框架滤波法在油气化探中的应用,突破了用一个背景值来代表数千乃至上万平方千米区域内的地球化学背景的传统,从而将非均匀的背景场刻划为一个起伏的地球化学变化面。为在低背景区发现较弱的局部异常,提供了一个新的技术思路和有效的方法。

Traditonally one background value represents the geochemical background of a region covering thousands upon thousands square kilometres,however,it has been replaced by the technique of frame filtering. In this way a heterogeneous background field is described as a rising-falling geochemical relief surface. The technique provides a new way of technology and effective method for the identification of local weak abnormals in a low background region.
