  We study the chiral phase transition of the two-flavor Nambu-Jona-Lasinio
(NJL) model in a rotating sphere, which includes both rotation and finite size
effects. We find that rotation leads to a suppression of the chiral condensate
at a finite temperature, while its effects are smaller than the finite size
effects. Our work can be helpful to study the effects relevant to rotation in
heavy-ion collisions in a more realistic way.
