摘　　要：首先根据动力学系统状态演进过程的非线性状态方程，给出了化学反应状态演变过程的有序化动力学系统模型，同时也给出了动力学系统状态空间上势函数的序参量描述形式。对化学反应过程的反应－扩散方程构造了一个基于化学反应数据特征的有序化动力学系统的序参量模型，系统在控制参数影响下，由序参量给出稳定状态的最终选择结果。所有可能的选择由势函数给出，它反应了该系统可能出现的稳定状态。最后，给出一种基于该模型的化学反应过程描述方案具有算法实现。结果表明，基于该模型的化学反应过程描述方案具有算法描述准确，计算复杂度适中等特点。According to the non linear state equation describing the state evolution of dynamic systems,an ordered dynamic model for chemical reactions has been set up,and the describing functions of the order parameters in the state space for the potential function of dynamic system are presented.Then an order parameter model of ordered dynamic system for the reaction diffusion equation based on the features of chemical reaction date has been constructed.The system can give out the final selected results of the steady state expressed by the order parameter under influences of the controlling factors.All possible selections are expressed by the potential function,it reflects the possible steady states of the system.Finally,a describibg function and an algorithm for chemical reactions based on this model are presented.The results show that the description is accurate and the complexity of computation is moderate.
