Modeling of the Processes of Heterodiffusion in Two Ways for the Cascade Decay of Admixture Particles. І. Cascade-Type Initial-Boundary-Value Problems

We study the processes of heterodiffusion admixtures in case their cascade decay a body with two ways migration accompanied by mass exchange between states. For unbranched decay, we formulate coupled cascade-type initial-boundary-value problems which solutions problem for certain stage play role sources next stage. The are constructed using an iterative procedure help Green functions. obtain expressions diffusion fluxes migrating through given section and amounts decaying substances passing layer time.
