摘　　要：针对氧敏材料氧化锆氧浓差电势受工作温度及本底电势影响很大的特性,设计并制作了氧化锆氧传感器浓差电势的测量和检测系统,重点实现了不同工作温度的精确、稳定及迅速测量。在此基础上,完成了温度从400℃到800℃、氧气浓度从0%到6%时,氧化锆传感器浓差电势的测量的试验。对试验数据进行作图比较、回归分析等并得出结论。This paper designed potential of zirconia oxygen sensor influences a lot by working temperature and background potential.Designed and produced two systems to measure and detect it.Different from the traditional way,the systems realized that the working temperature was more precise,stable and response quickly.Based on these,it completed the zirconia sensor concentration potential measurement experiment with temperature from 400 ℃ to 800 ℃ and oxygen content from 0% to 6%.Mapping comparison and,regression analysis were adapted to the experimental data to draw a conclusion.
