This result showed that effective pressure was quite obvious when the liquid was moving in low permeating and porous medium.
实验结果表明，流体在低渗透多孔介质中渗流时，受有效压力的影响明显。
2
Low permeating and porous medium was taken as an object for study, it can be educed from the experiment that the curve of permeability changed with the effective pressure.
以低渗透多孔介质为研究对象，通过实验得出渗透率随有效压力变化曲线。
3
This was because the pore space of low permeating and porous medium was very small.
