主要观点总结
文章研究了通过OH引发的含有β-蒎烯和d-柠檬烯混合物的二次有机气溶胶（SOA）的生成，以评估它们氧化产物之间的化学相互作用程度。SOA样品在环境烟雾箱中制备，并使用超高效液相色谱耦合电喷雾电离高分辨率质谱（UPLC-ESI-HRMS）进行离线分析。
关键观点总结
关键观点1: SOA成分分析
研究发现含有β-蒎烯的SOA相比仅含有d-柠檬烯的SOA，具有更高比例的低挥发性寡聚化合物。
关键观点2: SOA组成预测
通过单个前驱体SOA的质量谱的线性组合，可以准确预测混合SOA的公式分布和信号强度。
关键观点3: 交叉反应的影响
色谱分析显示混合SOA中的同分异构氧化产物的分布存在交叉反应的影响，但总体来说，β-蒎烯和d-柠檬烯在OH引发的氧化过程中彼此独立，只有微妙的交叉反应影响特定氧化产物的产量。

Secondary Organic Aerosol from OH-Initiated Oxidation of Mixtures of d-Limonene and β-Myrcene （ 由于标题字数限制， 中文标题为自翻，以原标题为准） Abstract The chemical composition and physical properties of secondary organic aerosol (SOA) generated through OH-initiated oxidation of mixtures containing β-myrcene, an acyclic monoterpene, and d-limonene, a cyclic monoterpene, were investigated to assess the extent of the chemical interactions between their oxidation products. The SOA samples were prepared in an environmental smog chamber, and their composition was analyzed offline using ultraperformance liquid chromatography coupled with electrospray ionization high-resolution mass spectrometry (UPLC-ESI-HRMS). Our results suggested that SOA containing β-myrcene showed a higher proportion of oligomeric compounds with low volatility compared to that of SOA from d-limonene. The formula distribution and signal intensities of the mixed SOA could be accurately pred
