摘要
从理论上定量地分析了 FHD- 1型分量核旋仪的偏置电流对磁偏角观测值的影响 ,结果表明偏置电流的漂移对磁偏角观测值的影响随偏置电流的漂移量的增大而增大、也随磁偏角观测值的增大而增大 ,该结果对指导台站提高该仪器磁偏角观测值的精度有一定意义。
This paper studied the observation error of declination with bias current by FHD 1 proton precession magnetometer in theory. The result indicates that the error is increased with the value of declination and bias current drift, which has s significance to improve the precision of declination observation by that magnetometer at stations.
