| 摘 要： | 使用振幅比法计算地震的震源机制解软件，要求条件低、计算简便易行，可满足地震台网在地震速报中同时提供震源机制解参数的需要，利用山西数字遥测地震台网考核运行期间的数字记录资料。进行了震源机制解的速报与分析，结果表明，虽然山西数字遥测地震台网运行的时间很短，能够计算震源机制解的地震有限，但是结果仍可显示出受华北构造应力场一定的控制作用，半数中小地震的震源机制解和华北强震的震源机制解相同。

| Abstract: | The software using method of amplitude ratio can compute source mechanism easily in less limitations. It can give both earthquake location parameter and source mechanism solution. The source mechanism solutions are made with the digital records from the Telemetric Digital Seismic Network of Shanxi Province during its test operation. The number of earthquakes that their source mechanism solutions can be got is not so large due to short run time of the network. The result, however, shows that these source mechanism solutions are related to the structure stress field in the northern China. More than 50 % source mechanism solutions for small and middle earthquakes are identical to the solutions for large earthquakes in North China. |
