| 摘 要： | 为研究水中爆炸气泡的脉动现象，设计了用于小当量(10 g TNT)水中爆炸研究的爆炸水箱，在爆炸水箱装置中进行了多次0.125、1.000、3.370、8.000 g TNT当量的PETN球形炸药水中爆炸试验。采用高速摄影系统获得了气泡脉动图片；给出试验范围内气泡脉动过程中气泡直径、速度及加速度随时间变化的拟合曲线。对气泡脉动直径和周期数据进行了分析，这些数据基本符合爆炸相似律。

| Abstract: | A water tank was designed to explore bubble pulses of underwater explosion.In the designed water tank,small-scale underwater explosion tests were conducted for different TNT-equivalent PETN charges of 0.125,1.000,3.370,8.000 g.After explosion of the PETN charge,bubble pulses were obtained by a high-speed camera system.Variation of the bubble diameter,expanding and contracting velocities,and expanding and contracting accelerations with time was achieved in the bubble pulse process under the given experimenta... |
