In about 25,000,000 year, the Changbai Mountain area experienced 4 volcanic eruption activity, the basaltic magma embarked from the upper mantle, upwelled unceasingly along the earth's crust in giant crevasse, spouted the surface by the huge energy (in geology to be called crevasse type volcanic eruption).

在大约2500万年的时间里，长白山地区经历了4次火山喷发活动，玄武岩浆从上地幔出发，沿着地壳中的巨大裂隙不断上涌，以巨大的能量喷出地表（地质学上称为裂隙式火山喷发）。

Based on the detailed study of seismic tomography image in South China, and according to the geotectonic environment and shape and heat of asthenosphere upwelling, we divided the structure of lithosphereasthenosphere at the Mesozoic upper mantle of Eastern China into three types.(1)Continental platform area (North China platform and Yangtze platform): asthenosphere upwelled along paleorift; over the plume head, the granitic rocks of crust and mantle mixed and correspondingly, Au, Cu, Mo, PbZn, etc. mineralizationconcentrated regions were formed; and at the steep contact belt of asthenosphere and the thick area of lithosphere, mediatebasic complex was formed.(2)Central area of fold zone: asthenosphere was "recumbent" at suitable depth, with adequate heat and in a great extent; by heat conduction, the interior of partial crust remelted, and the crustsource granitic rocks, and correspondingly, W, Sn and rare elements mineralizationconcentrated regions were formed.

在深入研究华南地震层析成像的基础上，按照大地构造环境和软流圈上涌形状和热度，将中国东部中生代上地幔中岩石圈软流圈构造划分为3类：(1)陆台区，软流圈沿古裂陷上涌，其柱头上方形成幔壳混熔花岗质岩及相应Au、Cu、Mo、PbZn等矿集区，并于软流圈与岩石圈厚区之陡接触带形成中基性杂岩及相应Fe矿集区；(2)褶皱带中心区，软流圈在适当深度、热量充足、较大范围内&平卧&，因热传导而致使地壳内物质部分重熔，形成壳源型花岗质岩及相应的W、Sn、稀有元素矿集区；(3)褶皱带边缘区(大兴安岭南部及华南南缘)，在软流圈上涌柱上方形成幔源或幔壳混熔的花岗质岩，相应为Cu、Au、PbZn、Mo、Ag矿集区。

The dike breach risk of the north bank is higher than the south bank in winding reaches.

本文提出黄河下游悬河决溢风险的影响因素应当包含水沙运动、区域地壳稳定性、河势演变和堤防稳定性4个方面，并据此建立了指标体系和基于GIS技术的多层次模糊综合评判模型，对不同洪水情景下黄河下游的决溢风险进行了评价。

Urine sample was digested with an acid mixture of H2SO4 and HNO3,and thallium ion in sample solution was oxidized to Tl with bromine water.

铊是剧毒稀有分散金属之一，尽管其在地壳中的含量低，但时有急慢性中毒的事件发生[1]，已被列入我国优先控制的污染物之一[2]。

A: Acceleration is the rate of change in velocity of the ground shaking (how much the velocity changes in a unit time), just as it is the rate of change in the velocity of your car when you step on the accelerator or put on the brakes.

答：地震加速度是地壳震动速度的变化率（在单位时间内速度改变量），就像你踩下油门或者刹车以后，你的汽车的速度变化率。

Meanwhile, in North America, the EarthScope project is establishing a continent-wide network of GPS locators, seismographs, and other instruments to study what's happening below the crust.

与此同时，在北美开展的&地球透镜&计划正在建立一个包括全球定位系统定位仪、地震仪和其他仪器所组成的洲际范围的网络，以研究地壳下

This paper discusses the vertical datum of single point dynamic and questions concerned of its establishment.

不同的基准所求定的高程未知参数与运动速率参数也不同，基准问题是研究地壳垂直运动的重要内容之一。

Gold came from the mantle and/or from remelted crust, while large, deep-cut faults and passageways of the remelted magmas provided possibility of transportation of the hydrothermal fluids, and brittle, brittle-ductile overlapped faults developped at the moderate-shallow levels of the mantle plumes, and related decollements, provided ideal sites for the precipitation of hydrothermai fluids.

金主要来自地幔及重熔地壳，深大断裂及重熔岩浆通道为成矿热液的迁移提供了有利条件，中浅层次的幔枝隆起及外围滑脱带中的脆性、韧—脆性叠加断裂为矿液提供了沉淀场所。

Our result shows that the best double couple solution of this Mw5.2 event is 315°,64°and 19°for strike,dip and slip angles respectively,the second nodal plane solution is 214°,74°, and 152°.The focal depth is 25±2km,suggesting that this quake occurred in the lower crust which is much deeper than most continental earthquakes.This lower crust earthquake requires that the rock should be colder than expected.We proposed generation mechanism of this deep earthquake and its implications in rock strength and thermal state.

我们以此速度结构作为模型，利用中国国家地震台网5个台站的宽频带地震数据，采用CAP方法反演2003年8月16日赤峰地震震源机制解并初步确定震源深度：再利用IRIS 9个台站远震体波数据，通过对比高频(0.7～2.0Hz)理论地震图和观测记录的方法进一步精确确定震源深度并验证反演得到的机制解，得出此次地震矩震级为5.2，震源机制解为：节面I：315°/64°/19°，节面Ⅱ：216°/74°/152°，震源深度为25±2km，已深达下地壳。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
