| 摘 要： | 用下临界Ｒｅｙｎｏｌｄｓ数、上临界Ｒｅｙｎｏｌｄｓ数、临界Ｆｒｏｕｄｅ数将明渠水流的流态划分为六区，即：缓层流、缓过渡流、缓紊流、急层流、急过渡流、急紊流，提出了六区流态划分图。并对明渠流与管流采用统一的流速公式问题，提出了看法。

| Abstract: | Based on the subcritical Reynods number, supercritical Reynolds number and critical Froude number, open-channel flow is divided into six regimes, i.e.tranquil laminar flow, tranquil transitive flow, tranquil turbulent now, rapid laminar flow, rapid transitive flow and rapid turbulent flow, A divisional diagram of flow regimes is given. In addition,the author also gives his view on using a unified velocity formula for open-channel flow and pipe now. |
