| 摘 要： | 本文采用气相色谱－质谱联用方法，对燕山石化地区不同生产区域的大气样品，定量地进行非甲烷碳氢化合物（ＮＭＨＣ）的分类测定。本方法可以鉴定Ｃ２－Ｃ１１共六十多个色谱峰。实验表明，燕山石化地区烷烃、烯烃和芳香烃等各类碳氢化合物均具有较高浓度，是对ＮＭＨＣ有重要贡献的一个工业源。本文还参照各大气样品的不同来源，分析了ＮＭＨＣ的排放特征，从而确定了燕山石化区ＮＭＨＣ排放的典型物种。

| Abstract: | Gas samples from different sites in Yanshan petrochemical region have been quantatively measured by gas chromatography-mass spectrometry combination. More than sixty chromatogram peaks can be identified in the range C2-Cu- The results show that the alkane, alkene and aromatic hydrocarbons in Yanshan are all in high concentration. Consequently, petrochemical industry contributes greatly to atmospheric NMHC. Considering for the different sources of these samples, the emission character of atmospheric NMHC is analysed, from which the typical NMHC species in atmosphere of Yanshan is estimated. |
