When NiTi alloy was tensiled at 600 ℃ and at a lower strain rate, the dynamic recrystallization occurred. Without electric field the stress-strain curves were characterized by periodical undee graph, while under the electric field they presented steady state. When deformation under the electric field, both strain hardening and recrystallization take place simultaneously, thus the flow stress curves exhibits steady state.

NiTi合金高温拉伸变形过程中会发生动态再结晶，在应变速率较低时其应力-应变曲线呈周期性波浪形，在应变速率较高时其应力-应变曲线则呈现较平滑稳定的态势；施加电场作用时抑制了这种周期波浪形变化，使应力-应变曲线呈平滑稳态变化。

The following results are got:(1) the analytical equation between the overburden pressure, the pore fluid pressure and the matrix stress is established;(2) the nonlinear relation between the porosity of saturated soils and the pore fluid pressure are obtained, which relates to the initial state and the initial pore pressure of saturated soils;(3) Based on the new principle, the rock shear strength theory and hydraulic fracturing pressure formulation are reacquired, which are much more reasonable than the traditional ones.

笔者在第一章中提出，在建立多孔介质的有效应力原理时，必须考虑其细观结构，并解析推导出了基于多孔介质之上的饱和多孔介质有效应力原理。该原理包含了孔隙度φ这一表征多孔介质结构性的重要参数；并体现了孔隙流体与固体骨架对总应力的分担作用，分担比例为φ：（1-φ）。
