We discuss several types of regions in the interstellar medium of the Milky Way and other galaxies in which the chemistry appears to be influenced or dominated by surface and solid-state processes occurring on or in interstellar dust grains. For some of these processes, for example, the formation of H₂ molecules, detailed experimental and theoretical approaches have provided excellent fundamental data for incorporation into astrochemical models. In other cases, there is an astrochemical requirement for much more laboratory and computational study, and we highlight these needs in our description. Nevertheless, in spite of the limitations of the data, it is possible to infer from astrochemical modelling that surface and solid-state processes play a crucial role in astronomical chemistry from early epochs of the Universe up to the present day.
我们讨论了银河系和其他星系中的几种星际介质区域，在这些区域中，化学似乎受到或主要由发生在星际尘埃颗粒上或内部的表面和固态过程的影响。对于其中一些过程，例如 H₂分子的形成，详细的实验和理论方法已经为纳入天体化学模型提供了极好的基础数据。在其他情况下，需要进行更多的实验室和计算研究，我们在描述中突出了这些需求。然而，尽管数据存在局限性，但仍可以从天体化学模型推断出，表面和固态过程在从宇宙早期到现在的天文学化学中起着至关重要的作用。
