随着温度的升高和氢分压的增加，保温时间缩短。在主还原期（还原率为10 ~ 90%），界面反应符合公式{1-（1-R）1/3}=Kt，活化能为18.4kcal/mol。通过无因次时间分析，发现在还原末期，气体通过产物层的扩散作用增加。还原速率与氢分压呈线性关系，在裂解氨气中的反应速率比氢氩混合气中的反应速率慢。此外，实验结果与Eyring理论符合得很好。（1971年7月8日）
The incubation time was shortened with increase in temperature and partial pressure of hydrogen. In the main reduction period ranging about 10 to 90% reduction, the formula of interface reaction {1-(1-R)1/3}=Kt was valid, and the activation energy was 18.4kcal/mol_ According to the dimensionless time analysis, the effect of gas diffusion through the product layer was found to be added in the final period. A linear relation was obtained between reduction rate and partial pressure of hydrogen, and a slower reaction rate than in the mixture of hydrogen and argon was found in cracked ammonia gas. Furthermore, the experimental results were in good agreement with the Eyring theory. (Received July 8, 1971)
