应用于地球深部物质科学研究的静态超高压实验技术

三十多年来静态超高压实验技术已发展成为实验压力、温度范围分别为1～550GPa,-256°～3500℃,主要应用于下地壳、地幔及地核物质的物理和化学性质研究,并已取得大量研究成果的一项实验技术。本文简要介绍了该项实验技术与地学领域其它高温高压实验技术的区别,以及静态超高压实验装置的两大系列——金钢石压腔装置和大腔体高压装置的特点和应用情况。并对这两大系列实验技术的发展前景和我国应有的对策进行了评述。

THE STATIC ULTRAHIGH-PRESSURE EXPERIMENT TECHNIQUE FOR EARTH INTERIOR MATERIAL RESEARCH

Static ultrahigh-pressure experiment technique has evolved over a period of about thirty years to a special experiment technique that applied in the studies on physics and chemistry of lower crust, mantle and core material, and obtained a great number of achievements. The experimental pressure and temperature range by this technique have reached 1-550GPa and -256℃-3500℃ respectively. In this paper, we present the difference between this experiment technique and other high temperature and high pressure technique of geoscience,and state the diamonal anvil apparatus and large volume apparatus-the two most major static ultrahigh pressure apparatus and their application.Firstly,the development future of this two static ultrahigh pressure experiment apparatus and application,and way to develop our cuntry's static ultrahigh pressure experiment technique are discussed.
