应用该方法可定量地描述COD浓度在时间和空间上的分布状态，进行水质污染预报和评价。
This method can be used to describe the time and spacial distribution states of COD concentration for carrying out the prediction and assessment of water pollution.
浓度同气象条件关系密切，本文采用一元统计方法对二者进行相关性分析，从而得到对PM_（10）污染影响显著的气象要素，作为后续进行PM_（10）浓度预报的依据。
There is a close correlativity between PM_(10) concentration and meteorological condition, so one-member statistical method had been used to analyst the correlation between them according to season.
