首先，给出了包含大气湍流内，外尺度效应的折射率功率谱密度函数。

Firstly, the power spectral density function of refractive index is given including the effects of inner and outer scale of the turbulence.

随着等效湍流外尺度的增加，低频谱的幅值逐渐增大，高频谱保持不变。

With the outer scale of turbulence increasing, the amplitude of low-frequency spectrum increases and the high-frequency is invariable.
