坡度线

Indoors model test employing similarity materials and mainly considering V-class surrounding rock is carried out respectively in respect of single track and double track so that the characteristics of ground pressure, structural stress of portal and internal force distribution in various case of slope and dead-weight stress field can be investigated. The main characteristics are as follows:l.

通过室内相似材料模型试验研究，模型试验围岩参数以Ⅴ级为主，分别从单线和双线出发，详细阐述了三种新型洞门型式在正交和斜交情况下，在不同地形坡度和自重应力场作用下围岩压力和洞门结构应力及结构内力分布特征。

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。
