摘要: 设~$\{f_{n}\}$~是区域~$D$~内的亚纯函数列,~其零点的重级均~$\geq3$,
且均仅有一个重级极点.
~$\{h_{n}\}$~是~$D$~内的亚纯函数列,~且~$h_{n}\Rightarrow h$~于~$D$,
$h \not \equiv \infty,h \ne 0$. 若~$f'_{n}\ne h_{n}$,
则~$\{f_{n}\}$~在~$D$~内正规.

关键词: 亚纯函数, 正规族, 例外函数列

Abstract: Let~$\{f_{n}\}$~be a sequence  of meromorphic functions on
a domain~$D$,~all of whose zeros have multiplicity at least $ 3$,and
each of which has a multiple pole. Let $\{h_{n}\}$~be a sequence of
meromorphic functions on~$D$, such that~$\{h_{n}\}$~converges
spherically locally uniformly to  a function~$h$ which is
meromorphic and zero-free on $D$. If~$f'_{n}\ne h_{n}$,
then~$\{f_{n}\}$~is normal on~$D$.

Key words: meromorphic function, normal family, sequence of omitted functions
