摘　　要：拟用科学方法确定主动电场探头电极最优分布方式。通过试验设计的方法确定结构参数,并运用有限元软件进行仿真,利用电场不均匀系数作为评价指标,找出均匀性最优的探头结构,确定最优探头结构下各电极之间距离的关系。结果表明,当发射电极与接收正电极之间距离(B)与两发射电极之间距离(A)之比为1∶2且接收电极之间距离(C)与发射电极之间距离(A)呈C=0.02A^2-2.5A+132二次函数关系时形成的主动电场均匀性最好,探测效果最佳。本研究为主动电场探头设计提供了理论依据。The purpose of this study is to determine the optimal distribution of electrolocation probe electrodes by scientific methods. The structural parameters are determined by the method of experimental design and simulated by finite element software. Using the electric field non-uniformity coefficient as the evaluation index to find the optimum probe structure, and the relationship between the distances of the electrodes under the optimum probe structure is determined. The results show that when the ratio of the distance between the emitter electrode(B) and the receiver electrode to the distance between the emitter electrode and the emitter electrode(A) is 1∶2 and the distance between receiving electrodes(C) and transmitting electrodes(A) is C=0.02 A^2-2.5 A+132, the uniformity of electrolocation is the best and the detection effect is the best. This study provides a theoretical basis for the design of electrolocation probe.
