摘　　要：依兰地震台DSQ水管倾斜仪和通河台VP垂直摆2套数字化地倾斜观测仪器结构和原理差别较大,但观测的物理量一致。该文从数据连续率、相关性、同震效应及降雨等角度出发,对数据进行对比观测分析。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。The structure and principle of two sets of digital ground tilt observation instruments at Yilan Seismic Station DSQ water pipe tiltmeter and Tonghe Station VP vertical pendulum are quite different,but the observed physical quantities are the same.From the point of view of data continuity,correlation,coseismic effect and rainfall,this paper makes a comparative observation and analysis of the data.The results show that the stability of the two instruments is strong,the data integrity rate is high,and the variation law of ground tilt is the same.All this can reflect the variation characteristics of earth tilt in the monitoring area,and the annual variation trend is obviously disturbed by rainfall.
