本文选取了福建、陕西的12次爆破事件，安徽台网的6次速报地震事件以及4次有地震台站出现GPS时钟错误的地震事件，运用两种地震定位方法进行定位，并将其结果进行比较。结果表明：对于网内地震，HYP02000程序的定位结果稍优于单纯形的定位结果；对于网缘及网外地震，则单纯形的定位结果要优于HYP02000程序的定位结果。

 In this paper,12 explosion events occurred in Fujian and Shanxi,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 simplex ;but for the earthquakes occurred not in the network,the results given by simplex are better.
