摘　　要：高压分为动态(冲击)高压与静态高压,静态高压又有小压机(金刚石对顶砧,diamond anvil cell,DAC)与大压机(large volume press,LVP)产生的高压之分。材料在高压下表现出与在常温常压下完全不同的性质,通过高压研究可以系统地了解各种材料在高压下的相变和压缩行为,因此高压被广泛地应用于材料科学、地球物理学、行星科学、国防等领域。据调查,目前国外DAC能达到超过500 GPa的压力,LVP能达到125 GPa的压力,国内八面顶大压机能达到35 GPa左右的压力。通过系统总结国内外高压装置的温度、压力范围以及设计原理来揭示静高压科学的发展历程。High pressure is divided into dynamic(shock wave)high pressure and static high pressure,while static high pressure is divided into small volume press like as diamond anvil cell(DAC)and large volume press(LVP).Under high pressure,materials exhibit completely different properties under normal temperature and pressure.Through high pressure research,we can systematically understand the phase transition and compression behavior of various materials under pressure.Therefore,high pressure has been widely used in materials science,geophysics,planetary science,national defense and other fields.According to the survey,the current foreign DAC can exceed the pressure of 500 GPa,the pressure in large volume press(LVP)can reach the pressure of 125 GPa,and the domestic pressure can reach the pressure of 35 GPa.This paper systematically summarizes the temperature,pressure range and design principles of high-pressure devices at home and abroad to reveal the development history of static high-pressure science.Summarizing the temperature and pressure limits of various static high-pressure equipment at home and abroad not only allows us to have a clearer understanding of international and domestic high-pressure development trends.
