| 摘 要： | 分析了2011年以来天祝台阵景泰芦阳台水温观测资料，芦阳井水温具有较规律性的年变化动态趋势。排除仪器故障、人为干扰及降雨等因素后，认为2014年11月15日甘肃景泰MS4.7地震前芦阳水温出现了前兆异常。排除干扰方法、过程及排除干扰后的观测资料应用，能为观测资料跟踪分析提供参考。

| Abstract: | Based on the observation data of water temperature at Luyang, Jingtai since 2011, we found the change and dynamic trend of water temperature of Luyang well has annual regularity. After eliminating interference factors of instrument failure, human disturbance and rainfall etc, we found some anomalies before the MS4.7 Jingtai earthquake in Gansu. The method and the process of eliminating interference, and the application of the observed data after eliminating the interference can provide reference for tracking and analysis of the observation data. |
