摘要
依据长春地震台数字测震资料,计算了不同震中距地震波形的振幅谱,并对主要震相的频率特性进行了初步分析。
On the basis of the digital seismographic record of Changchun seismic station,the amplitude spectrum in different epicentral distance was calculated and the amplitude frequency characteristic of the main seismic phase was analysed preliminarily in this paper.
