陈春先 %A 陈式刚 %A 霍裕平 %J 物理学报 %D 1960 %I %X Using the generalized method of self-consistent field developed by one of the authors4], we discuss various correlation phenomena of many-body systems with a unified viewpoint. The general method of treatment is proposed and compared with the method of perturbation. From the approximation with two-body correlation we obtain, as particular applications, the Bruckner theory of nuclear matter and the Bohm-Pines theory of the collective oscillation of electron,gases. Finally the superconductivity and zero-point oscillations in non-ideal gases are discussed by solving, the bound state problem with the present method and the Gell-mann Low procedure. It is concluded that the method is very effective in treating correlation phenomena. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=F01476F0EC34F1E0EE0FF10FC570C798&yid=DDA12465F03AF56A&vid=7801E6FC5AE9020C&iid=5D311CA918CA9A03&sid=8C5DE51F0A009A0F&eid=47F7649551A37CFC&journal_id=1000-3290&journal_name=物理学报&referenced_num=0&reference_num=0
