本文首先计算了台湾地区M_L=3.4—5.0级地震的波谱,结果表明,对具有频繁强震活动的台湾地区,大震前后地震波谱没有明显的变化。其次讨论了地震波谱计算的误差,用以量测波谱的F值的计算差为0.25。
In this paper, we first calculate the spectrum of the M_L = 3.4-5.0 earthquake in Taiwan region. The results show that there is no obvious change in the seismic spectrum before and after the earthquake in Taiwan with frequent strong earthquakes. Secondly, the error of the seismic spectrum calculation is discussed. The difference between the F values of the measurement spectrum is 0.25.
