| 摘 要： | 地磁日变基值的选取是海洋磁力测量地磁日变改正的重要内容。本文分析了地磁日变基值对磁测的影响,通过实例进一步说明了合理选择地磁日变基值的重要性。结论表明:单站地磁日变改正时,为了消除日变基值偏差对磁测的影响,同一测区不同航次测量,应当选择统一的日变基值。

| Abstract: | The selection of base value is critical to the geomagnetic diurnal variation correction in marine magnetic survey.The influence of base value on the survey has been analyzed in this paper,and the significance of the proper base value has been testified with an example survey that are completed by two or more voyages and with a base station.The conclusion shows that the base value of different voyage must be the same to eliminate the influence caused by the difference between the base values. |
