研究整函数及其微分多项式的CM分担值,用权分担的思想,得到以下结果:若f,g为两个非常数整函数,n,k为两个正整数,如果(f n)(k)与(gn)(k)分担(1,l),且满足下列条件之一:(i)当l =1时,n >4k +92;(ii)当l =2时,n >3k +4;那么f =c1ecz,g =c2e-cz或者f =tg;其中c,c1,c2,t为满足(-1)k(c1c2)n(nc)2k =1及tn =1的常数。

This paper deals with entire functions concerning their differential polynomials , weaken the re-striction of CM sharing of the values 1, and obtains the results as follows:Let f and g be two non-constant entire functions, and let n and k be two positive integers.If (f n)(k) and (gn)(k)share (1,l) , and if one of conditions (i) l =1 and n >4k +92 ;(ii) l =2 and n >3k+4;satisfied, then either f =c1ecz,g =c2e-cz where c, c1 , and c2 are three constants satisfying (-1)k(c1c2)n(nc)2k =1 or f(z) =tg(z) for a constant t such that tn =1.
