摘　　要：选取福建、陕西的12次爆破事件,安徽测震台网的6次速报地震事件以及4次地震台站出现GPS时钟错误的地震事件,运用两种地震定位方法进行定位。结果表明:对于网内地震,HYPO2000程序稍优于单纯形定位结果;对于网缘及网外地震,单纯形优于HYPO2000程序的定位结果。In this paper, 12 explosion events occurred in Fujian and Shanxi Provinces, 6 quicK report earthquake events of Anhui Seismic Network and 4 earthquake events which have a wrong GPS time station are selected and analyzed using the two earthquake location programs. The results show that： for the earthquakes occurred in the network, the results given by HYPO2000 are slightly better than that given by simple; but for the earthquakes occurred not in the network, the results given by simplex are better.
