目前超深钻探的最大深度只有13km,幔源岩石所提供的上地幔物质成分资料一般涉及的深度也仅在200km以内,全球性地球物理测量虽然能提供地球深部从地幔直至地球核心的物理参数,但无法了解地表以下各层圈的物质组成,因而开展超高压下的模拟实验研究对于了解地球深部物质的成分、性质和状态非常重要.超高压实验技术分为两大类型:动态超高压实验技术和静态超高压实验技术.动态超高压实验技术是利用各种爆轰装置产生冲击压力,同时在瞬间产生高温.在地球内部,物质一般处于静高压状态,因而动态超高压实验一般仅用来进行核幔边界区和地核物质状态方程的测定,所获得的实验结果可为静高压实验研究提供基础资料,而其他关于地球深部的模拟实验研究主要是在静态超高压实验装置中进行的.
At present, the maximum depth of ultra-deep drilling is only 13km. The mantle-derived rocks provide material depth information of the upper mantle generally only within 200km. While global geophysical measurements provide the physical parameters of deep earth from the mantle up to the core of the Earth, However, the material composition of the layers below the surface can not be known, so it is very important to study the composition, properties and state of the Earth's deep matter under the conditions of ultra-high pressure simulation experiments.High-pressure experiments are divided into two types: dynamic ultra- And static ultra-high pressure test technology.Experimental ultra-high pressure test technology is the use of a variety of detonation device to produce impact pressure, while generating high temperature in the earth.In the Earth, the material is generally in the static high pressure state, so the dynamic ultra-high pressure test is generally only used The determination of the state equations of the mantle and the mantle boundary and the state of the Earth's nuclear matter can provide the basic data for the experimental study of the hydrostatic pressure, while the other experimental studies on the deep earth are mainly conducted in the static ultrahigh-pressure experimental apparatus.
