摘要：
The quenched site-diluted Ising model on a two-dimensional square lattice is studied by employing the mean field renormalization group approach. The critical temperature as a function of the concentration is obtained and compared to other different types of approximation. Quite good results are achieved even by considering relatively small clusters.
