摘要
以流量和含沙量在时段内呈线性变化，而输沙率应是二次函数为出发点，用积分的方法推导出时段平均输沙率的计算公式。认为采用这套公式计算日平均输沙率和日平均小于某粒径沙重百分数是合理和实用的，可以提高成果的准确性。
This parer uses integration to deduce a set of formulas of calculating time-average sedimentdischarge based on that the changes of discharge and sediment concentration are linear but the change of sedimentdischarge is quadratic. It is considered in this pater that it is reasonable and practical to use this set of formulasin calculating daily average sediment discharge and daily average percentage of sedimient smaller than a certaingrain diameter, which can improve the accuracy of the result.
