摘　　要：为了加深学生对水力学中能量方程的理解,针对恒定渐变流能量方程中总水头线和测压管水头线变化规律、均匀流过水断面和急变流过水断面动水压强分布规律、紊流状态下管道断面平均流速和断面中心点流速规律,进行了设点实测和数据分析,提高了教学实效。The change trend of total head line and piezometer tube water head line in tube,hydrodynamic pressure on cross section of gradient flow and rapidly varied flow,and the relationship between the average flow speed and centre speed of cross section in turbulent tube flow were obtained by analyzing the data sampled from the instrument of energy equation.The detailed analysis and discussion for experimental data were operated.

关 键 词：水力学 能量方程 测压管水头 流速规律
