| 摘 要： | 在分析地电场测量电极的极化电位产生机理的基础上，通过同类电极组合试验和不同类电极对比试验，对极化电位在地电场观测中的影响形成几点认识：①由于电极和土壤介质之间的接触电位和扩散电位的影响，极化电位的存在具有普遍性；②当工作状态稳定后，电极极化电位可能使得观测结果产生固定偏差，但在误差允许的范围内；③正常情况下，电极极化电位的存在不影响对地电场变化特性的观测。

| Abstract: | In the paper, based on the analysis of polarization potential formation mechanism of geoelectric field measure electrode, with combination experiment of same types electrode and comparison experiment of different types electrode, some opinions are put forward about the influence of polarization potential in measuring geoelectric field： （1） Due to the influence of contact potential and diffusion potential between electrode and soil, polarization potential is common exist; （2） polarization potential of electrode will brings fixed error in working steady state, and this error is within the allow range of geoelectric field observation; （3） at normal condition, polarization potential of electrode doesn＇t influence the observation to characteristic of geoelectric field. |
