摘　　要：以西安地震台记录的2001—2018年13次6级以上极远震为研究对象,依据AK135走时表进行震相分析,总结归纳典型极远震震相记录特征,以期提高震相分析水平和测震分析工作质量,为其他地震台站极远震分析工作提供借鉴。Based on more than 6 magnitude ultra-distant earthquakes recorded by Xi’an Seismic Station from 2001 to 2018 years,in this paper we analyze the seismic phase according to AK135 travel time table,summarize the recording characteristics of seismic phase of typical far distant earthquakes,and further improve the understanding of seismic phase characteristics and analysis method for far distant earthquakes recorded by Xi’an Seismic Station.These results can better guide analysts to analyze far distant earthquakes,and also have some reference significance for other seismic stations.
