摘要
本文在简化考虑Fermi共振的基础上。研究了CO_2分子2.7μ组合带谱带模型参数的计算方法,给出了平均吸收系数和谱线密度间隔的系统的数据。在计算中,对低温和高温两种情况分别采用不同的计算方法,为了检验数据的可靠性,使用文中所提供的数据用谱带模型理论计算了2.7μ带在某些光学路径下光谱透过率和发射率,并将它们与实验测量结果相比较,两者符合得很好。
In this paper the theorical calculations of band model parameters for combination band 2.7μ of dioxide Carbon have been investigated. Simplifying assumptions are made to account for the effects of Fermi resonance in our method. By the use of S.J, Young model, the band models for low temperatures hnve been made calculations form the line data (strength Sα and half width γα at 296K) which are given by experiment information. Under
high temperatures T≥1200K, made Correction for integrated band intensity formula, the equations are developed for computing the band model parame-ters based on the line integrated intensity and average lime spacing expressions. In addition the Statistidal band model is applied to calculate the spectral transmissivity and emissivity.
