室内空气质量卫生综合评价最佳模式的比较

RESEARCH ON OPTIMUM MODE OF COMPREHENSIVE ASSESSMENT METHOD OF INDOOR AIR QUALITY

目的:选择和设计室内空气综合质量评价模式。方法:利用几何模式、Nemerow模式、姚志麒模式、公共场所卫生质量指数评价模式和“修改模式”对3份调查资料进行P值计算、排序、分辨效能比较和发生分辨失效的原因分析。结果:“修改模式”计算出的P值比其他模式具有更好的分辨效能和警示作用,尤其是平均分指数(Iav)和最大分指数(Imax)分别相同而分指数超标率不同的两资料,或分指数超标率相同而最大分指数(Imax)超标倍数不同的两资料,“修改模式”都能有很好的分辨效能。特别是仅有1项分指数大于1,其他分指数接近零的资料,也能保证P值大于1,具有警示作用。结论:“修改模式”P值计算结果分辨效能好,排序合理,符合客观实际,具有警示作用,是室内空气质量卫生综合评价的比较理想的模式。

Objective:To select and design modes of comprehensive assessment method of indoor air quality.Methods:With geometric mode,Nemerow mode,Yao Zhili mode,assessment mode of health quality index and the 'modified mode' based on the P value assessment,the calculation,the resolving potency of three investigation materials of indoor air quality and the cause of the resolution failure were analysed.Results:The P value calculation by the 'modified mode' had a better resolving potency and warning power than other modes.Especially between two investigation materials of which the average index(Iav) and the maxim index(Imax) were the same while the super-scale rates were different,between two investigation materials of which the super-scale rates also were the same while the rates of the multiple of the maxim index(Imax) were different,the 'modified mode' had a good resolving potency.In particular in the material of which only one index was over 1,and other indexes were close to zero,the P value was insured over 1,which was really a warning.Conclusion:The P value calculation by the 'modified mode'is simple and practical and the air quality can be shown objectively by it,so it is a good assessment method.
