摘要：

The effect of chemical stresses on diffusion has been investigated. A t n plate of isotropic. material with boundary conditions of constant surface chemical potential and constant surface stresses is considered. If there is no rotation in the isotropic solid, the effective diffusivity arising from the chemical stresses is proportional to the concentration. The chemical stresses enhance the mass transfer because of increasing diffusivity. The initial surface concentration may differ from the final surface concentration for the constant surface chemical potential.
