摘　　要：通过给出三体量子纯态可分的一个充分必要条件,得到了量子系统C^2C^2,C^2C^2C^2和C^2C^2C^n中可分纯态的具体形式及其分量之间的关系,进而揭示了可分纯态的结构,并给出三体可分纯态两种表示之间的关系.We gave a sufficient and necessary condition for a separable tripartite quantum pure state,obtained the relationship between the specfic form and components of a separable pure state of the quantum system C^2×C^2,C^2×C^2×C^2 and C^2×C^2×C^n,respectively,and then revealed the structure of the separable pure states.We gave a relationship between two representations of a separable tripartite quantum pure state.
