| 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、工、焦煤、瘦煤、贫煤和无烟煤煤样的镜质作了测定，共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，反映腐植煤的芳核Ｃ＝Ｃ键红外吸收波 随煤化程度增加而降低或向低波娄迁移的规律。有理由相信、腐植煤的煤化程度或牌号煤也可以用红我光谱方法精确确定。

| Abstract: | 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. |
