摘　　要：通过对GL-S60、GL-CS60与3ESPC三种宽频带地震计进行对比观测,分析3套观测设备的相关性、地震计自噪声、短周期噪声、长周期噪声等性能,并对3套系统产生的差异进行探讨,希望对以后地震计的研究提供一定参考。Through the comparison and observation of three kinds of wide-band seismometers(GL-S60,GL-CS60 and 3ESPC),the correlation,self-noise,short-period noise and long-period noise of the three sets of observation equipment were analyzed,and the differences between the three sets of systems were discussed,hoping to provide some reference for the study of the seismometers in the future.
