Abstract
The phenomena of underwater explosion are so complex that the description of similarity laws seen simple,general and indistinct in literature.In this paper,some generally recognized similar laws for the shock wave of underwater explosion were explained,in order to show that there is no alternative choice.The similarity of bubble pulsing for tests of underwater explosion was derived,and the scaling laws for underwater explosion in free fluid field were connected to the structure similarity.
