摘　　要：利用电磁场变换分析了带电粒子在磁场中的螺旋运动,基于康普顿散射理论和多普勒公式分析了虚光子与带电粒子的康普顿散射,并推导了在磁场中做螺旋运动的带电粒子的自发辐射波长公式.结果表明,当带电粒子在回旋脉塞的磁场中作螺旋运动时,在粒子静止系中可以观察到运动的周期性变化电场和磁场,即运动的虚光子.通过与带电粒子发生康普顿散射,虚光子能够转化为实光子辐射出去.The spiral motion of charged particles in magnetic field was analyzed by the transformations of the electromagnetic field.Besed on Compton scattering theory and Doppler formula,Compton scattering of virtual photon and charged particles was analyzed,and the wavelength formula of spontaneous radiation of the charged particles with spiral motion in magnetic field was derived.The results show that when charged particles performs spiral motion in magnetic field,the electric and magnetic field can be taken as periodic electric and magnetic field,and equivalent to virtual photon in the particle system.By Compton scattering of virtual photon and charged particles,the virtual photon can transformed into real photon to radiate out.
