| 摘 要： | 讨论在通用误差方程的基础上，已知数据用基准方程来给予体现，用秩亏平差的方式，解决独立网平差、特别是附合网平差的问题。用算例证明，基准方程平差附合网将达到传统附合网平差的目的且在某些方面优于传统平差。同时对起算数据误差的处理方式进行了探讨。

| Abstract: | This paper discusses such a problem that the known datum is reflected by the datum equation based on the general observation equations,the parameter adjustment(specially redundant known conditions) is solved using rank defect adjustment.By example,it can be demonstrated that the adjustment effect new functional model has gotten up with classical function model, and sometimes advanced it.This paper also discusse the adjustment methods that the datums contain errors. |
