(2) 高精度三维 CT 检测技术在此类研究中极为重要，表征出贴合度较好的实验用靶是获取高质量
信号的前提。验证实验显示靶石英界面处的分层是导致冲击波卸载的主要原因。
(3) 基于本文 CH/SiO 的靶物理设计，可以实现较好的冲击波加载稳定性和干净性控制，CH 最优厚
2
度为 45～55 μm，冲击波稳定传播时长约 2 ns。
(4) 该实验技术可满足 1 000 GPa 压力范围以上高精度铜粉实验数据的获取，为高压区数据的获取
提供了一条新的技术途径。
(5) WEOS 模型结果在低压区与国外数据吻合较好，而利用本技术获得的 2 组不同初始密度铜粉实
验数据可显示出明显区分，且与独立计算的 WEOS 模型高压区结果相吻合，证明该研究技术较为可靠，
可为理论模型的外推校验提供数据支持。
