利用局域密度近似(LDA)导出了简谐势阱中存在弱相互作用的旋转玻色气体发生玻色-爱因斯坦凝聚时的粒子数、相变温度和基态粒子占据率的解析表达式，探讨了粒子间相互作用对相变温度和基态粒子占据率的影响. 计算表明，当粒子间的相互作用消失时，所有解析结果均能够与相互作用的旋转理想玻色气体获得很好的一致．
The analytical expressions of particle number, transition temperature and ground state fraction for rotating weakly interacting Bose gases confined in a harmonic trap are derived by using the local density approximation (LDA). The effects of weakly interaction on transition temperature and ground state fraction are discussed. When the interaction disappears, these results completely coincide with those calculated for the case of rotating ideal Bose gases.
