| 摘 要： | 利用数字信号处理的相关理论与方法，对聊古1井两年的气氡逐时值数据进行适当的滤波处理，用频谱分析的方法提取潜在周期信息。结果表明：聊古I井气氡数据除明显的年周期外，还存在12小时、24小时的短周期效应和1～2个月的中长周期波动。说明数字信号处理技术对地震前兆数据处理有很好效果和应用前景。

| Abstract: | Based on digital signal processing method, the gas radon data of Liaogu-1 Well in recent two years are filtered, and its potential cycle is picked up with spectral analysis. The results show： besides the annual cycle, there are a 12 and a 24 hour short cycle and a 1--2 month moderate long cycle in the data. It indicates that digital signal processing technology is useful in the precessing of seismic precursory data. |
