摘　　要：以松散颗粒介质渗透率实验出发点,考证多孔介质内流动滑移的同时,将此实验作为考察微孔道流动的方法提出,避开单一微槽道流动测量的困难。实验结果表明,大于0.1 mm的孔道内,观测不到水的偏常规层流流动。With the purpose of studying slip flow in pores,the experiment of unconsolidated sand perme- ability with water as a flow medium was carried out. The experimental method can facilitate observing statistically flow in micro-channel. The experimental result shows that abnormal laminar flow can not be observed in the pores with their average diameter greater than 0.1 mm.
