嘉峪关地磁台墩差测量与仪器比测
|
摘要
墩差测量和仪器比测是地磁观测中最基本的工作,直接影响到观测资料的质量和使用价值。近年的研究结果表明,震磁异常通常为几nT至几十nT。因此,提高观测数据的准确性对地磁预报地震具有深远意义。对嘉峪关地磁台仪器比测和墩差测量的方法及结果作了简要总结,供兄弟台站借鉴(文中所用的比测数据和墩差测量数据是北京台传递的标准结果)。
The pilar difference measurement and instrument comparison is basic to the quality and usage of the recorded geomagnetic data.According to the research result of recent years,the seismic geomagnetism abnormality is usually from several nT to tens of nT.Therefore,the accuracy of the recorded geomagnetic data is really important for earthquake prediction.ln this paper,we introduce the method and result of the pilar difference measurement and instrument comparison in Jiayuguan station,and it could be helpful for other seismostations.
