| 摘 要： | 海面磁场等值线图是海洋磁探测的最基本图件，从中可以确定水下铁磁体的位置所在。为研究水下铁磁体的海面等值线图特征，将铁磁体磁矩分解为水平磁矩与垂直磁矩，分别求出各自的海面磁场计算公式，然后进行合成得到水下铁磁体海面磁场的计算公式? |
| 关 键 词： | 海洋磁力测量 铁磁体 磁矩 海面磁场 等值线图 |

| Abstract: | The contour of sea surface magnetic field is an essential map in marine magnetic survey.By using this map,the position of underwater ferromagnet is easily defined.In order to find out the characteristic of this contour,the magnetic moment of underwater ferromagnet is separated into two parts by horizontal and vertical direction,and then a set of formulae is deduced respectively for each direction.Finally,a composed formula is formed for calculationg the total sea-surface magnetic field of underwater ferromagnet. |
| Keywords: | marine magnetic survey ferromagnet magnetic moment sea surface magnetic field contour |
