Average densities of T 1 and T 8. a There is a γ A -interval where average densities of T 1 and T 8 are decreasing as γ A increases for fixed γ B =3×10−9 g/cm3·day. b The γ A -interval where average T 1 and T 8 are decreasing may shrink as γ B is taken to be smaller, e.g. γ B =0.1×10−9 g/cm3·day. Here, γ A varies between n.4×10−9 g/cm3·day and all other parameter values are the same as in Tables 2 and 3
