An Effective Method for Treating the Blanketing Effect of A Non-LTE Line

In this paper, a new method, i. e. the approximate lambda operator methcd introduced by Werner(1986) is proposed in detail for calculating the Non-LTE stellar atmospheric model and for treating the blanketing effect of the Non-LTE line effectively, on the basis of the analysis of the fact that the completely linearized method can not be used to deal with the blanketing effect of the Non-LTE line well. And the advantages, disadvantages and possible application of the method are also analysed and discussed.
