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。

The standard workpiece of the ring compression test by Lee and Altan will be used in this report. The specimen will first annealed to eliminate the internal stress and then through different ways of machining to produce different roughness of surface and different direction of machining marks.

The SERS of various concentration of Reactive Red, Acid Red, Acid Black, Direct sol orange and Calcon Carboxylic Acid adsorbed on silver colloid are studied by micro-Raman spectrometer. It has been found that the SERS intensity of absorbed molecules is mainly from the nearest molecule layer to the surface of silver colloid. That is, SERS has its single layer saturation effect. 2. The technique of direct deposition of silver colloid on a Kaolinite surface is first described.

以银溶胶作基底，利用显微拉曼光谱仪对不同浓度的活性艳红、酸性红、酸性黑、直接耐晒橙四种染料和钙羧酸指示剂的表面增强拉曼光谱进行了研究，结果表明，由于表面增强拉曼散射具有单分子层饱和效应和银溶胶系统对荧光的猝灭率很高，能吸附染料分子并增强拉曼散射的强度，且吸附分子的表面增强拉曼散射的强度，主要是由于最靠近银溶胶的一层分子的增强，而第一层以外的分子贡献很小。
