中文摘要：

本文主要利用榆树地震台2000年以来的地电场资料，对观测中常见的干扰因素进行了详细的识别与归类。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、雷电干扰、地电暴干扰、电极长期稳定性问题引起的数据漂移及数据传输错误等。

英文摘要：

In this paper, the common interferences in the geoelectric data observed by Yushu seismostation since 2000 are identified and classified. The results indicated that there are some interferences in geoelectric field observation. For example, the interference of observation meanwhile by terrestrial resistivity, the interferences of thunderbolt and geoelectric storm. There are drift of data attribute the cause to questions of chronic stability for electrode , and the error of data transmit, and so on.
