| 摘 要： | 采用选择离子流动管质谱(SIFT／MS)装置，以H30^ 、N0^ 为初始离子对汽油和柴油蒸汽进行了研究，质谱分析表明，汽油和柴油主要由C—H化合物组成，包括烷烃、环烷烃、烯烃、炔烃、二烯烃以及芳香烃。在这几种成分中，烷烃都占有最大的比例；汽油蒸汽和柴油蒸汽最大的区别是柴油蒸汽中长链大分子的挥发性C—H化合物所占的比例远远高于汽油蒸汽。文中还给出了以H30^ 、N0^ 为初始离子所得到的汽油蒸汽的质谱图，以及汽油、柴油蒸汽中各种成分的定量分析结果。 |

| Abstract: | The results about selected ion flow tube/mass spectrometry (SIFT/MS) study of the different compounds in petrol and diesel vapors using H3O+ , NO+ as the precursor ions are reported. We assume both petrol and diesel are made up of CHs, including alkanes(CnH2n + 2 ) , alkenes or cyclokanes( CnH2n), alkynes or dienes( CnH2n-2 ) and aromatic hydrocarbons( CnH2n-6) . Among these compounds, the alkanes are the predominant species both in diesel and petrol vapors; The most obvious difference between petrol and diesel vapor is the presence of a greater abundance of long chain aliphatic CHs in the diesel vapor. In this paper, the mass spectra of petrol vapor using the precursors of the H3O + , NO+ and the quantitative analysis results of the compounds in the petrol and diesel vapors are also presented. |
