Pdif震相在CDSN兰州地震台的记录特征
The Recording Characters of Pdif Phase in Seismic Wave at CDSN Lanzhou Seismic Station
【摘要】 通过对CDSN兰州地震台1990-2000年间31个极远震记录的分析,得到了Pdif震相在CDSN宽频带数字地震仪上的运动学和动力学特征;给出了兰州地震台Pdif震相走时便查表,以便分析时查询比较。所得结果有助于提高地震速报能力和积累震相分析经验,有助于对核幔边界物理性质的认识。
【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.
