| 摘要: |
| 本文研究了零级亚纯函数Borel方向与Nevanlinna方向的关系.应用Ahlfors覆盖曲面的几何方法,获得了部分零级亚纯函数关于型函数的Borel方向一定是Nevanlinna方向,而这一结果至今未见有文献研究. |

| Abstract: |
| In this article,the relation between Borel directions and Nevanlinna directions for zero-order meromorphic functions is studied.By using Ahlfors' covering surface theory,that Borel directions for certain zero-order meromorphic functions must be Nevanlinna directions is showed. |
| Key words: meromorphic function Nevanlinna direction Borel direction |
