为探究不同因素对旅馆房间内PM 2.5浓度的影响及其相关性，测试寒冷地区的中小型旅馆客房内PM 2.5浓度，研究不同因素下客房内PM 2.5的浓度变化特征。采用相关分析和逐步回归分析方法研究各因素对PM 2.5浓度的影响程度，影响程度由大至小依次为室内人数、换气次数、建筑外窗缝隙穿透系数、室外风速和室内自然沉降率，相关系数分别为0.379,-0.372,-0.338,0.327,-0.303。
Abstract：In order to explore the influence of different factors on PM 2.5 concentration in hotel rooms and its correlation, the PM 2.5 concentration in small and medium-sized hotel rooms in cold areas was tested to study the change characteristics of PM 2.5 concentration in guest rooms under different factors.Correlation analysis and stepwise regression analysis were used to study the influence of each factor on PM 2.5 concentration.The order of influence was the number of people in the room, the number of air exchange, the gap penetration coefficient of the building window, the outdoor wind speed and the indoor natural settlement rate, and the correlation coefficients were 0.379,-0.372,-0.338,0.327 and-0.303,respectively.
