摘　　要：该文综合介绍了近几年黄河下游调水调沙期间出现的洪峰异常增值现象及其发生的水动力学机理、概念验证及与其紧密相关的极细沙减阻和水槽试验研究成果,并介绍了黄河水利科学研究院利用"多沙河流洪水演进与冲淤演变数学模型"对洪峰增值实际过程的验证及预报情况等。对于泥沙减阻力学及减阻效应方面的研究任重而道远,该文旨在抛砖引玉,借此希望更多的学者能够关注这一问题的研究。The phenomenon of flood＇s peak increase has occurred many times in the lower Yellow River. However, the phenomenon which appeared during the regulation of the water and sediment in recent years has been concerned widely, and this phenomenon for Yellow River water-sediment regulation has brought great risk and stress. This paper introduced thephenomenon in recent years and its dynamic mechanism such as it happen concept verification, its closely related concept of friction reduction and some experimental result of extremely fine sand flume tests. The paper also introduced the practical process of this phenomenon validation and forecast situation based on the numerical models of flood routing and morphological changes in sediment-laden. The purpose of this paper was to hope to get more people concerned about the research of the phenomenon and roughness reduction.
