摘要
变异函数是 Kriging 法中的基本工具,故如何构造各向同性的变异函数是该方法中重要而关健的一个环节。原有的构造法较复杂,本文给出了两种简捷的构造新方法。
Variogram function is a elemental tool of the Kriging me- thod.How to construct isotropy variogram function is the important key link of this method.The original constructional method is compli- cated,in this paper,two new simple methods for constructing isotropy variogram are provided.
