| 摘 要： | 针对过去床沙粗化实验中依据推移质输沙量确定粗化稳定的不足，利用分维测度提出了两种新的判别方法，即通过计算分析粗化层及推移质级配分维值稳定程度而加以识别。通过实验资料计算验证，得到了较满意的结果，对研究泥沙级配特性及粗化稳定具有积极指导意义。

| Abstract: | Aiming at the faulty in determing coarsening stability by means of bed load transport rate during the bed material armoring experiments in the past,two new recognition methods are proposed by using the fractal theory,i.e.,by analysing the stable degree of fractal dimension of bed load size distribution and calculating coarsening layers.After verification by experimental data,the results are satisfactory, and it is of important significance for studying on the characteristics of sediment size distribution and stability of coarsening. |
