摘要
复杂化学反应动力学参数估值计算常具有一些特殊困难性。本文着重讨论了采用Marquardt方法估计动力学参数时遇到的一些特殊问题,其中包括:(1) 阻尼矩阵及阻尼因子对计算过程的影响;(2) Jacobi矩阵的快速计算。结合上述讨论,本文提出了快速、稳定的计算策略。
It is specially difficult to estimate kinetic parameters for the complex chemical reaction. Some particular problems are discussed in this paper which are encountered while Marquardt's method is used to estimate the parameters. These problems are: (1) The influence of damping matrix and damping factor on the calculation efficiency; (2) The fast calculation of Jacobi matrix. Based on the above discussion, fast and stable strategy is presented in this paper.
