摘　　要：基于解析和数值方法计算了两维简谐势阱中旋转玻色子的粒子流密度函数,重点讨论了凝聚玻色子的影响.结果表明:凝聚在基态的玻色子在粒子流密度的空间分布中起着决定性作用.The particle flow distribution for rotating bosons confined in a two dimensional harmonic trap is derived by the analytical and numerical methods.The influence of condensed bosons is mainly discussed.It indicates that the bosons condensed in the ground state play an important role in the spatial distribution of the particle flow.

关 键 词：凝聚玻色子 粒子流密度 简谐势阱
