摘　　要：研究和讨论了气体滑脱的物理机制，推导了气体在多孔介质中流动包括滑脱速度在内的新方程，并且从实验得到了和理论分析一致的结果。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 veri-fy the results come from this deduction, and the experimental results obtained the same con-clusions.
