摘要：

Phase transitions in the two-dimensional slightly diluted Potts model on a square lattice atq= 5 have been studied using the computer simulation method. The systems with linear sizesLxL=N,L= 10-120 are considered. It is shown based on the forth-order Binder cumulants and using the histogram analysis of the data that the introduction of nonmagnetic impurities to a spin system described by the two-dimensional Potts model withq= 5 leads to a change of the first-order phase transition to a second-order phase transition.
