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.
According to the boundary conditions of the experimental curve of programmed temperature-programmed reduction reaction, the DM distribution function is constructed to describe the quantitative relationship between peak height and temperature. The theoretical derivation shows that in calculating the kinetic parameters of solid oxide reduction reaction, DM The distribution function can reasonably estimate the α of the reduction reaction under the premise of easy access to the experimental data, and can simplify the differential equation under the condition of linear temperature rising.In this paper, we establish the DM distribution function and the calculation of the reduction reaction kinetics The application of learning parameters has been further elaborated.
