| 摘 要： | 测量引线间互感可能造成土壤电阻率的测量误差。计算了引线间互感对土壤电阻率测量的影响。结果表明 ,当均匀土壤电阻率或多层土壤中下层土壤电阻率较低时 ,引线间互感可能造成较大的测量误差 ;采用短电压极距的不等极距四极法 ,不能消除互感造成的测量误差

| Abstract: | When the resistivity of a uniform soil or the bottom layer resistivity of a multilayer soil is low, the measurement error caused by the inductive coupling is large. A short potential probe distance can not be used to exclude the effect of inductive coupling. The error of soil resistivity measurement may be produced by the inductive coupling between current and potential leads. The influence of inductive coupling has been calculated. |
