<P>Super sound wave takes implosion effect on fluid,namely,</P>
<P>micro voids are formed in liquid by wave inflation and compression.</P>
<P>The air and steam in these voids take positive pressure effect on</P>
<P>liquid molecule in compression period while take negative pressure</P>
<P>effect in inflation period .Cohesion exists in the liquid or biological</P>
<P>tissue,the cohesive force is strong under low density in fat cells,</P>
<P>and the low negative pressure can generate inter-space,physically </P>
<P>called "cavitation".The implosion can enhance the molecular motion</P>
<P>to a high level,then result in rupture of fat cells.</P>
