| 摘 要： | 通过水中爆炸水击波及其多次脉动的观测,分析了水击波及其多次脉动的传播速度、脉动周期、频率及能量分布等特性.观测成果表明:多次脉动在水中的传播速度与水击波的传播速度基本一致,多次脉动的能量占水击波能量的13.9%～21.7%.

| Abstract: | Through observation on shock wave and multiple pulsating caused by underwater blasting, the velocity, period, frequency and energy of shock wave and multiple pulsating are analysed. Observation findings showed that the propagation velocity of multiple pulsation under water is basically consistent with the progapation velocity of water-hammer wave, and the energy of multiple pulsation equals (13.9%)-(21.7%) of the energy of water-hammer wave. |
