摘要

对泰安地震台2009—2010年伸缩仪运行现状进行分析,对运行故障进行排查。从资料连续率、稳定性、潮汐因子中误差和相对噪声水平等方面进行评定,与2000—2008年"九五"数据进行对比和分析。结果表明:①观测资料的连续性和稳定性基本满足形变观测要求;②表征固体潮内在质量的M_2波潮汐因子均方差及观测资料噪声水平M_1完全满足形变规范要求,精度(加权平均)达到0.0098;③对资料的日变、年变、干扰等进行分析。
A quality assess of continuity,stability,error and relative noise level of tide factor and so on was carried on to the data of SS-Y extensometer during 2009—2010 at Taian Fiducial Seismic Station(TFSS).After the comparison of the fore mentioned data and data from 2000 to 2008,the following three aspects was concluded.1)Basically,the continuity and stability of the observation data stratify the deformation observation standard;2)The mean-square difference of factor of M_2 wave which represent the inner quality of solid tide and the noise level M_1 of the observation data satisfy the deformation observation standard,the precision (Weighted average)is 0.0098;3)The diurnal change,annual change and disturbance is analyzed. Certain problems appears during the operation process is discovered and solved.
