But the emissions of CO , CH2O , are look like the upside down " U " curve .

但是CO和CH2O的辐射呈倒U型曲线。

Through the transformation function of modifier , it successfully realizes zero emission of such harmful substance as CH2O in combustion of low-carbon fuel .

通过改性剂的转化作用，成功实现低碳燃料燃烧时甲醛（CH2O）等有害物质的零排放。

Our calculation suggests that the dissociation of CH2O on Au / CeO2 ( 111 ) surface is energetically favorable in thermodynamics .

计算结果表明，甲醛在Au/CeO2（111）表面解离为热力学有利反应。

Based on these findings , we constructed a series of surface cluster models to mimic the adsorption and reaction of CH2O ," an indicator of MSR mechanism " .

基于MC的结果，我们构建了系列表面团簇模型并考察了作为机理指示剂的甲醛在其上的吸附和化学行为。

Acetone ( C3H6O ) and formaldehyde ( CH2O ) are two typical little molecular materials of VOCs which generated in the industry fields and decorative materials .

丙酮（C3H6O）和甲醛（CH2O）是两种典型的小分子挥发性有机污染物，广泛产生于工业生产过程及装饰材料中。

The normal exhaust emissions like NOX , CO have clear distribution regularity in cylinder . The amount of CH2O is two order of magnitudes lower than that of normal emissions .

低热值气体燃料缸内主要污染物NOX、CO的分布具有明显的规律性，甲醛生成量相比常规排放物小两个数量级。

The acrylic fiber wastes ( PAN ) are hydrolyzed with alkaline at atmospheric pressure and the hydrolyzate is crosslinked by CH2O in aqueous solution to obtain a high water absorbing resin .

废旧腈纶毛线常压碱法水解物与甲醛进行交联反应，制得高性能吸水树脂。

In perchloric acid , the hydration number of uranyl ion varies from 4 to 5 with the increment of CH2O / CUO22 + mole ratio .

在高氯酸体系中，随着C（H2o）/Cuo2~（2+）增大，铀酰离子的水合数由4变至5。在盐酸体系中，铀酰离子的水合数随酸浓度的增大而减少。

The results show that the reaction has three channels , yielding the products of HOCl + CH2O , CH2O2 + HCl and CH3Cl + O2 ( 1 △), respectively .

结果表明，该反应共有三个反应通道，产物分别为HOCI+CH2O，CH2O2+HCl和CH3Cl+O2（1△）。

The key factor for sole low temperature reaction is the absence of H2O2 decomposition , and H2O2 can decompose rapidly when cylinder temperature exceeds over 1 000 K. Thus , the low temperature can not produce enough OH radical to oxidize CH2O .

蓝焰反应也不发生而仅发生低温反应的关键是H2O2分解反应的进行程度浅，H2O2只有在缸内温度达到1000K时才能快速分解，这就不能生成足够的OH自由基使甲醛转化成CO；

The route to produce HOCl + CH2O was most favorable no matter whether it was considered from the viewpoint of kinetics or thermodynamics . Thus , the channel producing HOCl + CH2O is the main one in agreement with experiment .

不论从动力学角度，还是从热力学角度看，形成产物HOCl+CH2O的通道均是最有利的，因此为主要反应通道，这与实验观察到的结果是一致的。

The net photosynthetic rate is higher on condition of full light and slight sun shading , seedlings growing is vigorous , the accumulation of CH2O is more , so dried leaf weight , branch biomass , root system biomass and total biomass per seedling all is more .

全光和弱度遮荫条件下，苗木具有较大的净光合作用速率，苗木生长旺盛，碳水化合物的积累较多，单株枝干重、根系生物量和总生物量都较大；
