摘要：

The unsteady transport of a reacting permeant diffusing through thin membranes and modeled red cells is investigated with a new nonlinear analysis of the reaction-diffusion equations. Implicit finite difference methods and a matrix formulation are used to study the deviation from equilibrium-based theories and the transient behavior of facilitated oxygen transport. The loading and unloading of oxygen from an erythrocyte model is computed and contrasted with the diffusion of oxygen across hemoglobin-saturated membranes.
