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难,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了一种新解释.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.
針對星際OH自由基及OH脈澤起源的多種解釋各自存在的睏難,抓住OH的生成環境特徵,從星形成區紫外光子與 H2O分子的相互作用齣髮,對OH自由基的產生與OH脈澤的激髮機製提齣瞭一種新解釋.這種新解釋剋服瞭過去提齣的輻射機製的睏難,併且能滿足各實際天文條件,因此是一種有前途的機製.

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.
