为了解北京大学园区室内空气质量，对园区不同类型房屋内ＣＯ、ＣＯ２与ＮＭＨＣ（非甲烷烃）浓度进行测定。结果表明ＣＯ与ＣＯ２的浓度随季节有明显的变化〔ＣＯ：０．１～３２．１ｍｇ／ｍ３，２．７±０．９ｍｇ／ｍ３；ＣＯ２：０．０２７％～０．５２８％（０．０８４±０．０３１）％〕。燃料燃烧是住宅室内ＣＯ与ＣＯ２的主要来源，人的活动是公共场所ＣＯ２的重要来源，学生宿舍的ＣＯ与ＣＯ２主要来源于室外。室内ＮＭＨＣ的浓度（０．６０～１３．０４ｍｇ／ｍ３）受到室外环境、室内装修材料以及办公设备的使用等因素影响
In order to understand the indoor air quality of Peking University Park, the concentrations of CO, CO2 and NMHC (non-methane hydrocarbons) in different types of houses in the park were determined. The results showed that the concentrations of CO and CO2 changed obviously with seasons (CO: 0.1 ~ 32.1mg / m3, 2.7 ± 0.9mg / m3; CO2: 0.027% ~ 0.528% 084 ± 0.031)%]. Fuel combustion is the main source of CO and CO2 in residential buildings. Human activities are an important source of CO2 in public places. CO and CO2 in dormitories mainly come from the outdoors. Indoor NMHC concentration (0.60 ~ 13.04mg / m3) by the outdoor environment, interior decoration materials and the use of office equipment and other factors
