多岩状

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。

The subsea tunnel was constructed with the complex geological condition of connotative fault, and the crush zone and safety excavation for the zone of unfavorable geology with high external water pressure are key for the safety control of subsea tunnel.

某海底隧道地质条件异常复杂，覆岩被多处断层破碎带相割呈区域性林状分布，高外水压处断层及破碎带施工是隧道安全控制的关键所在。

Gold occurs mainly in pyrite-sericite-quartz rocks and pyrite±polymetallic-sulphides+quartz±carbonate veins and stockworks, forming veinlet-disseminated ores.

金主要产于黄铁绢英岩和黄铁矿±多金属硫化物+石英±碳酸盐脉-细网脉中，构成细脉-浸染状矿石。

Beginning with areal geologic background, the authors have discussed the features of quartz vein at Rujigou mining area Ningxia, such as lithology, contact correlation with wall rock, scales, space-time distribution, attitudes, assemblage, mineral inclusion, and have compared the quartz vein with the veins within other coalfields and coal measures.

笔者从地质背景入手，较详细的论述了汝箕沟矿区石英脉的岩性、与围岩的接触关系、规模、时空分布、产状、组合、矿物包裹体等发育特征，比较了该区石英脉与诸多煤田和煤系中脉岩的差异。

The climbing wall was different with the ones in Linz climbing club, it was the shape of wave, and was much more difficult for climbing, because it needed much more power from the arms, and much more balance from the body.

酒店里的岩壁和林茨攀岩俱乐部里的完全不同，这里的呈波浪状，攀岩难度更大，因为需要更多的臂力以及身体的平衡力。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
