摘　　要：研究了在绝对零度下2个平行板之间周期边界条件下均匀稀释玻色爱因斯坦凝聚体中的类Casimir力,得到Bogoliubov色散关系的高阶修正项.计算中没有引入任何截断函数,获得了有限的结果.该结果有助于进一步了解玻色爱因斯坦凝聚体的物理机制,并且对Casimir效应和玻色-爱因斯坦凝聚的实验研究具有一定的参考价值.The Casimir-like effect is investigated in dilute Bose-Einstein Condensation at zero- temperature between the two parallel plates with periodic boundary conditions. Obtained the much smaller Bogoliubov corrections due to the nonlinearity of the Bogoliubov dispersion relation. In the calculation, any ultraviolet cut-off parameter was not introduced. These results will will help us further understand the physical effect in the Bose-Einstein condensed body and provide certain reference value to Casimir effect and the Bose-Einstein Condensation experimental study.
