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.
根据相关光谱线的等效宽度，推导了非等温气体辐射率的一般表达式。这些方程中可以使用任何适用于等效宽度的表达式，该表达式可以取自能带模型理论，也可以取自使用分子常数的精确计算。基于柯蒂斯 - 戈德森近似推导了辐射率的一般表达式，并将其与精确计算结果进行了比较。给出了四种不同温度分布的辐射率计算结果，以说明该方法。
