摘要：
By direct numerical simulation of the Navier-Stokes equations we investigate the reconnection of two antiparallel vortex tubes. A new type of perturbation of the initial vorticity field is given which is different; from that presented in Refs.[8] and [9]. The formation and the evolution of the ''curved vortex belts'', their mutual action with the ''bridges'' are found. These are important phenomena not studied by others.
