主　　题：cavitation erosion orifice bubble dynamics 

摘      要：Serial grades of cement mortar specimens have been tested on the model of con- crete-lining flood discharge tunnel with orifice,The results show that incipient cavitation erosion number is much smaller than incipient cavitation *** on the principle of bubble dy- namics,the flow speed effect on incipient cavitation erosion number for cement mortar is pre- sented.
