高速运动电荷的辐射阻尼力

RADIATION DAMPING OF MOVING CHARGE AT HIGH SPEED

本文导出了高速运动电荷辐射阻尼力的相对论性表示式,得到了辐射阻尼力与能量平方成正比的关系,论证了高速时辐射阻尼力可以远大于外场力的结论,并对高速电荷在外场中的最终能量问题进行了讨论。

The paper derives an expression of relativity for radiation damping of a moving charge at high speed, gaining the result that the damping is proportional to squre of the energy. The radiation damping at high speed can be much greater than the applied field. Energy of a moving charge at high speed is discussed briefly when damping is much greater than the applied field.
