摘要：

We derive low-temperature expansions of the internal energy, the specific heat and so on for the antiferromagnetic Ising model on a triangular lattice by using the expression obtained by Stephenson. We propose to use DELTA-T = exp (-2-beta-J) as the reduced temperature variable near the critical temperature. We then conclude the values of the critical exponents-alpha, nu, gamma, delta and DELTA as alpha = 0, nu = 1, gamma = 3/2, delta = 7 and DELTA = 7/4.
