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。

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

微分散射截面的变化主要依赖于相对介电常数实部、虚部数值较大的一方，并且随粒子取向角的增大而增大。

The variation of DSCS depends on the larger part between real part and imaginary part of dielectric coefficient. The DSCS and azimuth angle are in proportional relation.
