Research on a type of Pb-PbCl_2 non-polarizable electrode

在分析不极化电极基本实现原理的基础上,研究和讨论影响地电场测量电极工作稳定性的主要技术因素,采用Pb-PbCl_2技术方案和可螺旋拆解的分体式结构,完成一种不极化电极的研究和试验。结果表明:①该电极的主要技术性能不低于目前国内外在该领域的指标要求;②在性能试验期间,极化电位的一致性和稳定性均较高;③应用研究过程中,较好记录了地电场日变化和地电暴等背景变化。

In this paper, based on the fundamental principle of non-polarizable electrode, the mainly technical elements that caused electrode performance instability during the geo-electric field observation are analyzed and discussed firstly. And then, according to these elements, a type of Pb-PbCl2 non-polarizable electrode using a kind of combined structure connected by spiral are studied, developed and tested. The results indicate that： ①the mainly technical performances of this type of electrode are archived the best level in currently;②the consistency and stability of the polarization potential are much high during the test period;③the telluric changes, such as the daily variation of the geo-electric field, the electrical storms and etc. , are observed perfectly in the application process.
