【摘要】 本文研究了水下光击穿时所激发的声脉冲在低频段的频谱、频谱曲线在60kHz附近有一个明显的峰,给出了一个频谱的表达式,它与实验结果吻合较好。更多还原

【Abstract】 The frequency spectrum and spectrum curve at low frequency band of acoustic wave stimulated by the underwater optical puncture are des- cribed by the author.A clear peak has been found near 60kHz.An expr- ession for the frequency spectrum is shown in this paper,which is quite close to the result of the experiments.更多还原
