摘　　要：利用沈阳台测算震级与国家台网速报标准震级进行比较,寻找存在震级差的原因,分析得出,台站测算震级存在误差的原因主要有震中距,方位角,地震震级等。Based on the statistics of the report earthquake magnitude at Shenyang Seismic Station and compared with China Earthquake Networks, the magnitude difference factors have been found out in this paper. It is concluded that the magnitude error calculated by seismic station is mainly caused by the epicentral distance, azimuth, magnitude, and so on.
