反应动力学参数的优化模型及算法

干酪根降解过程中的反应动力学参数（即频率因子和活化能）是油气生成数值模 拟中必不可少的关键参数，确定这些参数的问题是个常微分方程组初值问题的反问 题。本文将该问题转化为隐式约束（即动态约束）非线性规划，并讨论规划的分解及 目标函数的性质，从而给出了可在微机上实现的优化算法和实际应用。

Optimization Model and Algorithm for Acting Dynamic Parameter

The acting dynamic parameters (frequency factor and activated energy) in Kerogen reducing process are indispensable key parameters in the numerical simulation of oil and gas generation. Problem of determining thnse parameters is an inverse problem of ordinary differential equations with initial values. This paper transforms above problems into nonlinear programming with implicit constraints (i. e. dynamic constraints), and also discusses the decomposition of this programming and the properties of the objective function, and therefore gives optimization algorithm that can be implemented on micro-computers and. practical applications.
