周期与阻尼是地震计的两个重要参数,目前,常用阶跃响应波形来测定其数值。本文对阶跃响应波形的时域测定与频域测定两种方法进行了对比计算,结果表明频域测定法的计算精度比时域测定法的计算精度提高约1个数量级。如果研究地震计周期与阻尼参数的影响因素时,应优先选用频域测定法。
Period and damping are two important technical parameters of seismometer, now the values of which are often calculated by step response wave. Time domain calculation and frequency domain calculation of step response wave are contrasted 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 influence factor of seismometer period and damping, the frequency domain calculation should be chosen priory.
