| 摘 要： | 对白银形变观测站2008年以来观测资料的运行、变化和噪声水平做初步分析，结果表明：DSQ 型水管倾斜仪观测资料连续、稳定、可靠具有明确的正常背景---夏高冬低，为今后地震前兆异常的判断打下基础；水管倾斜仪 EW 分量在2013年7月22日 MS 6．6地震前出现破年变变化，说明白银地震台水管倾斜仪具有一定的地震前兆异常监测能力。

| Abstract: | Water tube tilted instrument at seismological observatory of Baiyin was installed in 2006, it started trial operation from October to December in 2007.It began to output formal observation data in January,2008.We have produced continuous,reliable,stable observation data for more than 5 years.We will make a preliminary analysis for the operation,changes and precision since the observation data of 2008. |
