摘要
The properties of a multicomponent diffusion matrix, derived from a model for single-file diffusion, are discussed. This matrix has several pleasing characteristics, many of which can be discussed in terms of its eigenfunctions. The model has been applied to the steady-state Wicke-Kallenbach and to the transient uptake experiments. For the transient uptake, both constant pressure and variable pressure boundary conditions have been considered. Finally, the case of a first-order reversible reaction is addressed. © 1990.
