摘　　要：通过对安装在山东省临沂市马陵山比测基地的GL-S120与3T-120两种甚宽频带地震计观测数据对比分析,得到这两种地震计之间的相关系数、地动噪声、地震计自噪声等性能的数值指标,为地震监测及其他相关工作提供参考。In this paper,the comparative observation of the GL-S120 and 3T-120 very wideband seismometers installed in the Maling Mountain Comparison Base in Linyi City,Shandong Province,is conducted to study the correlation,geodynamic noise,and actual dynamics between the two sets of observation systems.The performance differences of the observation range and seismometer self-noise provide a certain reference for future seismic monitoring and other related work.
