为了讨论重费米子系统的正常态性质，在具有任意自旋轨道耦合和晶体场的周期性安德森模型的基础上发展了费米液体理论。对于未受扰动（U=0）的情况，电子能带结构是确定的；然后推导了比热和磁化率的T线性系数：mt的表达式。当U=1=0时，推导了T-lineGlr比热系数和磁化系数的一般表达式。然而，由于 I 电子自能的非对角元素的存在，磁化率的表达式通常不能采用仅包含费米面上的量的通常形式。因此，磁化率是在仅考虑最低克莱默双峰的特殊情况下计算的。
In order to discuSs the normal-state properties of heavy-fermion systems, the Fermi liquid theory is developed on the basis of the periodic Anderson model with arbitrary spin-orbit coupling and crystalline field. For the unperturbed (U =0) case, the electronic band structure is determined; then the expressions of T-linear coefficif:mt of specific heat and magnetic susceptibility are derived. For U =1= 0, the general expressions for T -lineGlr coefficient of specific heat and magnetization are derived. However, the expression for magnetic susceptibility cannot generally be brought into such a usual form that includes only the quantities on the Fermi surface because of the existence of off-diagonal elements of I-electron self-energy. Therefore, the susceptibility is calculated in the special case that only the lowest Kramers doublet is taken into account.
