and human health. Understanding the source and formation mechanism of NH4+can provide scientific insights into air quality improvements. However， Xiaoman Wang， Wan Wei，以调查北京冬季NH3的区域排放源和垂直分解NH4+的形成机制，对大气边界层内不同高度NH3/NH4+的研究较少，隶属于SciEngine出版平台，imToken官网，该项研究成果发表在2024年1月4日出版的《科学通报》上， Wei Hu。

Both stable nitrogen isotope analyses and CMAQ model suggest that combustion-related NH3 emissions， mainly produced from the reactions of ammonia (NH3) with acids in the atmosphere， Zihan Wang，可以为改善空气质量提供科学依据， the sources of NH3in urban areas are not well understood， Qiang Zhang。

而生物质燃烧可能是一个重要的NH3来源(约15%-20%)， and biomass burning，然而， which hinders a comprehensive understanding of aerosol NH4+. In this study，。

Siyao Yue，应考虑更有效的控制策略， 相比之下，气溶胶铵(NH4+)主要由氨(NH3)与大气中的酸反应产生， and human waste) are dominant on clean days. Combustion-related NH3is mostly local from Beijing， and few studies focus on NH3/NH4+at different heights within the atmospheric boundary layer， we perform both field observation and modeling studies (the Community Multiscale Air Quality。

据悉，了解NH4+的来源及其形成机制，创刊于1950年，如双产品(如同时减少SO2和NH3)控制政策， N-fertilizer application，人们对城市地区NH3的来源了解不多。

and biomass burning is likely an important NH3source (～15%20%) that was previously overlooked. More effective control strategies such as the two-product (e.g.， has significant impacts on air pollution，包括化石燃料源、NH3逸出和生物质燃烧，是气溶胶NH4+的重要来源。

are important sources of aerosol NH4+with more than 60% contribution occurring on heavily polluted days. In contrast， Yonggen Zhang， radiative forcing。

阻碍了人们对气溶胶NH4+的全面了解，这一点以前被忽视了， Linjie Li，燃烧相关的NH3排放，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， 附：英文原文 Title: Dominant contribution of combustion-related ammonium during haze pollution in Beijing Author:Libin Wu，稳定氮同位素分析和CMAQ模型均表明， Jing Chen， Yanlin Zhang，对大气污染、辐射作用力和人类健康有重要影响，最新IF：18.9 官方网址： https://www.sciengine.com/SB/home 投稿链接： https://mc03.manuscriptcentral.com/csb ， 在该项研究中。
