Self-purification curves are presented, percentages and rate constants of the purification are calculated, and influence of temperature, flowrate, and turbidity on self-purification are discussed.
绘制了自净曲线，计算了自净百分率和自净速率常数，并讨论了温度、河水流速及浊度对自净作用的影响。

According to the calculated result and experimental data, this flowrate distribution is mainly caused by the influence of the curvature of streamline on the flow field.
结合计算结果与实验结果认为，流线弯曲程度对流动的影响是产生这种流量分布趋势的原因。
