NO+NH3 temperature-programmed reaction runs over reduced catalyst samples pretreated with various oxidizing species showed that both NO2 and HNO3 were able to reoxidize the V catalyst at much lower temperature than gaseous O2: furthermore, they significantly enhanced the NO + NH3 reactivity below 250 C via the buildup of adsorbed nitrates, which act as a surface pool of oxidizing agents but are decomposed above that temperature.

不+NH3 温度-规划反应奔跑结束减少催化剂样品预先处理与各种不同的氧种表示两者的没有 2 和 HNO3 能够到再氧化 V 催化剂在非常低的温度超过气体的 O2：此外，他们重要地可提高的那不+ NH3 反应度在下面 250？C 经由组织吸附硝酸盐，哪一个行为当做一表面池氧代理人但是被分解上方哪一温度。

Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission;the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB,but also adapt to the gas's characteristic involved with H2S,CO,and other poisonous components without supplied m...

通过选用耐油性好的橡胶隔振器减少固体传声，可降低噪声约2 dB；设置半封闭式机组隔声屏障可降低生产车间工作区域内的噪声达13 dB，并且适合瓦斯发电气源中含有H2S、CO等有毒有害气体的特点，不需增加强制通风措施；在生产车间四周墙壁和顶棚上敷设吸声体，最大可降低空间噪声8 dB；根据瓦斯发电机排烟噪声频谱特性设计的阻抗复合式消音器的消音量可以达到30 dB以上。

Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission; the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB, but also adapt to the gas's characteristic involved with H2S, CO, and other poisonous components without supplied mandatory ventilation; locating the noise absorbers on the walls and ceiling of workshop can reduce noise by 8 dB; the exhaust silencer's elimination volume can reach above 30 dB which is designed in accordance with the exhaust noise spectrum characteristic of gas-combustion generator. By the combination of these measures, the noise of the gas- combustion generator will be under effective control, so that the gas power plant's noise pollution problems can be resolved.

But our interest is not only in Hamlet the tragic hero, for this play is also Shakespeare''s most detailed expose of a corrupted court-"an unweeded garden" in which there is nothing but "a foul and pestilent congregation of vapours." By revealing the power-seeking, the jostling for place, the hidden motives, the courteous superficialities that veil lust and guilt, Shakespeare condemns the hypocrisy and treachery and general corruption at the royal court.

The results show that for a supersonic shear layer without reaction, a disturbance can make the shear layer become unstable, this results in one vortex or more than one vortex. The combination and seperation of vortex can intensify the mixing. But it is not easy for supersonic reacting shear layer with exotherm to become unstable with disturbance, and the effect duration is very long.

结果表明，对完全气体的超声速剪切层流动，一定的激励方式能使原先较为稳定的剪切层流动变得不稳定，产生单涡或多涡结构，发生多涡间的合并，使混合加剧；但对于存在放热现象的反应超声速剪切层流动，外加激励方式不易使流动从稳定变为不稳定，而且外加扰动的作用特征时间也较长，实际应用前景不乐观。

Because plants sop up carbon dioxide, running cars on ethanol produced from corn or other plants could slow down the rise in atmospheric leels of this greenhouse-warming gas.

植物释放二氧化碳，而由谷物或其他植物的制造的酒精为燃料的汽车能够降低大气中能造成温室效应的气体的含量。

At least in the nearby universe, gas dissipation is required to produce the high densities observed in bulges out of the low densities in disks.

至少在邻近的宇宙，气体的消散是必需的，以此来形成椭圆星系的高密度和漩涡星系的低密度。

Glucose was gasified in various temperature, pressure and concentration of the reactant mixture. The results were analyzed carefully, and the effects of the parameters on the gasification were discussed and some key points were concluded.
