摘　　要：对同址观测的地震计所记录的安静时段背景噪声、天然地方震、远震事件分别进行MISFIT分析,并参考MISFIT-GOODNESS的结果,给出两台地震计记录一致性的评价,对基于不同目的波形分析给出使用记录波形的合理频段范围,提高数据应用的可靠性。We analysis the waveform recorded by the collocated seismometers during different time including the low background noise level,local earthquake and teleseismic through MISFIT.MISFIT-GOODNESS is combined with the MISFIT to give the evaluation of consistency for the collocated two seismometers.The reasonable frequency band to wave based on different applications will be offered to improve the reliability for the application of waveform.

关 键 词：同址 MISFIT MISFIT-GOODNESS 频段 可靠性
