摘　　要：运用矩阵法研究了Bose-Einstein凝聚体的低激发态能谱,并讨论了微扰对低激发态的影响.通过研究发现,对于相同的能级,在原子数较小的情况下,凝聚体产生的自恰场的近似符合的很好。We study the energy spectrum of low excited state of Bose-Einstein condensate by matrix method in this paper and discuss the peturbation's influence on low excited state. The result indicates that self-consistent field approximation produced by condensate accords with experiment very well at the same energy level when the atom munber is small.
