摘　　要：利用脉冲大电流与其自身磁场相互作用产生磁压实现对样品平面等熵压缩,是国外新发展起来的动高压加载技术。CQ-4装置是在自然科学基金仪器专项资助下,建立的国内首套可实现110GPa等熵压缩,宏观金属飞片发射达15km/s的紧凑型脉冲功率装置。本文重点介绍该装置的主要性能和加载能力,以及基于其上开展的材料高压本构、相变、未反应炸药等力学行为等应用研究情况。Applying plane isentropic compression to sample is a newly developed dynamic high pressure loading technique abroad,which is achieved through the magnetic pressure produced by the interaction between pulsed high current and its self-inducing magnetic field.Based on a special financial support of instrument from National Natural Science Foundation of China,device CQ-4is the first compact pulsed power generator designed to realize magnetically driven isentropic compression up to 110 GPa and to launch macroscopic metallic flyer plate up to 15km/s in China.The main performance and loading capability of CQ-4and its application in high pressure constitutive relation,phase transition of material and mechanical behavior of un-reacted solid explosive etc.are introduced in this paper.
