| 摘 要： | 本文通过河北省隆尧县大柏舍地电台不同供电极距试验观测资料,与地下潜水水位动态的相关分析及数学模型计算结果,给出地电阻率年变化的一种物理解释,即认为大柏舍台地电阻率年变化是由于供电极距短,勘探深度浅,从而受潜水动态影响的结果。为消除大柏舍台地电阻率年变化,应采用不小于1500米的供电装置。

| Abstract: | Through corelation analysis and mathematical model computation of the observed data of earth resistivity with different electrode spacing carried out at Daboshe Station, Longyao County of Hebei province, a physical explanation of the annual variation of earth resistivity is proposed. It is highly probable that the annual variation of earth resistivity is caused by the effect of change in ground water level resulting from the close electrode spacing used. To avoid such interference, the electrodes should be spaced at least 500 meters from one another (the overall dimension should be at least 1500 meters) at Daboshe Station. |
