| 摘 要： | 地磁场中的金属壳体潜艇在航行时会产生感应电动势,从而产生感应静电场,将潜艇简化为长椭球壳,分别建立了潜艇处于浮航和潜航两种状态下的运动感应静电场模型,给出了电场三分量表达式;以美海国军洛杉矶级潜艇为例进行了感应电场的仿真计算,获得了两种状态下潜艇水下电场分布,仿真结果表明:感应电场在潜艇附近量值较大,随距离衰减明显。

| Abstract: | A submarine with metal hull can induces static electric field when it moves across geomagnetic field .A submarine can be treated simply as a metal spheroid hull with long macroaxis and considering submarine in two conditions：moving on surface and diving,the induced static electric field model was deduced.Taking one USN nuke submarine as an example,the distribution of its induced electric field is simulated by computers conveniently to obtain two kinds of underwater electric field distribution.Results show that,the magnitude of induced electric field near the submarine is large with apparent characteristics of range attenuation. |
