The Mo center of [Mo8](superscript 4)-shows a slight distorted square antiprism coordination environment. The N atoms of cyano groups, acting as acceptors of hydrogen bonds, together with protonate N atoms from organocations and the lattice water, serving as donors of hydrogen bonds, form intricate hydrogen bond interactions, thus generating three-dimensional supramolecular network with the help of π-π interactions of some organocations.
Mo8(上标 4-)离子中,Mo中心处于扭曲的反四棱柱配位环境。8个未配位的氰基氮原子作为氢键的受体,有机阳离子上质子化的氮原子和结晶水作为氢键的给体,形成了丰富的氢键作用,这些氢键作用连同部分有机阳离子间的π-π堆积、阴阳离子间的静电力和Van Der Waals力构筑成三维超分子网络。

The foundation of arch dam usually is layer rock base, and the depths of the layer are small, it is common that several layer rock base contact with one layer element grid. According to the geometry relation and the property of shape function, a new element kind that includes 24 nodes has been proposed to dissect the dam and foundation effectively, whose shape function are independent. In fact the element can be looked as a hexahedron divided into five small hexahedrons. It can be simulate all kind of the condition of the base and the dam.
拱坝的地基一般是层状岩石地基,有的层厚度很小,这样就有多个岩层和坝体某层单元接触,本文根据岩基与坝体接触的几何关系,利用形函数的性质,提出24节点六面体层单元,这种单元实际上是将一个厚的六面体单元分成5个更薄的六面体单元而形成的,其形函数采用可以拆分的形式表达,因此可以方便地解决坝体单元的一、二、三、四个面与错动带接触的情况,可以模拟一、二、三、四个棱边与错动带接触的情况,还可以退化为12节点的四边形面单元,以及五面体层单元。
