| 中文摘要: |
| 本文通过引入密度变化率ε，给出了异重流和均质明渠流之间的一些相似关系，将分层流基本方程、微波流速、急缓流判别、内水跃共轭水深、分层取水流量等给出了在形式上与均质流体对应公式一致的计算公式，使分层流算式变得简单明确，便于应用。本文最后还给出了一些计算实例。 |
| 英文摘要: |
| The similarity relationships between density flow and uniform flow in open channel are established by introducing the density difference rate into the basic equation, equation of microwave velocity, formula for discriminating the super critical flow and equation for determining the conjugate depths of internal hydraulic jump for density flow. These equations have the same forms as the corresponding equations for uniform flow. So that, their concepts are simple and can be easily used. Some examples are given. |
