摘　　要：在定义管道内水跃的消能系数为水跃单位能量损失与跃前断面水流原有单位能量的比值的基础上,推导出计算消能系数的基本公式,并分析了它的规律性。可供学者或旨在应用管道内水跃消能的工程设计者参考使用。On the basis of defining energy dissipation ratio in a closed circular conduit as specific energy loss of hydraulic jump divided by specific energy of initial flow,this paper derives a basic equation for calculating this energy dissipation ratio and describes its characteristic.It can be used as a reference for researchers or designers.

关 键 词：圆断面水平管道 水跃 消能系数
