| 摘 要： | 利用激光解吸附电离飞行时间质谱技术获得了若干已知化学成分的气溶胶粒子的飞行时间质谱，分析标识了各类气溶胶粒子的特征离子谱峰，并对一些特征峰的形成机理进行了探讨。在此基础上，对烟花火药以及纸张燃烧产生的烟气气溶胶粒子进行了实时在线测量，通过对质谱图的分析，获得了有关此两类燃烧过程产生的烟气气溶胶单粒子的化学组成信息。

| Abstract: | The chemical composition of individual aerosol particle generated by Devilbiss 40# nebulizer was determi-ned by time-of-flight mass spectrometry (TOFMS) with laser desorption ionization (LDI). The diagnostic ions were identified and the related formation mechanism was discussed. In addition, some mass spectra of individual smoke particle produced in actual combustion processes were obtained real-time. From the mass spectra the chemical components of each class of smoke particles were analyzed. The results indicate the high efficiency of real-time LDI TOFMS chemical composition analysis for individual aerosol particle. |
