摘　　要：对溧阳地震台体应变观测资料变化形态、观测质量和观测精度、潮汐因子中误差、地震波记录能力等参数进行分析,采用固体潮汐残差矢量分析方法进行分析,对该台2010—2015年观测资料进行分析,发现体应变能记录到全球不同地区、不同震级的同震波,波形清晰,为分析预报人员进行地震研究提供依据。In this paper,the variation pattern,observation quality and observation accuracy,tidal factor error,seismic wave recording ability and other parameters of body strain observation data at Liyang Seismic Station are analyzed.Using vector analysis method of solid tide residuals,the observation data of Liyang Seismic Station from 2010 to 2015 are studied.It is found that the bulk strain observation at Liyang Seismic Station has the capability to record the coseismic wave of the earthquakes with different magnitude and in different region of the global earth,and provide significant information for the analysts and forecasters of seismological investigation.
