摘要 本文主要研究了全纯函数的差分算子分担一个值的唯一性问题,并且得到了:若f与g为超级ρ2<1的两个非常数的超越全纯函数,n,k,m为满足n≥5k+4m+13的整数,c是满足f(z+c)-f(z)≠0且g(z+c)-g(z)■0的非零常数,则若f(z)~n(f(z)~m[-1)(f(z+c)-f(z))]^(k)与g(z)~n(g(z)~m[-1)(g(z+c)-g(z))]^(k)IM分担1,则f=tg,其中t为满足t^(n+1)=1与t^m=1的常数. In this paper, we deal with the value distribution of difference operators of entire functions and obtain that. Let f and g be transcendental entire functions of p2 〈 1 , n,k,m are three integers satisfying n ≥ 5k + 4m + 13 , c is a nonzero complex constant such that f(z + c) - f(z) ≠ 0 and g(z + c) - g(z)≡/0, and if [f(z)n(f(z)m - 1)(f(z +c) -f(z))](k) and [g(z)n(g(z)m - 1)(g(z +c) -g(z))](k) share 1 IM, thenf=tg foraconstanttwith tn+1 = land tm= 1.
