英文摘要:
      The purpose of this paper is to study almost cosymplectic $p$-spheres and almost cosymplectic metric bi-structures. Firstly, we show some properties of almost cosymplectic $p$-spheres. Then we introduce the notion of almost cosymplectic metric bi-structures and give some results on three-dimensional manifolds admitting almost cosymplectic metric bi-structures. Moreover, we investigate three-dimensional manifolds with almost cosymplectic metric bi-structures when the $(1, 1)$-type tensor fields $h_1$ and $h_2$ are being of codazzi type and cyclic parallel.
