| 摘 要： | 根据程序升温还原反应的实验曲线所满足的边界条件,构造了D-M分布函数,借以描述峰高与温度之间的定量关系.经理论推导发现,在计算固体氧化物还原反应动力学参数时,D-M分布函数可在易获取实验数据的前提下,合理地进行还原反应进程α的求值,并能化简线性升温条件下的微分方程.文中结合实例,对建立D-M分布函数及其计算还原反应动力学参数方面的应用做了进一步的阐述.

| Abstract: | On the basis of the boundary condition which is satisfied by the experimental curve of TPR, D-M distribution function is formulated to describe the quantitative relation between the height of curve H and the temperature T. In the calculation of kinetic parameters of reduction reaction for oxide solid, the fraction reduced a can be easily evaluated. Differential equation for the condition of linear increasing temperature can be simplified by using D-M distribution function. By taking the reduction of copper oxide as an example, the formulation of D-M distribution function and the application of it to the calculation of reduction reaction kinetic parameters are further described. |
