| 摘 要： | 孙成宝等人用主成分分析与全局主成分分析的方法研究了沈阳、广州、桂林等七座城市环境空气质量,得到了一些有价值的结论,但考虑的污染因子太多,将对测量数据、处理数据等带来很多不便。本文用逐步判别法克服了这一不足,将该文的6个污染因子减少到3个,然后对这7座城市环境空气质量进行评价,得到了与孙成宝等相吻合的结论。

| Abstract: | Using the principal components analysis and global principal components analysis the ambient air quality of Shenyang,Guangzhou,Guilin et al seven cities is researched by Sun Chengbao et al and some valuable results are obtained,but the authors have considered much more contaminated variables,which would make many troubles in measuring and dealing with data.In this paper,we overcome the disadvantage by stepwise discriminatory method,that is,variables are reduced from seven to three.And then we evaluate the environmental air quality in the seven city,obtain some results which are consistent with those of Sun Chengbao et al. |
