摘要
使用肇庆地磁台2005年dIdD矢量磁力仪与GM3磁通门磁力仪的观测数据,系统地分析了两套仪器分钟值、日均值、基线值的变化趋势。根据均值和方差检验以及基线值的变化趋势,认为两套仪器有相同的观测精度,除了均值有较小的差异外。两套仪器的观测数据无系统偏差,仪器的稳定性和数据的一致性较好。
In this paper, by using the observed data in 2005 from GM3 fluxgate magnetometer and dIdD vector magnetometer at Zhaoqing Geomagnetic Observatory, we systematically analyze the variational tendency of minute values, daily mean values and baseline values of the two instruments above. According to the mean values and variance inspection and baseline variational tendency, we think that both instruments are of the same observation precision except small difference in mean values. Both have no systematic deviation and are good in instrument stability and data consistency.
