This paper describes characteristic features of flow patterns that were experimentally analyzed in the transision region of the two dimensional parallel jet with parabolic velocity distribution. The asymmetrical vortex street or symmetrical vortex street was observed in the jet of water shot out from the slot into two dimensional flow field. There were the asymmetrical voltex street at low Reynolds number, and symmetrical voltex street at hight Reynolds number determind by the width 2b of slot and the jet velocity U at slot. These results fitted the linear approximation mathmatical model by Euler's kinetic equation and continuity equation.
