内蒙古地震台网与呼和浩特遥测台网ML震级的归一化研究

对内蒙古地震台网和呼和浩特遥测地震台网测定的近震震级ＭＬ的偏差进行了统计研究，结果表明；两者之间的ＭＬ震级标度基本一致。由于ＭＬ震级公式本身的不均匀性，对于网外地震，遥测台网ＭＬ震级需加适量校正值。

The normalized investigation for M L magnitude between the Huhhot telemetered seismic network and seismological network of Neimonggu

The telemetered network and the seismic stations are two seismic observation systems in China some region earthquake lists are digested by the telemetered network data, some region lists by the station data and some lists by both data. In this paper, we have studied the M L magnitude deviations between the telemetered networks and the seismic stations. The results indicated that the M L magnitude scale of two systems are fundamental unification. For the earthquakes occurred with in the telemetered networks and in the edge area of the networks, the M L magnitude scale in the list of two systems is unified; for the earthquakes out of the telemetered networks, need a correction value. The value of the Huhhot telemetered network is L =-0.3. We think this correction value be caused by the nonhomogeneity of the M L magnitude formula.
