    对阶跃响应波形的时域测定与频域测定两种方法进行对比计算，结果表明，频域测定法的计算精度提高约1个数量级。研究地震计周期与阻尼参数的影响因素，应优先选用频域测定法。

    Time domain calculation and frequency domain calculation of step response wave are con-trasted in the paper.The result shows that the precision of frequency domain calculation is one magnitude higher than the precision of time domain calculation.When studying the in-fluence factor of seismometer period and damping,the frequency domain calculation should be chosen preferably.
