摘　　要：利用液态金属汞,测量了304不锈钢不同电位下表面膜的电子导电性能,发现不锈钢表面膜的电子导电性能相当好,膜电子电阻很小这一与文献不同的实验结果,并浅析了不同电位区表面膜电子电阻的差异。Electronic resistance of surface film on 304 stainless steel was measured in liquid Hg. Results show that the electronic conductivity of surface film is considerably high, which is quite different from some published results. The difference of the electronic conductivities in different potential ranges was also briefly discussed.
