Based on the concept of averaging electromagnetic field, the optical constants of Goodwin synthetic ash, Chinese Qitaihe coal ash and Russian ash Br-1 were calculated by Maxwell-Garnett and Bruggeman effective medium theory. Computational results show that, for the synthetic coal slag, the optical constants estimated by EMT consist with the experimental values, but for the coal-ash produced in combustion, the optical constants estimated by EMT using industrial analytical species deviate far from the experimental values.

基于电磁场平均的概念，利用Maxwell-Garnett和Bruggeman有效介质理论分别对Goodwin人工合成灰渣、中国七台河矸石煤灰、俄罗斯褐煤灰Br-1 3组煤灰的光学常数进行计算，结果表明，人工合成灰渣光学常数的有效介质理论值与实验值吻合，而利用工业分析成分，燃烧生成煤灰光学常数的有效介质理论值与实验值有较大偏差。
