- 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，M2波潮汐因子均方差及观测资料噪声水平M1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。
This paper analyzed the Current Operational Condition of DSQ Water Tube Tilt meter in Tai'an Seismic Station between 2009 and 2011. Conclusion of this analysis is as following: 1) General quality assessment of the observational data can meet the Specification for deformation observation, and has reached advanced domestic level. 2) Primary wave tidal parameters is stable, both the Mean-Square Deviation of M2 wave tidal factor and the background noise of observation data have reached advanced domestic level, the best Precision is 0.0015.3) The annual variation form is in good consistency, the main interference factors is Calibration.
