查询词典 react on

The results indicate that improving temperature to reflux, using low polarity solvent as dispersion medium and proper molar ratio of tetrabutyl titanate to stearic acid can bring out good modification. The function of tetrabutyl titanate is to react with the surface hydroxyl groups and adsorbed H2O on the powder particles to produce new binding sites such as M—O—Ti—OC4H9and M—O—Ti—OH, which can easily react with the carboxylic acid. As temperature increases from room temperature to reflux temperature, the reactions between RCOO- and Ti change from coordinate bonds to covalent bonds, which makes the carbon chains of stearic acids more strongly bound with the powder particles surface.

研究结果表明，提高处理温度、适当增加复合改性剂中硬脂酸的量并选用极性弱的有机溶剂可达到比较理想的改性效果；钛酸四丁酯的作用是与粉体粒子表面的羟基以及吸附水反应产生偶联点，如M—O—Ti—OH，这些偶联点易于与羧酸反应；在低温时RCOO-与偶联点的Ti之间以配合物的形式发生作用，在回流温度下处理时，主要发生酯化反应，使硬脂酸更牢固地嫁接到粉体粒子表面，改性效果更好。

人的现代化则在作为教育现代化核心的同时，反作用于教育现代化并使其不断深化和拓展。

They react on this one problem very slow, very loath.

他们在这一问题上反应很慢，很不情愿。

All this we do to detect eventually mistakes / problems as soon as possible so we can react on it right away.

As one of the most important functional elements, Building envelope which can be used as function of thermal insulation, sound insulation , waterproof , fireproof etc, should react on the effective applyment of energy.

建筑围护结构是建筑物最重要的功能构件，起到保温、隔热、隔声、防火、防水等多方面的重要作用；对节能而言，它在整个建筑系统中起到有效利用能源的主要作用。

The organism cleared the dust by means of dissolution, enwrapping, winding or in the way of biochemical dissolution, and the fibre became shortened, broken, bifurcated, ends-rounded, and also it could dissolve, transfer and chemically react on surface.

机体以吞噬、包裹、缠绕，或以生化溶解方式排解粉尘，纤维自身则出现变短、尖部圆化、折断、分叉现象，也可以溶解、迁移、表面化学反应等。

Since H〓S and SO〓 adsorbed on TiO〓 could react with each other and TiO〓 is the medium of their electron transfer, thus SO〓 could not be adsorbed quite strong on the active site of TiO〓, which makes it more resistant to sulfating and increase the stability of catalyst. Finally, the model and mechanism of the reduction of SO〓 by NH〓 to elemental sulfur is advanced as follows: on the sulfide catalyst, ammonia is decomposed to N〓 and H〓, and H〓 reacts with SO〓 to form the intermedium of H〓S; then H〓S and SO〓 react as Claus reaction on TiO〓 catalyst.

反应系统中过量水蒸气的存在使催化剂表面某些活性位被水蒸气抑制使活性和选择性有较大幅度降低，但这种影响是可逆的，不会造成催化剂永久性中毒；另外当单质硫和水蒸气同时存在时，在〓催化剂上能够生成硫化氢和二氧化硫，而且由于硫化氢和二氧化硫化学吸附能力不同而导致它们的脱附顺序不同，硫化氢的生成温度总是低于二氧化硫的生成温度，说明过量水蒸气的存在会导致氧化物催化剂上逆克劳斯反应的发生；而在硫化物催化剂上几乎没有硫化氢和二氧化硫生成，说明硫化物催化剂能够抑制逆克劳斯反应的发生。

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
