| Abstract: | The kinematics and dynamics characters of Pdif phase in seismic wave from 31 far-teleseism recorded by the broad band digital seismic instruments at CDSN Lanzhou seismic station during 1990-2000 are analyzed. The travel table of Pdif wave at CDSN Lanzhou seismic station is offered for analyzing conveniently. The result is very useful to enhance the rapid earthquake information report ability and accumulate seismic phase analysis experience. It is also helpful to understand physics characters of mantle-core border inner the earth. |
