摘　　要：斯特恩-盖拉赫实验在近代物理实验中的地位举足轻重.就实验方法而言,其核心部分分子束方法影响了后世许多重要的物理实验.就量子力学的基本原理而言,它既是量子态制备的范例,又是一些量子测量的成功典例.通过对大量相关文献的调研和挖掘,立足于物理原理与史料相结合的研究方法,期望尽量真实地还原斯特恩-盖拉赫实验的历史事实,着重理清该实验与电子自旋、角动量空间取向量子化这两个概念之间的关系.Stern- Gerlach experiment plays a decisive role in the modern physics experiment. As far as the experimental method is concerned,the molecular beam method created by this experiment has influenced many important physical experiments. As far as the basic principle of quantum mechanics is concerned,it is an example of quantum state preparation and a successful example of some quantum measurement. Based on a large number of related literature research and the combination of physical principles and historical materials,we hope to restore the true historical facts of Stern- Gerlach experiment. The focus is on clarifying the relationship between the experiment and the orbital angular momentum space quantization and electron spin.
