摘要
提出了一种光声效应的反冲压力模型，为了证实这种模型的合理性，讨论了光声信号的大小随激光功率密度的变化关系，得出了随激光功率密度的增大，光声信号会出现一个极大值和一个极小值。
A recoil pressure model of the photoacoustic effect in solid is developed. The relation between the photoacoutic signal and the laser power density is studied to test the model. There are a maximum and a minimum of the photoacoustic signals with the increase of the laser power density.
