摘要：

Let k (>= 2) be a positive integer, let F be a family of meromorphic functions in a domain D, all of whose zeros have multiplicity at least k + 1, and let a(z) (not equal 0), h(z) (not equivalent to 0) be two holomorphic functions on D. If, for each f is an element of F, f = a(z) double left right arrow f((k)) = h(z), then F is normal in D. (C) 2009 Published by Elsevier Inc.
