| 摘 要： | 讨论了成都台测定震级与中国地震台网中心(CSN)发布的MS震级的偏差,分析了仿真SK、仿真763与(CSN)震级的偏差程度,并给出了校正值。通过分析,得出了仿真763的面波震级MS7的偏差远远小于仿真SK的MS结论,因此,在速报中,应尽量使用MS7面波震级,有利于提高速报震级的准确性。

| Abstract: | Firstly the reliability of the seismic magnitude the deviation from the one of China Seismic Network are practice the data for determining the seismic magnitude determined by the Seismic Standard Station of Chengdu and discussed. Then the corrective value is put forward. In the should be the travel time of surface wave. |
