| 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。

Preliminary Discussion on the Amplitude-Frequency Spectra of Hydro-Specific Conductance of Fuzhou Wayazhi Spring |
| |
| Abstract: | The seismic observational data are affected by the periodic factors. The dynamic curve is shown in the characteristics of the periodic changes as a result of the mutual action of the periodic and non-periodic factors. The amplitude-frequency spectra and the sample are preliminarily discussed by means of MATLAB implements, compiling the procedure of analyzing the amplitude-frequency spectra and the filtering for hydro-specific conductance of Fuzhou Wayazui Spring. |
