| 摘 要： | 为提高海底管线探测的效率，从磁偶极子模型出发，通过磁矩的轴向分解及其磁场的矢量合成，并考虑地磁背景场影响，提出了一种计算水下管线磁场的数学模型，通过仿真计算三种不同走向管线的磁场分布并与实测数据比对，证明所建模型是正确的。

| Abstract: | In order to detect underwater pipeline effectively,based on magnetic dipole model,the article presents a method for calculating magnetic field of underwater pipeline by separating a magnetic moment into three components in direction of coordinate-axis,and combining the field vectors meanwhile considering the earth's magnetic background influences.It is proved true by comparing simulated three different directional pipelines magnetic fields with actually surveyed results. |
