| 摘 要： | 将青山烟煤按不同比重分级后，分别测定了各级煤粉中痕量元素Ｂｅ、Ｃｄ、Ｐｂ、Ｃｏ，Ｃｒ，Ｃｕ，Ｎｉ，Ａｓ以及三态硫的含量，发现痕量元素与三态硫之间有一定的相关关系，本文用回归分析法建立了痕量元素与三态硫关系的模型，并用该模型对青山烟煤某一比重范围内煤粉中的痕量元素含量进行预报，结果令人满意。

| Abstract: | Qingshan bituminous powder was classified into seven parts of different specific gravity and the contents of trace elements Be, Cd, Co, Cu, Pb, Cr, Ni, As and three species of sulfur were determined. It was found that there were close relationships between the content of trace elements and three species of sulfur. A regression model of three variables was established to fit the data of trace elements and sulfates.sulfides and organic sulfur in coal and was used for prediction of trace elements. The results were satisfied. . |
