| 摘 要： | 对2007年12月-2008年9月河南省数字地震台网资料自动量算的震级与人工量算的震级进行了比较和分析。结果表明：由MSDP软件自动量算的震级与人工量算的震级偏差较小，且自动量算的震级可以满足地震定位精度的要求，在地震速报时可采用自动量算的震级。

| Abstract: | In this paper, the deviation of the automatic magnitudes and the artificial magnitudes are analyzed and compared by selecting data recorded by digital seismograph networks in Henan province from Dec. 2007 to Sep. 2008. The results show that the errors between automatic magnitudes calculated by the MSDP software and artificial magnitude are small, and the automatic magnitude can satisfy the requirements of the precious locations of earthquakes. Seismic network report can be used the automatic magnitude. |
