Enhancement of the K -->pi Transition by the Instantaneous Weak Interactions

.Z.D .N The hadrodynam icsofthe instantaneous weak interactions (IW I)in Standard M odel is considered supposing the resonance nature ofthe chiralhadronization ofquark currents in Q CD .Exploiting this supposition and Q CD sym m etries the IW Im echanism of enhancem entofthe K !
