摘　　要：根据全封闭式空调长途客车内的环境特点,选择温度、相对湿度、空气流速、CO体积分数、CO2体积分数、甲醛体积分数、新风量等作为典型的客观评价指标;依据国际通用的主观评价调查表格,设计了空气品质主观问卷调查表;选择广州-深圳往返的长途大巴作为实测对象,对该长途客车内的空气品质状况进行了主、客观实地调查.根据车内空气品质本身及其评价的灰色特性,利用灰色系统关联理论,将所测得的影响车内空气品质的客观指标与乘客的主观感受相联系,找出对人们的主观感受影响最主要的客观指标是新风量、CO2体积浓度和温度.On the basis of the environmental characteristics of whole-closed air-conditioned coaches,the parameters of air temperature,relative humidity,air velocity,the volumetric concentration of CO,CO2,formaldehyde and the fresh air quantity are selected as typical objective assessment indexes.The subjective investigation table is designed according to the general international rules.Subjective and objective assessments of the air quality in whole-closed air-conditioned coaches,which run from Guangzhou to Shenzhen,were made.Based on the grey characteristics of the air quality in the coaches and the assessments,the relationship between the objective indexes and the passengers＇ subjective feeling was analyzed by using the grey system incidence theory.The results show that the key objective indexes,which affect the air quality in coaches,are the quantity of fresh air,the concentration of CO2 and air temperature..
