摘要：

We consider three-dimensional flows of an inviscid (or asymptotically inviscid), incompressible fluid and present a method for describing the propagation of nonlinear small amplitude, short wavelength perturbations of these flows. Analyzing the evolution of these perturbations we obtain a local sufficient condition for the nonlinear instability of an arbitrary three-dimensional flow.
