摘要
以肥乡地震台地电场资料为基础,对观测中常见的一些干扰和典型变化形态进行详细识别和归类,认为主要存在地电暴干扰、高压直流输电干扰、人为干扰和电极引线漏电干扰。通过对数据异常案例研究分析,当出现干扰时,认为应该遵循"逐步逼近法"和"替换法"原则。
On the basis of Feixiang electric field and typical change forms are identified, and the seismic data, the observation interference and the common main interferences are electric storm, high voltage DC trans- mission, human disturbance and electrode wire leakage. Through the data exception case are analyzed, when interference occurs, the principle of ＂step-by-step approach＂ and ＂substitution method＂ should be followed.
