Abstract：The waveform data of the same near earthquake recorded by all the seismic station within juris-diction are studied using the Detrended Fluctuation Analysis method (DFA) .This paper explored the scal-ing exponents of the sequence before ,during ,and after an earthquake as well as three components of seis-mic waves .The value of scaling exponents can reflect the difference of signal between the seismic waves and the background noise .
Keywords：signal of near earthquakesbackground noiseDistrended Fluctuation Analysisdifference characteristic
