摘要：
A generalized Mermin-Ho relation for a spin-1 Bose-Einstein condensate is derived, which is applicable to vortices regardless of the symmetry and spin polarization of the order parameter. The obtained relation implies an su(3) mass-current circulation and two classes of vortices corresponding to two different su(2) subalgebras.
