本文提出了一种计算发光火焰和烟雾中常见的烟-气混合物的普朗克平均发射系数、吸收系数和罗斯兰平均吸收系数的简便方法。本文给出了涉及二氧化碳、水蒸气和碳烟（大多数燃烧系统中的主要物质）的混合物的具体结果。各种平均值之间的紧密一致性清楚地表明了平均吸收系数概念在应用中的有用性。
A simple procedure has been developed for the calculation of the Planck mean emission and absorption coefficients and the Rosseland mean absorption coefficient for infrared radiation of the soot-gas mixtures commonly occurring in luminous flames and smoke. Specific results are presented for mixtures involving carbon dioxide, water vapor and carbon soot, the dominant species in most combustion systems. The close agreement between the various averages clearly demonstrates the usefulness of the mean absorption coefficient concept for applications.
