摘　　要：以嘉祥地震台2014—2020年记录的418个6级以上极远震震相为研究对象,基于AK135走时表,选取其中10个典型震例,分析研究区域内极远震震相记录特征,结果表明:记录震相因地震发生地区而异,主要影响因素为震中距、震源深度、震级等。Taking 418 ultra-distant seismic phases of earthquakes of magnitude 6 and above recorded at the Jiaxiang Seismic Station from 2014 to 2020 as a research object,the study selects 10 typical earthquakes to analyze their seismic phase characteristics by using the AK135 travel time table.The results show that the number of seismic phases varies from region to region,and the main influencing factors are epicentral distance,focal depth,magnitude,etc.
