摘要
讨论了海洋船舶腐蚀引起的静电场的基本模型,对GalvanicSystem电场在水中兵器、电场测量体等实体附近可能产生的电场畸变进行了分析计算.理论计算表明:雷体等水下实体对电场的扰动的大小主要取决于雷体与舰船的距离、雷体材料的电阻率、雷体的尺寸.当距离大于10m时,其引起的电场畸变的相对变化率小于2%,由此得出了利用舰船电场远场作为启动信号时可以不考虑电场扰动的结论.
The basic model of the electrostatic field caused by marine corrosion is discussed. The quantitative analysis and computation of electric field distortion induced by underwater object such as mines is carried out. It is shown that the influence is related to the distance, material resistivity and volume of object. When the distance is over 10 m, the relative rate of change of electric field distortion is less than 2%.
