The authors discuss the normality concerning holomorphic functions and get the following result. Let F be a family of holomorphic functions on a domain D aS, a",, all of whose zeros have multiplicity at least k, where k a parts per thousand yen 2 is an integer. And let h(z) a parts per thousand cent 0 be a holomorphic function on D. Assume also that the following two conditions hold for every f a F: (a) f(z) = 0 a double dagger' |f ((k))(z)| < |h(z)|; (b) f ((k))(z) not equal h(z). Then F is normal on D.
