| 摘 要： | 利用激光驱动的等离子体实现平面准等熵压缩是近年发展起来的一种新型动高压加载方式,同时也是目前加载应变率最高的准等熵压缩方式,该技术为研究材料准等熵压缩特性和物态方程提供了一条新的途径。探索了激光驱动下平面准等熵压缩的实验技术,在100J固体激光器上成功开展了金属样品的准等熵压缩实验,利用位移干涉测速技术获取了Al/LiF样品界面的速度历史,在样品中获得了接近500m/s的原位粒子速度,应变率达106s-1,准等熵压缩峰值约7GPa.

| Abstract: | The laser-driven plasma loading is a newly developed method to realize plane, dynamic and quasi-isentropic compression of solid materials. It is also a compression mode with high strain rate. This technique provides a new way for the research on the characteristics of the materials' quasi-isentropic compression and equations of state. The compression experiments for metal materials were successfully in a 100 J solid. The interface velocity histories of the Al/LiF sample were measured with a Dopple probe system. The compression peak can reach 7 GPa with strain rate of 106 s-1. |
