目前,超高压技术已能达到兆巴以上的压力范围,为研究地球深部物质及其存在状态创造了必要的条件。 在地球物理学中需要在高温高压条件下,对各种典型的岩石、矿物和金属进行密度、熔点、粘度、抗压强度、导电性、导热性、弹性系数等物理和力学性质的测定,并把这些实测数据与其它地球物理方法的观测资料相比较,从而推论地球深部的构成物质及状态,进而研究地球的动力学特征。
At present, the EHV technology has been able to reach the pressure range above megabases, creating the necessary conditions for the study of the Earth’s deep matter and its existence. In geophysics, it is necessary to measure the physical and mechanical properties such as density, melting point, viscosity, compressive strength, electrical conductivity, thermal conductivity and elastic coefficient of various typical rocks, minerals and metals under the conditions of high temperature and pressure Comparing these observed data with those of other geophysical methods, we can deduce the material and state of matter in the deep part of the earth and study the dynamic characteristics of the earth.
