摘要：

The two-dimensional random Ising ferromagnet is investigated numerically by the Monte Carlo method. The integrated distribution function of magnetization is calculated above and below the Griffiths temperature which corresponds to the critical temperature of the pure system with smaller interaction. It is found that this function shows different behavior above or below this temperature.
