居室装修污染物与空气品质的灰色关联度分析

Analysis of grey incidence about contamination produced by building materials and indoor air quality

将灰色系统理论引入居室空气品质的研究中,运用灰色系统关联分析方法把客观所测得的污染物浓度与人们的主观感受结合起来,分析了装修材料引起的居室污染物与空气品质的主观评价之间的关系———室内污染物质量浓度初值像的曲线几何形状与主观感受的曲线几何形状越相似,曲线之间的距离越小,对主观感受的影响越大。此外,通过对居室内污染物质量浓度和室内空气品质主观评价的灰色关联度的计算,指出甲醛、苯、氨这三种污染物是对人体主观感受影响较大,导致居室空气品质低劣的主要污染物.

Grey system theory is introduced to research the indoor air quality. Concentration of contamination determined objectively is connected with people's feelings by way of Grey system incidence to analyze the relationship between indoor air contamination produced by building materials and subjective assessment.The result shows that if the distance from the curve that represents the concentration of contamination to the curve that represents subjective assessment is near,the contamination will affect the subjective assessment seriously.It is found out that formaldehyde,benzene and ammonia are the main contaminations that aggravate the indoor air quality according to the analysis of Grey incidence about contamination produced by building materials and indoor air quality.
