| 摘 要： | 针对星际ＯＨ自由基及ＯＨ脉泽起源的多种解释各自存在的困境，抓住ＯＨ的生成环境特征，从星形成区紫外光子与Ｈ２Ｏ分子的相互作用出发，对ＯＨ自由基的产生与ＯＨ脉泽的激发机制提出一种新解释。这种新解释克服了过去提出的辐射机制的困难，并且能满足各实际天文条件，因此是一种有前途的机制。

| Abstract: | There are rich OH radicals and their masers have been observed in interstellar space. Their origin and evolution have not been understood well yet. By addressing the formation of OH radicals and their population inversion, we propose a new scenario for the origin of OH masers. This mechanism has overcome the defects of former radiation mechanism. And it is both simple and associated with astronomical conditions. The bright future can be predicted. |
