【摘要】 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。更多还原

【Abstract】 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 preferably.更多还原
