摘要
结合农戈山铅锌矿铅银金属品位相关性的研究,介绍了一元线性回归分析的两个变量间相关关系的数理统计分析方法,较好地解释了铅银品位之间的数量相关关系,即铅银品位分布在拟合直线方程y=4.263736+0.733618487x±1.2范围内,银元素与方铅矿关系密切。
Combined with lead and silver grades relevancy study in Nonggeshan lead-zinc mine, introduced correlativity between two variables mathematical statistics analytical method of unitary linear regression analysis. It interpreted quantity correlativity between lead and silver grades better, that is to say lead and silver grades are distributed within fitting straight line equation： y=4.263736＋ 0.733618487x±1.2, thus there is close relation between silver element and galena.
