Insects make themselves at home in the most unwelcoming terrain: on steep inclines, in dark crevices, under shaky rubble.While their ability to go just about anywhere can be disturbing at times, elect...
Studies in the US have shown that black immigrants have remained at the bottom of the wage ladder and that other groups of immigrants have overtaken them over time. The goal of this research is to det...
用转换函数研究青藏高原地壳S波速度结构——"Hi-CLIMB"剖面

本文对青藏高原中部Hi-CLIMB(Himalayan-Tibetan Continental Lithosphere During Mountain Building)宽频带数字台站探测剖面资料进行处理,用转换函数模拟退火算法得到了83个台站下方S波速度结构,转化为二维速度结构剖面,并与接收函数偏移成像结果进行了对比.反演结果可清晰显示出工作区地壳内S波速度界面和不连续的莫霍面.研究表明,从N2...

CENTRAL bankers are not known for seeking solace in the heavens. But at their annual symposium in Jackson Hole, organised by the Federal Reserve Bank of Kansas City, the world’s leading monetary maven...
Soaring natural gas prices sparked higher inflation among finished, intermediate, and crude goods, resulting in the steepest increase in the finished goods index in 10 years.
青藏高原中南部Hi-Climb宽频地震探测剖面北段接收函数偏移和走时残差分析表明, 青藏高原中、西部岩石圈结构特征存在明显的不同. 青藏高原中部, 印度板块向北俯冲到羌塘地体之下, 在羌塘地体中南部达到最大的俯冲深度, 拆沉的印度岩石圈板片残留在拉萨地体中部附近之下, 深度可能超过上地幔转换带上界面; 青藏高原西部, 印度板块向北低角度俯冲, 可能俯冲到塔里木块体之下. 由于青藏高原中、西部印度板...
利用中美合作Hi-Climb项目北段吉隆-鲁谷剖面的天然地震探测数据,拾取2004~2005年期间5级以上地震事件的P波与4级以上地震的Pn波震相的走时,通过多震相层析成像反演获得青藏高原腹地的地下500 km以上的P波速度扰动结构.结果表明雅江地区为北向倾斜的低速扰动,班公-怒江断裂下方存在向南俯冲并被印度板块俯冲挤压而回折的高速体,建立了印度板块在冈底斯地块下方拆沉并被雅江低速体穿越的构造样式...
