本文介绍了作者在分粒径组推移质输沙率方面所作的广泛试验。对这些资料以及来自其他方面的可用资料进行了分析。这些资料涉及的水流条件和泥沙的不均匀性范围很广，因而具有较好的代表性。首先对由Misri等人1984年提出的半理论模型加以改进，继而发展为一种推移质计算方法，最 This article presents an extensive review of the authors’ work on sediment transport rates in sub-grading groups. The data as well as available information from other sources were analyzed. These data cover a wide range of flow conditions and sediment inhomogeneities and are therefore well represented. Firstly, the semi-theoretical model proposed by Misri et al. In 1984 was improved, and then developed into a method of calculating bed mass
