文摘This paper studied the connection between normal family and unicity, and proved some results on unicity of entire functions. Mostly, it was proved: Let f be a nonconstant entire function, and let a, c be two nonzero complex numbers. If E(a,f)=E(a,f' ), and f"(z)=c whenever f' (z)=a, then f(z)=Ae^(cz)/u +(ac-a^2)/c.The proof uses the theory of normal families in an essential way.
