对于辐射带电粒子来说，辐射反作用力在决定其运动方面起着重要作用。已经提出了几个公式来描述辐射反作用力。获得了 Lorentz-Abraham-Dirac (LAD)、Mo-Papas、Landau-Lifshitz 和 Ford-O'Connell 方程的稳态解，并针对静磁场和旋转电场下的带电粒子进行了比较。获得的解决方案的行为看起来非常相似。评估洛伦兹因子的相对差异，使用 LAD 方程与其他方程相比计算值；这些值被证明小于经典辐射反应适用的范围。
For a radiating charged particle, the radiation reaction force plays an important role in determining its motion. Several formulas have been proposed to describe the radiation reaction force. Stationary solutions of the Lorentz-Abraham-Dirac (LAD), Mo-Papas, Landau-Lifshitz, and Ford-O'Connell equations are obtained and compared for a charged particle under a static magnetic and a rotating electric field. The behaviors of the obtained solutions look quite similar. The relative differences of the Lorentz factor, calculating the values using the LAD equation compared to the other equations, are evaluated; these values are shown to be less thanin the regime where classical radiation reactions are applicable.
