| 摘 要： | 本文用水下电火花微爆炸产生重复性极佳的球形冲击波,用双曝光全息干涉法测量了液电冲击波的传播,并观察到冲击波与水下电极之间的相互作用.实验结果表明此法适用于液电冲击波的测量,特别适用于由冲击波波前位移来确定其峰值压力分布.

| Abstract: | In this paper,perfectly spherical shock waves were obtained with excellent repeatability by micro-explosions of electrosparks;the propagation of the spherical shock wave was measured by using a double exposure holographic interferometer and the interaction be- tween the shock wave and the electrode was first observed.The experiments show that this method can be applied to measure the electro-hydraulic shock wave,especially,to determine the wave-front pressure distribution by wave-front displacements. |

| Keywords: | double exposure holographic interferometry electro-hydraulic shock wave fluid-solid coupling wave-front peak pressure |
