Abstract: Introducing the concept of projective operators and self-adjont operators of inner  product H-Z-spaces,this paper dicusses the nature of projective operators on inner product  H-Z-spaces,and analyzes the nature of projective operators on Hilbert spaces being established in inner  product  H-Z-spaces.
