摘要：
The series expansion of the local approach to investigate electron correlation has been extended to the periodic Anderson lattice. The results show that corrections of the correlation energy \E(c)\, local moment, ground state energy and the charge fluctuation of the third-order perturbation results are significant over the second-order perturbation.
