摘要

应用地电学的差分能量法 ,对高邮台地电阻率日均值进行处理分析。结果表明 ,差分能量法对抑制较长周期变化、突出异常信息十分有效 ,特别对突升、突降急剧变化的短临异常有着明显的指标反应。这可能反映了地壳介质应力变化过程中较高频的扰动。在观测系统和观测环境正常的情况下 ,若用差分能量法处理的 ρs 日均值出现一阶差分能量的对数大于零 ,应视为震兆异常。
The daily mean of the ground resistivity of Gaoyou station is processed by the method of differential energy of geoelectricity.The results show that the method is useful to restrain the variation of more long cycle and protrude anomalous information,especially can obviously reflect the short-impending anomaly such as sharp rise, sharp decline which may be the response to the disturbance of high frequency in the varying course of crustal medium stress.It should be thought of the precursor anomaly if the logarithm of the first difference of energy is larger than zero when the daily mean of ρ s is processed by the differential energy.
