星际γ射线谱线辐射流量的估算和来源探讨(Ⅱ)——新星、SNIa的贡献和新星模型的限制性条件

THE FLUX ESTIMATE AND SOURCE DISCUSSION ABOUT INTERSTELLAR GAMMA-RAY LINE EMISSION (Ⅱ)——THE CONTRIBUTION FROM NOVA, IA SUPERNOVA AND THE CONSTRAINT CONDITION OF THE NOVA MODEL

运用四种星体空间分布模型和新星（及ＳＮＩａ）的最新核物理数据，计算了它们所产生的（５条）γ射线谱线辐射流量及核素丰度。结果表明，如果只根据“物理因子”上限，新星可能成为＾２６Ａｌ的主要来源之一，然而由于核素丰度值的要求，新星模型本身仍存在难以克服的困难，另还指出，谱线轮廓的研究也将为本文探讨的问题提供重要判据。

Using four kinds of stellar space distribution models in the Galaxy and recent nuclear physical data, the flux values of five Gamma-ray lines and nuclide abundances yielded from novae (and Ia supernova also) are caculated. The results show that nova is probably one kind of main sources only under the uplimit of the "physical Factor", but because of the constraint of nuclide abundances, there is a big difficulty in the nova model still. It is pointed out too that the research on the profile of Gamma-ray line at 1.809 Mev will provide important criterion for problems approached in this paper.
