本文讨论了电磁光波散射时的远区光谱各向同性。研究表明，电磁光波散射时远区光谱各向同性的充分条件可以用两个条件来表示：散射介质的介电常数的两点相关函数服从标度律，入射光波的归一化光谱沿两个垂直方向沿着具有相同的分布.
The far-zone spectral isotropy of an electromagnetic light wave on scattering has been discussed. It is shown that a sufficient condition for the far-zone spectral isotropy of an electromagnetic light wave on scattering can be expressed by the following two requirements: the two-point correlation function of the dielectric susceptibility of the scattering medium obeys the so-called scaling law, and the normalized spectrum of the incident light wave has the same distribution along the two perpendicular directions.
