高强度的

Under the vertical load, the strength of rock mass is higher when there is only one group of joint and the dip angle is less than 20 or higher than 80; When dip angle is between 20 to 80, the strength of rock mass is much lower, it is smallest when dip angle is about 50, and it is lower when this kind of dip angle is in combination with other angle.

7在铅直向荷载作用下，岩体中只存在一组倾角小于20°或者大于80°时，岩体的强度相对较高；当岩体中存在一组节理的倾角在20°～80°间时，岩体的强度值很小，而且在与其他倾角的节理组合时，岩体的的强度值变化不太大，特别是当节理倾角为50°左右的时候，岩体的强度相对最低。

The paper discusses the grain compressibility,crushability,shearing and strength characteristics of coral sand and points out that it has the characteristics of high porosity ratio,high friction angle and low strength.

特殊的物质组成、结构和发育环境导致珊瑚砂具有独特的工程性质。文章综述了珊瑚砂的压缩性、破碎性、剪切特性和强度特性，指出了其显著的土力学特点：高孔隙比、高摩擦角和低强度值。

But the latent period for reaching the platform above the water in Morris Water Maze of the Mn-exposed group was not different from that of control group. There was a significant increase in the areas,glial fibrillary acid proteinimmunoreactivity and the average proportional densities of GFAP-positive elements in nucleus caudate and accumbens in the high Mn-exposed group, and a significant reduction in the tyrosine hydroxylase immunoreactivity and average proportional densities of TH-positive elements in substantia nigra,ventral tegmentum area of midbrain and nucleus caudate in the high Mn-exposed group.

试验结果表明：该材料在高应变率扭-拉复合加载下的名义剪切屈服强度、剪切强度极限和名义拉伸屈服极限、拉伸强度极限均随温度的升高而降低。

There were three dominant species, that is Quercus liaotungensis , Corylus yunnanensis and Camphlotropis macrocarpa in the communities with artificial restoration for 9 years,16 years, and natural restoration for 16 years. These three species in these communities showed intense aggregation distribution whose intensity and area increased with the restoration time.

辽东栎、滇榛和杭子梢3个优势种群在人工恢复9年、人工恢复16年和自然恢复16年3群落内呈较强的聚集分布，聚集强度和聚集面积都随恢复时间的延长而增加，人工恢复16年群落具有较高的聚集强度，自然恢复群落具有较高的聚集面积。
