我们从激发、离解和电离的微观细节以及这些过程的组合来研究电子对水蒸气的影响。基本的电子碰撞截面数据以多种形式组合在一起，并被合并成适合于用数字计算机分析的半解析函数。讨论了水蒸气中的能量沉积，给出了能量损失函数，以及每离子对的电子伏特和各种过程中的能量损失效率。我们考虑了电子和水蒸气相互作用在大气科学中的几个应用，特别是水彗星、极光和气辉以及闪电。一般来说，我们发现，除了闪电的情况外，其他过程更可能是H*、O*和OH*排放的来源。
We examine the consequences of electron impact on water vapor in terms of the microscopic details of excitation, dissociation, and ionization and combinations of these processes. Basic electron-impact cross section data are assembled in many forms and are incorporated into semi-analytic functions suitable for analysis with digital computers. Energy deposition in water vapor is discussed and the energy loss function is presented, along with the ‘electron volts per ion pair’ and the efficiencies of energy loss in various processes. We consider several applications of electron and water-vapor interactions in the atmospheric sciences, in particular, H2O comets, aurora and airglow, and lightning. In general we find that, except in the case of lightning, other processes are more likely sources of H*, O*, and OH* emissions.
