| 摘 要： | Let E be a compact Lie group, G a closed subgroup of E, and H a closed normal sub-group of G. For principal fibre bundle (E,p, E,/G;G) tmd (E/H,p‘,E/G;G/H), the relation between auta(E) (resp. autce (E)) and autG/H(E/H) (resp. autGe/H(E/H)) is investigated by using bundle map theory and transformation group theory. It will enable us to compute the group JG(E) (resp. SG(E)) while the group J G/u(E/H) is known.

| Abstract: | Let E be a compact Lie group, G a closed subgroup of E, and H a closed normal subgroup of G. For principal fibre bundle (E,p, E/G;G) and (E/H,p′, E/G;G/H), the relation between autg(E) (resp. aut

(E)) and aut
G

(E/H) (resp. aut
