摘　　要：研究了氧化锆氧传感器在700℃和SO_2气氛中较长时间内电导率的变化情况。实验表明,其电解质总电导率和电极电导率增大,而且电极电导率与温度的关系不再符合Arrhenius公式。此外.还研究了氧化锆氧浓差电池的电动势受SO_2影响的情况,有SO_2存在时,氧浓差电池的电动势增大,但电动势与氧分压的关系不再符合Nernst公式。The influence of SO₂on the conductivity of zirconia oxygen sensor at 700℃ was studied. The experimental results show that the total conductivity of solid electrolyte and the electrode conductivity increase in the presence of SO₂ but the Arrhenius relation of the electrode conductivity no donger holds. In addition, the influence of SO₂ on the EMF of zirconia oxygen sensor was also investigated. In the presence of SO₂, the EMF of the oxygen concentration cell increases, but the relation between EMF and oxygen partial pressure is not in accordance with the Nernst equation.
