摘要
本文定性分析了连续排放污染物于均匀平直河流中的扩散过程，并对其划分出三个混合阶段，分别给出相应的水质模式，并重点描述了横向混合阶段所预测的主要内容，并根据预测断面所处的混合阶段，提出水质模式的选择方法。
By analysing qualitatively the diffusion process of the pollutants dsscharged into uniform and straight rivers,and dividing the process into three mixing zones, giving the corresponding models of water quality,and describling mainly the main predicted contents in the crosswise mixing zone Finally,we conclude the selection method of water quality model according to the predicted sections located in the mixing zones in this artide
