本文利用正则变换将稀释合金中局域磁矩的安德森模型与近藤模型联系起来。在小的s-d混合的限制下，这是最有利的情况下发生的时刻，这两个模型被证明是等价的。因此，安德森模型的低温异常类似于前面讨论的近藤模型。
A canonical transformation is used to relate the Anderson model of a localized magnetic moment in a dilute alloy to that of Kondo. In the limit of small s− d mixing, which is the most favorable case for the occurrence of a moment, the two models are shown to be equivalent. The Anderson model thus has low-temperature anomalies similar to those previously discussed for the Kondo model.
