摘　　要：根据共振模型，讨论影响介质的吸收与色散的振子特性参数，得到关于振子阻尼系数的振子数的解析式。据此，利用介质的吸收谱曲线可以定量计算振子的阻尼系数和振子数，这对研究和改善介质的吸收和色散特性有重要意义。我们已用此方法研究气液浓度的光电特性。Vibrator character of medium was discussed according to the resonance mode, that is influence on absorption and dispersion of medium, and then analytic formula of the damping coeffcient and vibrator unmber have been derived. Accordingly to utilize the curve of absorping spectrum of the medium damping coeffcient and vibrator number of vibrator can be calculated quantitatively. That is important significance to study and improve character of absorption and dispersion of medium. We already use of that method to study photodelectric density sensing of gas and liquid.
