厚层性质

The parallel bamboo curtain laminated panels of different grades were manufactured in the laboratory using the mature production technology of bamboo curtain plywood, and the bending and compression properties have been studied respectively.

在不同部位竹材性质测试的基础上，分析了竹材、木材物理力学性质的差异，建立了毛竹的物理力学性质与密度之间关系的拟合方程，并针对将竹壁分成6层等厚竹篾工艺生产的竹篾，根据竹材的抗拉弹性模量分别制定了分4级、3级和2级等3种力学分级方法。

This study investigated the effect of Ni electrodepositing on the tensile properties and bending resistance of Sn-9Zn alloy.

本研究使用胺基磺酸镍浴，在一定的温及电密条件下，电镀同厚的镍层，探讨其对Sn-9Zn 合材的抗性质及在高温下抗弯曲变形能的影响。

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。

If the slope＇s rockmass is low counter-inclined or thick-interbedded with soft interlayer, its failure model is inclined to be tilting-collapsing; if the slope＇s rockmass is homogeneous and thin-bedded with hard discontinuity, its failure model is inclined to be splitting-collapsing; if the slope＇s rockmass is low sequence-inclined with densely deep tectonic joints and weathering fissures, its failure model is inclined to be sliding-collapsing.

当缓倾内层状岩质边坡的岩层较厚，岩性呈软硬互层状产出，或岩层间软弱夹层较厚时，常发生倾倒-崩落式破坏；当缓倾内层状岩质边坡的岩层较薄，且岩性较均一，或层间结构面力学性质较好时，常发生拉裂-崩落式破坏；当缓倾角层状岩质边坡岩层倾向坡外时，在陡倾构造节理和风化卸荷裂隙切割下，常发生滑移-崩落式破坏。

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。
