| 摘 要： | 介绍一种在水准测量中独立闭合环或附合路线自动搜索及闭合差自动解算的新方法。该方法将间接平差函数模型转化为条件平差函数模型,利用条件方程式的所有信息,搜索出独立闭合环或附合路线并快速解算出闭合差,与给定的限差进行比较,较好地检验并剔除粗差。最后经过编程实现该方法,用实例验证了该方法的正确性和用之进行观测值质量检核的有效性。

| Abstract: | A new method is introduced,which researchs on automatic search of independent and closed loops or connecting tnaverse,and automatic calculation of closed error in leveling network.The method turns the function model of adjustment of indirect equations into the function model of adjustment of condition equations.With all information of condition equations,we can produce independent and connecting or close loops,and calculate closed error quickly.Comparing closed error with limit error,we can well inspect and delete gross error.Finally,based on program realizction,and illustrations are given to show that the algorithms are valid and effective. |
