摘要
在均匀土壤中，将电位极置于零电位区，接地电阻的测量值偏小７％，但在双层土壤中，仍将电位极置于零电位区，接地电阻的测量值可能偏小３０％以上，此时应该采用补偿法进行测量。
? Experiments show that,in even soils,the measured values of the ground resistance are 7% lower than usual when the potential probe is placed in the zero potential region.But in case of two-layer soils,the values of the same may be lower as much as over 30% than usual,so the compensating method must be applied during measurement.
