envelope factor
解釋
包亦因數-
( 2000 ). the neutron irradiation is assumed to derive primarily by the reaction 13c ( a, n ) i60 with a minor contribution from the marginal burning of 22ne through the channel 22ne ( a n ) 23mg in the final, high temprature phase of each flash. and we considered the influence of the various parameters such as the initial core mass, the envelope mass, the mass - loss rate, the overlap factor and the delution factor etc., and we vary their value with the pulse number
本文採用分叉s -過程反應通道,以~ ( 13 ) c ( , n ) ~ ( 16 ) o 、 ~ ( 22 ) ne ( , n ) ~ ( 25 ) mg為雙脈沖中子源,用最新的中子俘獲截面,利用gallino和busso等人給出的agb星三殼層核合成模型,考慮到核心質量、挖掘程度、重疊因子、稀釋因子及星風質量損失率隨脈沖數的變化,詳細計算和研究了各個金屬豐度情況下的3m 。 -
In fact, the envelope is identical in each case except for a scale factor.
事實上,在這幾種情況下,除差一個倍率外,包絡是是完全相同的。
