本文报道了用蒙特卡罗方法研究二维随机位置稀释的伊辛系统。数据表明，至少在稀释浓度足够大的情况下，比热在临界点不发散。磁化率和关联长度的临界行为与浓度相关的纯幂函数行为一致。
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.
