摘要
主要分析讨论了2002年1月-2005年2月银川台数字地震仪测定的震级与中国数字地震台网观测报告震级的误差，给出银川台CTS-1数字地震仪震级的校正值，以提高银川台地震速报的精度。同时初步探讨分析了银川台数字地震仪震级误差的原因。
In this paper, magnitude errors between that determined by digital seismograph record in Yinchaun Seismic Station and reported by China digital seismologic network were chiefly analyzed. Magnitude correction value of CTS-1 digital seismograph was given to improve the precision of quick report present by Yinchuan Station. The reasons for magnitude error of digital seismograph were also analyzed.
