简介:我们学习与一个浸透的非线性的双井潜力在一枚旋转戒指套住的基本模式。这个模型,它基于非线性的Schr?dinger方程,能以光在一根扭曲的波导管子中被构造繁殖,或在在旋转-out-of-phase的联合下面装进一个toroidal陷井的Bose爱因斯坦冷凝物(BEC),线性潜在、非线性的pseudopotential借助于旋转导致了光地和Feshbach回声。基本模式的三种类型在这个模型,对称的模型和其它被识别二不对称。在不同模式之间的模式和转变的形状和稳定性在第一个旋转Brillouin地区被调查。一个类似的模型使用了克尔媒介到造它的非线性的潜力,但是我们用浸透的非线性的媒介代替它。模型展出不仅对称碎,而且对称恢复。不稳定的不对称的模式的一种特定的类型也被发现,并且不稳定的不对称的模式的进化展示在二口线性井之间的Josephson摆动。由把模型看作一个BEC系统的一种配置,扎根的州的模式在这三种类型之中被识别,它在陷井附近描绘BEC原子的特定的分布。

简介:地下的水的overexploitation在动态水水平观察井导致地下水层次,优秀的水的变化和枯竭的连续drawdown。由于陆地沉淀,井管子高举并且观察尖系统被损坏。这些环境地质学问题能由地下水水平观察为地震异例的鉴定论述严重困难。hydrogeological理论和方法上的Basied,水平衡的关系与stressstrain条件含水土层说的纸分析和水铺平政体,然后preliminarily为在一个地下水透支区域识别水水平异例很好讨论理论和方法。我们精确地装的结果表演与上述的理论和方法和从存在数据获得的多年变化模式在联合在井区域根据drawdown漏斗的散开特性的意见判定异例的性质。研究的结果对区分在水水平上从水的长期的透支抽的单个集中的水的影响有用,正确地在地下水透支区域认出水水平异例并且增加地震分析和预言的水平。
