摘要：
Experiments have found that freely relaxing turbulence in inviscid, incompressible two-dimensional Euler flows can self-organize into ordered structures-vortex crystals-in which a number N-c similar to 2-20 of strong Vortices form stable; rigidly rotating patterns in a low vorticity background. Ln this paper we show that N-c can be roughly predicted from properties of the flows in the early stage of the turbulent relaxation.
