Based on the principles of conduction heat transfer, a thermal contact model which was predigested rationally was established.

摘 要：基于传热学基本原理建立合理简化的热接触模型。

In fact, because of using some methods of predigesting or approximating and complexity of heat changing process etc. when design to form new-type heat exchanger, we must determine the actual heat transfer performance, also to the old heat exchanger.

实际上由于设计过程中采用某些简化或近似的方法，并且换热器换热过程的复杂性等因素，对于设计制造而形成的新型换热器必须测定其实际的传热性能，对于使用过的旧的换热器也需如此。

The conducting wall in micro-tube preheats the inlet mixture by axial heat transfer. The existence of conducting wall will help to reach full reaction in the micro-tube. As the inlet velocity increases, both the existence of the surface catalytic combustion and the gas phase combustion become the limiting factors on combustion. Wall material and equivalence ratio of hydrogen/air mixture have important influence on catalytic combustion of hydrogen.

计算结果表明：表面催化反应对空间气相反应有抑制作用；在微型管道内，通过导热壁轴向间的传热，预热入口混合气体，使氢气燃烧更加充分；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；管壁材料和当量比对氢气的催化燃烧过程有重要的影响。
