| 摘 要： | 为了消除或减小地磁日变化对海洋磁力测量的影响,提出采用同步比对法和相关分析法计算两日变站间地磁日变化的时差。分析表明:同步比对法和相关分析法得到的时差更能真实反映两站间的时间变化,建议在海洋磁力测量多站地磁日变改正时差计算中采用。 |
| 关 键 词： | 海洋磁力测量 地磁日变改正 时差改正 同步比对法 相关分析法 |

| Abstract: | To eliminate or diminish the influence of geomagnetic diurnal variation on marine magnetic surveys, the synchronous comparison method and correlation analysis method have been adopted to calculate time difference between two diurnal variation stations. The conclusions show that time difference obtained by the above methods can reflect actual time difference between two stations. It is suggested that the methods should be applied to time difference calculation for the multi-station diurnal variation correction in marine magnetic surveys. |
| Keywords: | marine magnetic survey geomagnetic diurnal variation correction time difference synchronous comparison method correlation analysis method |
