摘　　要：通过讨论弱简并理想玻色(费米)气体的性质,可以看出由微观粒子全同性带来的量子统计关联对系统宏观性质的影响,在弱简并的情形下nλ3较小,这个影响是微弱的.引进了有效数密度的概念,对玻色-爱因斯坦凝聚(BEC)在球谐势阱中理想玻色气体的临界温度进行探讨.Through discussion of weak degeneration ideal Bose(fermium),we can see the effect of the quantum statistic connection brought about by the micro particle entire homogeneity on the macroscopic nature of the system.nλ3 is small and this influence is weak in the weak degeneration situation.The paper introduces the concept of significant density and explores the critical temperature of Bose-Einstein condense(BEC) in the ball harmony potential well in the ideal Bose gas.

关 键 词：玻色-爱因斯坦凝聚 临界温度 有效数密度
