【Abstract】 In this paper, the typical character of JCZ-1 ultra broadband digital seismometer shown in seismic record at Wuhan station is discussed and analyzed. After comparing with the simultaneous observation results obtained from the analogue record seismometer (short, middle and long period), it shows that the seismic phases of JCZ-1 are clear and rich even more. The application of the JCZ-1 to the seismic observation can obviously raise the monitoring ability of seismostation and the quality of quick report for large earthquakes.更多还原
