通过模型试验测量了弗朗西斯水泵涡轮机转轮内的压力分布，并采用示踪剂法对转轮内的流动进行了可视化，根据记录的视频图像对转轮内的流态进行了分析，讨论了S形特征区的不稳定流动。
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.
