【摘要】 张家口地震中心台经过多次试验 ,成功研制了大地电场铅电极 ,采用新型的电极孔成孔方法及埋设技术进行了试验观测 ,从实验数据中可以明显看到地电场的日变形态。该电极具有制作工艺合理、电极差较小、稳定性能较好、噪声低、使用寿命长、易于保存和使用方便等特点 ,不仅可以满足大地电场长期定点观测的要求 ,还可以用于地电阻率观测 ,亦可作为地震电磁扰动观测中的电极传感器。铅电极应用前景广阔。更多还原

【Abstract】 The earthquake centre of Zhangjiakou has succeeded to research of the lead electrode for earth electric field and test several times. The new making electrode hole method and bury technique are adopted. The daily variation of electric field can obviously record in the experimental data. This electrode is reasonable in technology,stability,low noise, long life,easy to maintain and use. This electrode can not only be used to the resistivity of ground observation and also satisfied to the request of earth electric field observation in fixed position for a long time. It can also be used as electrode sensor of earthquake electromagnetic disturbance. It has a bright future.更多还原
