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 DD1 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.
