The Abraham–Lorentz–Dirac theory predicts vanishing radiation reaction for uniformly accelerated charges. However, since an accelerating observer should detect thermal radiation, the charge should be seen absorbing photons in the accelerated frame which, if nothing else occurs, would influence its motion. This means that either there is radiation reaction seen in an inertial frame or there should be an additional phenomenon seen in the accelerated frame countering the effect of absorption. In this paper I rederive the Abraham–Lorentz–Dirac force from quantum electrodynamics, then I study the case of a uniformly accelerated charge. I show that in the accelerated frame, in addition to the absorption of photons due to the Unruh effect there should also be stimulated emission. The net effect of these phenomena on the motion of the charge is found to be zero.

亚伯拉罕-洛伦兹-狄拉克理论预测均匀加速电荷的辐射反应消失。但是，由于加速的观察者应该检测到热辐射，因此应该看到电荷吸收了加速框架中的光子，如果不发生其他情况，则将影响其运动。这意味着，要么在惯性框架中看到辐射反应，要么在加速框架中看到额外的现象，以抵消吸收的影响。在本文中，我从量子电动力学中重新得出了亚伯拉罕-洛伦兹-狄拉克力，然后研究了均匀加速电荷的情况。我表明，在加速帧中，除了因Unruh效应而吸收光子外，还应激发发射。
