The several main achievements in the research are as follow:1. Using general fractal model mothod caculate lower limit of abnormity,by contrast with traditional method,we think that received the good result.2.
取得的主要研究成果: 1.用一般分形模型算法得出的异常下限,通过和用传统方法求出的异常下限的对比,其效果明显优于传统方法。

传统上异常浓集中心是以异常下限值的1 ~ 2倍圈出的区域。
Traditionally, anomaly consistence focus is an area, which is marked out by the abnormal limit of 1 ~ 2 times.
消除这些干扰因素的最简单方法是分区统计背景值,或者用不同异常下限或用衬度值圈定异常。
The simplest way to eliminate disturbing factors is part statistics of the background values or delineating the anomalies by using the different anomaly thresholds or contrast values.
区域化探数据处理中,重点是确定地球化学异常下限,异常下限的确定是勘查地球化学的一个基本问题。
During the disposal of regional geochemical data, the key is confirmation of anomalous threshold, which is also a fundamental issue in explorative geochemistry.
