摘　　要：为考察不同温湿度平衡时间对卷烟主流烟气中氢氰酸释放量的影响,在标准温湿度条件下,分别选择不同的平衡时间对6种卷烟样品处理后,应用连续流动分析仪对卷烟主流烟气中氢氰酸释放量进行测试,连续考察了120 d。结果表明:①平衡120 d内,卷烟样品抽吸口数没有明显变化;②平衡120 d内,不同盒标焦油量的卷烟主流烟气中HCN释放量没有明显变化;③平衡120 d内,不同类型卷烟主流烟气中HCN释放量没有明显变化。因此,在平衡120 d内对样品HCN进行测定,均能得到准确结果。In order to investigate the influence of the equilibrium time on the yields of hydrogen cyanide in mainstream smoke,6 cigarette samples were treated under different equilibrium time for 120 d. The deliv- eries of hydrogen cyanide in mainstream smoke was determined by segmented flow analysis. The results showed that ①within 120 d, the suction port number of cigarette samples have no significant changes. ②within 120 d, the yields of HCN in mainstream smoke of different tar-contained cigarette samples have no significantly changes. ③within 120 d, the yields of HCN in mainstream smoke of different type cigarette samples have no significantly changes. In a word, the results of the deliveries of hydrogen cyanide in main- stream smoke were accurate within 120 d
