摘　　要：Arhangel' skit posed the problem:How a class of topological spaces has the orthogonality or cleavability? The partial solution on this problem has been obtained for the class of spaces which are multiplicative by Arhangel' skit, Bella and the others. In this paper we shall prove that some classes of generalized metric spaces which are non-multiplicative also have the orthogonality or cleavability.
