| 摘 要： | 分析了平底坡情况下两层不同密度的异重流,上层静止下层流动或上层流动下层静止时的内水跃与明渠均质流动中的水跃之间的相似关系.在此基础上,从明渠一维渐变流公式和异重流运动方程导出了明渠渐变流水面曲线与两层异重流交面曲线之间的相似关系.通过实例验证了本文的论述.

| Abstract: | The similarity between hydraulic jump occurred in horizontal open channel flow and internal hydraulic jump happened to stratified flow with still upper layer and flowing lower layer or flowing upper layer and still lower layer is analyzed theoretically. On this basis, the similarity relationships between the water surface curve of gradually varied open channel flow and form of interface profile in stratified flow is deduced from the formula of 1 D gradually varied flow and basic equation of stratified flow. The validity of the relationship is verified by examples. |
