【摘要】 本文分别研究了ＺｒＯ_２（ＭｇＯ）固体电解质管头壁厚、参比电极量对定氧测头响应时间的影响，得出了以ＺｒＯ_２管头壁厚为０．６０～０．８０ｍｍ，Ｃｒ／Ｃｒ_２Ｏ_３参比电极加入量为４０～６０ｍｇ所组成的定氧测头响应速度最快．同时采用了“双偶法”对定氧测头在工作过程中的热平衡态进行了研究．结果表明：氧浓差电池中的传热是响应过程的控速步骤，氧电势曲线上峰值的产生是起源于电池中的热平衡态．更多还原

【Abstract】 Effects of the tip end thickness of ZrO2(MgO) tube and the amount of reference electrode addition on the response time were investigated in this paper. It is concluded that the optimized parameters for tip thickness of ZrO2 (MgO) tube and the amount of reference electrode are 0.60～0.80mm and 40～60mg respectively. The thermal equilibrium of response process for oxygen probe using"Two TC Method" was also investigated. The results show that the heat transfer in the oxygen galvanic cell is the limitting-step in the response process and the peak appeared in the EMF curve is resulted from the thermal equilibrium in the oxygen galvanic cell.更多还原
