The plastic deformation induced due to cyclic rotation of principal stress axes alone can be in the same magnitude as that due to shear with fixed principal stress axes. 2 The volumetric strain due to shearing of cyclic rotation of principal stress axes is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. The former is characterized by its reversibility and is independent of past shear history, the latter by its irreversibility increases with the increase of cycle number yet its increase rate decreases with its accumulation. 3 The obvious non-coaxiality between directions of the principal stresses and principal strain increments is found and its degree depends largely on the change of shear stress component. 4 The intermediate principal stress has considerable effects on the deformation behavior of sands in the condition of cyclic rotation of principal stress axes. The accumulation rate of the irreversible dilatancy component increases with the increase of the intermediate principal stress parameter.

具有初始各向异性的砂土在纯应力主轴循环旋转排水条件下的主要变形规律为：①纯应力主轴循环旋转可产生与应力主轴固定单调剪切处于同一数量级的塑性变形；②纯应力主轴循环旋转引起的剪切体变包含可逆性剪切体变分量和不可逆性剪切体变分量两部分，其中可逆性剪切体变分量在一周内可完全恢复，基本与应力历史无关；不可逆性剪切体变分量随循环周数的增加呈单调增加，且增加速率随其自身累积值的增大呈减小趋势；③应变增量主轴与应力主轴之间的非共轴现象显著，且在一周内具有分段性；④中主应力对应力主轴循环旋转条件下砂土的变形特性有重要影响，不可逆性剪切体变分量的累积速率随中主应力系数的增加而增加。

According to More Effect,when the Hore component is placed in a gradient field,at the same time the direction of the current is perpendicular to the direction of the voltage,then between the two parallel side face come out the Hore voltage. When Hore component is set in this kind of uni-gradient magnetic field and the electric current is unchanged,the voltage output of Hore component will be proportional to the position of the Hore component in the magnetic field.

根据霍尔效应可知，置于磁场中的霍尔元件若电流方向与磁场方向垂直，则在霍尔元件垂直于磁场和电流方向的两个侧面将产生电势，将霍尔元件置于强度随空间位置线性变化的磁场中，且控制电流恒定，输出就正比于霍尔元件处于磁场中的位置，因此可以用霍尔元件来测量磁场与霍尔元件间的相对位移量。
