在磁场和晶场存在的情况下，基于Bethe-Anglesian方法，得到了高关联简并安德森模型的平衡热力学方程.在低温下对这些方程进行了解析处理，得到了比热的一般表达式，它反映了费米液体的性质。作为一个简单的例子，将本理论应用于立方晶场中Ce杂质的情况。本文的方法也适用于存在自旋-轨道耦合的情况。
The equilibrium thermodynamic equations for the highly correlated degenerate Anderson model are obtained on the basis of the Bethe-Ansatz method, in the presence of the magnetic field and the crystal field. These equations are treated analytically at low temperatures and the general expression for the specific heat is obtained, which shows the Fermi-liquid properties. As a simple example, the present theory is applied to the case of the Ce impurities in a cubic crystal field. The present formalism is also applicable to the case where the spin-orbit coupling exists.
