离散反应体系的选续集总分析

LUMPING KINETICS FOR DISCRETE REACTION SYSTEM

本文讨论了多组分反应体系的动力学集总方法。该方法利用Dirac-δ函数定义描述反应体系的有关分布函数,并利用正交函数进行广义Fourier展开,从而推导出总反应速率表达式。采用这种集总方法可以使总反应速率的计算得到简化,而且可以减少对体系进行描述所需的动力学参数的数目。

A lumping method is proposed for discrete reaction system. The distribu- tion functions which are used to describe the reaction system are defined by using Dirac delta function, and approximated with generalized Fourier series. The resulting method makes the calculation of the total reaction rate much easier, and provides an effective means of reducing the number of parameters required to adequately describe the system.
