中文摘要:
      地质变量是一种总体变化、多级局部变化和随机变化机相叠加的综合性变量.研究表明,多级变化的这种叠加在半变异函数模型上有明显的反映(漂移效应和套合结构),即多级变化的分解与各级变化所对应之变异特征的分离应具有同步性.据此笔者指出,趋势-剩余分析或滑动平均与结构分析相结合的方法能有效地筛分地质变量中的多级变化.一个筛分断层构造的应用案例为此提供了例证.
英文摘要:
      A geological variable is a synthetic variable of the superposition of overall variation, multistage local variation and random variation. The study indicates the superposition of the variations has an obvious reflect on semivariogram models. And then, the decomposition of the variations is made synchronously with the separation of their variablities. Basing on this,the author points out the multistage variations of a variable can be sifted effectively by combining trend-residual analysis or moving average with structural analysis. Lastly, an example of sifting a fault structure with the method is given.
