摘要
指出湍流大气中光传播理论分析与数值模拟方法存在的问题，简要分析了湍流谱的适用性与局限性，考察了湍流特征尺度在光传播问题中的作用，构造了与实验结果相符的湍流温度场的间歇性模型。
The turbulence spectrum and intermittency problem concerning light propagation in the atmosphere are addressed. The validity and limitation of current turbulence spectrum models are discussed, and roles of turbulence characteristic scales are analyzed. A experimentally tested model for temperature structure functions in fully developed turbulence is developed. The model can be used for the construction of the random phase screen in the numerical simulation of light propagation in order to study the effect of turbulence intermittency on light propagation.
