在完成了斯特恩-盖拉赫实验之后，斯特恩在汉堡大学创立了分子束方法研究中心，制定了以分子束方法探究当时物理学前沿问题的UzM 计划.介绍了此一科学计划基本内容和实施过程，并讨论了其对近代物理学发展的影响.

After Otto Stern completed Stern-Gerlach experiment，he established a research center at the University of Hamburg for thoroughly studying the molecular beam method and carried out a plan called Untersuchung zur Molekularstrahlmethode ( UzM) to explore the frontiers in physics at that time using the molecular beam technique. In this paper，we have introduced the main idea of this scientific plan and its implementation process，and discussed the impacts of this plan on the development of the modern physics.
