从误差传播及经验关系分析两条途径出发，分别获得了流量输沙率关系不确定度。通过F检验，证明了所获成果的可靠性。本文分析对于流量输沙率关系不确定度控制指标的确定，以及流量输沙率关系的应用具有实际意义。
Based on the two approaches of error propagation and empirical relationship analysis, the uncertainty of the relation between discharge and sediment transport rate was obtained respectively. Through the F test, the reliability of the obtained results is proved. The analysis of this paper is of practical significance for the determination of the control index of the relationship between the rate of sediment transport and the relationship between the rate of sediment transport and the rate of sediment transport.
