摘要从描述玻色爱因斯坦凝聚的基本方程(Gross-Pitaevskii方程)出发,利用一种半经典的方法对其基态的稳定性进行了分析,发现在一维有限体系内其基态定态解是稳定的.这个结果与利用其他方法所得到的结果相一致. In this article, starting from Gross-Pitaevskii Equation, which is a basic equation to describe the properties of the Bose-Einstein condensates （BEC）, we investigate the stability properties of the ground state for BEC with 1-dimensional square well by one kind semi-classical method. Our results show that the ground state is stably and is consistent with the exiting literatures.
