摘　　要：研究了１十１维ＣＰ１模型的拓扑项的可移性，求得了移去ＣＰ１模型拓扑项的么正变换，并且找到了拓扑项与　真空以及几何相因子的关系．In this paper, the removability of the topological term in the 1 + 1 dimension CP1 model is studied. The unitary transformation which removes the topological term in the CP1 model is obtained. The relation of the topological term to the a vacuum and geometric phase is found.

关 键 词：CP^1模型 拓扑项 可移性
