摘　　要：为快速获得中强地震可靠的震源机制解等震源参数,设计并研制了基于CAP方法的震源机制解交互反演软件(SeisCAP)。软件具有图形界面,可直接读取区域地震台网观测波形,交互挑选反演台站,自动开展观测波形处理、理论地震图计算和震源机制解反演。通过不同构造环境、不同震级和不同类型的多个中强地震事件测试,结果表明该软件具有可靠性和稳健性。该软件易使用,便于在中强地震发生后快速获取震源机制解,为地震应急和震源研究提供数据和资料。In order to obtain reliable the source parameters quickly,such as focal mechanism solutions for mid-strong earthquakes,an interactive inversion software based on CAP method is designed and implemented.The software has a graphical interface to read the earthquake waveform from regional seismic network.Stations used for inversion are selected by user.Then the software can be used to automatically process the observed waveforms,calculate the theoretical Green's function and invert the focal mechanisms of the earthquakes.It is proved that the software is convenient,reliable and robust by testing multiple earthquakes with different tectonic environments,different magnitudes and different types.The software is easy to quickly obtain focal mechanism solutions of the intermediate or strong earthquake.It is significance to provide the solutions data for emergency response,and it is beneficial to the study on seismic source properties.
