摘要
地震观测数据受各种周期性因素影响,其动态曲线表现为周期性变化特征,是大小不同的周期和非周期因素相互作用的结果。利用MATLAB工具包编程幅频分析和滤波程序,以福州乌鸦咀泉水氡的模拟观测数据为例,对其幅频谱特征和震例进行初步探讨。
Affected by periodic and nonperiodic factors, the dynamic curve of seismic observational data has quizperiodic characteristics. By using spectrum analysis and filtering program written in MATLAB, the amplitudefrequency spectra of the water radon data of Fuzhou Wayazui spring are preliminarily analyzed combined with earthquake cases.
