摘　　要：本文将Yoshimori-Kasai模型的 Slave-boson平均场理论推广到Nambu空间,求出了重费密子超导态的格林函数,研究了 d-波配对的重费密子超导体对非磁杂质的强敏感行为,所得结果与实验更加符合.In the present article,the use of the slave-boson mean field theory of the Yoshimori-Kasai model has been generalized to the Nambu space.The Green's functions of the heavy-fermion superconductors (HFS) have been obtained.The strong sensitivity of the d-wave pairing HFS to the non-magnetic impurities has been studied.The results obtained are in better agreement with the experiments in HFS.
