摘    要:本文针对非线性函数模型的平差问题,提出了非线性最小二乘平差的一种解算方法,该法与过去方法的不同在于:先将非线性函数模型按最小二乘法导出其基础方程,再对非线性的基础方程进行迭代化计算求解。

关 键 词:非线性最小二乘平差  迭代线性化  雅可比矩阵

Abstract:This papar gives a new calculating method for solvihg the problem of non-linear least squares adjustment. The difference between this method and the methods before is that in our new method the fundamental equation is obtained by the method of non-linear least squares first, then,we caculate this non-linear equation by iteration linearization.
Keywords:non-lin ear lea st squares adjustment  iteration lineari-zation  Jacobi matrix
