摘要：

The two-dimensional Ising model decorated with Ising spins of magnitudes s = 1 and 1/2 is considered. The bonds are randomly decorated with n spins and the random variable is supposed to satisfy an annealed distribution. The model is exactly solved by mapping it onto an effective 2D Ising model. The phase diagram is determined and the lim n --> infinity is discussed.
