摘要：

The mean-field approximation of the one-dimensional ferromagnetic p-state Potts model with interactions decaying as a power law is developed using a modified Bethe lattice recently introduced. it is shown that the transition is of second order (first order) for p less-than-or-equal-to 2 (p > 2). The critical behavior is also presented.
