摘要
应用数值计算的方法计算了谐振势阱中有弱相互作用的玻色气体凝聚的临界温度和基态占据率。计算结果表明，二者都随着散射长度的增大而减小；但与理想玻色气体相比仅差约０４％。
The critical temperature and the ground state fraction of weakly interacting Bose Einstein condensation in a harmonic potential trap are calculated with numerical method. The result indicates that both are decreasing with the scattering length increasing. But, there is only a difference about 0.4% between it and that of ideal case.
