| 摘 要： | 用模式了取样法集汽车柴油发动机尾气中多环茎烃，并重点对ＢａＰ采样方法进行研究，结果表明，该法采样时间仅１－２ｓ，采样体积为３３０ｍｌ（ｓ．次），回收率７７．６％，９次重复的变异系数为２９．６％，测得ＢａＰ的数据与国际ＩＳＯ规定的ＣＶＳ定容取样法可比。

| Abstract: | new method, operomode sampling method was presented for the first time for collecting polycyclic aromatic hydrocarbons (PAHs) in the exhaust from diesel engines. With benzo-a-pyrene(BaP) as a main index, the efficiency, precision and accuracy of the sampling technique were investigated. Results show that the operomode sampling method was a simple, rapid and reliable method. During the bench test of diesel engines it could be used to collect PAHs compounds quickly from exhausts of diesel engines under different operating modes such as idle motion, free acceleration etc. The BaP data measured were comparable with those from the constant volume sampling(CVS) method. |
