%X The dynamics of a single high-speed bubble impacting with a solid target are simulated by MSC.Dytran The relations between the damage depth or damage width and the initial pressure,velocity,the incident angle of bubbles and drips,and the thickness of target,are presented in curves,and the physical mechanism is discussed. The theory of water jet impacting rock is also discussed.
