| 摘 要： | 对上海佘山钻孔形变观测资料正常的背景噪声进行初步分析并定量刻画其正常信息场的变化特征。结果显示:上海佘山形变观测资料的小波变换细节部分不同尺度包含着不同的信号成分,通过研究形变观测资料小波变换各尺度信号的非震异常特征变化,可能会捕捉到与地震孕育过程有关的前兆异常信息。

| Abstract: | We analyze characteristics of the normal background noise of borehole deformation observation data recorded at Sheshan Station in Shanghai,and quantitative characterize variation characteristics of their normal information field.The results show that the different scales of the wavelet transform detail parts of deformation observation data contain different signal components.Through studying the non-seismic anomaly characteristics change of different signal scale of wavelet transform,we may obtain precursor information of the earthquake preparation process. |
