摘　　要：从一致性和相关性等方面对宿迁地震监测中心站体应变仪传感器更换前后两组观测资料进行对比分析。研究两组数据之间的关联性发现,新体应变仪观测系统稳定,观测数据可靠,与原体应变仪历史数据具有高度的一致性和相关性。体应变仪传感器更换前后两组数据可作为连续关联系统的整体数据用于该区域地壳应变场研究。From the aspects of consistency and correlation,we compare and analyze the observation data of the two sets of volumetric strain gauges before and after sensor replacement in Suqian earthquake monitoring center station.We find that the observation system of the newly installed volumetric strain gauge is stable,the observation data are reliable,and the observation data are highly consistent and correlated with the historical data of the original volumetric strain gauge.We consider that the two sets of data before and after the replacement can be regarded as continuous and correlated whole data for the study of crustal stress-strain field in this region.
