各种等离子体的性质是由原子辐射和等离子体粒子之间发生的碰撞过程决定的，因此，这些过程的有效截面和速率系数的详细知识是非常必要的。在这项工作中，电荷变化过程，主要是重粒子碰撞，包括杂质离子，考虑使用可用的计算机代码，并讨论了背景物理。除一般特征外，还考虑了在大多数等离子体中经常观察到的等离子体原子和离子亚稳态的作用，这些亚稳态在等离子体形成中起着关键作用。在重粒子碰撞中观察到的非线性效应，如密度效应和多电子电离，也被考虑在内。此外，还简要讨论了α粒子与氢及其同位素（D和T）碰撞中与电子捕获有关的同位素效应
Properties of various kinds of plasmas are determined by atomic radiation and collision processes occurring between plasma particles, therefore, the detailed knowledge of the effective cross sections and rate coefficients for these processes is highly required. In this work, charge-changing processes, mainly for heavy-particle collisions, including impurity ions, are considered using available computer codes, and the background physics is discussed. Besides general features, the role of metastable states of plasma atoms and ions, which are often observed in most of plasmas and play a key role in plasma formation, is considered. The non-linear effects observed for heavy particle collisions, such as the density effect and multiple-electron ionization, are also considered. In addition, the isotope effects are briefly discussed related with electron capture in collisions of alpha particles with hydrogen and its isotopes (D and T). c
