摘要
本文根据动量定理及上下游水流总能量守恒提出了一种新的表、中孔水舌空中碰撞消能率的计算方法，所给公式概念清楚，较真实地反映了工程实际，并结合模型试验给出了一个算例。
According momentum theory and total energy conservation of water jets, theauthor bring forth a new method to compute energy dissipation ratio of water jets impact inair in this paper. The formula given is clear in concept. It truly reflects project reality truely. A computing example is given combined with model experiment.
