| 摘 要： | 延庆地震台五里营井动水位2010年1月13日15时48分突然大幅下降，7min下降0．47m，针对此异常变化，台站人员通过检查仪器运行、观测环境等多方面查找原因，逐项排除干扰因素，最后通过科学、系统的分析，判定此异常是由于地下泄流管破裂，造成水位迅速下降，非地震前兆异常，避免了误报地震，为水位异常判断积累了一定经验。 |

| Abstract: | The water level of Wuliying well at Yanqing Seismic Station suddenly declined 0. 47 m in 7 minutes at 15：48 on Jan. 13, 2010. We eliminated the interference elements by checking the instrument working status, the observing environment and other conditions. We gained the conclusion which was because the drainage-tube underground had broken but not the earthquake abnormality, and offered the foundation for the earthquake abnormality judgment, avoiding misreport the earthquakes. |
