| 摘 要： | 本文主要利用锦州义县地震站＂十五＂观测以来的地电场分钟值资料,对观测中常见的干扰因素进行了详细的识别与归类,并对干扰特征和判别原理进行了分析与探讨。研究结果表明：在地电场观测过程中存在地电阻率同场观测干扰、磁暴干扰、雷电干扰、降雨干扰、游散电流变化干扰、电极不稳定引起的数据漂移及观测系统变化干扰、仪器死机、重启仪器造成数据丢失干扰等。

| Abstract: | Based on the geoelectric field minute value data of the Jinzhou Yixian Seismic Station since the 10th five-year plan,this paper analyzed the identification and classification of the common interference factors in seismological observation.The interference features and the discrimination principles are also introduced.The results showed that there were many interference factors in the geoelectric field observation,such as the earth resistivity observation at the same field,geomagnetic storm,lightening,rainfa... |
