摘要 在地球物理数据的采集的过程中,由于各种因素的影响,造成了数据的稀疏或不规则,很难直接对采集的数据进行处理解释,因此,地球物理数据的规格化就成为数据处理解释前的重要一步。本文是在前人理论的基础上,将Delaunay剖分和高斯小波函数结合起来进行地球物理数据的规格化,经过大量的理论和实际资料的处理结果显示,该方法比基于剖分的同类算法精度高,运算速度快,能够取得比较好的规格化效果,为数据资料的进一步处理提供了有力的保障。 It is rare to obtain regular data in the course of collecting geophysical data because ofdifferent kinds of natural situation, and it is also impossible to interpret them directly, so data standardization becomes important before data processing is interpreted. In this paper,the algorithm of standardizing data based on Delaunay triangulation and Guass Wavelet Function has been presented and the result is effective.
