分析嘉峪关西沟形变DSQ水管倾斜仪2008年1月—2010年12月观测资料,利用形态分析法、日均矢量法、M2波潮汐因子动态分析方法，分析水管倾斜仪NS、EW分量，研究观测异常与周边Ms5.0以上中强地震的关系。结果表明，该台水管倾斜仪对周边中强地震有一定短临异常显示，对较远处中强地震也有明显的趋势异常显示。

 Analysis of Jiayuguan Xi Gou deformation of DSQ water tube tiltmeter in 2008 January - 2010 December data, using morphological analysis, the average vector method, the tide factor of M2 wave and dynamic analysis method, analysis of water tube tiltmeter NS, EW component, to study the relationship between observed anomaly and the surrounding more than Ms5。0 of moderately strong earthquakes. The results show that, the water tube tiltmeter is imminent abnormal display on the surrounding medium strong earthquakes, the earthquake distance also has obvious trend anomaly.
