2000年1～6月期间,美国国家大气研究中心(NCAR)和中国科学院大气物理研究所的科学家发展了一套自动的气相色谱系统和分析方法,用于分析大气中的挥发性有机物.此系统性能稳定,重复性好,对美国大气研究中心附近的大气进行了采样分析.作者简单介绍了此自动系统以及采样分析结果.  相似文献   

The Influence of O3, Relative Humidity, NO and NO2 on the Oxidation of α-Pinene and Δ3-Carene

Upto 13% of -pinene and ³-carene had reacted after 213 s in this dark experimental set-up, where O₃, NO and NO₂ were mixed with terpenes at different relative humidities (RHs). The different experiments were planned according to an experimental design, where O₃, NO₂, NO, RH and reaction time were varied between high and low settings (25 and 75 ppb, 15 and 42%, 44 and 213 s). An increased amount of -pinene and ³-carene reacted in the chamber was observed, when the level of O₃, NO and reaction time was increased and RH was decreased. In the study, it was found that different interactions affected the amount of terpene reacted as well. These interactions were between O₃ and NO, O₃ and reaction time, NO and RH, and between NO and reaction time.  相似文献
