摘　　要：介绍了一种来源于弱电鱼的仿生主动电场探测机制,为了优化主动电场探测方法,研究了勘探地球物理学中激发极化法的应用,认为在同样的激发条件下,水下被测物也一样存在这种激电过程。搭建实验平台环境,使用小型蓄水池模拟海水域环境,辅以成熟的仪器设备,在实验平台中分别进行直流激电法与变频激电法电场探测实验。在2个不同的实验中,分别设定了不同的特征关系式对实验结果进行量化分析,每个实验分别对空白背景对照组、铜立方体、铜圆柱、铝立方体、铝圆柱与塑料圆柱体进行测试,直流激电法原理简单、还原度高,所有实验组与空白背景环境存在明显差异,且所有金属物体的激电效应都强于非金属塑料,符合理论分析。变频激电法实验相比于直流激电法没有那么明显的组间关联性与规律。A bionic active electric field detection mechanism derived from weak electric fish is introduced.In order to optimize the active electric field detection method,the application of induced polarization method in exploration geophysics is studied.It is considered that underwater measured objects also have this induced polarization process under the same excitation conditions.An experimental platform environment is set up and a small reservoir is used to simulate the sea water environment,and then a mature equipment is used to conduct electric field detection experiments by DC induced polarization method and frequency conversion induced polarization method respectively.In two different experiments,different characteristic relationships are set up to quantify the experimental results.In each experiment,the blank background control group,copper cube,copper cylinder,aluminum cube,aluminum cylinder and plastic cylinder are tested respectively.The principle of DC induced polarization method is simple and the reduction degree is high.There are obvious differences between all experimental groups and blank background environment,and the induced polarization effect of all metal objects is stronger than that of non-metallic plastics,which is in line with theoretical analysis.Compared with the DC induced polarization method,the frequency conversion induced polarization experiment has no obvious correlation and law between groups.
