摘　　要：将高速摄影技术应用于室内水下爆炸实验研究,对爆炸容器、模型安装方法及光学测量系统进行了实验设计。通过水下爆炸实验,利用高速摄影仪观测了自由场及结构近场下气泡脉动的整个过程,获得了气泡脉动周期和最大半径,将实验数据与理论经验公式进行比较后发现,结果基本吻合。最后,对高速摄影测试技术提出改进措施。The high-speed photography （lISP） technique was applied to the investigation of indoor underwater explosion, in which the container, model installation and optical measurement system were designed. From experiments, in which detonator was located respectively below the free surface and model, the data of the radius and the period of the bubble was obtained, Compared the data with the theoretic formulations, it was consistent. Finally, how to better the high-speed photography （HSP） technique applied in studying underwater explosion was put forward.
