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。

The thermally stable capability and mechanical property of the deuterated foam above were analyzed by the differential scanning calorimetry, dynamic mechanical analysis, stress-strain behavior analysis, and other methods. The results showed that the glass temperature or the decomposed temperature for the prepared foams is 100℃-120℃,or about 400℃, respectively. However, there was the irreversible change in the foams at between 50℃ and 100℃.

结果表明：1泡沫玻璃化温度在100℃-120℃，裂解温度在400℃左右；2在50℃-100℃之间和一定作用力下，泡沫存在不可逆的形变；3室温下(22℃)，随着密度增大，泡沫弹性模量增大，损耗因子减小；在泡沫密度为20 mg/cm3-160 mg/cm3时，弹性模量为2MPa-10MPa，屈服强度为0.01MPa-0.12MPa，破裂形变为5%-35%。

A TTI is a small, inexpensive device that show an easily measurable, Time-temperature dependent, irreversible change that can be correlated to quality changes of a food product that undergoes the same temperature distribution.

货架寿命指示器是一种简单便宜的质量监控装置，它能显示一种易测的与时间—温度相关的，不可逆的变化，这种变化能与经历相同温度环境的食品产品的质量相关联，从而提供所监控产品的质量变化信息和剩余货架寿命。
