As a result, many linear methods and nonlinear methods have been developed. But the methods for processing generalized nonlinear surveying and mapping data, especially for different data types and including unknown parameters with random or nonrandom, are seldom noticed. A new algorithm model is presented in this paper for processing nonlinear dynamic multiple-period and multiple-accuracy data derived from deformation monitoring network. 展开更多

本文简述了Gauss—Newton法、改进Gauss—Newtonl法、Marquardt法和改进Marquardt法的异同,着重讨论了不重复解线性方程组的改进Marquardt法及在催化反应动力学模型非线性参数估值方面的应用。文中举出的实例为一氧化碳变换反应幂函数... 本文简述了Gauss—Newton法、改进Gauss—Newtonl法、Marquardt法和改进Marquardt法的异同,着重讨论了不重复解线性方程组的改进Marquardt法及在催化反应动力学模型非线性参数估值方面的应用。文中举出的实例为一氧化碳变换反应幂函数型动力学模型的参数估值。文中还讨论了阻尼因子的选择问题,对Fletcher选择阻尼因子方法作了适当改造。计算实践表明,不重复解线性方程组的改进Marquardt法明显优于Marduardt法,有进一步推广应用的价值。 展开更多
