摘要	液态铅铋合金氧测控作为加速器驱动次临界系统（ADS）的关键技术之一，对抑制结构材料腐蚀具有重要作用。为深入开展氧测控技术研究，自主研制液态铅铋氧测量及控制实验装置，并基于该装置开展Pt／Air型氧传感器在饱和氧浓度下的稳定性与精确性测试实验。结果显示，在625～786K温度范围内，Pt／Air型氧传感器电压信号经过传热产生的弛豫（〈750s）之后稳定性表现良好，测量值的最大绝对偏差为10mV，最大相对偏差为1．5％，与理论值符合较好，其偏差主要来自热电压及氧化物的影响。
其他摘要	Measurement and control of oxygen content in liquid lead-bismuth is one of the key technologies in accelerator-driven subcritical system （ADS）. It plays a vital role to resist structural material corrosion. Liquid lead-bismuth oxygen measurement and control experimental device was designed and constructed independently to study the key technology. Pt/Air reference electrode oxygen sensors were tested for the stability and veracity in the saturated oxygen concentration with the device. The results showed that in the temperature ranging from 625 ~ 786 K, it performed good stability after relaxation time less than 750 s for thermal equilibrium relaxation affect by the low heat conduction of YSZ ceramic tube. The voltage signal of Pt/Air sensor was in good agreement with the theoretical value, with absolute deviation less than 10 mV and relative deviation less than 1.5~. Reason for deviation came from thermoelectric voltages and oxide impurities.
