对琼中地震台两套记录仪标定日连续多组基线值观测数据作对比分析，结果表明，该台两套记录仪日变化记录曲线一致性较好，测量误差除 G M3偏角外，均满足《数字地磁台网观测资料质量评比办法》要求，基线值变化幅度稍显起伏，但能够真实反映地磁场日变化状态；标定时段内两套仪器间的基线值有一定差异，但不影响观测数据的可靠性。

Some groups of baseline values are comparative analyzed between FGE magnetometer and GM3 magnetometer during the calibrating time in Qiongzhong.The results show that daily variation curves recorded by the sets are better consistency,and in addition to GM3 magnetic declination,the measurement error are to meet “The assessment methods of digital geomag-netic observation data quality”.Although variable amplitude of the baseline values are slightly up and downs but they are able to truly reflect the state of daily variation of the geomagnetic field.The baseline values are some differences between the two sets during the calibrating time,but it does not affect the reliability of observational data.
