摘　　要：主要对2002年度我国地磁台网GM3磁通门磁力仪的观测数据的完整率及影响因素进行了统计分析,并以昌黎台为例进行了详细的解释说明,从而对台网及台站数字观测数据的完整率及影响因素有了较深入的了解,并根据统计分析结果,对台站观测日志的存储内容和存储方式提出了改进意见。The integrality of data recorded by GM3 fluxgate magnetometers in Geomagnetic Observa-tory Network in 2002 and its influence factor are studied in this paper. As an example, the digital data and its influence factor observed by Changli Geomagnetic observatory are dis-cussed in detail. At last, some advice for the method to save the observing log are proposed according to the analysis result.
