摘要
分析了甘肃宕昌形变台 Ｆ Ｓ Ｑ 型自记水管倾斜仪１９９０ ～１９９８ 年的观测资料．分析结果表明：其潮汐响应函数的测量精度达到了观测规范的要求．水文与气象因素对观测资料有明显影响．该台资料对发生在台站附近的４ 级左右地震有一定程度的短临异常显示；
Observation data of water tube tiltmeter with type FSQ of Tanchang station from 1990 to 1998 are analysed.The results show that observing accuracy of tide response function is in the observation standard.Influence of hydrologic and meteorological factors on observation data is obvious.Short imminent anomalies in a certain extent in the observation data of Tanchang station appear before earthquakes with magnitude of 4 or so in the vicinity of the station and trend anomalies appear before mid strong earthquakes within a distance from the station.
