Using the idea of twisted product,Lagrangian isometric immersions of a real space form into quaternion Euclidean spaces is investigated.
运用子流形理论从挠积角度研究了从实空间形式到四元欧氏空间的拉格朗日等距浸入,给出了实空间形式Mn(0)的挠积分解与相应的到四元欧氏空间的拉格朗日等距浸入之间的关系,构造了一个非平凡的适应拉格朗日等距浸入的实例。
With elastic theory of liquid crystal,we investigate bulk flexoelectric effect in a nematic liquid crystal(NLC) cell with applied voltage.

Two kinds of slope-breaks are developed in this basin, one is the syndepositional fault slope-break, the other is the syndepositional bend slope-break, whic.
根据古构造坡折带控制层序类型和层序构成模式的思路 ,通过南堡凹陷古近系同沉积构造发育特征的分析 ,认为南堡凹陷古近系存在同沉积断裂坡折带和同沉积背斜挠曲坡折带 2种类型 ,由此决定了南堡凹陷古近系主要发育了同生断裂坡折型层序和同沉积背斜挠曲坡折型层序 ,建立了这 2种类型层序体系域构成模式 。
