摘要
把遗传算法应用于地震定位，并与Ｐｏｗｅｌｌ算法和传统算法进行了比较，结果表明，遗传算法在地震定位中所给出的发震时刻精度较高，震源深度较可靠，对非 包围地震定位效果较好。
The genetic algorithm is applied to seismic location, and its results are compared with those of Powell algorithm and traditional algorithm. It is shown that when genetic algorithm is used, the precision of determined origin time is higher and the determined depth is more reliable. This method is better when the stations concentrate on one side of an earthquake.
