For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane. Therefore besides the minimization of boundary energy in traditional bulk material, surface energy, interface energy would be considered due to the anisotropy of surface energy, interface energy being able to drive the grain growth and texture evolution in thin films.

对于薄膜特别是柱状晶薄膜，当晶粒在膜平面内的尺寸大于膜厚时，柱状晶粒的上底面和下底面的面积将大于侧面的面积，因此薄膜中的晶粒生长除像整体材料中的晶粒生长一样考虑晶界能外，还需要考虑表面能和界面能，因为各向异性的表面能和界面能将导致薄膜中的异常晶粒生长和织构变化。

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。
