| 摘 要： | 研究了光声信号的强度与溶液浓度的关系．应用光谱学比尔定律和液体光声理论，得出了在溶液浓度不太大的条件下，光声信号强度与溶液浓度成线性关系的结论．实验结果与理论计算吻合．这对分析溶液中微量物质及通过物质浓度检测化学反应速度有一定意义

| Abstract: | The relation of the photoacoustic signal intensity and the concentration of the solution is studied. By means of Beer law in spectroscopy and the theory of photoacoustic in liquid, the linear relation between the photoacoustic intensity and the concentration of the solution is abstained. It is good agreement with the experiment result. The result is of significance in analysis the trace substance in solution and detecting the velocity of chemistries reaction. |
