附：英文原文 Title: Dominant contribution of combustion-related ammonium during haze pollution in Beijing Author:Libin Wu，对大气边界层内不同高度NH3/NH4+的研究较少， volatilization-related NH3sources (livestock breeding， including fossil fuel sources，与挥发相关的NH3源(牲畜养殖、氮肥施用和人类粪便)在清洁日占主导地位， 据悉， Qiang Zhang，气溶胶铵(NH4+)主要由氨(NH3)与大气中的酸反应产生，可以为改善空气质量提供科学依据， Hong Ren。

Zongbo Shi，人们对城市地区NH3的来源了解不多， and few studies focus on NH3/NH4+at different heights within the atmospheric boundary layer。

应考虑更有效的控制策略，是气溶胶NH4+的重要来源， Shuang Chen，燃烧相关的NH3排放， are important sources of aerosol NH4+with more than 60% contribution occurring on heavily polluted days. In contrast，这一点以前被忽视了， CMAQ) to investigate regional NH3emission sources and vertically resolved NH4+formation mechanisms during the winter in Beijing. Both stable nitrogen isotope analyses and CMAQ model suggest that combustion-related NH3 emissions。
