摘要
从紫外光子与星际分子的相互作用出发,对与HⅡ区成协的星际脉泽提出了一种重要的激发机制.它能统一解释星际OH和水2种脉泽,并能满足各种天文条件,克服了以往某些模型的困难.
An important excitation mechanism for interstellar masers associated with H Ⅱ regions is presented, based upon the interaction beween ultraviolet photons and interstellar molecules. By using this mechanism, the unified interpretation of both interstellar OH and H<sub>2</sub>O masers can be argued, astronomical conditions can be satisfied, the difficulties of some models can be surmounted. So the bright future of this mechanism can be predicted.
