摘　　要：潜艇空间磁场分布规律是磁性防护的基础,在磁偶极子等效的基础上,对潜艇磁偶极子等效的变迁规律进行了分析,提出了潜艇远场磁场分布的全空间一致性。实验结果验证了潜艇磁场等效变迁规律的正确性,表明潜艇整个空间的远场磁场可以用同一个磁偶极子的磁场等效,为潜艇空间磁场的深入分析和高空磁性评估与防护奠定了基础。The spatial magnetic field distributing role of submarine is the base of magnetic defense. Based on the magnetic dipole equivalent theory, the changing role of magnetic dipole equivalent for submarine is analyzed, and the distributing coherence of far field in all space for submarine is proposed. The result of experiment validated the correctness of the changing role of magnetic dipole equivalent for submarine, and showed that the far field of submarine in all space can be represented by the field of one single magnetic dipole, which settled base for the further analysis of spatial field and aerial magnetic evaluation and defense for submarine.
