摘要：

In this paper, we investigate excited characteristic of the weakly interacting quasi-one-dimensional(1D) and quasi-two-dimensional(2D) Bose–Einstein condensation(BEC) in harmonic potential trap. The energy spectrum and the analytical expression of the sound velocity are obtained and analyzed. Compared with 3-Dimensional homogeneous Bose-condensed gas occasion, the sound velocity of 2D Bose-Einstein condensation in harmonic potential trap is smaller.
