摘要(Abstract)：

水介质中炸药的殉爆特性研究对炸药生产线设计和水下兵器设计与安全性能评价有着重要的指导意义。通过查阅国内外关于炸药殉爆及水介质中殉爆的相关研究资料，介绍了殉爆机理、殉爆影响因素、水下殉爆试验方法和水下冲击波传播特性。得出相同条件下，炸药在水中的殉爆距离比在空气中大，被发装药的殉爆可能性随着主发装药的质量增大而增大；炸药量相同，药包中心距离相同，水中爆炸时产生的冲击波峰值压力更大；在自由界面效应的作用下，冲击波的反射与透射会影响殉爆距离。
The study of the sympathetic detonation characteristic of explosives in water media has an important guiding significance for the design of explosives production lines and the design and safety performance evaluation of underwater weapons. Through the review of domestic and foreign research materials on explosive sympathetic detonation and sympathetic detonation in water media, the mechanism of sympathetic detonation, influencing factors of sympathetic detonation, underwater sympathetic detonation test methods and underwater shock wave propagation characteristics were introduced. It is concluded that under the same conditions, the gap distance in water is larger than that in air, and the probability of sympathetic detonation of acceptor cartridge increases with the increase of the mass of the main explosive charge. When the mass and distance from the center of the main explosive charge are the same, the peak pressure of the shock wave generated by the explosion in water is greater. Under the effect of free interface, the reflection and transmission of shock wave will affect the gap distance.
