摘    要：用新方法测定了不同温度下CO还原ZnO生成Zn蒸气和CO₂的反应的平衡常数， 得到了该反应的lgK_p=-10 630/ T ＋6.92关系式。 将此式与文献报道的关系式进行比较， 在1 250 K时， K_p最小值为0.012 4， 比本研究低0.013 6； K_p 最大值为0.032 4， 比本研究高0.006 4； 其余的K_p值与本研究的结果比较接近， 差值不超过0.005， 说明本研究结果是可靠的。

Abstract: Equilibrium costant of the reaction of CO deoxidizing zinc oxide and generating gaseous zinc and CO₂ was measured in new method at many temperatures.The equation Lg K_p =-10 630/ T ＋6.92 was obtained and the calculated result was compared with that of the equations in many documents. At 1 250K, the smallest K_p of the equations in many documents is 0.012 4 and 0.013 6 below that of this study, the largest K_p is 0.032 6 and 0.006 4 greater than that of this study, the others are close to that of this study. The differences between the others and this study are smaler than 0.005, it is thus proved that the result of this study is reliable.
