讨论了一般微分单项式的值分布,得到定理:设f 是平面上的超越亚纯函数. F=fn0(f(i))ni…(f(k))nk -c,ni≥1,c≠0是常数,那么 (n0-2)T(r,f)≤(r,(1[ 〗F)+S(r,f) n0>2rnT(r,f)≤[ SX(〗7(i+1))/(i)(i)(r,(1[ 〗f))+(r, (1)/(F[ SX)〗))+S(r,f) n0=1rnT(r,f)≤7(N(r,(1)/(f[ SX)〗)+(r, (1)/(F[ SX)〗))+S(r,f) n0=0.%Value distrib utions of the general differential monomials is discussed.The following theorem is obtained:Let f be a transcendental meromorphic funct ion in the plane,F=fn0(f(i))ni… (f(k))nk-c,ni≥1,c≠0 be a constan t then (n0-2)T(r,f)≤(r,(1F)+S(r,f) when n0>2;T(r,f)≤7(i+1))/(i)(i)(r,(1f))+(r,(1)/(F))+S(r,f) when n0=1;T(r,f) ≤7(N(r, (1)/(f)+(r, (1)/(F))+S(r,f) when n0=0.
