摘　　要：在层状扩散模型的基础上,以1萘酚与对氨基苯磺酸重氮盐在旋转填充床内发生的竞争串联偶氮化合反应为例,探讨了填充床内的微观混合情况.引进了两个调整反应物与生成物关系的参数,对整个反应过程建立了一个计算数学模型;并进行了计算,计算预测的结果与实验数据在规律上和数值上都较好符合.Based on the laminar diffusion model, the micro-mixing in a rotating packed bed （RPB） was discussed by taking the competitive and consecutive azobenzene reaction between 1-naphthol and diazotised sulphamilic acid as reaction system. A mathematical model was presented to describe the whole process of the reaction by introducing two parameters that could impose adjustment between the reactants and the resultants. The reaction was calculated and the results were consistent with the experimental data.
