摘要翻译：
用Monte Carlo方法研究了无序铁磁Ising模型在非磁性杂质原子浓度变化范围内的临界行为。测定了不同自旋浓度和不同线性尺寸样品的相关长度和磁化率的温度依赖性。利用有限尺度标度技术获得这些量的标度函数，这些量在临界区表现出普遍的行为；临界温度和静态临界指数也用标度修正来确定。根据标度函数和临界指数值随浓度的变化，得出了弱无序和强无序体系的稀释Ising模型存在两类具有不同性质的普遍临界行为的结论。

英文摘要：
  The critical behavior of the disordered ferromagnetic Ising model is studied numerically by the Monte Carlo method in a wide range of variation of concentration of nonmagnetic impurity atoms. The temperature dependences of correlation length and magnetic susceptibility are determined for samples with various spin concentrations and various linear sizes. The finite-size scaling technique is used for obtaining scaling functions for these quantities, which exhibit a universal behavior in the critical region; the critical temperatures and static critical exponents are also determined using scaling corrections. On the basis of variation of the scaling functions and values of critical exponents upon a change in the concentration, the conclusion is drawn concerning the existence of two universal classes of the critical behavior of the diluted Ising model with different characteristics for weakly and strongly disordered systems.
