| 摘 要： | 提出了固体－气体光声腔的广义热导方程，并对一维模型进行了严格的理论分析。结果表明，气体膨胀和腔的声阻抗对光声信号有明显的影响。当利用光声信号的频率特性进行定量测量时，这些影响尤为重要。

| Abstract: | Generalized thermal conductance equation for the photoacoustic gas cell is proposed. It is shown that the dilatation of the gas and acoustical resistance of the cell can influence the photoacoustic signal. |
