| 摘 要： | 阐述了海水中舰船极低频电场的产生机理,并利用船模在实验室实际测量了腐蚀电流和外加防腐电流经螺旋桨转动的调制后在海水中产生的极低频电场.测量结果表明,由不同金属制成的船壳和螺旋桨之间的腐蚀电流和防腐电流经螺旋桨转动的调制后,在海水中会产生以螺旋桨转动频率为基频以及高达几百赫兹的谐波的极低频电场,成为舰船的一个重要目标特性. |

| Abstract: | The source mechanism of ELFEF of ship is explained in this paper, and the ELFEF of ship model caused by the corrosion current and the impressed current modulated by shaft's rotation in sea water is measured at laboratory. Results show that both the shaft-rate modulated currents will generate an ELFEF which contains both the shaft fundamental and harmonics extending to several hundred Hz and becomes an important target characteristic of ship. |
| Keywords: | ship engineering ELFEF corrosion current ICCP |
