| 中文摘要: |
| 采用热脱附-气相色谱/质谱和顶空气相色谱/质谱分别对车间硫化烟气和实验室模拟硫化烟气进行分析，并研究两者间的关系。结果表明：车间硫化烟气热脱附优化条件为脱附温度 180 ℃，脱附时间 15 min，冷阱温度 －65 ℃；以顶空进样器模拟橡胶硫化过程来进行实验室模拟硫化烟气成分分析；相同胶料的车间硫化烟气检出成分少于实验室模拟硫化烟气检出成分，但两者大部分成分相同，相同成分多为毒性较大的含氮类化合物和苯等；车间硫化烟气与实验室模拟硫化烟气解析量基本呈正相关。 |

| In this study，the workshop vulcanization fume and laboratory simulated vulcanization
fume were analyzed by using thermal desorption-gas chromatography/mass spectrometry（TD-GC/MS）
and headspace gas chromatography/mass spectrometry（HS-GC/MS） respectively，and the relationship
between the two fumes was studied. The results showed that the optimum thermal desorption conditions of
the workshop vulcanization fume were as follows：desorption temperature was 180 ℃，desorption time was
15 min，cold trap temperature was －65 ℃. The components of the laboratory simulated vulcanization fume
were analyzed by simulating rubber vulcanization process with headspace sampler. For the same compound，
the detected components of the workshop vulcanization fume were less than those of the laboratory simulated
vulcanization fume，but most of them were the same，and most of the same components were nitrogencontaining
compounds and benzene with high toxicity. The analytical quantity of the workshop vulcanization
fume was basically positively correlated with that of the simulated laboratory fume. |
