摘　　要：运用声学基础理论，讨论了激光能量与声信号强度间的变化关系．发现激光能量与声信号强度之间存在着对数线性关系；并根据液体中光声信号的连续性。There are optoacoustic signals produced by pulsed laser in liquid,the laser energy and the intensity of optoacoustic signals have fixed relation.The varying relation is discussed between laser energy and intensity of optoacoustic signals.Thus a method is obtained to compute the breakdown threshold in liquids.

关 键 词：光击穿 热膨胀 击穿阈值 激光能量 光声信号强度
