| 摘 要： | 简要介绍了四川地震台网目前使用的4种近震定位程序(HYPO81,Gelor-P、GENETIC、LOC91)，并选取成都数字遥测地震台网记录的30次地震事件，对4种定位程序的定位效果作了初步对比分析。结果表明：对于网内及网缘地震，NYPO81程序的定位结果要稍优于其它3种定位程序；而对于网外地震，4种定位程序得到的结果都不理想。

| Abstract: | Four near earthquake location programs such as HYPO81,Gelor-P,GENETIC and LOC91 presently are used in the Digital Tele-metering Seismic Network of Chengdu.We used the digital data of 30 seismic events recorded in the Digital Tele-metering Seismic Network of Chengdu to test the accurate of locating programs.After the compare among four programs,we think that to the earthquakes inside or near bounder of circle formed by sub-stations of Digital Tele-metering Seismic Network of Chengdu,Program HYPO81 have more precise result of location than that of others and to the earthquakes outside the bounder,four programs do not give the satisfide results. |
