摘　　要：提出一种测量舰船电场的新方法,即用二次谐波方法测量大轴周围磁场,从而确定大轴电流,进而分析由大轴电流带来的舰船电场.理论和实验均表明,该方法结构简单,构思精巧,是检测舰船电场的方法之一.In this paper, a new method to measure the naval electric field is put forward. This method consists in measuring the magnetic field around the axis by second-harmonic generation, thereby the current of axis can be got, and the naval electric field measured by the second harmonic generation is analysed. The theory and experiment show that this method is of simple structure and precious design. It is one of the methods to measure the naval electric field.
