环境因素对卷烟主流烟气CO释放量的影响
Influence of environmental conditions on CO release quantity of cigarette mainstream smoke
-
摘要: 运用SPSS V18.0软件,对影响主流烟气CO含量的测试大气温度、测试大气湿度、测试大气压力和气流速度进行数理统计,并将结果应用于CO测量的不确定度评价.结果表明:测试大气温度、测试大气湿度、测试大气压力和气流速度都与主流烟气CO含量存在一定相关性;通径分析表明,环境温度对CO量的总作用系数rt为0.040014;环境湿度对CO量的总作用系数rh为-0.01201;环境风速对CO量的总作用系数rf为-0.02254;环境大气压力对CO量的总作用系数rp为0.318896.忽略各不确定度分量之间的相关性,实验室卷烟主流烟气中CO测量不确定度为±0.40 mg.

Abstract: The effects of temperature,relative humidity,air pressure and air flow of environmental conditions on CO release quantity of cigarette mainstream smoke were studied with mathematics statistics by SPSS V18.0,therefore uncertainties of CO test were evaluated based on the effects.The results showed as follows:temperature,relative humidity,air flow and air pressure of environmental conditions were correlated with CO release quantity of cigarette mainstream smoke;The coefficient factors of direct and indirect effects of temperature,relative humidity,air flow and air pressure of environmental conditions on CO of cigarette mainstream smoke were rt=0.040014,rh=-0.01201,rf=-0.02254,rp=0.318896,respectively;Without the coefficients of uncertainties,the combined standard uncertainty was ±0.40 mg. -
