| 摘 要： | 云县地震台架设DSQ水管倾斜仪和VP垂直摆2套数字化地倾斜观测仪器,2套仪器的结构和原理差别较大,但观测的物理量一致。本文从数据完整率、内在精度、年变幅度、相关性、形态特征等角度出发,对数据进行对比分析,结果表明:2套仪器稳定性均较强,数据完整率较高,且地倾斜变化规律一致,均能反映监测区域大地倾斜变化特征,年变趋势受降雨干扰明显。

| Abstract: | Both DSQ water-tube tiltermeter and VP vertical pendulum tiltermeter installed at Yunxian Seismic Station are digital instruments for tilt observation, with same physical measurement, but different structures and principles. We analyzed contrastively the integrity rate, inherent accuracy, annual variation, correlation and morphological characteristics of data recorded.The results show that the DSQ water-tube tiltermeter and VP vertical pendulum tiltermeter are stable, the data recorded are complete, the change characteristics of two sets of tiltermeters are consistent. They can reflect well the change characteristics of the tilt in the observation region and the obvious influence of rainfall on annual variation trend of recordsl. |
