AbstractTo investigatetheinfluencedegreeof temperatureand humidityregulation in the standard environment onthe physical indicators of cigarettes.Taking 21 component cigarettes of 16 cigaretebrands including regular cigarettes，medium cigarettesand thincigaretesas theresearch objects，16 indicatorssuch ascigarette 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. Theresults showed that after the temperature and humidity adjustment，the moisture content of the cigarette samples increased by O.924 percentage points，the filling value of the tobacco shreds decreased by 0.206cm³/g ，the hardness of thecigarettes decreased by4.O78percentage points，and the indentation amountof thehardness test increased by 0.267 mm.This might be dueto the increase in moisture absorption of the tobacco shreds during theadjustment process， whichinturn led toadeclineinthe filing performanceof the tobacco shreds.There wereno significant diffrences in the weight of cigarette auxiliary materials，open suction resistance，closed suction resistance，paper ventilation，nozle ventilation，andtotalventilationbeforeandaftertemperatureandhumidityadjustment.However，there weresignificant differences incigarete weight，netfilamentcontent，moisturecontent，filamentfillingvalue，fillingdensityhardess， indentation diameter， pre-pressing diameter，and indentation amount. The correlation coefficient R² between the prepressingdiameters of cigarettesamples beforeand after adjustment was O.994 62，and thecorrelation coefficient R² （204号 betweenthe indentation amounts was 0.918 97，both reaching above0.90，witha strong correlation.Through therelevant mathematical model， the hardness of cigarette samples after adjustment can be quickly predicted.

环境湿度会影响卷烟的焦油、烟碱、一氧化碳等烟气指标和质量、硬度、吸阻等物理指标。卷烟烟丝、卷烟纸均是高比表面积的多孔物质，对环境湿度具有较高的敏感性。因此，测试卷烟的烟气和物理指标前需进行温、湿度调节，以保证测试样品保持相同的含水率1。目前，关于卷烟物理指标的研究主要集中在环境温湿度、切丝宽度[3、烟丝结构、生产方式5卷烟机参数等方面，但关于环境温湿度调节对各项指标检测结果的影响研究有待进一步深人。宋旭艳等研究了环境湿度对卷烟理化指标及感官质量的影响，发现环境湿度与卷烟烟支重量和吸阻呈正相关。王迅等8研究认为，不同综合测试台在细支卷烟质量、长度、圆周、总通风、吸阻等测量结果方面存在一定差异。董浩等研究认为，样品放置方式对卷烟单支质量等物理指标的影响具有一定差异，其对卷烟硬度的影响较大。本文通过成对双样本均值分析和相关性分析，考察标准环境温湿度调节对卷烟重量、吸阻、硬度、含水率等16项物理指标检测结果的影响，为缩短温湿度调节及检测时间提供参考。
