The experimental data available in literature were employed to build the incrementalratio function for relative permeability of two-phase medium.
基于已有的岩心实验数据，构造了振动采油条件下两相介质相对渗透率的变化率函数。

The results indicate that the relationship between stress ratio and strain incrementalratio in these materials is still a linear relation on the extended moblized plane.
结果表明，在扩展强度发挥面上，这几种材料的应力比与应变增量比之间仍具有线性关系。
