宇宙中大部分重子物质都以H2的形式存在，其中包括银河系和河外星际云中的大部分气体。分子氢在建立许多天体物理环境中的热平衡方面起着重要作用，并且可以作为气体的光谱诊断。对这种环境的观测进行建模和解释需要对H2进行定量完整和准确的处理。利用这个H2的微物理模型，我们给出了典型天体物理环境的说明性计算。这项工作为未来研究这些和其他H2是重要组成部分的环境奠定了基础。
Much of the baryonic matter in the universe is in the form of H2, which includes most of the gas in Galactic and extragalactic interstellar clouds. Molecular hydrogen plays a significant role in establishing the thermal balance in many astrophysical environments and can be important as a spectral diagnostic of the gas. Modeling and interpretation of observations of such environments requires a quantitatively complete and accurate treatment of H2. Using this microphysical model of H2, we present illustrative calculations of prototypical astrophysical environments. This work forms the foundation for future investigations of these and other environments in which H2 is an important constituent.
