An oxidation catalytic converter is mainly used for catalytic conversion of unburned THC and CO in the exhaust gas and its primary principle is to reduce the hazardous materials by farther oxidating of the unburned intermediate reactive products in the exhaust gas .

氧化型催化转换器主要用来催化转换 排气 成分 中 的 THC和CO，其主要工作原理是进一步氧化排气成分中的未完全燃烧的中间产物，以降低排气成分中的有害物质。

But the unburned HC and CO increase which can be reduced by a catalyze converter since the exhaust gas temperature is always more than 400 ℃ and higher than the required temperature of the catalyze converter .

但是， HC和CO较原机有所增加，由于 排气温度高于400℃，可以通过催化转化器将其消除。

Within an oscillation combustion period the evolution of detonation and deflagration modes is affected by triple structure thermodynamics of unburned gas within reaction induction region and disturbance of reflected waves from wall .

在一个振荡燃烧周期内，爆燃和爆轰形态的不稳定发展受三波点波系结构、化学反应诱导区内 未 燃 气体的热力学状态以及壁面反射波扰动的影响。

From the results of experiments and theoretic analysis it shows that the obstacle wrinkles flame front surface and enlarges the turbulence intension of unburned gas before flame and flame inner flow field . The flame acceleration is improved .

实验与理论分析表明，障碍物的存在引起火焰前锋褶皱度增大，提高了火焰前方 未 燃 气体以及火焰内部流场的湍流强度，促进了火焰加速。

The turbulent kinetic energy of unburned gas in front of flame can also be enhanced by the accelerated flame . The positive feedback effect of the turbulent unburned gas and flame are generated and displayed .

加速火焰还会诱导其前方的 未 燃 气体湍流强度 迅速增加，强湍流的未燃气体与火焰会产生正反馈作用。

Because of absence of unburned pulverized coal and coal ash the change in composition from primary slag to final slag is small so the slag formation in gas injection blast furnace is improved .

由于没有 未 燃煤粉和煤粉灰分的加入，初渣到终渣的成分变化较小，改善了喷 煤气高炉的成渣过程。

Heat loss due to unburned gas

化学 不 完全 燃烧热损失

According to the discharging function more unburned gas was discharged and the flame was longer .

根据排代作用， 喷出 管道 未 反应 气体 较多，火焰较长。

The expansion of combustion can promote the unburned gas flow in front of flame .

研究发现，燃烧膨胀会导致火焰阵面前的 未 燃 气体产生流动。

It was obtained that the porous structure and huge surface-area of the unburned carbon was benefit to the Hg adsorption in flue gas .

燃煤 飞 灰炭粒所具有的多孔隙结构和巨大比表面积有利于吸附脱除烟道 气中Hg污染物。
