本文导出了非等温气体的辐射率与谱线等效宽度的一般表达式。任何适当的等效宽度表达式都可以用在这些公式中,这些公式可以是从能带模型理论中得出的,也可以是从使用分子常数的精确计算得出的。导出了基于Curtis-Godson近似的辐射率的一般表达式,并与精确计算进行了比较。为了说明该方法,给出了四种不同温度分布的辐射率计算。
General expressions are derived for the radiance of a nonisothermal gas in terms of the equivalent width of the relevant spectral lines. Any appropriate expression for the equivalent width may be used in these equations taken either from the theory of band models or from exact calculations which use molecular constants. A general expression for the radiance is derived which is based on the Curtis-Godson approximation; this is compared with exact calculations. Radiance calculations for four different temperature distributions are given in order to illustrate the method.
