位(BIT)累加技术及其应用

BIT-ACCUMULATION TECHNIQUE AND ITS APPLICATIONS

本文介绍一种用于研究多变量空间相关性和共现规律的位（ｂｉｔ）累加处理技术。主要内容为 用生成位累加图像方法计算共现指数，以定量方式表达多个变量在空间上的重叠关系。并将共现 指数转变成有确定地质意义和数量概念的变量，为地质分析和成矿有利地段的确定提供依据。

A technique of bit-accumulation processing for study of spatial correlation and co-occurrence regulurity of multi-variables is presented in this paper. The Co-occurrence Index is computed by generating bit-accumulation image for expressing the spatial superposition relationship between multiple variables quantitatively. And the Co-occurrence Indexes can be converted into new variables which have been assigned definite geologic meanings and numerical concept, providing a basis for the geological analysis and the ore-favourable area locating.
