【摘要】 <正>柴油机排放的颗粒物含量很高,约为汽油机的30～80倍。颗粒物中吸附的有机化合物可以诱发人类发生癌变和呼吸系统的疾病,因而被认为是对人类健康造成不利影响的最大因素之一。因此对柴油机尾气颗粒物中有机化学组分的分析检测成为国家相关管理部门和柴油机生产及使用部门的重要课更多还原

【Abstract】 A thermal desorption method for analysis of the volatile components on carbon particles,which were produced by the combustion of diesel oil,has been developed.The collection equipment of carbon particles was designed and the pyrolysis instrument was used as the thermal desorption equipment.The collected carbon particles were injected into the pyrolysis instrument and desorbed at the temperature of 700℃.All the volatile components were analyzed by gas chromatography -mass spectrometry(GC -MS).The results showed that the volatile component on carbon particle could be rapidly analyzed.The method provided a guidance to the further research of the burning behaviors of the diesel oil.更多还原
