中文摘要：

对太原西山矿区8号煤层的肥、焦、瘦、贫等不同烟煤的镜煤组分进行了酸洗脱灰处理，并同时对这些酸洗后的样品进行了红外分峰处理和微量元素含量的测定，发现随着煤的变质程度加深，某些有机基团与某些微量元素呈正相关关系，并因其正相关系数很高而结合的可能性很大；有的呈负相关关系；也有的和微量元素部分呈正相关变化部分则呈负相关变化。因此，将煤的有机基团分为三类：微量元素亲和性有机基团、微量元素憎厌性有机基团和对微量元素既无亲和性也无憎厌性的中性有机基团。微量元素和煤的有机基团之间相互选择性很强。但无论表现为典型的亲和性还是憎厌性，其亲和、憎厌程度的变化波动趋势，均遵循一个统一的变化规律---元素周期律。典型的中性有机基团，对亲石元素和亲铁亲铜元素所表现的亲和、憎厌倾向也有明显不同，有一定的规律可循。煤中不同类型的有机基团和微量元素的正负相关性，即对微量元素的亲和和憎厌性，对元素周期律的响应型式和响应程度差别也很大。

英文摘要：

The acid pickling and demineralization for vitrain samples of fat coal, coking coal, lean coal and meager coal from 8# coal seam of Taiyuan Xishan, China was accomplished. Meanwhile, both the trace elements testing and curve fitting of infrared spectra of the samples were carried out. It shows that correlation between some of organic group and trace elements in vitrain may be positive changes, or negative changes, or they suddenly be positive or negative with the deepening of coal metamorphism. Accordingly, organic structure-groups in coal can be divided into three types： affinity organic groups for trace elements, abhorred organic groups for trace elements and the neutral organic groups which neither affinity nor abhorred for trace elements. It is discovered that the mutual selection is very intense between organic groups and trace elements in vitrain. Whether typical affinity organic groups or typical abhorred one for trace elements, their change of affinity or abhorred are all abide by a common law, namely, the element periodic law. Even if neutral ones, its tendency of affinity or abhorred for lithophile element, chalcophile and siderophile elements are obviously different.
