摘　　要：分析了水中爆炸气泡脉动的物理规律,对其演化过程在考虑水为可压与不可压2种情况下进行了数值求解。由于假设水具有不同的状态,求解得出了气泡半径及径向速度随时间变化的规律。编写的一维ALE动力学程序计算分析了水下爆炸过程,气泡脉动计算结果与实际过程非常吻合。The paper analysed the physical law about bubbleoscillation by underwater explosion and calculated its oscillation process by taking water-compressible and water-incompressible into consideration.The results reveal different rules about bubble radius versus time and radial speed versus time because of different hypothesis in water state.One-dimension ALE dynamics program calculations of underwater explosion indicate that the calculations of bubble-oscillation satisfy the requirements the real physical process.
