引言①长期以来，地震分析人员一直沿用从地震记录图纸上读取地震震相的方法。由于其精度低、效率差，在一定程度上限制了地震速报及日常分析工作的进一步发展。近年来数字地震台网的发展成为测震技术的新里程碑，给地震测震工作带来了喜讯。但由于其本身的高技术要求及昂贵的
Introduction ① For a long time, seismic analysts have been using the method of reading the seismic phases from the seismogram. Due to its low accuracy and poor efficiency, to a certain extent, the further development of earthquake quick report and routine analysis is limited. In recent years, the development of digital seismic network has become a new milestone of seismic technology, which has brought good news to seismic seismics. But due to its own high technical requirements and expensive
