摘　　要：由一维不可压流体力学理论，考虑到爆轰产物的等熵膨胀，建立了水中爆炸气泡脉动流场的基本方程。采用龙格－库塔数值方法计算了气泡脉动半径、周期及水中压力，计算结果与实测数据吻合较好。According to theory of one dimensional uncompressible flow,the basic equation on flow field of the bubble pulse by explosion under water is built up in this paper based on isentropic expansion of detonation products. The radius period of oscillation of the bubble and the water pressures are calculated numerically with Runge-Kutta method. The calculating results are unanimous with that of experiments.
