| 摘 要： | 宁波地震台地处沿海,受海潮影响较大,地倾斜仪所记的东西、北南向固体潮在同一数量级上,与日月形成的理论固体潮汐、海水潮汐同步变化。用该台的地倾斜资料的分钟值描绘矢量图,发现每日的矢量图规律性强,并且在地震前有一定的异常表现。

| Abstract: | Ningbo seismostation is located in the coastal area and obviously influenced by the oceanic tide.The earth tide in the directions of EW and NS recorded by tiltmeter is at the same level.The vectorgraph drawn by using the minute values of the tiltal data is quite regular and has some anomalies before earthquake. |
