摘要
化学背景与异常在统计学上的差异同时表现在浓度和变差两个方面。在划分背景与异常时，把这两方面信息提取出来并作显化处理，使背景与异常的差别更大，以利划分，这就是Ｃ型转换的基本思想。介绍了Ｃ型转换法的基本原理及其在条件模拟和实际金矿区中的应用。
Statistically,the difference between background and anomaly is the nature of their concentration and variation. Extracting the background and the anomaly information according to geological bodies and emphasizing their difference for the convenience of their recognition is the basic principle for C-type transformation method. The concepts and the corresponding algorithm of the C-type transformation as well as its applications in conditional simulation and in ' real' gold prospecting aroa are introduced in this paper.
