摘要
本文依据概率论原理，通过建立条件频率曲线的方法，论证了推悬比的频率曲线，即悬移质发生的条件，相应推移质的条件频率曲线。以长江新厂站实测资料为例，对如何建立推悬比的频率曲线的工作程序、方法、图表等，作了详细说明。为泥沙工程中确定推移量、延长推移质系列、改进泥沙测验布局，提供了一个新方法。
Based on probability theory, the paper proved that y/x frequency curve, y is bed load transport rate and x is suspended sediment discharge, is the corresponding conditional frequency curve of bed load transport rate when suspended sediment appeares.With field data of Xinchang station, the program, figures and tables of y/x frequency have been illustrated, and a new method has been provided for determining the bed load transport rate, extending the data of bed load, improving the distribution of sediment measurement.
