摘    要：以复合变量为基础,提出了评定矿体变化性的两个新指标,即总体随机变化系数和局部随机变化系数,它们的大小分别反映了矿体标志总体随机性变化的大小和围绕总体趋势变化局部起伏的大小。文章最后,根据这两个指标对矿体的变化性质作了初步分类。

Abstract: In this paper,two parameters,i.e.overall random variational coefficient and local variational coefficient,in evaluating the variability of ore body are advanced based on the theory on the compound variable.The two coefficients reflect overall random variation and local random variation of ore body respectively.Simple classification of the variability of ore body is given on the basis of the two coefficients.
