摘要
讨论分析了3种地电阻率年变畸变异常,即年变幅度增大型、年变幅度减小型、年变畸变混合型。并针对不同的异常给出了相关分析方法,为识别和使用这类异常提供了一定的思路和科学依据。
In this paper, three types of distortion anomalies in annual variation of earth resistivity are discussed and analyzed, which are ① the type of amplitude increase in annual variation; ② The type of amplitude reduction in annual variation; And ③ combining distortion of annual variation. As for different types, related analysis method are presented, which provides some thoughts and scientific basis for future distinguishing and using of these anomalies.
