摘　　要：根据黄河实际资料,考虑泥沙粒配(包括粒径、细颗粒含量及不均匀系数等)对极限浓度的影响,建立了极限浓度的经验表达式以及粘度的计算公式,验证结果肯定了所获公式的精度及实用性。Of all factors which effect the limiting concentration of the flow with sediment, the graduation of particles is the most important one. The influence of the diameter and the concentration of fine particles could be reflected by the specific surface area of sediment and by the non-uniformity coefficient. Based on the measured data from the main stem and the tributaries of the Yellow River, an empirical formula of limiting comcentration has been established. Furthermore, a calculating formula for viscosity for the flow of the Yellow River has been established and proved practically and precisely.
