摘要
地电观测由测量区、外线路和观测仪器及辅助设备组成。观测系统容易受到外界干扰,而且故障较多,笔者根据多年的实践经验,对常见的干扰及故障现象进行了分析研究。结果表明:地电观测对区域的观测环境变化以及细微电磁环境和观测系统的变化都有非常灵敏的反应。
The terrestrial electricity observation is composed of the survey area, outside the line and the off-carriage instrument and the supporting facilities. The observation system is .easy to receive the external interference, and easy in troubles. According to the experience obtained for many years, the common interferences and troubles are analyzed and studied. The result indicated that the terrestrial electricity observation is sensitive to the variation of region observation environment as well as the slight change of the electromagnetic environment and the observation system.
