This result showed that effectivepressure 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。

A new index is proposed to evaluate performance of the air-powered engine-the ratio of the mean effectivepressure and the average pressure in the engine cylinder.
提出一个评价气动发动机性能的新指标——气动发动机平均有效压力和缸内平均压力的比值。

On the base of large experimental data set, the influence of effectivepressure on rock velocities is analyzed with regression method and the theory of crack closure.
