摘要
利用德令哈地震台DD-1记录到的746个近震,对其测定的震级偏差进行统计计算,发现DD-1测定的震级偏小。经过分析,指出了产生偏差的原因,并给出了校正值C=+0.15。
The magnitude deviation is statistically calculated by 746 local earthquakes recorded by DD-1 at Delingha station, and it is found that the magnitudes by DD-1 are smaller. The deviation is analysed and the correction value is given out, C=+0.15.
