摘要: 讨论基于辐射等效温度和基于电子温度的两种群参数平均方法,给出结论:基于电子温度的Rosseland方法优于基于辐射等效温度的平均方法,并有数值例子验证.

关键词: X光辐射传输, 群参数方法, Rosseland平均

Abstract: Comparing two multigroup methods that the means of Rosseland mean at local material temperature (method 1) and the means based on the local effective radiation temperature (method 2),a conclusion that method 1 is superior to the method 2 in ICF radiation transfer calculation is drawn. Some numerical results are presented.

Key words: radiation transfer, multi-group parameters, Rosseland average
