| 摘 要： | DSQ型水管倾斜仪能记录到清晰的倾斜固体潮，根据其观测结果可以考察区域地倾斜状态的变化。鹤岗台水管仪自2006年投入使用以来，为地壳应力应变场研究及地球动力学研究提供了基础资料。对水管仪倾斜潮汐观测资料进行质量评定，确定仪器的稳定状况和M2波γ因子，M1噪声水平指标。并通过功率谱、小波等方法分析影响水管仪的毛刺干扰因素。

| Abstract: | DSQ- Water Tube Tihmeter can record clear tilt tide. According to the observation results, the ground tilt status changes can be measured. Since the water tube tihmeter of Hegang Seismic Station has put into use in 2006, it provided a great deal of data for crustal stress, strain field research and earth dynamics research. Based on the quality evaluation of the tidal information, the instrument stability, M2 wave γ factor and M1 noise level index have been determined. And the burr interference factors of water tube tiltmeter have been found through the power spectrum and wavelet analysis. |
