In this article, calculating the power spectrum density of station base noise and processing the calibration data of sine signal, especially the phase analyzing of observations of BBVS-60 and KS-2000 seismograph systems in Lu an Seismic Station, the difference in performance of two type broadband seismographs is comparatively analyzed, in order to provide technical support for the earthquake record analysis and instrument maintenance%通过对六安地区BBVS-60与KS-2000地震计系统记录台基噪声功率谱密度计算,和正弦标定数据处理,尤其通过对仪器系统记录地震震相分析,比较两种类型宽频带地震计系统的性能差异,为台站地震记录震相分析与仪器维护提供技术支持.
