| 摘 要： | 用非线性误差方程直接平差的方法，运用非线性规划中的算法，将非线性误差方程直接平差归结到非线性规划中无约束优化范畴。算法中采用使目标函数值下降的搜索方法，避免了将误差方程线性化造成的精度损失和求解法方程过程中的凑整误差造成的误差影响。

| Abstract: | By means of the computing method of nonlinear programming,the problem of direct adjustment of nonlinear error equation can be summed up into the category of unconstrained optimization of nonlinear programming. By adopting a computing method which can decrease the object function value,both the loss of precision due to linearization of error equation and the effect of the error due to the rounding-off in solving the normal equations can be avoided. |
