摘要：

A transfer-matrix version of a mean-field approximation is proposed which leads to the exact critical temperatures for the S=1/2 Ising model on the square, triangular, honeycomb, and centered square lattices. The estimations of critical temperatures for more complicated models are also shown to be very accurate.
