简介：高周波的地震变细通常被归因于有弹性的吸收。在这篇论文，我在场高周波的地震变细上的三研究并且建议物理机制源于有弹性的显微镜的多重散布波浪的干扰。首先，我在基于为波浪繁殖的基本单位是一个nano团点的概念的二阶段的媒介在波浪繁殖上建议一个新理论。由于毛孔液体和岩石框架的弹性变化，微多重散布波浪将在通过二阶段的媒介和他们的干扰的震波的波长出现，重叠将产生高周波的地震变细。第二，我在场由当模特儿的地震播送波浪的频率反应的研究与比毛孔直径没有大的厚度薄层。结果显示高周波的震波在一个近表面的水地区稍微稀释，但是在一个近表面的煤气的地区显著地腐烂。第三，我在Songliao盆用双井的射击在近表面的水和煤气的地区里分析地震变细特征，并且证明高周波的震波在水地区稍微稀释，但是在气体，宣传的1601600Hz挥动的地区显著地腐烂。来自观察与当模特儿的结果与一致的地的地震变细特征。理论上从这些研究得出的结论支持地震变细恢复。

简介：与spintronics的发展，在二维的材料的氧的行为上的调查从来没停止过。由于它的活泼的性质，氧是难的在系统独自存在。然而，它将与另外的原子交往并且生产复杂轨道的杂交效果，它影响了材料的表演。特别为在nanoscale的材料，介绍氧原子是不可避免的，不管什么在准备的过程或采用。因此，在二维的薄电影关于氧行为的效果继续研究是必要的。在这篇论文，它将主要在磁性，电的性质，阶段转变，纺纱依赖者性质和热稳定性上介绍氧行为的效果，总结影响氧行为的几个因素，并且概括在氧行为后面的机制的研究进步。
