　　要：介绍了序贯平差基本原理,当监测网秩亏时,给出了一种基于虚拟观测值权阵的计算方法,为变形监测等分期完成的测量工程提供了可取的数据处理方法;然后,分析了重心基准自由网平差、拟稳平差模型及特点,并通过实例计算比较,得出了相关结论。The basic principle of sequential adjustment of rank- deficient free network is introduced,and analyzed the process and characteristic of different methods. Provide desirable methods of data processing for deformation monitoring measurement project. Compared through experiment and get some conclusions.
