摘　　要：海水中电场测量体会对目标电场产生影响,为了提高电场测量的准确度,利用有限元分析的方法研究了物体对海水电场分布的影响因素,并确定畸变电场的分布规律。仿真结果表明:海水电场畸变峰值大小及其畸变区域受物体的电导率及其形状影响,物体电导率小于或大于海水电导率时对电场分布的影响截然相反,物体形状的曲率越大,电场畸变的峰值越大,但畸变区域越小。Electric field measurements in seawater will affect the target electric field.In order to improve the accuracy of the electric field measurement,the influence factors of the object on distribution of the electric field in seawater were studied by the finite element method,and the distribution law of the distortion electric field was determined.The simulation results show that the magnitude of the distortion peak and the distortion area are affected by the conductivity and shape of the object.When the conductivity of the object is smaller or larger than that of the seawater,the effect on the electric field distribution is on the opposite:the larger the curvature of the object is,but the larger the peak value of the distortion is,but the smaller the distortion area is.
