中文摘要：

基于独立分量分析理论分析地球化学元素组合特征,开展非线性科学与高新信息处理技术相结合的地球化学数据处理新方法的研究。通过对日热地区水系沉积物测量资料的应用实例研究,证明了FastICA对于求取地球化学元素组合的有效性。

英文摘要：

Analyzed the association characteristics of geochemical elements using independent component analysis （ICA）. The new concept of combining nonlinear science with information technology in geochemical data processing is put forward. Through the application research of stream sediment survey material in Rire area, prove that the FastICA for the geochemical elements association calculating is effective.
