中文摘要：

获得超冷分子是超冷原子分子物理领域的新的热点研究课题。分子具有更多的自由度，能级结构密集、复杂，直接激光冷却存在困难。目前，人们一般借助外场把超冷原子耦合获得超冷分子。受激拉曼绝热通道技术（stimulated Raman adiabatic passage，STIRAP）作为其中一种非常有效地将超冷原子转化为超冷分子的方法已被广泛地研究。该文主要针对STIRAP过程中超冷原子一分子转化系统的动力学，绝热性、稳定性等理论研究的进展进行综述。

英文摘要：

The generation of ultracold molecules has been a hot topic in cold atom-molecule physics. It is difficult to obtain ultracold molecules with laser cooling as in the atomic system, because there are more degrees of freedom in molecules, and the level structure is denser and more complicated. For the time being, the ultracold molecules are generally generated from the ultracold atoms coupled by the external fields. The stimulated Raman adiabatic passage process （STIRAP） as an effective method of generating ultracold molecules from its atomic counterparts has been widely studied. In this article, we mainly focus on the recent research progress of dynamics, adiabaticity and instability of the dark state in the atom-molecule STIRAP.
