【摘要】 简要介绍了新安江地震台JB型金属摆倾斜仪和VS垂直摆倾斜仪这两种模拟与数字地倾斜仪器进行记录的情况,并对模拟记录和数字记录的运行率、相关性、噪声水平、稳定性、观测精度等指标进行对比分析,找出数字化观测与模拟观测的差异,为地震台站进一步搞好数字化观测,提高观测精度提供依据。更多还原

【Abstract】 In this paper, the authors briefly introduce the parallel observation of JB type analogous clinometers of metal pendulum and VS type digital clinometers of vertical pendulum in Xin′anjian g Seismic Station. The analogous and digital records are comparative analysis on operating rate, correlation, noise level, stability, and observation precision. The difference between the analogous and digital records is located. The results are useful for the digitalization of seismic station and the improvement of observation precision.更多还原
