查询词典 shear modulus

We found that in the case of neglecting magnetic shear, the plasma current also can be driven by the shear Alfvén wave and the circularly polarized wave, respectively, the efficiency of current drive in the rotation plasma is independent of the plasma density In addition, it is found that whether m=0 or m≠ 0, the effect of the magnetic shear on the compressional Alfvén wave current drive makes the efficiency be dependent on the plasma density and inversely proportional to it.

当考虑旋转效应而不考虑磁剪切效应时，等离子体平板模型下平面极化压缩阿尔芬波能够驱动旋转等离子体电流，驱动效率也与等离子体密度无关，却与旋转大小成正比，这与Avinash[Phys Plasmas 4，2204（1997）]的结论一致。我们发现在这种情况下剪切阿尔芬波和圆偏振阿尔芬波都可以驱动旋转等离子体电流，旋转效应引起的电流驱动与密度无关。

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。

A plastic model was proposed which develops from the combination of boundary surface theory and multi-shear mechanism plastic theory. This model avoids the uncertainty and complication associated with the revision of Mansing's rule when a multi-shear mechanism plastic model is used, and is able to simulate the rotation of principle stress axes during seismic activities and the large shear deformation during liquefaction.

Both the scattering and rheological results indicated that the phenomenon similar to"double cloud point", which has been found along the vorticity direction by previous studies, could be also observed in the velocity direction, which confirms the prediction of the above theory that the polymer blend will exhibit anisotropical complex phase diagram under shear. It's also found that the mixing along vorticity direction was reduced by weak shear but enhanced by strong shear. In addition, the more remarkable the molecular weight differences between components, the more prominent the shift of the apparent phase boundary along vorticity direction.

除了以往研究发现涡流方向存在&双浊点&现象以外在，本文的光散射和流变测试均显示，剪切场下体系在流动方向上也出现了类似&双浊点&的现象，证实了上述理论模型关于剪切场会导致二元高聚物共混体系出现各向异性的复杂表观相图（例如Miscibility Gap现象）的预测；同时发现弱剪切会导致体系涡流方向上的相容性减小，而强剪切则在该方向上增强相容性；另外，两组分分子量的差异越大，表观相界的移动越显著。
