摘要
利用庞-扎克曼(Pang-Zalcman)引理,研究了与零点个数相关的亚纯函数正规定则。通过反证法和分类讨论,把前人的一个结论推广到一般的微分多项式形式,得到了一个新结果。
With the use of Pang-Zalcman's Lemma,the normality rules of meromorphic functions related to the number of zeros were studied.A new result was obtained by generalising a previous conclusion to the form of general differential polynomials by means of the counterfactual method and categorical discussion was obtained.
