摘　　要：在经典电动力学的基础上,讨论了辐射阻尼影响下非相对论性带电粒子在均匀磁场中的经典运动.导出了辐射带电粒子的运动方程(阿伯拉罕—洛仑兹方程),利用微扰法求解该运动方程的初值,得到了带电粒子的轨道方程,得出带电粒子辐射功率随时间的变化规律,并讨论了所得结果的适用性.On the basis of classical electrodynamics, the classical motion of non-relativistic charged particle affected by radiantly damping force in equally magnetic field was discussed in the peper. The motional equation of radiantly charged particle was deduled, an initial value of the equation was found by the method of microscopic variations, and an orbital equation of charged particle was obtained. A varying law of radiant power with time was presented, and the suitability of result was discussed.
