摘　　要：聊兰断裂带小震较多,周围台站记录该地区地震震相特殊.濮阳市地震台搜集了该区域有这一特征的地震,依据本区地质构造特征和地震波运动学特征,运用对比法、作图法和时距方程法,分析了该区域特殊震相特征,认为两个不明震相为地下界面反射波.There are many small earthquakes in the Liaolan Fault Zone,and the seismic stations around the area recorda special seismic phase. Puyang seismic station record some earthquakes in this area which have the character. Withthe help of comparative method,graphic method and time distance equation method,we analyzed the seismic phasecharacteristics in this area according to the characteristics of geological structure and seismic wave kinematics,proposed that the special seismic phase is underground interface reflection wave.
