摘要：

Factor analysis and cluster analysis were applied to the distribution characteristics of ten trace elements in seven Chinese coals. The factor analysis showed that a three-factor model interprets reasonably the correlations of these trace elements. The results of Q- and R-cluster analysis showed that the seven samples and ten trace elements clustered reasonably into different groups. The results can be interpreted by reference to the geochemical properties of these elements.
