• By means of the Fourier transform, an amplitude expansion and a wave-number expansion, the Navie?"-Stokes equation is reduced to a weakly nonlinearequation for the slowly varying complex amplitude of an envelope of a quasi-monochromatic and weakly three-dimensional disturbance. The reduced equationfor the amplitude discloses severe condition of justification of the nonlinearSchr6dinger type equation. The weak three-dimensionality of disturbance aswell as the weak nonperiodicity has significant effects on the instability of planePoiseuille flow.
