摘　　要：通过分析2007年福建顺昌ML4.9级地震、2011年日本MS9.0级地震这两次地震前后莆田地震台体应变观测资料,并对固体潮畸变异常现象进行了讨论。结果表明:异常与常见的外界干扰有明显区别,应为地震前兆异常。The paper analyzed the body strain observation data of putian seismic station before and after the Fujian Shunchaong ML4.9 earthquake in 2007 and the Japan MS9.0 earthquake in 2011, and discussed the distortion of the tidal anomalies, The results show that： the anomaly and the common interference are significantly different, which should be the earthquake precursory anomaly.
