outer diffusion controlling

5 mm,there is no effect on the reaction for the internal diffusion and external diffusion.

5 mm时,内、外扩散对反应均无影响。

The results show: external diffusion is the main resistance for mass transfer,and increasing air velocity and decreas.

研究结果表明,外扩散过程是传质的主要阻力,增大风速、减小吸附剂颗粒直径是减少传质阻力的有效措施。

Based on the determined kinetic model equation of non-steady reaction, the new method for obtaining experimental data of single continuous run to be used to evaluate the effect of external diffusion on multiphase reaction and to determine experimental conditions of eliminating external diffus.

在确定非稳态反应动力学模型基础上,通过反应实验及数据处理,建立了用一套连续反应实验数据考察外扩散对多相反应过程影响及确定消除外扩散影响实验条件的新方法。

The plan of renovation process is put forward out and accepted by the producers and customersthrough the experiment and analysis on the out of square in the end of hot-rolled H-beam.

通过对热轧H型钢翼缘内并外扩缺陷整修的试验和分析,提出了整修工艺方案,并在实践中得到了生产厂和用户的认可。
