| 摘 要： | 通过建立和求解一个地区饮水水溶液模型可获得标准致病水与非致病水的各种化学组份活度。使用以所有水溶组份活度为变量的多元逐步判别分析,确定出临界致病因子,能有效地进行水质判别。通过对某氟中毒地区饮水实例研究表明,临界致病因子分析法是成功的,并经对水中总氟浓度按照临界致病因子的分解,发现总氟浓度在一定区间内无法用来判别水质。这一区间的存在说明,为什么制定适宜的饮水总氟浓度标准是困难的。

| Abstract: | The activities of various chemical compositions of the standard pathogenic water and non - pathogenic water in a region can be estimated through establishing and solving the groundwater aqueous model. Using the stepwise multiple discriminant analysis with all the aqueou compositions as the variables , the author determined the critical pathogenic factors (CPF)used to distinguish water quality. In addition, the total concentration of the fluorides (TCF) in the water can be disintegrated according to CPF. We have found that within certain scope of concentration, TCF is useless to distinguish water quality. The presence of the scope shows why setting a suitable TCF of water for drinking is always difficult. |
