【摘要】 在对饮水致病的水化学机理进行简要讨论后，提出使用以所有水溶组分活度为变量的多元逐步判别分析法作为饮水水质标准的确定方法。经对一个地区的实例研究发现，总氟含量用于判别水质时存在无效判别区间问题，这一发现提示我们有必要重新考虑现行水质标准中总氟浓度只有一个标准值的适宜性问题。更多还原

【Abstract】 In this paper,after discussing the water chemistry principle for sick from drinking water,the author suggests that the stepwise multiple discriminant analysis with all the aqueous compositions as statistical variables should be used to establish the water quality standard of drinking water.Having studied an area as an example,the author discovers that there is a scope of the total fluoride concentration suitable for distinguishing the water quality;and it is necessary to reconsider the adaptability of present water quality standard.更多还原
