简介：这份报纸处理一个模式III界面的裂缝题目到反飞机应力和在里面飞机电场。分析专注于从不一致的ferroelectric-ferroelastic领域由一个电场切换调节破裂坚韧。电的装载改变不对称的切换地区的尺寸。采用重量功能方法，我们获得韧化为的电子上依赖的开关静止并且变得界面的伪静电干扰分别地裂开。多域答案为杆得非、杆得充分的铁电体composites被导出。数字结果在批评应用压力紧张因素调节的电场上被介绍。研究提供方法由改变电场优化铁电体composites的破裂性质。

简介：为做调整的GaAs/Al0.3量井用解决时间的magneto-Kerr旋转大小被学习的Ga0.7。电子旋转松驰时间和它的在里面飞机anisotropy作为光学地注射的电子密度的功能被学习。而且，Rashba的相对力量和联合的Dresselhausspinorbit回答，并且这样观察旋转松驰时间anisotropy，被532nm的另外的刺激进一步调节连续波浪激光，经由一个光gating方法表明有效旋转松驰操作。
