研究了以硝基甲烷液体炸药作为冲击波发生源的准球面汇聚冲击波超高压回收装置。在该装置上,利用冲击波由金属球体表面向中心汇聚形成的高压，对样品进行了冲击处理;分析了回收的金属球体内、外破坏情况及金相组织变化。结果表明:该装置产生的球面冲击波对称性较好，样品回收可靠性较高;金属球体中心附近压力超过207 GPa;对进行超高压冲击条件下的材料回收实验有较高的实用价值。
研究瞭以硝基甲烷液體炸藥作為遲擊波髮生源的準毬麵彙聚遲擊波超高壓迴收裝置。在該裝置上,利用遲擊波由金屬毬體錶麵嚮中心彙聚形成的高壓，對樣品進行瞭遲擊處理;分析瞭迴收的金屬毬體內、外破壞情況及金相組織變化。結果錶明:該裝置產生的毬麵遲擊波對稱性較好，樣品迴收可靠性較高;金屬毬體中心附近壓力超過207 GPa;對進行超高壓遲擊條件下的材料迴收實驗有較高的實用價值。

Recover devices of samples treated under super-pressure loading by quasi-spherical converging shock wave using nitromethane liquid explosive were studied. High-pressure acting on samples were produced by shock wave front converging in metallic ball. Destruction and metallograph of metallic ball after shock treatment were studied. The results show that shock waves front is spherical Symmetry and recovery of samples is reliable. The pressure near the center of metal ball is higher than 207 GPa. The devices can be significantly used in investigating recover samples of materials loaded by ultrahigh pressure shock waves.
