| 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0．1mm的孔道内，观测不到水的偏常规层流流动．

| Abstract: | 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. |
