摘要

通过基于COM组件的VB与Matlab混合编程途径,实现已知区域P波速度条件下利用多台P波到时估测震中位置算法程序化,使用发现,该程序具有运行界面友好、速度快及对网内和网缘地震定位精度较好的优点。
We briefly analyzes the algorithm of using multiple station P-wave arriavl time under two conditions(regional P-wave velocity is known and unknown),using search method(also known as grid method) to estimate the epicenter,in this paper firstly.COM components based on VB and Matlab mixed programming is used to achieve the algorithm of estimate the epicenter by the regional P-wave velocity.In actual usage,we found that the program had advantage of interface friendly,run fast,and earthquake location precision,when the earthquake occurs in and in the edge of the net.This algorithm provides an auxiliary means to estimate the epicenter by use of multiple station data.
