摘要:Based on the conception "pseudo-potential" of incompressible flow in the plane, we give an exact solution of the pseudo-potential flow to the Euler's equation with arbitrarily external potential force. This solution describes infinitely many unsteady vortexes distributed periodically on the whole plane and the Brownian motion appeared in the neighborhood of the edge between these vertexes.
