摘　　要：采用理论修正方法对水下爆炸气泡脉动周期开展了研究。首先结合试验条件,采用Cole修正法、惯性修正法对水下爆炸气泡测量周期进行了计算,并同理论计算值进行了比较、分析。其次在周期计算的基础上,对气泡周期修正精度、周期系数、炸药布放深度进行分析探讨。结果表明,惯性修正法精度较高,惯性修正周期最大误差为2.35%;周期系数与炸药当量、布放深度不直接相关,炸药质量比在200多的情况下,周期系数精度误差在2%以内;最佳布放深度为一半水深下十分之一最大气泡半径处。惯性修正法用于周期计算,精度较高,满足工程要求。The pulsate periods of the underwater explosion bubble have been investigated by using theoretical revised method.First,the pulsate periods have been calculated which is based on experiment conditions by using Cole revised method and inertial revised method.The results have been analyzed and compared with theoretical calculated results.Second,based on the calculated results of the pulsate periods,those parameters have been analyzed and discussed such as the precision of the pulsate periods,the coefficient of the pulsate periods and the suspender depth of the dynamite.The results show that the inertial revised method has higher precision and the maximum error equals to 2.35%.The coefficient of the pulsate periods have no direct relationship with the dynamite mass and he suspender depth.The precision of the coefficient less than 2%even if the ratio of the dynamite mass is more than 200.The best suspender depth of the dynamite locates at one tenth of the maximum radius below half of the water depth.As to pulsate period calculation,the inertial revised method has higher precision and the results satisfied engineering requirement.
