摘要
以维利坎诺夫含沙量分布公式为据，从理论上导出其相应的悬沙级配Ｐｉ分布式，且给出Ｐｉ／Ｐ０ｉ、Ｐｉ／Ｐｉｐｊ及Ｐｉ／ＰｉｐｊＱ三种表达形式．悬沙级配沿垂线分布概念的产生及其理论公式的导出，有助于深化悬移质运动机理的认识。
According to the Velikanov formula of the vertical distribution of sediment concentration,the three kinds of expressions for the vertical distribution of the grain composition of suspended sediment, P i/P oi ,P i/P i pj and P i/P i pj Q ,are derived.It is helpful to study the law of the suspended load movement and to correct the error for the observed data of the suspended sediment composition in field.
