摘　　要：设计了用热电偶连续测定模拟燃吸香烟过程中过滤嘴内部温度的方法,测得了模拟燃吸香烟过程中蚕丝过滤嘴和二醋酸纤维素纤维过滤嘴内部温度曲线。结果表明,在模拟燃吸香烟过程中蚕丝过滤嘴内部温度的变化比二醋酸纤维素纤维过滤嘴小得多。分析认为,与二醋酸纤维素纤维相比,蚕丝纤维的直径要小得多,在蚕丝纤维表面有较多的特殊官能团和反应活泼性基团,这些均有利于蚕丝纤维吸附香烟烟气化合物,可有比较多的烟气化合物分子将烟气流热量传给蚕丝纤维,不至于使蚕丝过滤嘴内部产生较大的升温。An experiment was designed to continuously measure the change of temperature inside the filter tip with a thermocouple in the course of simulating someone smoking the cigarette.The temperature variation curves inside the silk filter（SF） and cellulose diacetate filter（CDF） tips was tested.The results indicated that the change of temperature inside SF is much smaller than that inside CDF in the course of simulating someone smoking the cigarette.According to our analysis,when compared with cellulose diacetate,silk has smaller diameter,and on its surface exist more special functional groups and reactive groups,making it beneficial for adsorption of cigarette smoke compounds whose molecules transfer more heat from the smoke flow to the silk.Thus,the temperature rise inside SF tip is lessened.
