摘要
介绍了天文成象中湍流大气的象质衰减参数：视宁度参数ｒ０，大气相干时间τ以及波前振幅的起伏（恒星闪烁σ２Ｉ），讨论了它们对成象的影响，其中着重讨论了ｒ０的物理本质并对其进行了定量分析。
Parameters of the image degradation include the seeing parameter r 0, coherent time τ and the amplitude fluctuation (Stellar scintillation: σ I 2) of the turbulent atmosphere are introduced in this paper. The influence of these parameters on the image degradation is discussed. The physical meaning of the seeing parameter r 0 is especially discussed and is quantitatively analysized.
