摘　　要：高压物理是研究高压下物质状态、结构、特性及变化规律的学科．地球本身是一个巨大的高压实验室，其内部物质无不经受高压作用．应用高田物理研究的新成就来探讨地球内部物质的相变和物性，是一项重要课题．该文从地球层田结构、地球内部物性分析入手，重点阐明高压物理与地球科学的密切联系和发展交叉学科的重大意义．：High pressure physics investrigates the state,structure,characteristics and changes of matter under high pressure. The Earth itself is a giant high pressure laboratory, since all matter in its interior is under high pressure. This article describes the application of the latest research results of high pressure physics to the study of phase transformations and characteristics of materials in the Earth's interior based on analysis of the Earth's layer struc- ture and physical characteristics of its interior. The close relationship between high pressure physics and earth sciences is stressed, as weIl as the current significance of developjng border-line science.
