【摘要】 本文利用计算机研究了地质-地球物理区域化变量的变异特性。由于这类变量的变化具有双重性,即随机性和相关性,不可能用一般解析函数表达。利用研究区域内已有资料点的数据,可以计算出一个相应的变异函数,即实验半变异函数。该变异函数可以用来分析研究区域内各种区域化变量的变异特性。为了扩大实验半变异曲线的适用范围,可用一种理论模型进行模拟。实际应用表明,利用计算机技术,可以比常规的手工方式更迅速、更准确地求得变程a、矿块效应系数C₀及基台值C三个变异特征参数。更多还原

【Abstract】 The variation of geology-geophysical regionalized variables is studied on VAX11-780 computer. The variables are of randomness and relativity and can not be expressed by a common analytical expression. The variant function, so-called experimental semi-variant function can be established using the data of all control points in a given area. Theoretical models can be used to simulate the experimental semivariation curves and expand the applications of the curves. Among the models the spherical one is widely used in practice. Three variation parameters (range a, nugget effect C0 and sill C) can be determined much quicker and more accurately by computer than by the conventional manual way.更多还原
