摘　　要：用钢箔称重法在温度为 4 95、5 0 0和 5 1 5℃时对氨分解率与氮势的关系进行了研究 ,实验结果表明 :在温度一定时 ,随着氨分解率的降低气氛的氮势反而升高 ;当氨分解率一定时 ,随着温度的升高 ,气氛的氮势也随之升高 .In this paper, the weight gain method was used for the study of the relationship between the decomposition rate of ammonia and nitrogen potential at 495, 500 and 515 ℃. The experiment results demonstrated that the decomposition rate of ammonia decrease with the increase of the nitrogen potential when temperature is constant; the nitrogen potential rise with the increase of the temperature when the decomposition rate of ammonia is constant.
