提出了一种在金属熔体中使用的新型长寿命氧传感器；利用氧浓差电池的可逆性，在测试间隙对氧电池施加大小适当的补偿电流，可消除或减小参比电极的极化，使普通氧传感器的使用寿命延长１０倍以上；推导了补偿电流密度的计算公式，并得到了验证
A new type of long-life oxygen sensor used in metal melt is proposed. By using the reversibility of oxygen concentration cell, an appropriate compensation current is applied to the oxygen cell in the test gap to eliminate or reduce the polarization of the reference electrode , To extend the service life of ordinary oxygen sensor more than 10 times; derive the calculation formula of compensation current density, and has been verified
