摘要
从悬移质运动剖面二维扩散方程出发 ,通过适当假定 ,获得了饱和含沙量垂线分布公式、悬移质运动一维质量守恒方程和剖面二维实用型方程 ;重新定义了“α系数” ,给出了理论计算公式 。
Based on the profile two dimensional dispersion equation of suspended load movement,vertical distribution formulas of saturation sediment content,one dimensional mass conservation equations of suspended load movement and profile two-dimensional practical equations are deduced by proper assumption.Then,“α coefficient”is redefined and theoretical calculation formulas are given.Finally,the uniqueness of carrying capacity is described.
