摘要
本文采用潮汐波最优谱分析法,对武山观测点断层气Rn、Hg时值资料进行了计算分析。结果表明,断层气Rn、Hg时值序列中存在着与理论固体潮相一致的半日波和日波分量,说明上述两种气体组分浓度的变化能够反映地壳岩石的应力、应变。本文的研究结果为用断层气预报地震的研究提供了一定的理论依据。
In this paper, we calculate the data of hourly values of Radon and Mercury of fault gas at Wushan by means of the optimal spectrum analysis method of tidal wave. The results show that semidiurnal and daily wave components which are consistent with the theoretical earth tide exist in hourly value sequence of Radon and Mercury content of fault gas. This proves that the change of Radon and Mercury content of fault gas can reflect the tidal stress and strain of crust. This conclusion gives the theoretical evidence of fault gas which is used in predicting earthquake.
