Based on the analysis to Fourier, Wavelet and Hilbert-Huang Transform, the application of Hilbert-Huang Transform in the analysis of strong earthquake records is discussed with 60 strong aftershocks in Jiji earthquake series.

• 摘要在简要地介绍比较了傅立叶变换、小波变换、希尔伯特－黄变换理论的基础上，针对集集地震大量强震记录进行各种变换分析比较，以探求希尔伯特－黄变换在强震记录分析中应用的前景。
