把有穷正级λ的亚纯函数f(z)以∞为Borel例外值看成分类条件,对f(z)不以∞为Borel例外值时,利用复分析方法得到了有穷正级数亚纯函数的Borel方向的判定定理,彻底解决了有穷正级数λ的亚纯函数与其导数必定存在公共的λ级Borel方向问题。
把有窮正級λ的亞純函數f(z)以∞為Borel例外值看成分類條件,對f(z)不以∞為Borel例外值時,利用複分析方法得到瞭有窮正級數亞純函數的Borel方嚮的判定定理,徹底解決瞭有窮正級數λ的亞純函數與其導數必定存在公共的λ級Borel方嚮問題。

With Borel exceptional value∞regarded as the classificational condition, on the contrary the finite positive order λ of meromorphic functions f(z) established a determinant theorem of finite positive order meromorphic func-tions by complex analysis methods, which addresses the problem that there must be λ order Borel direction of public completely in the positive order of meromorphic function and its derivatives.
