摘　　要：用严格的方法重新详细的讨论了半自旋粒子在旋转磁场中波函数的演化并求解了非绝热几何相。和文献[4]比较,得到了文献[4]所有的重要结果,但更加简洁,清晰和有启发性。Using a rigorous method of solution, we generally restudy the evolution of spin states in rotational magnetic fields and obtain its geometric phase. Compared with Ref. [4 ], We have obtained all important resuits of Ref. [ 4 ], however our treatment and conclusion both are rigorous, succinct and instructive.
