| 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. |
