| 摘 要： | 应用Snoke最新发展的利用P波、SV波、SH波的初动和振幅比联合计算地震震源机制解的程序，使用一些省地震局数字台网得到的数字波形资料，尝试计算了中小地震的震源机制解，并与原来仅用P波初动得到的结果进行对比研究。结果表明，这种方法是可行的。该方法为数字地震资料在地震预测中的应用提供了一种新的可能。 |

| Abstract: | The focal mechanisms of moderate-small earthquakes are calculated tentatively using digital seismic wave data in some provincial digital seismic networks based on the program of focal mechanism determinations combing the first motion of P, SV and SH waves with their amplitude ratio, which is recently developed by Snoke. Some results are compared with the results obtained by P first motion data. It shows that the method is feasible, and it provides a new possibility using digital seismic data in earthquake prediction. |
| Keywords: | Focal mechanism First motion Amplitude ratio |
