| 摘 要： | 讨论了无限大小域中考察液体压缩性影响下空泡溃灭冲击波对固体颗粒的作用，求得了固体颗粒所获得的最大速度，当满足一定条件时，固体颗粒运动速度值之高足以打坏现有水工建筑物所用的混凝土，引起固壁的大面积剥落，形成空蚀，冲击和磨蚀的恶性循环。

| Abstract: | The impact of shock waves of the bubble collapse on the solid particles is discussed by takinginto account liquid compressibility in the unbounded liquid to obtain the maximum velocities of solid particles. When some conditions are satisfied , the speed of particles induced by the shockwaves is great enough to destroy the concretes now used in hydrauilic structures. Furthermore,agreat quantity of solid walls might be peeled off to cause serious iteration of cavitation erosion,wear and impact. |
