水准测量中尺度比参数的附加系统参数的Partial EIV模型解法

摘要

In the paper,the adjustment model of the additional systematic parameters of the scale parameter in the current level measurement is reconstructed with the partial errors-in-variables (Partial EIV) model of additional systematic parameters on the scale parameters.The calculation formula and iterative algorithm are given under the criterion of total least squares.Through practical examples and simulation data analysis,the results show that this method and the traditional method have the almost the same effect.Relevant theoretical basis is given.%针对目前水准测量中尺度比参数的附加系统参数的平差模型,本文对模型进行重构,提出尺度比参数的附加系统参数的partial errors-in-variables(Partial EIV)模型,给出总体最小二乘准则下的解算公式及迭代算法.实际算例和模拟数据结果表明,本文方法与传统方法在处理尺度比参数为附加系统参数时的效果基本一致,并给出相关的理论依据.
