axial cell

The concept of the maximum wetting stress level is advanced , and using this concept the phenomenon that wetting axial strain under low cell pressure is larger than that under high pressure at high wetting stress level is explained reasonably .

提出了最大湿化应力水平的概念，利用该概念合理解释了在较高湿化应力水平下低围压的湿化轴变大于高围压的的特殊现象；
