过去对前兆资料的分析主要基于时间域的分析，但根据有关资料介绍，也可在频率域内提取异常信息，本文将主要以抚顺地震台的数字观测资料为研究对象，从频率域内提取异常变化，方法主要从实测固体潮与理论固体潮对比分析、实测固体潮的频谱分析、功率谱估计方面进行，以完善、充实前兆资料的分析方法，提高前兆资料的分析质量。

The past analysis of the precursor data were mainly based on the time domain, but according to some relevant information, it can also be extracted from the frequency domain. Researched on Fushun seismic observation data and the anomalies extracted from the frequency domain, this paper analyzed from the aspects of the comparative analysis of the solid tide observed and the theoretical solid tide, spectrum analysis of the solid tide observed, and the power spectrum estimation. Therefore, the methods and the quality of the precursor data can be improved.
