基于规范变换的空气质量指数公式的广义普适性

Universal availability of the air quality index formulae based on the normalized transformation principle

为了建立形式简洁、计算简便和普适的室内、外空气质量评价的指数公式,基于室内空气质量标准(GB/T 18883—2002),适当设置室内空气各指标"参照值"及指标值的规范变换式,并对各指标的标准值进行规范变换,使室内空气15项指标的各级标准规范值的变化范围与室外空气7项指标的同级标准规范值的变化范围一致。因此,基于规范对称性原理,用免疫进化猴王遗传算法优化得出的适用于7项指标规范值的室外空气质量评价的6个普适指数公式也同样适用于15项指标规范值的室内空气质量评价。以邯郸居民区和广州公共场所2个室内空气质量评价为实例,对6个指数公式的实用性进行了检验。结果表明,6个指数公式的评价结果是彼此和谐和一致的,也与传统的指数公式法的评价结果相符合。6个指数公式是目前室内、外空气质量评价中最简化、规范、普适和统一的方法。

This paper aims to work out a few index formulae for assessing the environmental quality of the inside and outside the atmospheric conditions,which are characteristic of the features of being simple in form,easy in calculation and universal in application.Thus,it is on such a basis of the indoor air quality standards（GB/T 18883—2002） that we have proposed the essential formulae of the air quality so as to make the varied ranges of the normalized index systems consisting of 15 indexes in one single grade standard of the indoor air,which should be in conformity with those of the normalized index values of 7 ones for the same gradation standards of the open-air space,so that it can properly be set up as a reference to the normalized transformation form.In so doing,it would be easy and logic to make the formulae into a normalized transformation in accordance with the grade standards for each index of the indoor air.Thus,it is also possible to optimize the 6 universal index formulae by means of the monkey-king genetic algorithm with immune evolutionary（MKGAIEA）,which are also suitable for environmental quality assessment of 7 normalized index values of the outdoor air.What is more,the formulae can also be made fit for the environmental quality assessment,consisting of 15 normalized indexes of the indoor air by means of the gauge symmetry principle.Based on the aforementioned study of the formulae,we have applied them to the air quality assessment practice of the indoor air for the two cases of the residential areas in Handan,Hebei,as well as for the public places of Guangzhou City,Guangdong,in hoping to test the practical effectiveness of the 6 index formulae.And,the assessment results of the aforementioned 6 universal index formulae for the 2 cases prove to be well in accord with the results assessed by using the traditional methods and consistent with each other.Thus,it can be concluded that the 6 index formulae can be taken as the up-to-date most convenient and regularized means for air quality assessment both for the indoor and outdoor air conditions at least at home.
