主　　题：porosity porous layer 

摘      要：A new model consisting of a liquid film overlying a saturated and inhomogeneous porous layer is *** concentrate on effects of inhomogeneity on transition of instability *** of the averaged porosity and the gradient of porosity distribution on the instability behaviors of a liquid-porous layer system are *** average permeability of the porous layer is a key factor to determine the penetration of convection in the system.
