Abstract
Let F={f(z)} be the family of the Meromorphic functions on the unit disc △, we discuss the relation for normalities between {f(z)} and {f(f(z))}, and the relation for normalities between functions and their k order derivative in this paper, we obtain some normal criteria of the family of meromorphic functions .
