摘要
对钝体入水时的水下声场进行了深入研究。在水中大约 30个不同的测点上 ,测量了入水时产生的水中激波 (声波 )的压力 。
The acoustic field in water entry of blunt body was studied exten^sively.The pressures of the underwater shock wave (acoustic wave) generated by water entry were measured at about 30 different positions in water.The spatial energy distribution and the propagation velocity of the shock wave were obtained.
