| 摘 要： | 通过引入压缩变换，在忽略微扰项的情况下，有限长运动边界圆柱型势阱等价于一个荷电粒子与电磁矢势相互作用的量子体系．求出了由于压缩变换而导致的Ｂｅｒｒｙ相因子．并利用量子么正变换引起拓扑项的可移性，求出了微扰项在一级近似下对Ｂｅｒｒｙ相因子的贡献．

| Abstract: | By introducing the squeezing transformations and omitting perturbation term,the finite deep column potential well with motive boundary is equivalent to a quantum system which the particles interact with the electromagnetic vector potential.Berry phase originating from the squeezing transformations is derived. By using the removability of the topological term induced by the quantum unitary transformation,Berry phase of the perturbation term under one-order approximation is obtained. |
