摘要
地磁观测是地震前兆观测的基本项目之一,观测资料的质量高低直接影响到地震预报的准确率。各个观测台站在观测过程中仪器是否受到干扰要做认真准确的分析,这样才能保证资料的可靠性。溧阳地震台从新台址启用后,观测人员发现观测数据的精度与其它台有一定的差距,为此,我们对影响地磁观测的各种因素进行了分析,并逐项进行排除,最终使溧阳台的地磁观测资料由不可用,变为精度较高,稳定性很好,从而使地磁观测资料质量得到保证。
The geomagnetic measurement is one of basic precursory observations. Its observation quality will affect the correctness of the earthquake prediction. The cognizing correctly several interference factors in seismic stations are basic work for good quality of geomagnetic observation data. After the new seismic station was put into opera- tion, the precise of geomagnetic observation data were lower than that of other seismic stations. In order to increase the precise of geomagnetic observation data, we analyze the several factors affecting the precise of data and take rel- ative measurements to ensure the stable observation environment. At end the data precise is increased.
