| 摘 要： | 首次通过逐级化学提取试验对高级煤中10余个微量元素的赋存状态（水溶态及可交换态，碳酸盐铁锰氧化物结合态，有机质结合态，进入晶格或呈单矿物态）进行研究，结果表明：绝大多数元素具有一种以上的赋存状态；不同沉积环境条件下，元素的赋存态可以发生改变；元素的赋存状态不同，其入侵环境及对环境的危害程度不同。

| Abstract: | Study on occurrenceofAs,Cu, Pb, Zn, Co Ni, Sr, Mn, Cd, Fe in high rank coals have been carried out forthe first time through extract step by step experiments.Results have for that (1) most elements have more thanone type of occurrence; (2) begree of enterring may chamge under dirfferent sedimental environments ; (3) degree ofenterring enviroment and harm to it is different for the occurence of element is diversity. |
