| 摘 要： | 地震波的瞬时信号，如瞬时振幅、瞬时相位等都是研究地球介质的重要参数。本文根据地震信号的特点，选用谐波小波对地震信号进行处理，求出地震信号的奇异点的位置，作出了瞬时振幅、瞬时相位的图形，实例表明，这种方法是可行的。

| Abstract: | The instantaneous parameters of seismic wave,such as instantaneous amplitude,instantaneous phase,are of very important role in studying properties of the earth.In the paper,based on the properties of seismic signal, the harmonic wavelet has been selected and used to deal with to seismic signal ,the position of singularity have been gained and the figure of instantaneous amplitude , instantaneous phase have been made , the instance shows that the method is very practicable. |
