摘要
通过湖州地震台SSQ型数字石英水平摆倾斜仪与SQ-70型模拟石英水平摆倾斜仪2011年1月—12月对比观测,得出数字与模拟观测资料以地球固体潮为分析参照,两种观测数据基本一致,潮汐幅度也基本一致。
The comparison of SSQ digital and SQ-70 analogue observations of the quartz pendulum tiltmeter at Huzhou Seismic Station in 2011 shows that, consulting the Earth tide, the two observations are basically consistent, and the tide amplitudes are also basically the same. The stability of digital observation instrument is higher than that of analogue observation.
