摘　　要：测量了液氮温区导电聚吡咯薄膜(σ=100s/cm,8s/cm)在直流电场下的电阻,发现电阻对电场有依赖关系。所有的结果在变程跳跃理论下得到很好的解释。The resistance of conducting polypyrrole films (σ=100s/cm, 8s/cm) under de electric field was measured in the liquid nitrogen temperature range. It is found that the resistance is electric field depended. All results can be well interpreted with variable range hopping theory.
