摘要翻译：
我们用大数定律计算了无序urn模型的自由能。结果表明，用大数定律得到的鞍点方程与用复制法得到的鞍点方程是相同的。因此，我们得出结论，对于无序的urn模型，复制对称解是足够的。此外，我们还指出了urn模型与随机场Ising模型自由能的数学相似性；这种相似性证明了urn模型的复制对称解是精确的。

英文摘要：
We calculate the free energy of the disordered urn model using the law of large numbers. It is revealed that the saddle point equation obtained by the usage of the law of large numbers is the same as that obtained by the replica method. Hence, we conclude that the replica symmetric solution is adequate for the disordered urn model. Furthermore, we point out the mathematical similarity of free energies between the urn models and the Random Field Ising Model; this similarity gives an evidence that the replica symmetric solution of the urn models is exact.
