| 摘 要： | 主成分分析作为研究多变量之间关系的一种多元统计方法,巳被广泛地应用于地质学中。这是因为主成分分析不仅可以用较少的指标达到反映原多指标所提供的信息,而且可以揭示控制这些原始变量变化的某种内在因素。因此,在文献中,主成分常常被解释为物质来源、地球化学作用或成矿作用、元素赋存状态等。

| Abstract: | In this paper,the authors make an attempt to approach the theoretical possibility of the principal component analysis to apply to the division of the geuchemieal process stages and the condition of its utilization.A linear model of a set of uncorrelated geo-chemical process is C=P’X.It is proved that the geochemical process strength C is the principal component.Finally,the constraint condition applying the principal component analysis to the dividing of geochemical activity stages is suggested arid an example of application of principal component analysis is given. |
