A real or virtual photon may spontaneously annihilate.

一个实的或虚的光子可以自发地湮没。

By Compton scattering of virtual photon with relativistic electron, the virtual photon can be transformed into real photon to radiate out.

当虚光子与作沟道运动的电子发生康普顿散射时，虚光子就会转化为实光子辐射出去。

Considering recoil of electron, a new theory to explain axial channelling radiation is presented based on Compton scattering of virtual photon with relativistic electron.

考虑电子的反冲的影响，利用虚光子与相对论电子的康普顿散射理论对轴沟道辐射进行了研究。
