福州乌鸦咀泉水电导率幅频谱分析初探

Amplitude frequency spectrum analysis of water electric conductance in Wuyazui fountain of Fuzhou

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,以福州乌鸦咀泉水电导率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。

Seismic observation data are influenced by diverse seasonal factors,its dynamic curve appeared as period change feature that is interact results of period or un-period factors.Using MATLAB tool box to program amplitude frequency spectrum analysis and filter wave,taking the observation data from Wuyazui fountain as a example to discuss frequency spectrum feature and earthquake exmple.
