摘　　要：本文根据流体动力学的流体流阻定律，对三种规格的碗形喷嘴试验数据进行分析研究，找出了预测喷嘴工作压强（Ｐ）与喷射流量（Ｑ）关系的两种方法。同时也给出了喷射角（β）和水力效率的计算公式。另外，对改进喷嘴结构提出了初步设想。According to the resistance law of hydrokinetics, the two methods of predicting relational factor are found as related to the nozzle of the pressure(P) and the flow quantity(Q)basing on the research of teSting data of three bowl-shaped nozzles, Simultaneously, the calculating formulae have heen decided on the jet angle (β)and the hydraulic efficiency(ηh). It is sugg in broad outline that the improvement of the nozzle stnrcture.
