为考察标准环境温湿度调节对卷烟物理指标的影响程度。以常规支、中支、细支16个卷烟牌号21组成品卷烟为研究对象，测定其在环境温湿度调节前后的烟支重量、硬度、开吸阻、通风率等16项指标，并对检测数据进行了成对双样本均值分析与相关性分析。结果表明，温湿度调节后卷烟样品含水率增加0.924个百分点，烟丝填充值降低0.206 cm³/g，烟支硬度降低4.078个百分点，硬度检测压陷量增加0.267 mm，可能是因为调节过程烟丝吸湿含水率增加，进而导致烟丝填充性能下降。温湿度调节前后的卷烟辅材重量、开吸阻、闭吸阻、纸通风、嘴通风、总通风无显著差异，卷烟重量、净含丝量、含水率、烟丝填充值、填充密度、硬度、压陷直径、预压直径、压陷量存在显著差异。调节前后的卷烟样品预压直径之间相关系数R ²为0.994 62，压陷量之间相关系数R ²为0.918 97，均在0.90以上，相关性较强，通过相关数学模型可快速预测调节后卷烟样品硬度。

To investigate the influence degree of temperature and humidity regulation in the standard environment on the physical indicators of cigarettes. Taking 21 component cigarettes of 16 cigarette brands including regular cigarettes, medium cigarettes and thin cigarettes as the research objects, 16 indicators such as cigarette weight, hardness, opening resistance and ventilation rate were measured before and after the adjustment of environmental temperature and humidity. Paired two-sample mean analysis and correlation analysis were conducted on the test data. The results showed that after the temperature and humidity adjustment, the moisture content of the cigarette samples increased by 0.924 percentage points, the filling value of the tobacco shreds decreased by 0.206 cm³/g, the hardness of the cigarettes decreased by 4.078 percentage points, and the indentation amount of the hardness test increased by 0.267 mm. This might be due to the increase in moisture absorption of the tobacco shreds during the adjustment process, which in turn led to a decline in the filling performance of the tobacco shreds. There were no significant differences in the weight of cigarette auxiliary materials, open suction resistance, closed suction resistance, paper ventilation, nozzle ventilation, and total ventilation before and after temperature and humidity adjustment. However, there were significant differences in cigarette weight, net filament content, moisture content, filament filling value, filling density, hardness, indentation diameter, pre-pressing diameter, and indentation amount. The correlation coefficient R ² between the pre-pressing diameters of cigarette samples before and after adjustment was 0.994 62, and the correlation coefficient R ² between the indentation amounts was 0.918 97, both reaching above 0.90, with a strong correlation. Through the relevant mathematical model, the hardness of cigarette samples after adjustment can be quickly predicted.
