摘　　要：介绍了一种简单的勘查地球化学数据调整方法———归一化,该方法采用各批或各区块差异数据的平均值或中位数的衬值乘以参照值以获得元素的视含量,用于调整不同分析批次之间的系统误差,或不同背景区数据的差异;用2个实例详细介绍了该方法的应用效果。In this paper, a simple method for normalization of geochemical data is described. It can be used to reduce the differences between different analytical batches and normalize the data from different areas which have different background values. The method lies in using the ratio of the original analytical value to mean or median value in the batch multiplied by a reference value. The transfer value is given the name apparent content. Two examples are given in this paper to illustrate the details of adjusting the differences.
