| 摘 要： | 根据紊流扩散理论所得的三维非恒定悬移质泥沙运动方程，利用相似理论，对悬移质泥沙悬移相似条件进行了初步探讨，结果表明，悬浮相似条件和沉降相似条件相同。众多学者之所以推导出与此条件不相容的悬浮相似条件，问题的关键在于泥沙紊动扩散系数比尺αεSy 的求解中，引用了摩阻流速、对数流速分布和卡门 常数比尺这3个在变态模型中互不相容的等式条件。

| Abstract: | According to the three-dimension unsteady suspended sediment transport equation achieved by turbulent diffusion theory,and by using similarity theory,the similar conditions of suspended sediment transport are discussed preliminarily.The result indicates that the similar condition of settlement is the same as that of suspension.Many investigators have derived different suspension similar conditions which are incompatible with above mentioned condition,of which the key reason is that,in resolving the sediment... |
