基于SSQ-2I型数字石英水平摆与VP型垂直摆倾斜仪2种摆式倾斜仪不同的工作原理，对2018—2020年海拉尔地震台2套仪器的观测数据连续率与完整率、倾斜量年飘零与年变幅、数据观测精度、噪声水平、映震能力等进行对比分析，以对2套仪器的效能进行综合评价。结果表明，SSQ-2I水平摆仪器效能优于VP垂直摆。
Based on the different working principles of SSQ-2I digital quartz pendulum (SSQ-2I pendulum) and VP vertical pendulum tiltmeter (VP vertical pendulum), we analyzed the continuity and integrality of observation data of these two sets of instruments in the Hailar Seismic Station from the year of 2018 to 2020. The annual drift and variation of inclination, the precision of data observation, the noise level, and the ability of earthquake reflection are also analyzed for comprehensive evaluation to the 2 sets of instruments efficiency. The results show that the performance of SSQ-2I horizontal pendulum is better than that of VP vertical pendulum.
