摘要: 研究了超高速同时分幅/扫描摄影技术在炸药水中爆炸冲击波传播中的应用效果，并采用自研的同时分幅/扫描超高速光电摄影系统对炸药水中爆炸过程进行拍摄。结果表明，该系统能够拍摄同一时基、同一空基且具有超高时空分辨的一维和二维图像，进而成功观察到∅60 mm×66 mm TNT炸药在水中爆炸冲击波传播过程，获得该过程冲击波阵面平均传播速度及压力。这可为水中兵器战斗部的设计及毁伤效能评估提供参考。

Abstract: In this paper we investigated underwater-explosion shock wave propagation using the ultrahigh-speed simultaneous framing and streak photography, a system newly developed by ourselves. The results show that this system is able to record simultaneously the same spatiotemporal 1D and 2D high-resolution images of underwater explosion shock wave propagation and observe the underwater explosion shock wave propagation process of TNT with a diameter of 66mm and a length of 60 mm, and that the average propagation speed and pressure of the shock wave interface can be obtained based on the experiment, thereby providing reference for efficiency evaluation in the design of underwater weapons. -
