Since increasing channel capability in seismogram and length of spread, the apparent velocities of seismic useful waves are reduced in the far-offset traces and suppressed in different degree by geophone array, even more serious for high-frequency useful signals.

但由于地震仪带道能力增强，排列长度加长，使地震有效波视速度在远道减小，并受到不同程度的检波器组合压制，尤其是对高频有效信号的压制更为严重。

Several seismic input models of power spectrum corresponding to the target response spectrum are studied and used to frequency response analysis of single-degree-of-freedom system.
