【Abstract】 Source, order of magnitude, and predominant, period of the noise of digital seismograph network in the western Yunnan has been discussed in this paper. The lower limit of seismo-measurement ability determined by noise level has been given here and the influence of noise on arrival time and spectra has been also estimated.更多还原
