摘要：

Mathematical models of homogeneous reactors often consist of stiff ordinary differential equations with initial values. A numerical algorithm, of boudary layer type, is proposed for solving these problems. A criterion is given to identify reaction mechanisms relevant to the method. Splitting the variables into stiff and non-stiff ones, and determining small perturbing parameters, are achived a priori, from mechanistic considerations. Formulae giving boundary layer lengths correspondign to various approximations are established. The paper clarifies the notion of quasi-stationay state approximation commonly used in chemical kinetics. © 1979.
