摘　　要：精河地震台DSQ型水管倾斜仪2015年完成升级改造。选取2009—2022年观测数据,采用Venedicv调和分析方法,分析仪器改造前后观测数据精度和监测效能。结果显示,自观测以来,2022年观测数据监测效能最优,精度最高。采用相关系数分析、F检验、T检验、潮汐参数对比等方法,对该年度水管倾斜仪EW、NS分量各端点一致性进行相关分析。结果表明,改造完成后,精河DSQ型水管倾斜仪监测效能逐步提升,观测精度较高,同一分量两端点的相关系数、方差及均值、潮汐参数无显著差异,一致性较高,产出数据稳定、可靠。The DSQ-type water tube tiltmeter of Jinghe Seismic Station was upgraded and renovated in 2015.The observation data from 2009 to 2022 were selected and the Venedicv harmonic analysis method was adopted to analyze the accuracy and monitoring efficiency of the observation data before and after the instrument renovation.The results show that since the observation began,the monitoring efficiency and accuracy of the observation data in 2022 were the best.The consistency of the EW and NS components at both ends of the water tube tiltmeter this year was analyzed by correlation coefficient analysis,F test,T test,and comparison of tidal parameters.The results show that after the renovation,the monitoring efficiency of the Jinghe DSQ-type water tube tiltmeter has gradually improved,the observation accuracy is relatively high,and there are no significant differences in the correlation coefficient,variance and mean,and tidal parameters at both ends of the same component,with high consistency and stable and reliable output data.
