根据潜艇水下腐蚀相关电磁信号的产生机理，该文提出可采用由电偶极子首尾相接而成的电流线对其进行模拟。分别采用边界元建模及电流线建模方法对潜艇模型的水下静态电场进行计算，对比分析结果表明，将电流线作为对潜艇水下腐蚀相关静态电磁信号进行估算的数学模型是可行的。在此基础上，结合分层导电媒质中水平直流电偶极子的磁场表达式，对潜艇腐蚀相关静态磁场在全空间中的分布特征进行了仿真分析。结果表明，空气中潜艇腐蚀相关静态磁场近场量值可测，分布特征明显，可用于航空探潜；海水中潜艇腐蚀相关静态磁场远场按距离的平方反比衰减，可用于消磁潜艇的远程探测。分析所得典型结论为进一步的应用研究奠定了基础。

According to the generation mechanism of the underwater corrosion-relative-electromagnetic field of submarine, a current-line which is regarded as end-to-end electric dipole is proposed to simulate the field distribution. Firstly, the underwater static electric field of a submarine model is calculated respectively by the boundary-element method and the current-line method, and the contrastive analysis of the calculation results shows it is feasible that the current-line mode is selected to estimate the underwater corrosion-relative- electromagnetic field of submarine. Then, based on the magnetic field expressions of the horizontal static electric dipole in layered-conductive media, the static corrosion-relative-magnetic field distribution of the submarine in all the space is simulated and analyzed. The simulation results show that, the near-field of the magnetic field in air is suitable to be as a new target of the aerial submarine hunting because of its measurable magnitude and obvious distribution characteristic, as well as the far-field is suitable to be as signal source for remote detection or position fixing of the degaussing submarine because it degenerates with the inverse square of the distance. The typical research results lay the foundation for the further application research.
