水躍消能工的研究Uning the experimental data, the dec r eased percentages of conjugate depth, length of hydraulic jump or unit width hydr a ulic jump volume with the increased dissipated energy facilities are calculated
並通過模型試驗驗證了消能的理論分析，計算了新增設施的消能量、躍后水深、水躍長度或單寬水躍容積減少的百分數。However, because of the particularity that is hydraulic jump, before jumping, when water ' s froude number is less than four point five, the damping ratio is so low that energy dissipator ' s lower river produce serious flushing, so much so that it may threaten energy dissipation structure ' s safty
然而，因為水躍本身又具有其特殊性，在躍前水流佛汝德數（ froudenumber ）小於4 . 5時，消能率很低，致使消能工下游產生嚴重的沖刷，甚至危及消能建築物本身的安全。The economic benefits of new additional energy dissipation facilities are estimated in terms of the decreased percentage of the sequent depth of hydraulic jump and length of jump, or the capacity of hydraulic jump under the unit width. the additional flow hydraulic jump theory has been demonstrated by model tests
