建立了含固相化学反应的光声模型.通过对模型的数值模拟和对不锈钢、过氨酸铵复合材料样品的光声测试验证了该模型能较好地描述由激光引发的化学反应的光声效应。

A photoacoustic model for the solid phase chemical reaction was proposed. It was verified by simulation and the photoacoustic detection of two samples of the stainless steel and an amino-perchorate composite material, indicating that the model can well describe the photoacoustic effect of the solid chemical reaction excited by laser.
