摘　　要：利用南平台ＤＤ－１地震仪所记录到的地核界面反射波ＰｃＰ、地核界面反射转换波ＳｃＰ、ＰｃＳ测定震源深度。结果表明，用这些震相测定地震震源深度，提高了台站测定远震震源参数的精度。he focal depths of earthquakes are determined using the reflected PcP,and the converted ScP and PcS by the nuclear interface,which are recorded by DD1 seismograph in Nanping station.It is indicated that the precision of depth determined by this station is improved for the distant earthquakes if this approach is used.
