摘　　要：分析泰安地震台DSQ水管倾斜仪2009—2011年运行现状,与"九五"数据进行对比检验,结果表明:观测资料的一般性质量评估均满足形变观测规范要求;各主波潮汐参数稳定,M_2波潮汐因子均方差及观测资料噪声水平M_1满足形变规范要求,最高精度达0.0015;年变形态一致性较好,标定干扰影响较大。In this paper, the current operational condition of DSQ Water Tube Tilt meter in Taian Seismic Station between 2009 and 2011 is analyzed. Conclusion of this analysis is as follow- ing. ①General quality assessment of the observational data can meet the specification for de- formation observation, and has reached advanced domestic level;②Primary, wave tidal pa- rameters is stable; both the mean-square deviation of M2 wave tidal factor and the back- ground noise of observation data have reached advanced domestic level; The best precision is 0. 0015;③The annual variation form is in good consistency; the main interference factor is calibration.
