| 摘 要： | 本文深入研究了非均匀悬移质不平衡输沙的内在机理，较严格的推导了其方程，引进和定义了水量百分数、悬移质级配、平均沉速。根据泥沙交换强度理论，专门研究了方程的底部边界条件，在一定简化下给出了底部边界条件的具体表达式及有关结果，并与以往经验数据基本符合。

| Abstract: | Based on the research in the mechanism of nonequilibrium transportation of nonuniform suspended load,the diffusion equation is derived.The concept of percentage of water volume is introduced and the size distribution and average terminal velocity of suspended load are defined.According to the theory of exchange intensity proposed by the authors the boundary conditions at the bottom is studied and their simplified expressions and related coefficients are derived.The coefficients calculated from the introduced expressions are fairly agree with the existing empirical coefficients. |

| Keywords: | nonuniform suspended load boundary condition percentage of water volume related coefficients suspended probability ceasing probability. |
