介绍了甘肃省宕昌形变台ＦＳＱ型浮于水管倾斜仪１９９０．７～１９９４．３期间的测量结果，分析了该台倾斜固体潮潮汐因子和非潮汐曲线及其残差曲线的动态特征。
In this paper the results of Dang Chang Deformation station measured by FSQ--type water tubetiltmeter during 1990. 7～1994. 3 was introduced. The dynamic performance of the results is analysed.The results show that the mean square error of hour's reading values is less than 1 × 10-3'; the monthlyvariation range of tidal factors of O1 and M2wave is less than 6 %. Among the drift curve, there are threecomponent parts, namly: long series tendency component, annual variation component and residual component. The variational speed rate of the tilt vector in the long period component is 1. 5'/a, and the direction towards S11°E. After 1992, there is an obviously anomaly in the non - tide residual curve. During1993～1994 the variation speed rate of the residual vector is 0. 5'/a, and the direction toward N36°E.
