This paper study the informality of the family of meromorphic functions , has been a general positive criterion . Suppose F is defined in the complex plane region D family of meromorphic functions , k is a positive integer , for any f ∈ F, f zero weight class is at least k (k ≥ 2), b (≠ 0), c (≠ 0) for the finite complex M ( ( ? ) 4 | B | ) is a positive number , a_i ( z ) , b_i ( Z ) analytic functions on D (i: 1,2, ... k) and satisfies then F is normal in D .
