为探索潜艇处于复杂水域时水下标量电位的分布，将海床倾斜水域作为切入点，在利用镜像法推导出海床倾斜水域潜艇水下标量电位的分布表达式后，对水下电位的分布特征进行仿真分析，并与传统平行分层环境下电位分布进行对比。研究表明：海床倾斜水域潜艇水下电位分布特征明显，量值可观，可用于潜艇的探测与定位；小角度范围内，改变海床倾斜角度和海水电导率，所研究水域电位分布特征的区域性不变，其量值随海床倾斜角度增大呈线性增加，随海水电导率增大呈非线性衰减；相比于平行海床水域，海床倾斜时不存在电位为0的场点，且沿偶极矩方向的对称性丧失。研究结果为进一步研究更为复杂水域潜艇腐蚀相关电场的场分布问题奠定了基础。
In order to explore the distribution of underwater electric scalar potential produced by a submarine in complex waters, inclined seabed waters was taken as a breakthrough point, after the expressions for UEP in there was derived by using mirror image method, the numerical simulation method had been used to analyze the characteristics, and compare to the parallel seabed waters. The results show that:the UEP is suitable for submarine detection and position fixing because of its measureable magnitude and obvious distribution characteristic; in a small angel range, the inclined angle of seabed and the electrical conductivity of seawater will produce an effect on the value of UEP but not the regional characteristics, the value increases linearly with the increase of the inclined angle, degenerates quadratically with the increase of electrical conductivity; there is no zero potential point and symmetry along the direction of the dipole moment when the seabed is tilted. The results lay a foundation for further researching on the distribution of corrosion related electric field produced by a submarine in more complex waters.
