小型超高压装置的设计原理及研究进展

Design Theory,Research and Development of Miniature Ultra-High Pressure Devices

高压研究对于寻找高压新相、制备新材料、探索地球深部奥秘具有重要的意义,但高压研究的发展却受到高压技术水平的制约。针对小型超高压装置,简要回顾了普遍使用的金刚石对顶砧(Diamond Anvil Cell,DAC)、Paris-Edinburgh Press(P-E型压力装置)的发展历史,论述了DAC、P-E型压力装置、Palm Cubic-Anvil Cell(P-CAC)、Miniature Cubic-Anvil Cell(M-CAC)等小型超高压装置的设计原理与研究进展,总结了小型高压装置存在的问题,并对其发展趋势进行了展望。

High pressure research is of great importance to the crucial information for many scientific and industrial applications,such as high pressure phase state,synthetic materials and recreating conditions deep inside the earth.Generally,the development of high pressure research is limited by the level of high pressure technology.In this paper,the history of diamond anvil cell（DAC）and Paris-Edinburgh（P-E）press were reviewed firstly.Secondly,the design theory,research,and development of miniature ultra-high pressure devices were studied in detail,including DAC,P-E press,palm cubic-anvil cell（P-CAC）,and miniature cubicanvil cell（M-CAC）.Finally,the problems and future development of the science and technologies for the miniature high pressure devices were summarized,which gives a suggestion on the new design of ultra-high pressure apparatus.
