摘　　要：对山西省代县、太原、侯马地震台数字化水管倾斜仪2008年1月—2010年10月的观测资料作质量评定,阐述其台址条件,找出水管倾斜仪的日变规律,精确计算各台站连续率、完整率、内精度、噪声水平、年零漂、年变幅;对影响观测质量精度、观测资料的主要因素进行分析,排除干扰,识别地震异常,为今后提升各台站观测资料质量,提供参考。The quality of tilt data observed with DSQ water rube tiltmeter at Daixian, Taiyuan, Houma seismic stations during January 2008 to September 2010 are assessed. Analyzing the site environment, finding the daily variation law of the water tube tiltmeters, precisely calculating the continuity ratio, full rate, the accuracy, noise level, the annual zero-shift and an nual amplitude variation of each machine, the main factors to influence the quality and precision of observation data are analyzed. The interferences in observation data are eliminated and the seismic anomalies are identified. The results provide a reference for improving the quality of observation data at each station in the future.
