In this paper, we study the value distribution of meromorphic functions concerning differential polynomial. Moreover, some criteria for normality of families of meromorphic functions are obtained, which extend results respectively established by Chen and Fang, Pang and Zalcman. 2000 Mathematics Subject Classification: 30D35, 30D45.
