| 摘 要： | 运用声学基本理论，对流体中光击穿时激发声场的声压规律和指向特性进行了理论和实验研究．结果表明，当观测点与光击穿区的距离ｒ远大于柱体长度时，垂直于光传播方向的声压幅值与ｒ成反比，与光击穿长度成正比，声脉冲信号的声压幅值最大；自来水和生理盐水沿光传播方向及其夹角θ≈２９．８°时，声脉冲信号幅值最小．

| Abstract: | The force regularity and directivity of the sound field generated through the mechanism of the laser induced liquid breakdown in liquid are investigated both theoretically and experimentally according to the model.So a conclusion is drawn that the force regularity and directivity calculated by theory is in good agreement with experiment results. |
