| 摘 要： | 在分析顾及一阶偏导致的非线性参数平差的近似直接解法与迭代解法基础上，提出顾及到二阶偏导数的非线性参数平差的一种新的计算公式。由于非线性度量曲率立体阵的引入，使得平差计算公式表达简洁，而且便于非线性平差本质的分析。最终算例分析说明该方法的有效性及实用性。

| Abstract: | A new calculative method for nonlinear adjustment by parameters in considcration of the second-order derivates is put forward by analyzing direct solution and iteration solution to nonlinear adjustment by parameters with the first-order derivates in this paper. In the course of the derivation, the matrix is decomposed and the curative stereomatrix of the nonlinearity is drawn into so that the formulas to be deducted can be succinctly expressed and it is convenient for precise evaluation and essential analyse of nonlinear adjustment. |
