| Abstract: | In this paper,the recording character of Pdif phase of 63 far-teleseism observations recorded by broad band digital seismic instrument of CDSN Beijing Seismic Station during 1990- 2008 is analyzed. At present, the Pdif phase was recorded among epicenter distance is 101.87°-172.18°. The minimum magnitude is about 6.0. The minimum of earthquake source depth is about 9km, the maximum of earthquake source depth is about 631.3 km. The result was very useful to enhance the earthquake analysis ability and accumulate analysis experience. It is very helpful to understand physics character about mantle-core border of the earth. |
