| 摘 要： | 对厦门台DSQ型水管倾斜仪2004—2007年的观测资料作了质量评定，并对影响观测资料精度的主要干扰因素进行了分析。结果表明：1)观测资料的一般性质量评估均满足形变规范要求，达到全国先进水平；2)表征资料内在精度的噪声水平及M2波潮汐因子均方差水平同国内先进台站相比还有一定的差距；3)影响厦门台水管仪观测资料精度的主要干扰因素为海潮干扰。 |

| Abstract: | The tilt data observed during 2004 to 2007 with DSQ water tube tiltmeter at Xiamen seismostation are assessed in quality and an analysis of the main disturbances of the ground tilt observations is made as well.The following conclutions are drawn: 1) The general quality of the observations meets ordinary requirements of deformation surveying standard and reaches the national advanced level.2) There is a certain gap between the noise level and the RMS error of M2 tidal factor and characterizing the inherent a... |
