| 摘 要： | 本文讨论了H.Rouse泥沙浓度分布公式的数学性质.在此基础上,将悬浮指数z<1的泥沙定义为细沙;将z≥1的泥沙定义为粗沙。本文推导了粗沙情况下床沙质输沙率的解析计算公式,经与数值结果比较,表明本文的推导是正确的。

| Abstract: | The mathematical characteristics and physical explanation of Rouses equation for the suspended sediment concentration distribution have been discussed. Based on this, the sediments for suspended index Z< 1 and z≥1 are defined as fine and coarse grains respectively. Then, the analytical solution of Einstein total load equation for coarse grains is derived. Compared with numerical results, it shows that the derivation is correct. |
