uhc的音标

The air humidified combustion may cause that NOx emission dramatically reduce, CO and UHC emission slightly increase, the spectrum of pressure oscillation within combustor changes, and the temperature field at combustor exit becomes more poor.

研究结果表明，空气加湿燃烧导致NOx排放显著下降，CO和UHC排放略有上升，燃烧室中压力振荡的频谱产生了变化，燃烧室出口温度场畸变加剧。

It was detected that the temperature distribution within combustor, the temperature field at combustor exit, the pollutant emission ( i.e. NOx, CO and UHC) and the stability of combustion were affected by humidity.

实验中发现，燃烧室内温度分布、出口温度场、污染物生成（即NOx、CO、UHC）及燃烧稳定性都受到加湿度的影响。
