The computational results indicate that surface catalytic combustion restrains gas phase combustion. Inlet velocity and tube diameters have important influence on catalytic combustion of hydrogen. For smaller inlet velocities,reaction is dominated by gas phase combustion. As the inlet velocity increases,there exist both surface catalytic combustion and gas phase combustion. For bigger inlet velocities,reaction is dominated by surface catalytic combustion. The temperature of flame core decreases with the decrease of tube diameter.

计算结果表明，表面催化反应对空间气相反应有抑制作用；入口速度和管径对氢气的催化燃烧过程有重要的影响，在入口速度较小时，燃烧主要是空间气相化学反应，随着入口速度的增大，燃烧过程同时存在着表面催化反应和空间气相反应两种控制因素，在入口速度较大时，燃烧主要是表面催化燃烧过程；随着管径的减小，微型管道内反应的最高温度降低。
