| 摘 要： | 为了快速而精确地确定震源位置，尽可能减少定位所产生的误差，引入了求解准则函数极小值的“POWELL”方法、“模拟退火法”、求解震源深度的“PTD方法”和“翻台法”用于近震定位。本文利用上述方法编制了近震定位程序，经过理论和实际应用的严格考察，已在全国部分数字化地震台网中推广使用，效果较好。

| Abstract: | In order to locate the focus position quickly and accurately,and reduce the errors due to locating earthquakes as far as possible,we apply POWELL method and simulated annealing method which are used to get the minimum of criterion function,PTD method which is used to get focus depth,and reverse station method to locate regional earthquakes.The authors of this paper have compiled a program for locating regional earthquakes based on the methods mentioned above.The program has been tested theoretically and practically,and now is disseminated and applied in some digital seismic networks all over the country,with very good results. |
