摘　　要：为考察烟草中含氮化合物在卷烟燃烧过程中生成氰化氢(HCN)的规律,采用卷烟模拟燃吸装置研究了燃吸温度、燃吸气氛含氧量及其流速、升温速率等条件对烟草中蛋白质、脯氨酸和天冬酰胺生成HCN的影响。结果表明:1燃吸温度、燃吸气氛含氧量和升温速率对蛋白质、脯氨酸和天冬酰胺生成HCN均有明显的影响,而载气流量的影响较小;2富氧气氛、低速燃烧、低温环境可抑制前体成分或烟草裂解生成HCN。In order to find out the rule of hydrogen cyanide （HCN） formation from the nitrogenous compounds in tobacco during cigarette combustion, the effects of puffing temperature, oxygen content in puffing atmosphere and flow rate thereof, and heating rate on the HCN formation from the protein, proline and asparagine in tobacco were investigated with a cigarette smoking simulator. The results showed that： 1） Pyrolysis temperature, oxygen content in puffing atmosphere and heating rate obviously affected the HCN formation from protein, proline and asparagine, while the effect of carrier gas flow rate was slight. 2） Rich oxygen atmosphere, low burning rate and low circumstance temperature inhibited HCN formation from the pyrolysis of its precursors or tobacco.
