Kojima和Takahashi（2012）[5]证明了每个只有有理对数典型奇点的秩为1的法向del Pezzo曲面最多有5个奇点。在本文中，我们确定这样的曲面与五个奇点。
Kojima and Takahashi (2012) [5] proved that every normal del Pezzo surface of rank one with only rational log canonical singular points has at most five singular points. In this paper, we determine such surfaces with five singular points.
