摘要：
Flux-flow problems in slabs and cylinders, and flux-creep problems in slabs, simplified, reduce to the porous medium equation with possible sign changes. The equation's known self-similar solutions apply exactly or asymptotically if the boundary conditions are right. Flux-creep in cylinders corresponds to a modified porous medium equation that has different explicit solutions and different focusing solutions. (C) 1997 Elsevier Science B.V.
