摘　　要： 增压式水机磨蚀试验台较其它试验装置更为逼真地模拟了水轮机水流状态.其特点在于试验转轮体叶片即为试件,试验介质为黄河天然含沙水并能在短时期内出成果.本文论述了利用该装置所取得的一些试验成果,探讨了含沙水流下不同材料磨蚀形状的成因.The flow pattern in the hydraulic turbine can be simulated more actually on the boaster-type hydraulic abrasion rig than on the others. It has the following features: the runner blades themselves are the samples, the test medium is the original silt-laden water from the river course of Yellow River and the test period is short. Experimetal results obtained on this rig are described and the formation causes of various cavitation erosion patterns for different materials in silt-laden flow are discussed in this paper.
