摘要: A method for treating the effects of partial frequency redistribution in non-LTE transfer problems is presented. This formulation appropriate to spectral lines arising from sharp lower levels. Numerical examples solar L$alpha$ and Ca ii K line profiles are presented compared with obtained by Milkey his collaborators. (AIP)
