我们对遥远等离子体物理过程的大部分知识是通过测量它们产生的辐射获得的。在这里，我们概述了主要的碰撞和辐射过程以及与等离子体中微物理过程相关的诊断示例。许多分析假设等离子体具有时间稳定，离子居群与局部温度和粒子速度的麦克斯韦分布处于平衡状态，但这些假设在许多情况下很容易被违背。我们将详细考虑这些偏离平衡和可能的诊断。
Most of our knowledge of the physical processes in distant plasmas is obtained through measurement of the radiation they produce. Here we provide an overview of the main collisional and radiative processes and examples of diagnostics relevant to the microphysical processes in the plasma. Many analyses assume a time-steady plasma with ion populations in equilibrium with the local temperature and Maxwellian distributions of particle velocities, but these assumptions are easily violated in many cases. We consider these departures from equilibrium and possible diagnostics in detail.
