Abstract: The slip flow of gas has been deeply studied and developed.The equations which show the rate of tube flow and the seepage velocity of gas flow in porous media are derived while the effect of slip is taken into consideration,Many core samples are measured in order to verify the results come from this deduction,and the experimental results obtained the same con-clusions.

Key words: slippage porous media diffuse reflection permeability
