比较选用能较适用于该河段的推移质输沙率公式，计算出各断面的推移质输沙量，得出推移质输沙量与流量的关系曲线。
An appropriate formula of bed load rate is chosen to calculate the amount of bed load of each section. Curves of amount of bed load and discharge are got.
提出了一种计算推移质输沙率的方法及公式，该公式表明，在水流强度一定时，输沙率并非为一个常量，而是随颗粒在床面的相对暴露度而变。
The formula shows the transport rate is not a constant but varies with the relative exposure degree of particles that lying on riverbed when the flow intensity is at fixed value.
在水流很强时，爱因斯坦公式所给出的推移质输沙率有可能偏小。
When the flow intensity is high, the transport rate of bed load as given by Einstein formula might be too small.
