STUDY ON SCALE DEPENDENCE OF STRAIN VALUE OBTAINED FROM CRUSTAL DEFORMATION DATA
【摘要】 从统计分析入手 ,研究了地形变资料求解地壳应变值的尺度相对性问题 .发现应变值与计算图形尺度存在显著的相关性 :随着图形单元尺度增大 ,应变值的统计平均值和均方差呈幂指数衰减的分布特征 .据此提出了利用地形变资料求解应变场时 ,进行应变值尺度归化的必要性 ,并给出了归化方法
【Abstract】 WT5BZ]Using statistic analysis,the scale dependence of crustal strain value from crustal deformation data is studied. We found that there exists obvious correlation between strain value and computational figure scale. Along with increasing of figure element scale, the statistic mean and mean square deviation of strain present power law attenuation. Based on this analysis, the necessity of strain value scale normalization is suggested for calculating strain field using crustal deformation data,and the normalization method is proposed in this paper.
