摘      要：The Metropolis Monte Carlo algorithm is applied to a classical O(2)model on nice tree and Bethe ***-size scaling theory is applied to estimate the critical *** results show that the continuous symmetry may not be spontaneously broken even if d_(f)≥d_(w)+1 where df and dw are the fractal dimension and the dimension of the random walk on the structure respectively or even if the random walk on the structure is transient.
