摘　　要：对河南数字测震台网2012年1月—2013年4月记录到的80个地震事件,在震级方面分别做了仿真前和仿真后的对比分析,给出其偏差。结果表明:仿真后的震级多数大于仿真前的震级,但震级差均在0.3级以内。对于速报时可不采用仿真震级。但对于编目和研究人员可采用仿真震级。In this paper, the deviation of the velocity magnitudes and simulated magnitudes are analyzed and compared by selecting data recorded by digital seismic network in Henan province from Jan. 2012 to April 2013. The results show that most of simulated magnitudes were bigger than velocity magnitudes, but the magnitude deviation is under 0.3 magnitude. Seismic network report couldn’t be used in the simulated magnitude. But catalogers and researchers can use the simulated magnitude.
