摘要
用IR—1600系列傅利叶变换红外线分光光度计对腐植煤系列的褐煤、长焰煤、气煤、肥煤、焦煤、瘦煤、贫煤和无烟煤煤样的镜质体作了测定，其红外光谱特征反映了它们在变质程度上的区别。得出的镜质体芳核C＝C键红外吸收波数随煤级变化曲线，反映了腐植煤的芳核C＝C键红外吸收波数随煤化程度增加而降低或向低波数迁移的规律。有理由相信，腐植煤的煤化程度或牌号煤也可以用红外光谱方法精确确定。
The humilith series of lignite,long flame coal, gas coal,fat coal,coking coal,leancoal, meagre coal andanthracite are measured by FIR-1600 infrared spectrophotometer.The variation curve of infrard absorption wavenumber of aromatic-nucleus C=C bond of vitrinite with coal tands shows the shift of infrared absorption wavenumber of aromatic-nucleus C=C bond of humic coals towards lower wave number with the increase of coalification.It is believed thal the coal rand of humilith series can be determined by the infrard spectocopy method.
