通过对连云港地震台BBVS-120、CTS-1E型地震计台基噪声功率谱分析,正弦标定和脉冲标定计算分析,近震和远震震级对比分析,研究在实际工作中2种地震计性能差异,对比观测数据质量,检验稳定性,以期为地震监测及相关研究工作提供依据。
In this paper, the background noise power spectral density of BBVS-120 and CTS-1 seismometers at Lianyungang Seismic Station is analyzed, the sine calibration and pulse calibration are calculated and analyzed, and the magnitudes of near shocks and teleseismic events are compared. Through comparing the quality of observation data and the stability of two sets of seismometers, the performance difference of the two seismometers is analyzed, aiming to provide some useful information for further seismic monitoring and corresponding study.
