| 中文摘要: |
| 在小型混流式水泵水轮机模型装置上对转轮流道的压力分布进行了实测，并通过流动可视化摄制了翼间流动的图像；由实验与图像处理结果获得了“S”特性区的真实流态，讨论了“S”特性区不稳定流动的原因。 |
| 英文摘要: |
| The pressure distributions of the Francis pump-turbine runner are measured in model test and the flow is visualized by using tracer method.The flow patterns are analyzed according to the receorded video pictures.The unstable flow in S-shape characteristic region is discussed. |
