摘　　要：以中国地震台网测定的综合体波震级为标准震级,采用正交回归方法,得到南京测震台(NJ2)体波震级与标准体波震级之间的关系式,并对震级偏差与震级大小、震中方位和震中距关系进行偏差分析,为台站分析人员提供指导。By using orthogonal regression method, a systematic comparison has made between body wave magnitudes determined by Nanjing Seismic Station and China Earthquake Networks Center on the basis of observation data from them during 1985 to 2010. Focused on the causes resulted in magnitude deviation, we analyze the relationships among magnitude, azimuth and distance. Then we have gotten conclusions that could server for researchers.
