利用动量原理研究了两层流体系统流动的共轭态数。证明了当任一层的修正弗劳德数占主导地位时，共轭态的唯一性。三种特殊情况下的具体试验结果证明了水跃下游状态的唯一性，并表明，对于一次近似，简单的分析提供了一种确定下游深度的方法，对于较低的跳跃，误差较小。DOI：10.1111/j.2153-3490.1955.tb01172.x
The number of conjugate states for the flow of a fluid system of two layers is investigated by means of the momentum principle. The uniqueness of the conjugate state is proved for the cases in which the modified Froude number for either layer is predominantly large. Specific experimental results for three special cases demonstrate the uniqueness of the state downstream from the hydraulic jump, and show that, for a first approximation, the simple analysis provides a means for determining the downstream depths, with smaller errors for lower jumps.
