摘要

利用坡面薄层水流的电解质脉冲数学模型

计算了不同坡度和含沙量下的电解质弥散系数

发现在泥沙含量较低时

弥散系数与水流速度有较好的线性相关性

但泥沙含量较高时

泥沙含量对弥散系数作用更加强烈

弥散系数与速度的相关性较差

说明弥散系数受泥沙含量和水流速度影响

但三者的关系函数有待于进一步探讨。

Abstract

The dispersion coefficients of electrolyte solute in flow of different slope and sediment concentration are calculated using the mathematical model of electrolyte pulse transferring in laminar flow. The dispersion coefficient is liner related to the velocity of flow when the sediment concentration is relatively low; The sediment concentration is high

it affects intensively the dispersion coefficient

and make their liner relationship bad. These results shows that the relation between dispersion coefficient and sediment concentration and velocity deserves to more discuss.
