摘　　要：讨论了系统的态密度和玻色-爱因斯坦凝聚(BEC)空间维度性的关系,着重对幂外势和简谐外势作用下的低维BEC作了简单分析,得出无外势的低维BEC不可能产生,在外势作用下,一维和二维都能产生BEC.The discussion is made on the relation between the state density of systems and the dimensionality of Bose -Einstein Condensation（BEC）, with the further stress laid on the analysis of low dimensional BEC under the influence of power-law potential and harmonic potential. The result is the non-production of low dimensional BEC with no external potential and the production of one-dimensional and two-dimensional BEC under the power of external potential.

关 键 词：玻色-爱因斯坦凝聚(BEC) 外势 态密度
