Abstract: In this paper, a SU(2)×SU(2) chiral model on 2-dimensional random lattice is studied by Monte Carlo simulation with 8×8, 9×9 and 10×10 lattice volumes. The results of its energy and specific heat per link are obtained and coincide with that of SU(2) gauge system on 4-dimension. The systems enter crossover region at β1.0 but show no obvious evidences of continuous phase transition. Thus we believed that the correspondences between 4-dimensional SU(N) gauge theory and 2-dimensional SU(N)×SU(N) spin system may be generized to interesting random lattice.
