摘要
对复平面上的超越亚纯函数ｆ（ｚ），研究了ｆ·（ｆ（ｋ））ｎ的值分布情况（其中ｎ和ｋ都是不小于１的正整数），并且考虑了ｎ＝１时ｆ·（ｆ（ｋ））ｎ的值分布情况，给出了一个定量估计．
Let f(Z) be a transcendental meromorphic function in the complex plane. The valuedistribution of f(f(k) )n is studied and some results are obtained. They are improvementsof that C. K. Tse and C. C. Yang. The case for n=1 and get a quantitative estimation offf(k) is also studied.
