摘要
根据昌黎地震台3年多的实际观测资料,对208#CTM-DI磁通门经纬仪的稳定性进行了初步分析,结果显示:仪器格值标定和稳定性良好,但零场漂移S0较大,应予调整。反映磁通门探头磁轴不重合度的水平角度δ和垂直角度ε总体较稳定。
Based on geomagnetic data recorded in Changli Seismic Station for three years,the stability of 208# CTM-DI geomagnetic thexdolite was analyzed. It was found that the stability of the instrument was all right,but its zeroth field excursion was on the high side,should be adjusted. The aclinic angle and upright angle about the magnetic axis and the photic axis was steady as a whole.
