摘　　要：从干扰因素、连续性、稳定性、观测精度和映震能力等方面对银川台同台基的SQ-70D石英水平摆倾斜仪与VP宽频带垂直摆倾斜仪2019年1—7月产出数据的进行对比分析研究后,检验出VP垂直摆在连续性、稳定性和映震能力等方面明显优于SQ-70D石英摆,但对于观测精度而言,SQ-70D石英摆高于VP垂直摆。In order to comprehensively evaluate the operational performance of the SQ-70D type analog quartz horizontal pendulum tiltmeter and VP broadband vertical pendulumin placed at the same observation site in 2019-1~7,multiple perspective analysis and comparison,from the aspects of interference factors,continuity,stability,observation precision and earthquake reflecting ability are comparative analyzed.The test shows that the VP vertical pendulum is superior to SQ-70D quartz pendulum in continuity,stability and reflecting earthquake ability,but SQ-70D quartz pendulum is superior to VP vertical pendulum in observation precision.
