Huang-Hilbert变换和自然时在地震电信号活动分析中的应用
Application of the Huang-Hilbert transform and natural time to the analysis of Seismic Electric Signal activities
摘要：
将Huang-Hilbert变换应用于地震电信号（SES）活动，将其分解为若干本征模函数（IMF），并研究哪种本征模函数更好地代表SES。将结果与从原始信号中减去大地电磁背景后在称为自然时间的新时域中从分析中获得的结果进行比较。结果表明，IMF的瞬时振幅可以用于区分SES从人工噪声时，结合自然时间分析。
英文摘要：
The Huang-Hilbert transform is applied to Seismic Electric Signal (SES) activities in order to decompose them into a number of Intrinsic Mode Functions (IMFs) and study which of these functions better represent the SES. The results are compared to those obtained from the analysis in a new time domain termed natural time after having subtracted the magnetotelluric background from the original signal. It is shown that the instantaneous amplitudes of the IMFs can be used for the distinction of SES from artificial noises when combined with the natural time analysis.
