摘要
根据几何光学中的 Ｆｅｒｍａｔ原理及统计概念，推导了光线在湍流大气中传播的分 布函数，并计算了恒星光线通过对流层发生闪烁的单色亮度起伏和星象的抖动振幅。
Starting from the Fermat's principle in gemetrial optics and statistical concepts, the author has derived the distribution function of light ray's propagation in atmospheric turbulence, and then calculated the fluctuation of monochrome brightness of the scintillation taking place when the lights of star come across the troposphere, and the amplitude of the tremble of stellar images.
