对我国煤系100多个抽提物芳烃组分样品的可见荧光特性的研究结果表明,有机质成熟过程中高度缩合芳香化合物的增加,导致荧光的“红移”,而风化、氧化作用则导致荧光的“紫移”,芳烃的可见荧光特性参数是潜在的比较理想的成熟度参数。

This paper studies the behaviour of visible fluorescence of more than 100 aromatic fraction samples extracted from various coal-series in China.The result shows that highly condensated aromatic compounds increases gradually during the maturation process of or-gantic matter,thus causing fluorescence“red shift”while the weathering and oxidization might cause fluorescence“violet shift”.The behaviour of fluorescence of aromatic hydro-carbon may be taken as fine potential index for maturation.
