摘要：We study the normality of families of meromorphic functions related to a result of Drasin. We consider whether a family meromorphic functions ℱ whose each function does not take zero is normal in 𝐷, if for every pair of functions 𝑓 and 𝑔 in ℱ, 𝑓(𝑧) and 𝑔(𝑧) share ∞ or 𝐻(𝑓)−1 and 𝐻(𝑔)−1 share 0, where 𝐻(𝑓)∶=𝑓(𝑘)(𝑧)
