We present a study of planar physical solutions to the Lorentz-Dirac equation in a constant electromagnetic field. In this case, we reduced the Lorentz-Dirac equation to one second-order differential equation. We obtained the asymptotics of physical solutions to this equation at large proper times. It turns out that, in a crossed constant uniform electromagnetic field with vanishing invariants, a charged particle enters a universal regime at large times. We found that the ratios of momentum components that tend to constants are determined only by the external field. This effect is essentially due to a radiation reaction. There is no such effect for the Lorentz equation in this field.
我们给出了在恒定电磁场中洛伦兹 - 狄拉克方程的平面物理解的研究。在这种情况下,我们将洛伦兹 - 狄拉克方程简化为一个二阶微分方程。我们得到了该方程在大固有时间时物理解的渐近形式。结果表明,在不变量为零的交叉恒定均匀电磁场中,带电粒子在长时间进入一种普适状态。我们发现趋于常数的动量分量之比仅由外部场决定。这种效应本质上是由于辐射反作用。在该场中,洛伦兹方程不存在这种效应。
