笔者在工作中发现，使用地震台站、区域地球物理台网、国家台网地震地球物理监测数据库中同一台站、同一测项、相同时段监测数据绘制曲线，存在曲线不一致现象，分析认为，存在差异的原因主要是，数据经审核、反馈、处理，再次上传各库过程中未及时核对、及时发现、及时覆盖，省地震局区域地球物理台网需定时检查、同步各库数据。
In this paper, the authors came across the phenomena of inconsistencies of data observed at the same seismic station for the same monitoring item and period of time which were stored respectively in the databases of the seismic station, regional geophysical network and national geophysical network. Analysis showed the main reason for the difference was that in the process of data review, feedback, processing and re-uploading to each database, there were lack of timely check and overwrite, the solution scheme is to check and synchronize the data of each database regularly in the regional geophysical network.
