摘　　要：分析了发生在厦门地震台周边的三次地震在地形变仪器上的不同反映,探讨了倾斜仪与伸缩仪对同一地震的监测能力的差别。结果表明:①同一异常并非在所有的仪器上都能表现出来,即使在同一观测仪器的不同分量上也会有不同的表现;②不同的地震在同一仪器上表现出来的异常是不同的,厦门地震台水平摆的异常形式有两种——日均值曲线畸变与记录曲线错动;③仪器的监测范围与未来震级的大小有关系。We analyze the records of three earthquakes around the Xiamen seismic station of Fujian observed by the ground deformation seismograph at the station, and discuss the ability that the tilter and tensometer monitor the same earthquake. The results are as follows： （1） Not every instrument can show anomaly, and the same anomaly may have different performance even on the different components of an instrument. （2） The abnormal performance on the same instrument varies with earthquakes. The anomalies recorded by the level pendulum tilter have two kinds of shapes： the distortion of daily mean curve and the stagger of raw recording curve. （3） The monitoring scope of equipment is related to the size of the magnitude of earthquake.
