Induction-by-stages of Dixmier algebras and orbit datum and its application

The purpose of the present note is to prove that the parabolic inductions of the orbit datum and Dixmier algebras can be induced by stages. And as an appliction, we have proved that for SO(2n+1, C), SP(2n, C), F-4 and G-2, the inductions of complete prime Abel orbit datum are independent of the Choice of parabolic subgroups.
