摘要：

A Monte Carlo study of the two-dimensional randomly site-diluted Ising system is reported. The data reveal that the specific heat does not diverge at the critical point, at least when the concentration of dilution is sufficiently large. The critical behavior of the magnetic susceptibility and the correlation length are consistent with pure power-law behavior with concentration-dependent critical indices.
