摘　　要：本文证明了Ｓａｓａｋｉ空间形式中具有η－平形第二基本形式的η－Ｅｉｎｓｔｅｉｎ－Ｓａｓａｋｉ子流形在某些假定下由它的谱所决定；In this paper, we verify that an η Einstein Sasakian submanifold with the η parallel second fundamental form in a Sasakian space form is determined by its spectrum under some assumptions; and give the spectral characterization of the circle bundle over the complex quadric.
