摘　　要：文章首先回顾了分子在外场中的三个效应及其冷分子被外场操控的基本原理,接着简单介绍利用分子与电磁场的相互作用来实现分子束减速的基本原理。随后详细介绍各种分子束减速的技术方案、实验结果及其最新研究进展,包括分子束的静电Stark减速、静磁Zeeman减速和光学Stark减速技术。最后,简单介绍了由上述减速技术获得的冷分子样品在冷碰撞物理、冷化学物理和精密测量物理等领域中的应用研究。We first introduce three effects arising from the interaction of electromagnetic fields with molecules, as well as the basic principle of manipulating cold molecules using external fields, including the deceleration of molecular beams using electromagnetic fields. Various deceleration methods for molecular beams involving electrostatic Stark deceleration, magneto- static Zeeman deceleration and optical Stark deceleration will be given, together with the experi- mental results and recent research progress. Finally, we will briefly present the applications of cold molecules prepared by the above methods in the fields of cold collision, cold chemistry, and precision measurements.
