摘要：
我们证明了自旋1玻色-爱因斯坦凝聚态基态的一些特征，这些特征来源于数值模拟。对于铁磁系统，我们证明了单模近似（SMA）的有效性。对于具有非零磁化抗铁磁系统，我们证明了m_F=0组分的消失。在论文末尾，一些剩余的退化情况也被讨论。主要结果的证明均基于一个简单的观察：不同组分之间质量的重新分配会减少动能。
英文摘要：
We justify some characterizations of the ground states of spin-1 Bose-Einstein condensates exhibited from numerical simulations. For ferromagnetic systems, we show the validity of the single-mode approximation (SMA). For an antiferromagnetic system with nonzero magnetization, we prove the vanishing of the $m_F=0$ component. In the end of the paper some remaining degenerate situations are also discussed. The proofs of the main results are all based on a simple observation, that a redistribution of masses among different components will reduce the kinetic energy.
