| 摘 要： | 目前勘探地球物理领域中应用分形与混沌理论的研究势头正方兴未艾，但对于地震记录是否具有分形与混沌特性还有存疑。本文从功率谱分析，导出了时间序列和地震记录满足分形性质的必要条件，然后通过实际地震记录的功率谱分析，证实在一定的频带范围内地震记录符合分形要求，同时也证实了地震记录的混沌性质。

| Abstract: | Research on the application of fractal and chaotic theory in exploration geophysics is just unfolding at present. However, perople still doubt whether seismic data have fractal and chaotic charcateristics. On the basis of power spectral analysis,we have derived the necessary conditions under which time series and seismic data will have fractal property. The power spectral analysis of real seismic data shows that seismic data satisfy fractal requirement within a certain frequency band,and that they also have chaotic characteristic. |
