This work focuses on the evolution behaviors of ring dark solitons(RDSs)and the following vortices after the collapses of RDSs in spin-1 Bose-Einstein condensates.We find that the weighted average of the initial depths of three components determines the number and motion trajectories of vortex dipoles.For the weighted average of the initial depths below the critical depth,two vortex dipoles form and start moving along the horizontal axis.For the weighted average depth above the critical depth,two or four vortex dipoles form,and all start moving along the vertical axis.For the RDS with weighted average depth at exactly the critical point,four vortex dipoles form,half of the vortex dipoles initiate movement vertically,and the other half initiate movement horizontally.Our conclusion is applicable to the two-component system studied in earlier research,indicating its universality.
