空气控制

NO peak location has biggish fluctuation with blend ratio, so must pay more attention to air-condition combustion.

混煤组分比例改变导致NO波峰对应的反应时段有较大的波动，在采用空气分级控制氮氧化物生成的措施时，需要考虑这一因素的影响。

Sulfur corrodible sites and their characteristics were introduced of the prefractionation system, air preheaters of heating furnace and product air coolers etc,and chlorine corrodible sites and their characteristics were also presented of the thermocouple casing tubes, product air coolers and fire arrestors of heating furnace etc in the catalytic reforming and diesel hydrogenated unit s.

介绍了中国石油哈尔滨石化公司催化重整及柴油加氢装置在预分馏系统、加热炉空气预热器、加氢装置反应产物空冷器等处易发生硫腐蚀和在预加氢热偶套管、加氢反应产物空冷器、加热炉阻火器等处易发生氯腐蚀的部位及其表现特征，指出装置在低温(不高于120℃)、含水、容易被堵塞的部位易形成HCl-H2S-H2O腐蚀体系，分析了腐蚀原因和介质来源，总结和提出了开好原油的电脱盐、采用脱氯技术、加强对加热炉的排烟温度控制和腐蚀介质的精制与净化、加大空冷器的注水量等针对性防腐经验和措施。

We found that this lowered VOCs by a third," Fjeld says."A similar process helps plants to control humidity, helping to prevent coughs and sore throats.

我们发现植物的分解变化作用能使空气中的VOCs减少了三分之一，&Fjeld说，&另一个类似过程则是帮助植物来控制湿度，从而避免了咳嗽和咽喉疼痛症状的发生。

The oxidant 〓 plays indirect role in dissolving gold, and mainly controls the mix potential of Au in the alkaline thiourea solution. In which the "mix potential"is the decisive factor affecting the dissolution of gold. The reaction driving force is enough to have formamidine disulfide oxidize Au to Au〓 at the potential of about 0.4V. And then thiourea molecular complexes with Au〓 ion soon, which causes the fast dissolution of gold in the alkaline thiourea media. The dissolved weight of gold in 0.25 M thiourea solution with 0.05M Na〓SO〓 and 0.1M 〓 of pH 12. 5 by air at the temperature of 303K is 7. 8mg·cm〓 within 1hr.

在碱性硫脲溶金过程不起直接作用，而是通过S〓O〓来控制二硫甲脒有效形成的金在溶液中的混合电位；&混合电位&是影响碱性硫脲溶液溶金与否的决定性因素，在0.4V左右，有足够的推动力致使二硫甲脒氧化Au成Au〓，随后硫脲与Au〓络合形成稳定的络离子Au〓，从而使金快速溶解；温度为303K、pH为12.5时，在含0.05MNa〓SO〓、0.1M 〓及0.25M硫脲的溶液中，鼓入空气，金的溶解量在1hr内为7.8mg·cm〓；铜只有微量溶解，银、镍、铁则几乎不溶解。

Unfortunately, though, because of the aerodynamics and gyroscopic effects of the blades, all these controls are related.

不幸的是，由于桨叶的空气动力学效应和回转效应，所有这些控制都是相关联的。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
