摘要

按国家地震局编制的《地磁台站观测规范》规定,地磁台仪器震每5年比测一次,自1989年起全面系统地、有计划有步骤地开展了三分量地磁仪器的比较工作。到目前为止,已完成全国36个地磁台中的33个台的仪器比测和13个台的天文方位角复测,取得了一批有价值的数据,同时协助台站解决了一些具体技术问题,促进了台站的正常化、标准化。
According to the stipulation of "Observation Standards of Geomagnetic Observatories" estab- lished by the State Seismological Bureau, instruments used in the geomagnetic observatories must be compared once every five years. The comparison work for the three-component geomagnetometors have been carried out step by step since 1989. Until now, the instrument comparison observations for 33 observatories and reobservations of astronomical azimuth for 13 observatories out of the total 36 geomagnetic observatories in China have been completed, gaining some valuable data. At the same time, some specific technical problems in the observatoris have been solved with the help of the techni- cal personnel in the group of comparison observations, thus promoting the normalization and standar- dization of the observatories.
