摘要
介绍分形学理论中的非倾向性振荡分析法(DFA)分析时间序列数据的方法。应用该方法对某变形数据进行分析,分析其变形的相关性以及对后续建模分析时的作用。最后说明定标指数可以从整体上描述变形数据序列的动态变化特征。
Detrended fluctuation analysis of fraetal theory for time series are applied to study some deformation monitoring data. The correlation and effect for later model building is analyzed. Finally, it concludes that the DFA index can describe the dynamic movement character of deformation data.
