山西临汾中心地震台地倾斜模拟与数字化观测资料的对比分析

Comparative Analysis on Analog and Digital Observation Data of Ground Tilt of Linfen Central Seismological Station

文章介绍了山西临汾中心地震台JB型金属摆倾斜仪和SSQ—2I数字化石英摆倾斜仪两种仪器记录的情况,对模拟记录和数字记录的运行率、相关性、稳定性、观测精度等指标进行对比分析,找出数字化与模拟观测的异同点,为进一步搞好数字化观测,提高观测精度,实现数字化与模拟资料的衔接提供参考依据。

JB metal pendulum tiltmeter and digital SSQ--2I quartz pendulum tiltmeter installed at Linfen Central Seismological Station, Shanxi, are introduced in this paper. The operating ratio, correlation, stability and observation precision of analog and digital records are analyzed comparatively for figuring out similarities and differences between the analog and the digital, which can provide evidences for making digital observation better, improving observation precision and connecting between digital data and analog data better.
