本文从岩石和矿物电阻率的一般规律出发,导出岩石和矿物电阻率相对变化与湿度的近似关系,并试图应用它来解释视电阻率脉冲现象和地震的关系,同时讨论了ρ_s脉冲作为临震突跳异常的可能性,并得到几次震例的证实,为利用视电阻率脉冲作临震预报提供了某些依据。 Based on the general laws of resistivity of rock and mineral, this paper derives the approximate relationship between the relative change of resistivity of rock and mineral and the humidity, and attempts to explain the relationship between apparent resistivity pulse and earthquakes. At the same time, The possibility of sudden jump anomalies is confirmed by several earthquakes and provides some basis for the use of apparent resistivity impulses for earthquake prediction.
