摘要
本文对和达曲线法鉴别近震直达P波和直达S波的原理进行了详细的讨论,得出确定和达曲线参数的基本公式及用来表示S-P到时差与P到时线性相关程度的相关系数r的计算方法。讨论了利用和达曲线在台网定位中的应用方法。最后研制了利用和达曲线提高震相识别精度的应用程序,并以实例说明该程序的用法。
The theory to distinguish P wave and S wave in local events through Wadachi method was discussed in this paper. We got the basic formula and calculating method which could be used to express correlative coefficient r of s-p and p onset. We discussed the application of Wadachi method in seismic net to locate local events. We developed the software to improve precision of local earthquake locating through Wadachi method and showed how to use this software by some examples.
