| 摘 要： | Ｐ＾－波定位方法是针对网内及网缘发生较大震级地震时，地震波记录限幅Ｓ＾＝难以辨认的情况，而编；与的单震相定位程序。该程序可由数字化仪输入地震波到时数据，然后进行定位，定位计算分两步进行，即初定和修定，初定仅根据区域台风提供直达波到时，列出走时方程，将走时方程线性化，解出四个震源参数，为了防止输入的个别错误数据影响定位，采取了图形显示的方法。

| Abstract: | Seismic location by P wave is realized by means of locating program of single phase when a larger shock occurred in or near the seismic station network and S wave was limited signal .The program,firstly,obtains data of arrival time of P wave from the digitalizer,then makes a locating earthguake.The seismic location is divided into two steps which contain preliminary location.and correction The preliminary location gives four focal parameters,then the parameters are corrected by least squares method. |

| Keywords: | Seismic location of Pwave Digitalizer Focal parameter |
